Abstract
The utility model discloses a self-clamping adjustable alligator wrench. The self-clamping adjustable alligator wrench overcomes the defects that the traditional wrench has slow clamping speed, and the work efficiency is low. The utility model comprises a jaw, a movable jaw, a handle, a position pin, an adjustable position pin, etc., wherein, the movable jaw can slip relatively on the jaw, the handle is respectively hinged with the jaw and the movable jaw, and a crank block self-clamping mechanism is formed. Simultaneously, an adjustable hole groove is arranged at the rear part of the jaw, and the opening width of the two jaws is adjusted by adjusting the position pin. The utility model has the advantages that the working process of clamp and screw are completed in one step. The utility model has the advantages that the clamping speed is high, the structure is simple, the operation is convenient, and the self-clamping adjustable alligator wrench is suitable for different specification work pieces.
Description
The utility model relates to a kind of pipe wrench adjustable wrench.
Traditional pipe wrench and spanner are adjusted jaw by the rotation worm gear and are clamped or unclamp workpiece.Need clamp turning of work piece more earlier during work, clamp speeds is slow, inefficiency, and behaviour does inconvenience.
The purpose of this utility model is that to overcome above-mentioned prior art not enough and provide a kind of fast from clamping Pipe-tongs adjustable spanner.
Technical solution of the present utility model is: as shown in Figure 1 and Figure 2.By jaw 1, moving jaw 2, handle 3, alignment pin 4, adjustable whole alignment pin 5 compositions such as grade.Wherein moving jaw 2 can slide relatively with jaw 1, to change distance between two jaws.Handle 3 is installed on the jaw 1, and handle 3 is hinged with jaw 1 and moving jaw 2 respectively.Jaw 1 and handle 3 constitute revolute pair A by adjustable whole alignment pin 5, and moving jaw 2 and handle 3 constitute revolute pair B by alignment pin 4, and jaw 1 and moving jaw 2 constitute sliding pair C.Jaw 1, moving jaw 2 constitute crank block from clamp mechanism with handle 3.Simultaneously, have the adjustment hole slot, to be suitable for the workpiece of different size at the rear portion of jaw 1.
Operation principle of the present utility model is: constituted slider-crank mechanism by jaw 1 and moving jaw 2 and handle 3.Its pivot is A, and crank is AB, and connecting rod is BC, and slide block is C.During work, the swing handle 3 that makes progress, by the effect of crank connecting link, two jaws open, and after the alignment pieces, are rotated down handle 3, two jaws nature clamping work pieces, continue to rotate handle, and then workpiece is twisted.If the specification difference of workpiece can be adjusted by the adjustment hole slot at jaw 1 rear portion.
Description of drawings:
Fig. 1 is the utility model sleeve type pipe tongs wrench structural representation.
Fig. 2 is the utility model chute-type Pincers with spanner function structural representation.
Good effect of the present utility model is: clamp, screw one the step finish, swing handle process self-tightening, backhaul from the pine, applicable to different size, difform workpiece. Simultaneously simple in structure than the conventional tube Pincers with spanner function, and easy to use.
