[0061] Preferably, the handle 1 and the transverse rod 6 are both PE pipes.

[0062] In order to better illustrate the technical effect of the utility model, the following specific embodiment is provided to illustrate the above technical process.

[0063] Example 1: A pipe cutting device for the inner side of a PE pipe specifically designed for the construction of underground ground source heat pump pipes, such as... Figure 1 As shown, it includes a handle 1, a crossbar 6, a main body rod 2, a cutting blade 4, a rotating component 3, and a lifting rope 5.

[0064] Handle 1 uses PE tubing for operator grip, providing ease of operation.

[0065] The crossbar 6 is made of PE pipe and is oriented in a cross direction with the handle 1. It is used to lock onto the pipe opening to fix the cutting position.

[0066] The main rod 2 uses PE pipes, and the length is selected on-site based on actual needs and the location is cut accordingly.

[0067] The cutting blade 4 is made of high-strength material and has a sharp cutting edge, enabling it to cut buried pipes quickly and accurately.

[0068] The lifting rope 5 adjusts the position of the cutting blade 4 so that after the vertically inserted blade reaches the cutting point, the cutting blade 4 can maintain an ideal cutting angle with the cutting surface.

[0069] The rotating part 3 is used to fix the cutting blade 4 and ensure the stability of the position of the cutting blade 4 during the cutting process. The rotating part 3 is a universal head, with one end threaded to the main body rod 2 and the other end welded to the cutting blade 4. The side is punched to pass through the lifting rope 5. The maximum rotation angle of the rotating part 3 is 90 degrees, which means it can rotate from a vertical state to a horizontal state at most.

[0070] The method of using the pipe cutting device of this utility model is as follows:

[0071] 1. First, determine the cutting position. By selecting a tool with a suitable length of main body rod 2 (if the main body rod 2 is made of PE material, the size can be determined and made on site), after the cutting blade 4 is lowered to the cutting position, the crossbar 6 below the handle 1 presses down on the pipe opening to ensure that the cutting head of the cutting blade 4 is in the cutting position when the pipe is rotated and cut.

[0072] 2. Then, tighten the lifting rope 5 so that the cutting blade 4 is perpendicular to the material being cut, and secure the lifting rope 5 to the blade crossbar 6 to ensure the blade is in the correct position.

[0073] 3. The operator holds handle 1 and rotates it forcefully to make the cutting blade 4 contact the buried pipe and cut it.

[0074] 4. During the cutting process, maintain a stable force and speed to ensure the accuracy and quality of the cut.

[0075] 5. During cutting, the lifting rope 5 can be untied to fine-tune the position of the cutting blade 4.

[0076] 6. After cutting is complete, release the pull cord 5 and remove the tool.

[0077] The above merely illustrates the specific implementation of the present application, but the protection scope of the present application is not limited to this. Any change or replacement within the technical scope disclosed by the present application should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
