DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clipping tool and a crimping tool for performing work by opening and closing two handles.

[0002]

2. Description of the Related Art A conventional pinching tool or crimping tool is disclosed in Japanese Patent Application Laid-Open No. 9-29648 by the present inventor. In other words, the force for pinching by changing the position of the fulcrum can be changed in a plurality of stages.

[0003]

However, in the conventional pinching tool or crimping tool, since the length of the crimping portion is limited by the position of the fulcrum, it cannot be processed at a deep position in the portion to be processed. There was a problem.

An object of the present invention is to solve such a problem, and an object of the present invention is to provide a pinch type tool and a crimping tool which can be processed at a deep position of a workpiece.

[0005]

In order to achieve the above object, a pinching tool according to the present invention has a first handle, a second handle, and a support shaft; the first handle has a handle at one end. Having an action portion on the other end side, the action portion is continuous with a groove formed in the direction of the handle, and has a projection facing the slot on the other end side of the handle, The projecting portion has a mounting hole; the second handle has a handle on one end side, has an action portion on the other end side, and has a mounting hole on the other end side of the handle; The first handle and the second handle are attached by being inserted into the respective mounting holes; the slot of the first handle is open in communication with the distal end of the operating portion with each handle open. Features.

The pinching tool according to the present invention may be a pinching tool, a pair of pliers, a nail, a vice, or any other tool that works by opening and closing two handles. The action section may be a cutting section, a crimping section, a holding section, or any other action section depending on the type of the pinching tool. The handle is preferably provided with a non-slip. In the pinch type tool according to the present invention, the support shaft may be formed by a pinion, a rack may be formed on the first handle, and the support shaft of the pinion may be engaged with the rack. It is preferable that the first handle has a stopper to prevent the support shaft from falling off. It is preferable that a washer is attached to the support shaft with the first handle and the second handle interposed therebetween.

In the pinch type tool according to the present invention, the processing portion is inserted from the tip of the working portion to the slot with the handles of the first handle and the second handle opened, and each handle is opened and closed. It can be carried out. By inserting the workpiece to the slot, processing can be performed at a deep position in the workpiece.

[0008] A crimping tool according to the present invention has a first handle, a second handle, and a support shaft; the first handle has a handle at one end and a crimp portion at the other end; The crimping portion is continuous with a groove formed in the direction of the handle, has a protrusion facing the groove on the other end side of the handle, and the protrusion has a mounting hole; Has a handle on one end side, has a crimp portion on the other end side, and has a mounting hole on the other end side of the handle;
The support shaft is inserted and mounted in each mounting hole of the first handle and the second handle; each of the crimp portions of the first handle and the second handle has a crimp surface that overlaps each other when each handle is closed. The slot of the first handle is open in communication with the tip of the crimping portion with each handle open.

In the crimping tool according to the present invention, with the handles of the first handle and the second handle opened, the workpiece is inserted from the tip of the crimping portion to the slot to open and close each handle, and the crimping process is performed. It can be performed. By inserting the workpiece to the slot, the press-bonding process can be performed at a deep position of the workpiece.

Embodiments of the present invention will be described below with reference to the drawings. 1 to 3 show an embodiment of the present invention. As shown in FIGS. 1 to 3, the crimping tool 1 includes a first handle 2, a second handle 3, a pinion 4, and a washer 5. The crimping tool 1 is a tool commonly referred to as “tsukami”, and is used, for example, when roofing a tin roof, when a plurality of stacked galvanized sheets are crimped at the ends and bent and caulked. It is.

The first handle 2 has a handle 11 at one end and an action portion (crimp portion) 12 at the other end. The handle 11 is provided with a non-slip 11a. The action section 12
The width of the distal end side 12a is increased, and a crimping surface 12b is provided on the inner surface. The crimping surface 12b is continuous with the slot 13 formed in the direction of the handle 11. 1st handle 2
Has a protruding portion 14 facing the slot 13 on the other end side of the handle 11 (on the side of the crimping portion 12). The protruding portion 14 is attached to the mounting hole 15.
have. The mounting hole 15 has an oval cross section on one side 15a and a rack 1 on the inner side of the handle 11 on the opposite side 15b.
6.

The second handle 3 has a handle 21 on one end and an action portion (crimping portion) 22 on the other end. The handle 21 is provided with a non-slip 21a. The action part 22
The width of the distal end side 22a is increased, and the inner side has a crimping surface 22b. The second handle 3 has a mounting hole 23 on the other end side of the handle 21 (on the side of the crimp portion 22). The mounting hole 23 has a rectangular cross section.

The pinion 4 is provided in the mounting hole 1 of the first handle 2.
5 is inserted into the mounting hole 23 of the second handle 3 and penetrated therethrough, and is fixed by the washer 5. The pinion 4 is the tip side 4
a has a rectangular cross section and is fixed to the mounting hole 23 so as not to rotate. The pinion 4 separates from the operating portion 12 of the first handle 2 when the handles 11 and 21 are opened, and
When the cover 21 is closed, it is engaged with the rack 16 so as to approach the action section 12 of the first handle 2 as shown in FIG. First
The slot 13 of the handle 2 is open in communication with the distal end 12a of the action section 12 with the handles 11 and 21 opened.
When the handles 11 and 21 are closed, the crimping surfaces 12b and 22 of the first handle 2 and the second handle 3, as shown in FIG.
b overlap each other.

Next, the operation will be described. The crimping tool 1 includes a handle 1 of each of the first handle 2 and the second handle 3.
When 1 and 21 are opened, they are opened with the pinion 4 as a fulcrum.
At this time, the pinion 4 meshes with the rack 16 and rotates in a direction away from the action portion 12 of the first handle 2, and
2b and 22b are easily opened greatly. Each pattern 11, 21
In the state in which the opening is opened, the end to be caulked of the work part, for example, the tin roof, is moved to the tip side 1 of the action parts 12 and 22.
Each handle 11, 21 is inserted from 2 a, 22 a to slot 13.
Can be opened and closed to perform processing. Slot 1 to be processed
By inserting up to 3, processing can be performed at a deep position in the processed portion.

As shown in FIG. 3, when the handles 11 and 21 of the first handle 2 and the second handle 3 are closed, the pinion 4 engages with the rack 16 and the action portion 1 of the first handle 2 is closed.
2, the distance between the point of force of the handles 11 and 21 (the position where the grip is applied) and the pinion 4 serving as the fulcrum increases, and a large force is applied to the crimping surfaces 12 b and 22 b in the direction in which they overlap each other. It will be easier. As described above, since the pinion 4 of the fulcrum engaging with the rack 16 moves each time the handles 11 and 21 are opened and closed, the crimping tool 1 can be used without changing the position of the fulcrum every time the work is performed. 12b, 22b
Can be easily opened greatly, and the pinching force can be easily changed. Thus, the tin roof can be easily caulked.

[0016]

According to the clipping tool and the crimping tool of the present invention, since the working portion is continuous with the groove formed in the direction of the handle, the working portion is operated in a state where each handle is opened. The processing can be performed at a deep position of the workpiece by inserting from the tip of the part to the slot.
