Description

A kind of pipe vice

The utility model relates to a kind of pliers, relates in particular to a kind of pipe vice.

The utility model is to improve on the basis of existing III swaged forging handle pipe vice and come, the regular jaw of existing III swaged forging handle pipe vice is connected as a single entity with the pincers handle, create by same material integral body, because material therefor must at first satisfy the required high strength of regular jaw tooth portion, the quality requirements of high rigidity, so whole parts forge by quality carbon steel and form, thereby wasted steel, strengthened manufacturing cost.In assembling process, must intert in the pincers cover with the afterbody (grip portions) of whole parts and be hinged in addition, this makes the grip portions of pincers handle can't make suitable thickness, and when having increased work to the pressure of staff, thereby it is poor to cause gripping feel, be unfavorable for the performance of manpower.

The purpose of this utility model be to overcome the deficiency of above-mentioned prior art and provide a kind of save steel, cost low, grip good hand touch, help the pipe vice of manpower performance.

The purpose of this utility model can reach by following measure: a kind of pipe vice, it comprises moving jaw, and moving jaw links to each other with the pincers cover by nut, it is characterized in that the pincers cover connects a pincers handle, the head of pincers handle connects a regular jaw, is connected with flat spring on the pincers handle.

The utility model can produce following good effect compared with the prior art: because regular jaw of the present utility model and pincers handle are that split links together, thereby it accounts for the cast iron manufacturing that heavy weight extremely pincers shank portion can adopt relative low price, thereby saved steel, reduced production cost.And when assembling, can change assembly direction, rivet with regular jaw again after the head that clamps handle is interted in the pincers cover, can make suitable thickness, improve the gripping feel, help the performance of manpower so clamp the grip portions of handle.

Below in conjunction with accompanying drawing preferred forms of the present utility model is elaborated:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the A-A cutaway view of Fig. 1.

Embodiment: a kind of pipe vice, it comprises moving jaw 1, the afterbody of moving jaw 1 is threaded, moving jaw 1 links to each other with pincers cover 5 by the nut 6 that its afterbody is with, be inserted with a pincers handle 7 in the pincers cover 5 and be attached thereto by rivet 4, the head of pincers handle 7 connects a regular jaw 2 by resilient key 3, is fixed with two flat springs 8 with rivet on the pincers handle 7.
