Quick pipe wrench

Abstract

The invention discloses a quick pipe wrench which comprises a wrench handle body, a movable jaw and a fixed jaw, a front-back through rectangular long groove used for installing the movable jaw is formed in the upper half part of the front end of the wrench handle body, an adjusting strip body is arranged at the tail end of the movable jaw, the adjusting strip body is inserted into the rectangularlong groove, the fixed jaw is arranged at the lower half part of the front end of the wrench handle body, the fixed jaw is corresponding to the head part of the front end of the movable jaw, lower stop teeth are arranged on the lower end surface of the adjusting strip body of the movable jaw, a small stop block is arranged on the upper end face of the wrench handle body, upper stop teeth are arranged on the upper end face of the small stop block, the lower stop teeth of the adjusting strip body are correspondingly meshed with the upper stop teeth of the small stop block, an upper round hole is formed in the inner wall of the top of the rectangular long groove, a spring pin is arranged in the upper round hole, and the lower end of the spring pin abuts against the upper end surface of the adjusting strip body. The quick pipe wrench has the function of quickly adjusting the opening, the function of continuously and rapidly repeating the ratchet screwing on pipe fittings with different diameters can be realized, and the working efficiency of an operator are greatly improved.

Description

technical field [0001] The invention relates to the technical field of manual hardware tools, in particular to a quick pipe wrench. Background technique [0002] At present, the common way to adjust the opening of ordinary pipe wrench on the market is to rotate the adjusting nut, and the movable jaw is moved back and forth through the transmission link of the trapezoidal thread, so as to achieve the purpose of adjusting the opening. However, due to the small lead of the trapezoidal thread, it often needs to be rotated several times to achieve the proper size when adjusting the opening. Like 36-inch and 48-inch large-scale pipe wrench, it needs to be rotated to adjust the opening from 0 to more than 100 mm. It takes dozens of turns of the nut to realize it. Such an operation is not only troublesome, but also time-consuming and labor-intensive. It takes a lot of effort for the operator to adjust just one opening, which brings great limitations to actual production operations. ...
