The dust-proof slide 22 always covers the movable hole 212 of the support rod to prevent metal debris generated by processing from entering the fixed frame 11 and affecting the operation of the rod group control device 12. At the same time, as the lifting clamp rod 17 rotates, the lifting clamp rod 17 will drive the rotating plate 23 to rotate in the rotating plate groove 221. As the lifting clamp rod 17 moves up and down, the inclined slot support rod 172 of the lifting clamp rod 17 will slide in the square hole 231 of the rotating plate 23.

[0051] When the slide motor 32 is started, the slide motor 32 drives the motor screw 321 to rotate, the motor screw 321 drives the screw connecting seat 311 to move, and the screw connecting seat 311 drives the milling slide 31 to slide on the slide track 211, and then the milling slide 31 drives the milling cutter assembly 33 to the milling area of ​​the part, thereby achieving the technical effect of controlling the initial working position of the milling cutter assembly 33 according to the size of the part to be processed.
