Abstract

The utility model discloses pipe tongs. The pipe tongs comprise a left tongs handle in which a spring I is arranged, a right tongs handle in which a spring II is arranged, a guide plate, a movable tongs head which is provided with a groove, and a fixed tongs head, wherein the left tongs handle is fixedly connected with the fixed tongs head through the guide plate; a connecting rod is arranged between the left tongs handle and the right tongs handle, and is fixedly connected to the tops of the spring I and the spring II; the top of the right tongs handle is wedged into the groove of the movable tongs head; the guide plate is clamped into the movable tongs head; a V-shaped cut is formed at the upper end of the movable tongs head, and a guide block is arranged at the lower end of the movable tongs head; a cut which is opposite to the cut on the movable tongs head is formed at the upper end of the fixed tongs head; and the movable tongs head and the fixed tongs head form a jaw. The pipe tongs have a simple structure and can be safely and conveniently used; the V-shaped jaw increases the friction between the pipe tongs and a workpiece, so that a slip phenomenon can be well prevented; and the movable tongs head can automatically reset to the original position after the operation is finished every time, so the pipe tongs can be easily and quickly operated.

Description

Pipe vice

Technical field

The utility model relates to a kind of hardware & tools, relates in particular 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; 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 provide a kind of can easily quick clamping work pieces, and have automatically reset pipe vice.

The purpose of the utility model realizes through following technical scheme: comprise a movable binding clip and a fixed pliers head that the left side pincers handle that is built-in with spring one, the right side pincers handle that is built-in with spring two, a guide plate, offer groove, said left side pincers handle is fixedly connected with fixed pliers head through guide plate; Be provided with a connecting rod between said left side pincers handle and the right pincers handle, this connecting rod is fixed on the top of spring one and spring two; The top of said right pincers handle is wedged in the groove of said movable binding clip; Said guide plate is connected in the said movable binding clip; The upper end of said movable binding clip offers the V notched cut, and the lower end is provided with a guide pad; Said fixed pliers head upper end offer with said movable binding clip on the corresponding otch of otch; Said movable binding clip and fixed pliers head constitute jaw.

Be provided with helical teeth on said movable binding clip of the utility model and the fixed pliers head.

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 simple in structure, safe and convenient to use, and V font jaw has increased the frictional force with workpiece, can be good at preventing the generation of skidding; 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 a movable binding clip 4 and a fixed pliers head 5 that the left side pincers handle 1 that is built-in with spring 1, the right side pincers handle 2 that is built-in with spring 2 14, a guide plate 3, offer groove 7, said left side pincers handle 1 is fixedly connected with fixed pliers head 5 through guide plate 3; Be provided with a connecting rod 6 between said left side pincers handle 1 and the right pincers handle 2, this connecting rod 6 is fixed on the top of spring 1 and spring 2 14; The top of said right pincers handle 2 is wedged in the groove 7 of said movable binding clip 4; Said guide plate 3 is connected in the said movable binding clip 4; The upper end of said movable binding clip 4 offers V notched cut 8, and the lower end is provided with a guide pad 9; Said fixed pliers head 5 upper ends offer with said movable binding clip 4 on the corresponding otch of otch; Said movable binding clip 4 constitutes jaw 10 with fixed pliers head 5.

Be provided with helical teeth 11 on said movable binding clip 4 and the fixed pliers head 5.

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

Initial position, the spring 2 14 in spring 1 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 10; Hold left side pincers handle 1 and right pincers handle 2 and compression, because the effect of connecting rod 6, spring 1 receives force compresses; Spring 2 14 receives tensile, and the top promotion activity binding clip 4 of right pincers handle 2 slides along guide plate 3 to the right, until jaw 10 clamping work pieces that are made up of said movable binding clip 4 and fixed pliers head 5; Said otch 8 has increased the contact area of jaw 10 with workpiece, has increased mutual frictional force, exerts oneself a little again; With regard to ability easy removal pipe, parbuckle screw, nut and clamp are dismantled various five metals workpiece;

Behind the complete operation, discharge with right pincers handle 2 as long as handle 1 is clamped on a left side, spring 1 by compression and the spring that is stretched 2 14 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.
