Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention belong to the protection scope of the present invention.

[0026] Such as Figure 1-4 As shown, a bidirectionally rotatable pipe wrench according to an embodiment of the present invention includes a vertically arranged pipe body 5, and a tubular upper stopper 1 is fixedly connected to the top end of the pipe body 5. The axis of the stopper 1 is set horizontally, and the dowel rod 4 is sleeved inside the tube body 5, and the dowel rod 4 extends upward into the upper stopper 1 and is arranged on the upper stopper 1 so as to be slidable up and down. Th...

Abstract

The invention discloses a pipe wrench capable of bidirectionally rotating. The pipe wrench comprises a vertically arranged pipe body, wherein the top end of the pipe body is fixedly connected with a tubular upper retainer; the axis of the upper retainer is horizontally arranged; a dowel steel is arranged in the pipe body in a sleeving mode; the dowel steel extends upwards into the upper retainer and is fixedly connected with a lower retainer arranged in the upper retainer in a vertically slidable mode; the upper retainer and the lower retainer are each provided with a meshing surface correspondingly; the meshing surface of the upper stop retainer is opposite to the meshing surface of the lower retainer; the upper part of the pipe body is in threaded connection with a stop screw capable ofextending into the pipe body at least partially; and the stop screw corresponds to the dowel steel. The pipe wrench has the beneficial effects that each meshing surface is an arc surface, and has a large contact area with a steel bar and a large meshing force; the pipe wrench is capable of rotating in two directions as well as continuously rotating; and moreover, the pipe wrench is simple and haswider application prospect.

Description

technical field [0001] The invention relates to the technical field of pipe wrench, in particular to a bidirectionally rotatable pipe wrench. Background technique [0002] With the rapid development of my country's infrastructure construction, reinforced concrete projects are increasing day by day. The mechanical connection of steel bars is an important factor affecting the progress of steel bar projects. Fast and firm mechanical connections will be of great significance for speeding up the progress of steel bar projects and improving the quality of projects. [0003] The pipe wrench used in the mechanical connection of conventional steel bars is inconvenient to realize the continuous rotation of the steel bars. It is inconvenient to bite the steel bars and disassemble them. There has been damage to the active lever lip. [0004] Aiming at the problems in the related technologies, no effective solution has been proposed yet. Contents of the invention [0005] In view of ...
