Description

A kind of labor-saving plier

Technical field

The utility model relates to mechanical manufacturing tools field, particularly a kind of labor-saving plier.

Background technology

Existing pliers is generally increase moment, and uses longer tong arm, and such meeting uses and carries all inconvenient.

Utility model content

For the defect of above product, the utility model provides one and is easy to carry, and tong arm is shorter but can provide the labor-saving plier compared with great.

For achieving the above object, the technical solution adopted in the utility model is as follows:

A kind of labor-saving plier, comprise left clamp arm, right clamp arm, rivet, left reinforcement arm, right reinforcement arm, left torque spring, right torque spring, left extension spring and right extension spring, left clamp arm and right clamp arm to be fixed as one structure by rivet, and left clamp arm and right clamp arm can rivet be that axle rotates; Left clamp arm and left reinforcement arm are riveted, and riveted joint place is provided with left torque spring, are also provided with left extension spring in the middle part of left reinforcement arm, and left reinforcement arm is connected with left clamp arm by left extension spring; Right clamp arm and right reinforcement arm are riveted, and riveted joint place is provided with right torque spring, are also provided with right extension spring in the middle part of right reinforcement arm, and right reinforcement arm is connected with right clamp arm by right extension spring.

The utility model has following beneficial effect:

Relative to the utility model like product on market have manufacture simple, portable advantage, and secondary reinforcing is carried out to tong arm by torque spring and extension spring.

Accompanying drawing explanation

Fig. 1 is structure chart of the present utility model;

In figure:

1-left clamp arm, 2-right clamp arm, 3-rivet, the left reinforcement arm of 4-, the right reinforcement arm of 5-, the left torque spring of 6-, the right torque spring of 7-, the left extension spring of 8-, the right extension spring of 9-.

Detailed description of the invention

Please refer to shown in Fig. 1, the utility model provides a kind of labor-saving plier, comprise left clamp arm 1, right clamp arm 2, rivet 3, left reinforcement arm 4, right reinforcement arm 5, left torque spring 6, right torque spring 7, left extension spring 8 and right extension spring 9, left clamp arm 1 and right clamp arm 2 to be fixed as one structure by rivet 3, and left clamp arm 1 and right clamp arm 2 can rivet 3 be that axle rotates; Left clamp arm 1 and left reinforcement arm 4 are riveted, and riveted joint place is provided with left torque spring 6, is also provided with left extension spring 8 in the middle part of left reinforcement arm 4, and left reinforcement arm 4 is connected with left clamp arm 1 by left extension spring 8; Right clamp arm 2 and right reinforcement arm 5 are riveted, and riveted joint place is provided with right torque spring 7, is also provided with right extension spring 9 in the middle part of right reinforcement arm 5, and right reinforcement arm 5 is connected with right clamp arm 2 by right extension spring 9.

Use procedure is as follows:

Left reinforcement arm of holding with a firm grip and right reinforcement arm, left reinforcement arm and right reinforcement arm are compressed left clamp arm and right clamp arm by torque spring and stay cord spring simultaneously, can realize carrying out secondary reinforcing to left clamp arm and right clamp arm.

The above, be only detailed description of the invention of the present utility model, and those of ordinary skill in the art are in the scope that the utility model discloses, and the change that can expect easily, within the protection domain that all should be encompassed in utility model.
