Abstract

The invention provides a pipe wrench. The pipe wrench is composed of a handle and a wrench head. The wrench head is composed of a movable wrench jaw, a fixed wrench jaw and a sliding structure, wherein the movable wrench jaw is connected with the main body of the wrench head through the sliding structure and matched with the fixed wrench jaw; the handle is arranged on one side of the wrench head and connected with the tail end of the wrench head. The pipe wrench is wide in single twisting range and is particularly applicable to maintenance of laid small-diameter pipes.

Description

[0001] technical field [0002] The invention relates to a hardware tool, in particular to a pipe wrench. Background technique [0003] The existing straight pipe wrench generally has the handle in the middle of the tong head, but when the space around the pipe is small, such a pipe wrench needs to be twisted and repositioned many times to achieve the purpose, which wastes a lot of manpower and time, especially in the Repair some small-diameter pipes such as water pipes, and the pipes have been laid in narrow pipe grooves. When the range of activities of the pipe wrench is small, it is necessary to open the covering around the pipes in a large area during operation, which is likely to cause large damage to the covering. Repair The cost is high, and the jaws are constantly adjusted at the same time, which wastes time, because the space is small, and workers are also prone to injury. Contents of the invention [0004] Purpose of the invention: In view of the above problems,...
