Abstract

The invention discloses platform hole type punching nippers, and belongs to the field of tools. By the punching nippers, manual pore opening operation can be relatively conveniently performed on a thin plate at any time. The technical scheme is that: the nippers comprise a handle, a nipper shaft, a right nipper arm and a left nipper arm, and a compression orifice in the nippers, wherein a compression bar arm in which a stepped compression bar hole is machined is arranged on the right side part of the left nipper arm; a blade tip is machined at the left end of a round bar of which the diameter is slightly less than that of the compression bar hole; a nail head-shaped compression bar is machined at the right end of the round bar; a spherical cavity is machined at the right end of the compression bar; a steel ball is accommodated in the cavity; and a compression spring is sleeved on the compression bar, and the blade tip end of the compression bar is inserted into the compression bar hole leftwards.

Description

Platform cellular type punching nippers

Technical field:

The invention belongs to instrument apparatus field, specifically be meant punching nippers.

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:

Purpose of the present invention is the new technical scheme that a kind of pliers is provided, and it can satisfy above-mentioned needs preferably.

Technical scheme of the present invention be achieved in that it comprise handle, pincers axle, right clamp arm, left clamp arm and on the pressure mouth, the right side of described left clamp arm is divided into the depression bar arm that is processed with the step strut kong; One compares with the strut kong diameter that smaller round bar processes blade tip at its left end, right-hand member is processed as head of a nail shape and becomes depression bar, and the right-hand member head of depression bar also is processed with spherical hollow space simultaneously, accommodates a steel ball in the cavity; The depression bar upper sleeve through has a stage clip, and depression bar blade tip end penetrates in the strut kong left.

The invention has the beneficial effects as follows can be easily to the thin plate drilling operation.

Description of drawings:

Fig. 1 is the whole half sectional view of perforating plier.

Among the 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 is stage clip, and 9 is steel ball, and 10 is right clamp arm, and 11 for clamping axle, and 12 is handle.

The specific embodiment:

The handle 12 of punching nippers, pincers axle 11 are same as handle, the pincers axle of steel wire pliers, as shown in Figure 1, the other end corresponding with handle one end is right clamp arm 10, left clamp arm 1, left clamp arm 1 is faced and is fork-shaped, wherein the right side is divided into the depression bar arm 5 that is processed with transverse circular strut kong 6, and strut kong 6 omits overstriking and is step-like near right-hand member; 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, presses the prong between a mouth arm, the depression bar arm to be material mouth 4; One compares with aforesaid strut kong diameter that smaller bar processes sharp-pointed blade tip at the one end, the other end is processed as head of a nail shape and becomes depression bar 7, and the right-hand member head of depression bar 7 is processed with the cavity of shape as more than half sphere, and cavity is built-in with a smaller steel ball 9; Be with a stage clip 8 on the depression bar, depression bar blade tip end penetrates left in the aforesaid strut kong, and stage clip 8 left ends are supported by the step-like thickened portion in the strut kong, and this part can be held compressed stage clip and make it avoid excessive compression during punching press; Then left and right sides tong arm can be close synchronously in the middle of relying on to hold fixed handle 12 during operation, right clamp arm 10 can by steel ball 9 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, the 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; The coordination of the circular-arc movement locus of tong arm and the straight-line trajectory of depression bar in strut kong is then finished by the rolling movement of the steel ball 9 of depression bar 7 right-hand member end faces, the transmission operating pressure that steel ball can up and down reciprocatingly roll and coordinate at its inner face of the pressure lower edge of right clamp arm during work, the elastic force of finishing a punching press rear compression spring 8 can unclamp the head of a nail part of back by depression bar 7 in the power of holding and strut left and right sides tong arm automatically in order to punching press next time.

Claims

1. platform cellular type punching nippers, it comprise handle, pincers axle, right clamp arm, left clamp arm and on the pressure mouth, it is characterized in that the right side of left clamp arm is divided into the depression bar arm that is processed with the step strut kong; One compares with the strut kong diameter that smaller round bar processes blade tip at its left end, right-hand member is processed as head of a nail shape and becomes depression bar, and the right-hand member head of depression bar also is processed with spherical hollow space simultaneously, accommodates a steel ball in the cavity; The depression bar upper sleeve through has a stage clip, and depression bar blade tip end penetrates in the strut kong left.
