Abstract
The utility model relates to a spanner, particularly a tube spanner which is usually called pipe wrench. The utility model is composed of a movable wrench block (1), a locating shaft (2), a wrench body (3) and a spring (4). The fixed wrench block (5) and the wrench body (3) are integrated. When used, a pipe is clamped in the wrench jaw which is aligning to the pipe and strained by one push slightly. The wrench can work reiteratively by wrenching the wrench body (3) and avoid the pipe wrench of the prior art which adopts the adjustable nut to adjust the wrench jaw size. The utility model has the advantages of high work efficiency, convenience for carrying. The wrench is suitable for working along the wall; the wrench body (3) is molded by steel plate and the weight of the entire wrench is light compared with the existing and same specification pipe wrench.
Description
The utility model relates to a kind of spanner, particularly bulldog wrench: bulldog wrench is pipe vice usually.Pipe vice is used for rotating pipe when being the installation, maintenance small pipeline.Existing pipe vice all is that operating efficiency is lower with the mode size of regulating jaw of rotation adjusting nut, and whole apparatus structure is a yi word pattern, and this is to making troubles along the wall operation, and it adopts casting processing, and weight is very big.
The purpose of this utility model is to need not to regulate in the permission scope of application and can directly use in order to provide a kind of, and structure is
Type, and the spanner, particularly bulldog wrench of the existing same specification product light 1/2 of weight ratio.
Its structure of the utility model as shown in Figure 1.It is made up of active clamp block (1), locating shaft (2), vice body (3) and spring (4).Active clamp block (1) is
Type, the inboard is provided with sawtooth, and an end is fixed on the vice body (3) by locating shaft (2), and is connected with spring (4), and spring (4) can be designed to torsion spring and be fixed on the vice body (3), and an end of vice body (3) is fixed clamp block (5).Under the inoperative situation, active clamp block (1) be subjected to spring (4) power effect and tumble to fixed clamp block (5), this moment be the starting point of the minimum scope of application.In the time will carrying out greater than the operation of starting point sized tube, as long as jaw is aimed at pipe, slightly firmly one push away, pipe snaps in jaw, gets final product the turn pipe, after fulfiling assignment, can take out pipe.This device also is the instrument that screw is killed in starting.
This apparatus structure is simple, and is easy to operate, and is fit to along the wall operation, and its vice body (3) adopts steel plate forming, so the existing same specification pipe vice of weight ratio is light by 1/2.It is fit to, and pipeline is installed, reconditioning work, has certain practical value.
