A kind of water pipe maintenance cut-off tool

Abstract

The invention relates to a cutting tool, in particular to a water pipe maintenance cutoff tool. The technical problem to be solved is how to provide a water pipe maintenance cutoff tool with a markingfunction and capable of preventing water from splashing on maintenance personnel. The water pipe maintenance cutoff tool comprises an upper arm, a lower arm, a first spring, a cutoff component, a marking component and the like; the left part of the upper arm is rotatably connected with the left part of the lower arm, the lower arm is arranged on the outer side of the upper arm, the first spring is connected between the left part of the upper arm and the left part of the lower arm, and the left part of the upper arm and the left part of the lower arm are provided with the cutoff component forcutting off water pipes in a rotating mode. The marking component is arranged, the cut position can be marked through the marking component, so that the device has a marking function, the practicability of the device is improved, meanwhile, water pipes can be more accurately cut off, the cutting device can cut off the water pipes in a quite labor-saving manner, and because a reset gear is smallerthan an arc-shaped rack, a blade can be reset in a more labor-saving manner.

Description

technical field [0001] The invention relates to a cutting tool, in particular to a cutting tool for water pipe maintenance. Background technique [0002] Water pipes are water supply pipes. Modern decoration water pipes are built with buried walls. There are three types of water pipes. The first type is metal pipes, such as hot-dip cast iron pipes with plastic lining, copper pipes, and stainless steel pipes. The second category is plastic composite metal pipes, such as plastic composite steel pipes, aluminum-plastic composite pipes, etc. The third category is plastic pipes, such as PB, PP-R, etc. Water pipe maintenance needs to cut off the broken part of the water pipe, which can save materials and save maintenance time. [0003] Now when cutting the damaged water pipe, the maintenance personnel use the water pipe cutter to cut it off. Before cutting the water pipe, it is necessary to mark the cut-off place, which can improve the accuracy of the water pipe cutting. Now it ...
