Problems solved by technology

[0002] Nowadays, there are more and more occasions where belts need to be punched, and ordinary belt punchers still have some shortcomings in punching belts: for example, most belt punchers can only punch one belt at a time. The hole and the distance of the hole cannot be adjusted. It is inconvenient and inaccurate to manually measure or visually measure the hole in the middle position of the belt. At the same time, there is no pressing device, so the object to be punched will move when punching. And then affect the accuracy of punching

Abstract

The invention relates to a novel hole puncher which comprises a base, a sliding block, a handle, a fixed shaft A, a pressing plate A, a pressing plate B, a fixed shaft B, a template, locking rods, punching pins, a fixed block, bolts, centralizing springs and centralizing sliding blocks, wherein a slot is formed inside the sliding block and can be used for accommodating a plurality of punching pins; pitch adjusting holes are formed in two sides outside the slot; scales are labeled on the pitch adjusting holes; threaded holes are formed in the middle positions of two side faces at the upper part of punching pins, and each threaded hole is matched with one locking rod, so that the punching pins of which the positions are adjusted are fixed; strip-shaped objects can be pressed by the pressing plate A and the pressing plate B; and the centralizing sliding blocks can automatically find symmetrical center lines of the corresponding strip-shaped objects under the action of the centralizing springs. The novel hole puncher disclosed by the invention is suitable for punching the strip-shaped objects and has the beneficial effects that punching quantity can be changed; the distance between every two punching pins can be accurately adjusted, so that the punching efficiency is improved; and the novel hole puncher is simple in operation and convenient in carrying.
