Abstract

The utility model belongs to the technical field of installation and maintenance tools for pipes, in particular to a multi-purpose pipe wrench. The multi-purpose pipe wrench is characterized in that the wrench is composed of a wrench head, a wrench toothed head, a wrench handle, a wrench pole and a force-applying handle. The wrench head is provided with movable teeth, the wrench toothed head is arranged at the upper portion of the wrench head, the wrench handle is fixedly inserted in the wrench head, the lower portion of the force-applying handle is provided with a screw meshing head, the force-applying handle is fixedly installed at the wrench toothed head, and the wrench pole is an auxiliary component which can be inserted in a fixing hole of the wrench head during usage. The pipe wrench has the function of dismounting and connecting pipe pieces, also has the effect of wire drawing and pipe dismounting without depending on a table vice or a pressure jaw, and thereby has the advantages of multiple functions, fine fixation, small volume, light weight, convenient carrying, simple operation and the like.

Description

The multipurpose pipe wrench

One. technical field:

The utility model belongs to pipeline installation, maintenance technical field of tools, particularly a kind of pipe wrench that serves many purposes.

Two. background technology:

The design people finds that in long-term work in the installation of every pipeline and the maintenance, we can use common several pipeline installation and maintenance instruments, as pipe vice, also claim pipe wrench, fixed pressure clamp, trigonometric expression pressure clamp, hot candied instrument etc.Present pipe wrench can only dismounting, connecting tube, and it does not have other purposes again, and defective is that function is few, can not solve to rely on the work that bench vice or pressure clamp remove to finish wire drawing or dismounting pipeline.

Three. summary of the invention:

The purpose of this utility model is to design a kind of novel multifunctional pipe wrench at existing pipe wrench above shortcomings.It is many that it has function, and stationarity is good, and volume is little, and is in light weight, easy to carry, simple operation and other advantages.

The feature of this multipurpose pipe wrench is that it is made up of pipe wrench head, tong key head, pipe wrench handle, pipe wrench hack lever, afterburning handle five parts, the pipe wrench head is provided with movable tooth, the tong key head is located at pipe wrench head top, tong key head bottom is provided with the positioning nut, the pipe wrench handle is inserted in the pipe wrench head and is solidified as a whole, and the bottom of afterburning handle is provided with screw mandrel and stings a head, and afterburning handle is packed on the tong key head, the pipe wrench hack lever is an auxiliary, and it is inserted in the fixing hole of pipe wrench head in the use.The positioning nut of pipe wrench head, tong key head and bottom, pipe wrench handle three parts then can be formed existing pipe wrench, adjust the positioning nut of tong key head bottom in the use, just can make the tong key head block that pipe is dismantled and pipe laying.Pipe wrench handle and being connected and fixed of pipe wrench head can be adopted and be threaded or screw is connected, and are convenient to dismounting like this.Movable tooth on the pipe wrench head, it is provided with for ease of the pipeline that blocks different size, and movable tooth is the tusk that can magnify or dwindle.Core of the present utility model is to be provided with afterburning handle and screw mandrel is stung a head on the tong key head, afterburning handle is the same like the afterburning handle on the bench vice, just can be when it is rotated down with the pipe fitting chucking of bottom, design when screw mandrel is stung the silk head for the pipe fitting wire drawing, pipe fitting is bitten the back rotary tube piece just can be hot candied, just pipe fitting unclamped when afterburning handle rotates up.Can be hot candied on pipe wrench of the present utility model, it increases major function exactly newly.The pipe wrench hack lever is to block the non-oscillatory annex of pipe wrench head during for wire drawing, and the pipe wrench hack lever is inserted in the pipe wrench head fixing hole in the use, tramp with one's feet pipe wrench head and pipe wrench hack lever, and the pipe wrench head just can not swung when hot candied.

Advantages such as pipe wrench of the present utility model has multipurpose, and stationarity is good, and volume is little, and is in light weight, simple to operate, easy to carry.
