[0021] The working principle and usage process of the present utility model are as follows: The conduit is sent to the coating and cutting pipe structure 2 through the pipe feeding component 1. After the coating is completed, the pressing cylinder 223 fixes the conduit on the pushing seat 222. The pushing cylinder 221 works to push the conduit onto the pipe cutting seat 232. The clamping fingers 34 clamp the conduit. Then, the pressing cylinder 223 and the pushing cylinder 221 retract. The clamping lifting cylinder 33 moves upward, and the transverse movement is carried out through the transverse moving motor 312. When the conduit reaches a certain length, the pipe cutting cylinder 231 drives the cutter to cut the conduit. The fixed upward pushing cylinder 35 rises to lift and support the pipe.
