[0026] In this embodiment, the guide assembly 2 includes a guide seat 201 and a transmission belt 206. A guide roller 202 is rotatably installed on the side wall of the guide seat 201 close to the flexible welding rod 101. A magnetic sleeve is sleeved on the guide roller 202. The guide roller 202 is magnetically connected to the first support plate 102 through the magnetic sleeve. A motor 204 is fixedly installed inside the guide seat 201.
