Embodiment Construction

[0018] The fast clamping pipe fitting method of the present invention realizes locking or releasing the jaws by pressing down or lifting the pliers handle hinged with the pliers cover, and realizes the size adjustment of the jaws through the relative sliding of the pliers cover and the handle section of the L-shaped pliers head; The above-mentioned locking jaw is that the pincer handle that presses down presses the locating pin that restricts the limit row of teeth at the end to the locating row of teeth that are formed on the handle section of the L-shaped pliers head, and makes the limit row of the locating pin align with the L-shaped The positioning row teeth of the handle section of the pliers are meshed, and the release jaw is to lift the pliers handle away from the positioning pin, and the positioning pin is kept away from the handle section of the L-shaped pliers under the action of the support spring, and makes the limit row of the positioning pin The teeth are separate...

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 fitting method and a 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 purpose of the present invention is to overcome the above-mentioned defects of the prior art, and to provide a fast and reliable pipe clamping method capable of quickly and reliably clamping and releasing the pipe. 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 fitting method of the present invention realizes locking or releasing the jaws by pressing down or lifting the pliers handle which is hinged wit...
