Telescopic force-applying pipe wrench

Abstract

The invention discloses a telescopic force-applying pipe wrench. The telescopic force-applying pipe wrench comprises a fixed wrench body, a movable wrench body, a wrench handle and a force-applying pipe, wherein the movable wrench body is installed on the front end of the fixed wrench body, the wrench handle is arranged on the back end of the fixed wrench body, the force-applying pipe is additionally installed on the tail end of the wrench handle, the L-shaped movable wrench body is installed above the fixed wrench body, a fixed jaw is arranged on the front end of the fixed wrench body, sunken arc surfaces are formed on the outside end surfaces of the fixed jaw, sawtooth grains are formed on the arc surfaces, and another fixed jaw is arranged on one end surface, which is opposite to the front end surface of the fixed wrench body, of the movable wrench body. According to the telescopic force-applying pipe wrench, the fixed jaws are arranged on the opposite surfaces of the fixed wrench body and the movable wrench body, the sunken arc surfaces are formed on the outside end surfaces of the fixed jaws, and the sawtooth grains are formed on the arc surfaces, so that the two fixed jaws can be preferably fixed to the outer side wall of the pipe after the two fixed jaws relatively move to approach, and slipping is avoided.

Description

technical field [0001] The invention relates to the technical field of hardware tools, in particular to a telescopic force-added pipe wrench. Background technique [0002] The telescopic pipe wrench is widely used in installation and construction, and the telescopic afterburner pipe wrench can adapt to the disassembly and assembly of threads of various shapes, and is small in size and light in weight. One end of the pipe wrench needs to be fixed on the outside of the pipe, but the contact surface between the jaws and the pipe tends to slip during use, resulting in unstable fixation. Once slippage occurs, it will affect the work efficiency, and the jaws of the pipe wrench will scratch the outer surface of the pipe, which will affect the quality of the product. How to effectively ensure the firm contact between the pipe wrench and the pipe is a problem that needs to be considered and solved at present.
