The knob 5 of the clip 6 is fixed to the slider body 3c by a leg 5a extending downward through the slit 2. The engaging portion 4a may be a convex portion that can be inserted into the engaged portion 2a. However, in consideration of the operability at the time of extension and storage, the engaging portion 4a is curved or inclined. Desirably, it consists of a plane. Further, from the viewpoint of preventing the rod-shaped object A from being retracted, it is desirable that the projection 3d serving as the locking portion has a curved surface or an inclined surface in the feeding direction and a substantially vertical surface in the housing direction. Further, the cross-sectional shape of the shaft cylinder 1 may be any other appropriate shape such as a cylindrical shape, a square shape, or a flat shape. In the rod feeding device of the present embodiment, the lower portion of the retraction preventing portion 3b is in contact with the inner wall of the barrel 1, so that the force of the resilient member 4 can be maintained even if it is left for a long time. Will not be depressed. Therefore, when used, that is,
In a state where the rod-shaped material A protrudes and is in contact with the paper surface or the like, when a reaction force equivalent to the pressing force on the paper surface is applied, the retraction preventing portion 3b receives the clamping force by the mounting portion 3a and the slider body 3c, and The engaging portion 2a and the convex portion 3d, which is a locking portion, form a locked state. Thereby, the retraction of the rod A can be prevented. When the rod-shaped material A is separated from the paper surface after use, the reaction force is also lost.
b returns to the original state, the locked state between the engaged portion 2a and the convex portion 3d as the locking portion is released, and the rod-shaped material A can be easily accommodated. Next, referring to FIG. 5 to FIG.
An embodiment will be described. In the following embodiments, the same reference numerals in the drawings are used for the same members and portions as those in the first embodiment unless otherwise specified. The second embodiment is the same as the first embodiment except that the sliding portion 3h is provided with a sliding portion 3h composed of a convex portion substantially at the center of the lower wall surface of the retracting portion 3b. The effect is substantially the same as that of the first embodiment. In the rod feeding device according to the present embodiment, the leg 4b of the elastic body 4 abuts on the anti-retraction portion 3b on the left side of the sliding portion 3h formed of a convex portion, and the convex portion 3 serving as a locking portion.
d is located on the right side of the sliding portion 3h (see FIG. 8). Therefore, when left for a long time, the leg 4b and the retract
The force applied to the contact point with b acts as a counterclockwise force on the convex portion 3d serving as the locking portion with the sliding portion 3h as a fulcrum (see FIG. 9). Therefore, the convex portion 3d, which is the locking portion, is at a position higher than the original position, and the gradient of the plate-shaped portion 3f is increased. It is easy to be displaced to the outside in the radial direction, and it is easy to form a locked state between the engaged portion 2a and the convex portion 3d, which is a locking portion, and it is possible to prevent the rod A from being retracted (see FIG. 10). Further, in the present embodiment, since the sliding portion 3h of the retraction preventing portion 3b is a convex portion, the retraction preventing portion 3b is formed.
Since the contact area between b and the inner wall of the barrel 1 is small, the slider 3 can be moved with a small force when the rod-shaped object A comes and goes. Next, a third embodiment will be described with reference to FIGS. The third embodiment is different from the second embodiment in that the sliding portion 3h formed of the convex portion is replaced with the convex portion 3 serving as a locking portion.
The second embodiment is the same as the second embodiment except that it is provided immediately below d.
The operation and effect are substantially the same as those of the second embodiment. In the rod feeding device of the present embodiment, the leg 4b of the elastic body 4 abuts on the anti-retraction portion 3b on the left side of the sliding portion 3h formed of the convex portion, and the convex portion 3d as the locking portion slides. It is located directly above the portion 3h (see FIG. 13). Therefore, if left for a long time,
The force applied to the contact point between the leg 4b and the retraction preventing portion 3b acts as a counterclockwise force on the convex portion 3d serving as the locking portion with the sliding portion 3h as a fulcrum (see FIG. 14). At this time, the convex portion 3d serving as the locking portion is located at a position slightly lower than the original position, and the gradient of the plate portion 3f is also reduced. However, since the inclination of the plate-like portion 3f does not disappear because of the sliding portion 3h formed of the convex portion, when the reaction force acts on the rod-shaped material A, the retracting prevention portion 3b is moved in the radial direction. The rod A is displaced outward to form a locked state between the engaged portion 2a and the convex portion 3d, which is a locking portion, so that the rod A can be prevented from being retracted (see FIG. 15). Next, a fourth embodiment will be described with reference to FIGS. The fourth embodiment is different from the second embodiment in that the sliding portion 3h made of a convex portion is replaced with the retractable portion 3b.
