The connecting sleeve (233) is moved down and pressed against the surface of the power pipe by the elastic force of the second spring (234) to assist in limiting the power pipe.

7. The method of using the power pipe cutting device according to claim 6, characterized in that, It also includes the following steps: S3. By rotating the threaded rod (42), the positioning block (44) can be slid on the surface of the operating table (1). By observing the scale (46), the positioning block (44) is moved to the corresponding designated position. Then, one end of the power tube placed on the first placement seat (215) and the second placement seat (231) contacts the side of the positioning block (44) and performs quantitative operation on the power tube. S4. Start the cutting device (228) to make the cutting blade on the cutting device (228) rotate. Then, start the electric push rod (227) to make the cutting device (228) move down. Then start the motor (223) to drive the bidirectional threaded rod (222) to rotate. Then, the first internal threaded sleeve (224) can move on the surface of the bidirectional threaded rod (222) and drive the cutting device (228) to move to cut the power pipe below the U-shaped fixing frame (221). S5. The mounting side plates (36) on both sides of the U-shaped fixing frame (221) can shield the debris generated by the cutting equipment (228) cutting the power pipe, and then the debris can fall into the collection bin (31) through the opening (34) for centralized storage. S6. After the cutting is completed, the cut power pipe can be pulled towards the side of the positioning block (44). Then the positioning block (44) and the second internal threaded sleeve (43) are fixedly connected. As the power pipe moves, the positioning block (44) can release the fixing of one end of the power pipe. Then the power pipe can be pulled out.
