Description

Multi-functional pipe pincers

Technical field

The utility model relates to a kind of hardware & tools, refers more particularly to a kind of pipe vice.

Background technology

At present the jaw of existing pipe vice is two working faces parallel to each other, and less with the contact-making surface of workpiece during use, frictional force is restricted, and is prone to the generation skidding; The cutting pipe is relatively required great effort; Jaw does not have auto-reset function, and each use all must manually be drawn jaw or open in, and operation is very inconvenient, inefficiency.

Summary of the invention

The purpose of the utility model is to overcome the deficiency that prior art exists, and can clamp and the fly-cutting workpiece and provide a kind of, has the pipe vice of auto-reset function.

The purpose of the utility model realizes through following technical scheme: comprise left side pincers handle, the right movable binding clip that clamps handle, guide plate, fixed pliers head and offer a groove, said left side pincers handle is fixedly connected with fixed pliers head through guide plate; Said right pincers handle and guide plate are hinged; Said left side pincers handle is provided with spring with right the pincers in the handle, and two springs are fixedly connected with the two ends of a connecting rod respectively; The top of said right pincers handle is wedged in the groove of said movable binding clip; The upper end of said movable binding clip is provided with a blade, and the lower end is provided with a guide pad, and whole movable binding clip and guide plate clamping; Be provided with helical teeth on said movable binding clip and the fixed pliers head, and both constitute jaw.

Also be provided with a scale plate on the said guide plate of the utility model.

The beneficial effect of the utility model is: it is simple in structure, and is safe and convenient to use, blade ability fly-cutting workpiece; Every completion once-through operation, movable binding clip can automatically reset to the home position, and operation is easily fast.

Fig. 2 is the structural representation after Fig. 1 removes scale plate.

Fig. 3 is the structural representation of the said movable binding clip of the utility model.

The specific embodiment

To combine accompanying drawing that the utility model is done detailed introduction below: like Fig. 1,2, shown in 3; Comprise left side pincers handle 1, the right movable binding clip 5 that clamps handle 2, guide plate 3, fixed pliers head 4 and offer a groove 7, said left side pincers handle 1 is fixedly connected with fixed pliers head 4 through guide plate 3; Said right pincers handle 2 is hinged with guide plate 3; Said left side pincers handle 1 is provided with spring with right the pincers in the handle 2; Said spring comprises spring 1 that is arranged in the right pincers handle 2 and the spring 2 14 that is arranged in the left side pincers handle 1, and two

springs

13,14 are fixedly connected with the two ends of a connecting rod 6 respectively; The top of said right pincers handle 2 is wedged in the groove 7 of said movable binding clip 5; The upper end of said movable binding clip 5 is provided with a blade 8, and the lower end is provided with a guide pad 9, and whole movable binding clip 5 and guide plate 3 clampings; Be provided with helical teeth 10 on said movable binding clip 5 and the fixed pliers head 4, and both constitute jaw 11.

Also be provided with a scale plate 12 on the said guide plate 3.

Initial position, the spring 1 in spring 2 14 in the left side pincers handle 1 and the right pincers handle 2 is does not have the no extended state of compression, and workpiece is inserted jaw 11; Hold left side pincers handle 1 and right pincers handle 2 and compression, because the effect of connecting rod 6, spring 1 receives tensile; Spring 2 14 receives force compresses, and the top promotion activity binding clip 5 of right pincers handle 2 slides along guide plate 3 to the right, until jaw 11 clamping work pieces that are made up of said movable binding clip 5 and fixed pliers head 4; Exert oneself a little, with regard to ability easy removal pipe, parbuckle screw, nut and clamp are dismantled various five metals workpiece again; Said blade 8 is sheared function in addition, can 205mm steel wire once easily be cut off;

Behind the complete operation, discharge with right pincers handle 2 as long as handle 1 is clamped on a left side, spring 2 14 by compression and the spring that is stretched one 13 equal self-recoveries are to nature; Simultaneously, movable binding clip 5 is because the promotion at right pincers handle 2 tops all is returned to initial position.

Certainly, above-mentioned explanation is not the restriction to the utility model, and the utility model also is not limited to above-mentioned giving an example; Those skilled in the art; In the scope of the utility model, the variation of making, change and add or replacement, all should belong to the protection domain of the utility model.
