[0002] Hydraulic pipelines are an important part of hydraulic systems. There are many types of pipelines used in hydraulic systems. Depending on the working pressure and installation location of the hydraulic system, steel pipes, copper pipes, rubber pipes, nylon pipes and plastic pipes are selected. Once these pipelines are damaged and leak, it will pollute the environment and affect the normal function of the system, or even endanger safety.

[0003] During the assembly process of the hydraulic system, it is necessary to cut hard pipes such as steel pipes, copper pipes, etc. that are too long.

[0004] After searching, the patent with announcement number CN214136144U discloses a pipe cutter, whose adjusting member can drive the second bracket to move through the first bracket, so as to adjust the position relationship between the first support roller, the second support roller and the cutting member. No matter the diameter of the pipe is large or small, the first support roller, the second support roller and the cutting member can achieve stable three-point positioning, which is convenient for subsequent staff to cut the pipe.

[0005] Although the above scheme can realize the cutting of the pipe, after rotating the shell around the pipe to be cut for one or several weeks, the knob needs to be turned to push the disc blade so that the disc blade gradually cuts into the pipe to cut the pipe. This is more troublesome to use and needs to be improved. Utility Model Content
