[0002] PE pipe refers to the pipe material made of polyethylene (Polyethylene). It is a common plastic material and is widely used in various fields; PE has good chemical stability and strong resistance to most acids, alkalis and salt solutions, so it is not easy to be corroded; PE pipe trepanning refers to punching on the polyethylene (PE) pipe to meet the specific needs of an operation. This process is usually used in agricultural irrigation, municipal engineering, drainage system, gas transportation or other pipeline applications.

[0003] The conventional PE pipe fittings are usually held by hand and punched by a handheld electric puncher during punching operation. Although the PE pipe fittings with large diameters are easy to hold and complete the punching operation, the pipe fittings of most common types are difficult to hold, and manual operation is prone to cause the inclination or movement of the PE pipe, thereby affecting the position accuracy of the trepanning. Such errors will directly affect the installation quality of subsequent components (such as drippers, valves, etc.), and if the PE pipe is not firmly fixed, it may slip during drilling due to vibration or excessive force, which not only increases the risk of injury, but also may damage the pipe fittings. Therefore, the PE pipe trepanning device is proposed to solve the above problems. SUMMARY
