Description

Pliers

Technical field:

The utility model belongs to field of tool, specifically is meant pliers

Background technology:

Pliers class instrument is widely used a kind of apparatus, its purposes of a great variety is different, basic structure function characteristics are to be made the working motion of various needs by associated part such as bearing pin drive tong arms by the folding of the handle that is bowing, when when in general handle is close being pliers work, when being preparation when handle separates, people wish that handle can separate voluntarily so that jaw is in the preparation state in the work of anxiety, and deposit near drawing in convenience at two handles of wishing pliers after hours, do not make the device that handle separates voluntarily or being provided with separating device but is not provided with the gathering closing device but this class instrument of extensively seeing has to be provided with, blemish in an otherwise perfect thing seems.

Summary of the invention:

The purpose of this utility model is the new technical scheme that a kind of pliers class instrument is provided, and it can address the above problem preferably.

The technical solution of the utility model is achieved in that it comprises handle, bearing pin, tong arm, vertically is processed with two chutes that notch is relative in two handle inboards, and being inlaid with spring in the chute is the termination of Telescopic spring.

The beneficial effects of the utility model be can allow pliers handle when needed or voluntarily separately or closed voluntarily.

Description of drawings:

Fig. 1 is the front view of the design's device.Fig. 2 is the rounding state view of the design's device.Fig. 3 is the chute sectional elevation.Among each figure, 1 is handle, and 2 is chute, and 3 is Telescopic spring, and 4 is bearing pin, and 5 is tong arm.

The specific embodiment:

Below in conjunction with accompanying drawing the design is briefly illustrated.

With common pliers be example it generally form by handle 1 bearing pin 4 and tong arm 5, the switching mouth device of the design's pliers class instrument is to be swallow-tailed chute 2 in the inboard of two handles 1 along handle medial surface processing the preceding paragraph cross section, as Fig. 1, shown in Figure 2, the upper end of chute 2 is near the upper end of handle, the lower end of chute is to the middle section position place of handle, chute welds affixed putting in place after can selecting for use the stamping forming processing mode of steel plate to make earlier again, termination, the two ends spring coil of Telescopic spring 3 embeds in the chute 2, Telescopic spring can be in the actuating lower edge of the hand chute up and down termination that moves up and down, when arriving the upper end of chute as shown in Figure 1, because what the physical slot of two handles leaned on is very near herein, the elasticity of elongation power that Telescopic spring 3 can have been given play to about trend herein keeps an open power to two handles, also promptly allows the jawarm members of the other end of handle keep the state of preparation; When Telescopic spring arrives the lower end of chute, because what the physical slot of two handles leaned on is far away herein, Telescopic spring can have been given play to the shrinkage tensions in the middle of the trend herein, then can draw two handles in this moment, so that deposit, be that Telescopic spring 3 possesses two functions that make pliers handle 1 opening and gathering, move parts by shirtsleeve operation and just can realize two kinds of functional purposes.

Claims (1)
