Rapid pipe fitting clamping method and pipe wrench

Abstract

The invention relates to a rapid pipe fitting clamping method and a pipe wrench and solves the problem that the existing pipe wrench is slow in clamping. The method is that a wrench handle hinged with a wrench sleeve is pressed or lifted to achieve jaw locking and release, and adjustment of jaw size is achieved through relative sliding of the wrench sleeve and a handle section of an L-shaped wrench head. The pipe wrench is that the L-shaped wrench head is connected with the wrench handle through the wrench sleeve, the upper portion of the wrench sleeve is hinged with the wrench sleeve in a sleeved mode, the lower portion of the wrench sleeve is in transversely sliding fit in a sleeved mode, a jaw tooth row is manufactured on the inside of the head section of the L-shaped wrench head, a location tooth row is manufactured on the inside of the handle section, and an end face jaw tooth row is manufactured at the front end of the wrench handle. A locating pin supported by a spring is assembled on the wrench sleeve, a limiting tooth row matched with the location tooth row on the handle section of the wrench head is manufactured at the front end of the locating pin, the locating pin presses towards the wrench handle on the front portion of a hinged shaft under supporting of the spring, and the locating pin presses towards the location tooth row on the handle section of the wrench head under extrusion of the wrench handle on the front portion of the hinged shaft. The rapid pipe fitting clamping method and the pipe wrench can rapidly and reliably clamp and release pipe fittings, and have the advantages of being convenient to use, rapid and reliable in operation and capable of obviously improving operation efficiency.

Description

technical field [0001] The invention relates to a pipe wrench, in particular to a quick clamping pipe wrench method and the pipe wrench. Background technique [0002] Existing pipe wrench has various varieties and different forms, but according to the inventor's long-term research, it is found that: the existing pipe wrench still has the defect of being unable to quickly and reliably clamp and release pipe fittings. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned defects of the prior art, and provide a quick clamping pipe wrench method capable of quickly and reliably clamping and releasing the pipe fittings. The purpose of the present invention is also to provide a pipe wrench for implementing the method. [0004] In order to achieve the above object, the quick clamping pipe wrench method of the present invention locks or releases the jaws by pressing down or lifting the handle hinged with the pliers cover, and real...
