Abstract

The utility model discloses a quick universal pipe wrench, comprising a handle (1), a pin roll (2), a torsion spring (3), a wrench head (4), a fixed jaw (5) and an elastic pin (6). When in use, the handle is held by one hand, when the wrench head (4) touches the workpiece (7), the workpiece (7) is clamped tightly via the wrench head (4) together with the fixed jaw (5) under the action of the elasticity of the torsion spring (3), and then is clamped tightly and is rotated through clockwise rotating the handle (1) forcibly, and then is loosened through rotating the handle (1) counterclockwise; the movements are similar with the ratchet wheel mechanism. The utility model has the advantages of realization of quick and continuous operation without turning any wormgear or adjusting nut, fast adjustment of the opening and closing of the jaw, single hand ratchet screw operation, reliable function, ability of clamping round pipe, square pipe or profiled workpiece, and convenient use.

Description

Quick omnipotent pipe vice

One. affiliated technical field

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

Two. background technology

Pipe vice is a kind of pipe running tool commonly used, and its function singleness only is used for the circular pipe of clamping.Pipe vice in the market mainly is made up of binding clip, fixed teeth piece, handle and adjusting nut.Must twist adjusting nut earlier according to pipe diameter during use and regulate openings of sizes, live binding clip with a hand then, use another hand turning handle, thereby finish the process of clamping pipe.This complicated operating process, efficient are low, inconvenient.

Adjustable wrench also is a kind of hardware ﹠ tools of using always, and it is a kind of common tool of twisting hex nut or square cross.Must make to pull and mouthful open, satisfy interlock work by twisting worm gear during operation, the operation of this instrument still efficient be low, inconvenient, and the shape of workpiece is had strict restriction.

Three. the utility model content

The technical scheme that its technical problem that solves the utility model adopts is: need not twist any worm gear or adjusting nut, opening fast with interlock of pipe vice of realization operated; The function that integrates traditional pipe vice and adjustable wrench can not only clamping round piece and energy clamping square or special-shaped workpiece.

For solving the problems of the technologies described above, quick omnipotent pipe vice of the present utility model is made up of binding clip, fixed teeth piece and handle.Connect with the intermittence bearing pin between binding clip and the handle, binding clip can be rotated around bearing pin, between binding clip and bearing pin, added a torsion spring structure, similar ratchet mechanism, make it in the course of the work, not only can regulate openings of sizes automatically, and reinforcing is revolved tighter and tighter clockwise according to the workpiece size, inhour unscrews, and has realized pulling continuously fast and regulating automatically of operation.The fixed teeth piece is fixed on the handle with resilient key, and the profile of tooth of fixed teeth piece and binding clip is an arc, is different from the straight-tooth shape of traditional pipe vice, thus can clamping circle, square or special-shaped workpiece.

After having adopted such structure, make operation become quite easy and convenient, only hold handle and just can finish the work of repeatedly twisting workpiece rapidly with one.

Four. description of drawings

Fig. 1 is the quick omnipotent pipe vice structural representation of the utility model.

Five. the specific embodiment:

Quick omnipotent pipe vice shown in Figure 1 is made up of handle 1, bearing pin 2, torsion spring 3, binding clip 4, fixed teeth piece 5 and resilient key 6.Handle 1 is connected with binding clip 4 usefulness bearing pins 2, and binding clip 4 can rotate around bearing pin 2; Torsion spring 3 is enclosed within on bearing pin 2 and the binding clip 4; Fixed teeth piece 5 usefulness resilient keys 6 are fixed on the handle 1.

Fig. 1 also is the working state schematic representation of the quick omnipotent pipe vice of the utility model.Hold handle 1 with one, when binding clip 4 was run into workpiece 7, binding clip 4 can be under the effect of torsion spring 3 elastic force, and with regular jaw 5 clamping work pieces, the handle 1 that firmly turns clockwise again can clamping work pieces and realize turning of work piece.When being rotated counterclockwise handle 1, can loosen workpiece again, similar ratchet mechanism action has realized quick continued operation fully.Under the elastic force effect of torsion spring 3, binding clip 4 can be regulated its openings of sizes according to different sizes, difform workpiece automatically.

The quick omnipotent pipe vice of the utility model is compared with existing pipe pipe vice, after binding clip 4 changed present rotational structure into from existing rectilinear motion, it is about 30% that material cost reduces, and reduced manufacturing procedure, after utilizing the ratchet mechanism of torsion spring 3, integrated cost also descends.

In sum, the advantage of the utility model rapid universal grip wrench is: structural design is namely simply again skilful Wonderful, need not twist any worm gear or adjusting nut, realized opening fast continuously and the interlock worker of pipe vice Do, reliable in function can be pressed from both sides pipe and can be clamped square tube or special-shaped workpiece again, has also reduced product cost, Also be applicable to batch production.

Claims

1. a quick omnipotent pipe vice comprises handle, binding clip and fixed teeth piece, and the fixed teeth piece is fixed on an end of handle, and it is characterized in that: binding clip is hinged on handle end by bearing pin, and torsion spring set is on pivot pin, and the two ends of torsion spring are overlapped on binding clip and the handle.