It is the same as the second embodiment except that it is provided on the side of the mounting portion 3a, and the operation and effect are substantially the same as those of the second embodiment. In the rod feeding device of the present embodiment, the leg 4b of the elastic body 4
Is in contact with the anti-retraction portion 3b on the right side of the sliding portion composed of the convex portion, and the convex portion 3d as the locking portion is located further to the right of the contact portion (see FIG. 18). Therefore, when the leg 4b is left for a long time, the force applied to the contact point between the leg 4b and the retraction preventing portion 3b acts as a clockwise force on the convex portion 3d serving as the locking portion with the sliding portion 3h as a fulcrum. See FIG. 19). At this time, the convex portion 3d serving as the locking portion is located at a position slightly lower than the original position, and the gradient of the plate portion 3f is also reduced. However, since the inclination of the plate-like portion 3f does not disappear because of the sliding portion 3h formed of the convex portion, when the reaction force acts on the rod-shaped material A, the retracting prevention portion 3b is moved in the radial direction. The rod-shaped material A is displaced outward to form a locked state between the engaged portion 2a and the convex portion 3d, which is a locking portion, so that the rod A can be prevented from being retracted (see FIG. 20). Next, a fifth embodiment will be described with reference to FIGS. The fifth embodiment is different from the second embodiment in that the mounting portion 3a of the slider 3 and the retraction preventing portion 3b
An elastic plate-shaped portion 3e is formed so as to have an inclination on the side close to the engaged portion 2a, and an elastic plate-shaped portion 3f connecting the retractable portion 3b and the slider body 3c is formed. It is on the side facing the engaged portion 2a. Therefore, the second embodiment is the same as the second embodiment except that the protrusion 3d serving as the locking portion is formed on the mounting portion 3a side of the retracting prevention portion 3b, and the operation and effect are substantially the same as those of the second embodiment. It is. In the rod feeding device according to the present embodiment, the leg 4b of the elastic body 4 comes into contact with the anti-retraction part 3b on the right side of the sliding part 3h formed of the convex part, and the convex part 3d as the locking part slides. Part 3h
(See FIG. 23). Therefore, when the leg 4b is left for a long time, the force applied to the contact point between the leg 4b and the retraction preventing portion 3b acts as a clockwise force on the convex portion 3d serving as the locking portion with the sliding portion 3h as a fulcrum. Therefore, the convex portion 3d, which is the locking portion, is at a position higher than the original position, and the inclination of the plate-shaped portion 3e is increased. It is easy to be displaced outward in the radial direction, and it is easy to form a locked state between the engaged portion 2a and the convex portion 3d, which is a locking portion, so that the rod A can be prevented from being retracted (see FIG. 24). Next, a sixth embodiment will be described with reference to FIGS. The sixth embodiment is different from the second embodiment in that the mounting portion 3a of the slider 3 and the retraction preventing portion 3b
And a plate-like portion 3e having elasticity for connecting the retractable portion 3b and the slider body 3c are formed on the side close to the portion to be joined 2a. Therefore, except that the convex portion 3d as the locking portion is formed substantially at the center of the retraction preventing portion 3b,
This is the same as the second embodiment, and the operation and effect are substantially the same as those of the second embodiment. In the rod feeding device of this embodiment, the leg portion 4b of the elastic body 4 is in contact with the retracting prevention portion 3b just above the sliding portion 3h formed of a convex portion (see FIG. 27). Therefore, the retraction preventing portion 3b does not move downward even if left for a long time. Therefore, the position of the projection 3d, which is the locking portion, does not change, and the gradient of the plate-shaped portions 3e, 3f does not change. Disengaged part 2a
And the projection 3d, which is a locking portion, can be locked to prevent the rod A from being retracted (see FIG. 28). In the above embodiment, the sliding portion 3h is formed integrally with the retraction preventing portion 3b. However, a separate component is connected to the retraction preventing portion 3b by an appropriate method such as bonding or screwing. May be provided. Further, as this separate member, an elastic member such as rubber, a plate spring or a coil spring may be selected. According to the present invention, the rod feeding device according to the present invention has the above-mentioned structure, so that the retracting prevention mechanism works effectively even if it is left for a long period of time. Unintentional retraction can be prevented. not to mention,
