Problems solved by technology

[0002] Pipe wrench is a hardware tool used for installation and removal of pipes. The commonly used open pipe wrench operates pipes with different diameters by manually adjusting the size of the opening. The construction is not flexible enough, especially for large-diameter and special-shaped cylindrical bodies. Unable to construct, causing difficulty in construction

Embodiment Construction

[0030] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0031] The pipe wrench of the present embodiment is not limited by the diameter and length of the cylindrical body shape (cylindrical body can be polygonal or irregular) of the work done, such as figure 1 and figure 2 As shown, the pipe wrench in this embodiment is composed of two arc-shaped pipe wrench A and B. When the two arc-shaped pipe wrench forms a complete pipe wrench, it includes a circular base 1, four claws 2, two A sliding booster rod 3, a cover plate 4, six bolts 5, six metal sleeves 6 and six cross-recessed countersunk screws 7. In other embodiments, the number of parts such as the claw 2 , the sliding force bar 3 , the bolt 5 , the metal sleeve 6 and the cross-recessed countersunk screw 7 can be increased according to actual needs. Among them, the annular base 1 is used to fix and guide the jaws 2. It is assembled from two detachable...

Abstract

The invention relates to hardware tools, in particular to pipe tongs and a using method thereof. The pipe tongs are not limited by the shape, the diameter and the length of an acted cylinder; The pipe tongs comprise bases, clamping jaw assemblies and sliding stress application rod assemblies; the clamping jaw assemblies are fixed to the bases and pushed along the inner sides of clamping jaws through sliding stress application rods, so that the clamping jaws contract, and a pipe is clamped; and rotary acting on the pipe is achieved. The pipe tongs are simple in structure and convenient to operate, and construction operation can be conducted on any cylindrical body.

Description

technical field [0001] The invention relates to a hardware tool, in particular a pipe wrench which is not restricted by the shape, diameter and length of a cylindrical body. Background technique [0002] Pipe wrench is a hardware tool used for installation and removal of pipes. Commonly used open pipe wrench operates pipes with different diameters by manually adjusting the size of the opening. The construction is not flexible enough, especially for large-diameter and special-shaped cylindrical bodies. Unable to construct, causing construction difficulties. Contents of the invention [0003] The purpose of the present invention is to provide a pipe wrench that is not limited by the shape, diameter and length of the cylindrical body, and a closed ring is formed by two detachable semicircular bases with claws and sliding force bars , the operation is not limited by the shape, diameter and length of the cylindrical body. [0004] In order to achieve the above object, the tec...
