Abstract

The utility model discloses a pair of front sliding shaft type pliers capable of punching holes through compression, belonging to the field of tools. The pair of pliers can conveniently perform manual hole punching operation to thin plate at any time, and is realized through adopting the technical scheme that handles and a spring are comprised; ends corresponding to one end of one handle and one end of the other handle serve as a left clamping arm and a right clamping arm respectively; the left clamping arm is Y-shaped from a front view, the right part of the Y shape is a compressed rod arm processed with a compressed rod hole, a vertical long hole (i.e. a slide shaft hole) is processed at the top of the compressed rod arm, and the left part of the Y shape is a compressed port arm processed with a compressed port; the right clamping arm is also Y-shaped from a looking-down view, and is processed with a hole positioned at the upper part and used for a clamping shaft to penetrate and a compressed shaft hole positioned at the lower part and used for a compressed shaft to penetrate; a blade point is processed at one end of a round rod and a radial through hole is processed at the other end of the round rod for the compressed shaft and the compressed rod to penetrate, the compressed rod penetrates into the compressed rod hole and the compressed shaft penetrates into the compressed shaft hole and are movably riveted, and the left clamping arm and the right clamping arm are hinged through the clamping shaft and a hole at the top.

Description

Preceding sliding shaft is pressed the hole pincers

Technical field:

The utility model belongs to instrument apparatus field, specifically is finger pressure hole pincers.

Background technology:

In many processing operations place, by the not so good operation of electric drill punching, also take electric power at thin plate (thick about about 0.1) thin soft as pattern more, could utilize the principle of work and power of pliers to come manual simply and easily punching, need to develop.

Summary of the invention:

The purpose of this utility model is the new technical scheme that a kind of pliers is provided, and it can satisfy above-mentioned needs preferably.

The technical solution of the utility model is to realize like this, it comprises handle, spring, the other end corresponding with handle one end is respectively left clamp arm, right clamp arm, left clamp arm is faced and is fork-shaped, wherein the right side is divided into the depression bar arm that is processed with strut kong, being processed with vertical elongated hole near the top of depression bar arm is the slide-bar hole, and left part is to be processed with the pressure mouth arm of pressing mouth; Right clamp arm also is fork-shaped overlooking under the state, be processed with respectively by the hole of last penetrated pincers spool and by under the last item hole of penetrated last item; One round bar processes sharp-pointed blade tip at the one end, the other end is processed with through hole radially and penetrates last item and becomes depression bar, and depression bar penetrates that last item then penetrates the movable riveted joint last item hole in the strut kong, and left and right sides tong arm is hinged by the hole realization on pincers axle and top.

The beneficial effects of the utility model be can be whenever and wherever possible to the thin plate attended operation of punching, very simple and convenient.

Description of drawings:

Fig. 1 is that the design presses hole pincers front view.

Among each figure, 1 is left clamp arm, and 2 is to press a mouthful arm, and 3 is to press mouth, and 4 are the material mouth, and 5 is the depression bar arm, and 6 is strut kong, and 7 is depression bar, and 8 for clamping axle, and 9 is the slide-bar hole, and 10 is last item, and 11 is right clamp arm, and 12 is spring, and 13 is handle.

The specific embodiment:

As shown in Figure 1, press the hole to clamp the spring 12 that comprises between handle 13 and the handle, the other end corresponding with handle one end is respectively left clamp arm 1, right clamp arm 11, left clamp arm is faced and is fork-shaped, preferably monoblock cast, wherein the right side is divided into the depression bar arm 5 that is processed with strut kong 6, and also being processed with vertical elongated hole near the top of depression bar arm is slide-bar hole 9, left part is to be processed with the pressure mouth arm 2 of pressing mouth 3, presses mouth 3 and strut kong 6 concentric with the footpath; Right clamp arm 11 and right side handle are flute profile by the cold drawing drawing preferably, and its top also is fork-shaped overlooking under the state, are processed with the last item hole of pincers axis hole that keeps left and the penetrated last item 10 of keeping right respectively at the cell wall position; Compare with aforesaid strut kong 6 diameters with one that smaller round bar processes sharp-pointed blade tip at the one end, the other end is processed with through hole radially and penetrates 10 one-tenth depression bars of last item 7, depression bar 7 penetrates 10 of last items in the strut kong 6 and penetrates movable riveted joint in the last item hole on the right clamp arm 11, and 1,11 of left and right sides tong arms are realized hinged by the holes on pincers spools 8 and top.Like this, holding fixed handle 13 relies on middle, then left and right sides tong arm can be close synchronously, right clamp arm 11 can by last item 10 to depression bar 7 exert pressure make press to left in its strut kong 6 on depression bar arm 5 over against pressure mouth arm 2 on pressure mouth 3, thin plate material in the material mouthfuls 4 just can die cut be portalled with pressing mouthfuls 3 acting in conjunction by the blade tip end of depression bar 7, and the coordination of the circular-arc movement locus of tong arm and the straight-line trajectory of depression bar in strut kong is finished by the sliding motion between near microscler slide-bar hole 9 depression bar arm 5 tops and the pincers axle 8; The elastic force of finishing a punching press rear spring 12 can strut left and right sides handle automatically after the power of holding is unclamped, 11 of right clamp arms can drive depression bar 7 synchronous returns by last item 10 and be separated from material mouth 4 in order to punching press next time.

Claims

1. sliding shaft is pressed the hole pincers before one kind, it comprises handle, spring, it is characterized in that the other end corresponding with handle one end is respectively left clamp arm, right clamp arm, left clamp arm is faced and is fork-shaped, wherein the right side is divided into the depression bar arm that is processed with strut kong, being processed with vertical elongated hole near the top of depression bar arm is the slide-bar hole, and left part is to be processed with the pressure mouth arm of pressing mouth; Right clamp arm also is fork-shaped overlooking under the state, be processed with respectively by the hole of last penetrated pincers spool and by under the last item hole of penetrated last item; One round bar processes sharp-pointed blade tip at the one end, the other end is processed with through hole radially and penetrates last item and becomes depression bar, and depression bar penetrates that last item then penetrates the movable riveted joint last item hole in the strut kong, and left and right sides tong arm is hinged by the hole realization on pincers axle and top.
