TECHNICAL FIELD OF THE INVENTION
[0003]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a punch for punching two or multiple holes for binding in a paper sheet.
[Prior art]
[0004]
Conventionally, various types of punches have been available, but replacement of the punching rod has been troublesome.
[Problems to be solved by the invention]
[0005]
An object of the present invention is to improve the value of utilization as a perforator by allowing only a perforating rod to be detachably detachable from a main body with respect to a conventional perforator.
[Means for Solving the Problems]
[0006]
The means of the present invention are as follows.
[0007]
A guide for the piercing rod holder, which comprises a piercing rod pusher supported on the base via an operation handle, and a pair of piercing rod holders separate from the piercing rod pusher, and which is detachably attached to the lower end of the piercing rod pusher. The piercing rod is inserted into the hole and received by the bulging head, and the piercing rod holder further allows the bulging head of the piercing rod to move slightly in the horizontal direction, and also opens the lock pin receiving hole. And a lock pin, and an operating piece for removing the upper oblique piece of the lock pin by the lowering action of the coil spring is provided integrally with the lock pin.
BEST MODE FOR CARRYING OUT THE INVENTION
[0008]
In the figure, reference numeral 1 denotes a base, 2 denotes a pair of left and right side frames standing on the front end of the base 1, and 3 denotes a known center gauge provided on the upper surface of the base 1 and is mounted on the left and right sides of the base 1 so as to be able to move forward and backward. I have. (Internal structure is omitted.) Reference numeral 4 denotes a handle reinforcing plate pivotally attached to the side frame 2 with the shaft 5, and a U-shaped handle is covered and fixed to the reinforcing plate 4, and a hole is accommodated in the guide gap 7 of the side frame 2. The upper end of the rod pusher 9 is pivotally connected by a pin 10, and the perforated rod pusher 9 moves up and down by operating the handle 6.
In the present invention, the perforated rod push 9 and the perforated rod holder 13 are separated from each other, and the pair of left and right perforated rod holders 13 are removably inserted into the recessed portions 12 at the lower end of the perforated rod press 9. Then, the piercing rod 15 is inserted into the guide hole 14 formed in the piercing rod holder 13 and received by the bulging head 16. As shown in FIGS. 7 to 9, the piercing rod holder 13 has a lock pin receiving hole 17 in the holder 13, and a coil spring 18 and a lock locking rod 19 are inserted into the hole 13 so that the upper end oblique piece 19 ′ of the locking rod 19 is inserted. It is pushed up and exposed by the coil spring 18. When the operating piece 20 integrated with the locking rod 19 is loosely fitted into the narrow groove 23 provided continuously with the lock pin receiving hole 19 and the operating piece 20 is pressed down against the pushing up force of the coil spring 18, the locking rod The oblique upper end 19 'of the lower part 19 is lowered and the locking rod 19 is disengaged from the piercing rod pusher 9 and the piercing rod holder 13 is freely detachable from the lock pin receiving hole 17 and has a novel operation effect which does not exist in the conventional punch. Play.
【The invention's effect】
[0009]
According to the present invention, the replacement of the piercing rod can be performed quickly and easily due to the presence of the independent piercing rod holder, and the value as this kind of piercing device is enhanced. Also, different diameters of perforated rods are attached, and the range of use is wide.
