The design of the rotation mechanism 23 fully considers ease of operation and efficiency, enabling operators to easily adjust the position of the pipe to meet the needs of complex cutting tasks.

[0034] Combination Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the indexing mechanism 23 includes an indexing motor 231 disposed on the outer wall of the top seat 22. The indexing motor 231 serves as the power source for the indexing mechanism 23 and can ensure the stability and accuracy of the pipeline during rotation.

[0035] The output end of the indexing motor 231 is connected to a turntable 232, which is the direct drive component for pipe rotation. The turntable 232 ensures a tight fit with the pipe. The turntable 232 is adaptable to pipes of different specifications and materials. A sleeve 233 is installed on the outer wall of the turntable 232. The sleeve 233 protects the pipe from scratches and damage. The sleeve 233 can tightly fit the pipe surface, reducing friction and vibration during the cutting process.

[0036] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the main body 1 includes a fixed base 11, and the cutting machine 4 is fixedly installed inside the fixed base 11.
