[0024] Among them, the transmission assembly includes a rotating wheel 10, which is fixedly installed at both ends of the mounting shaft 11. One side of the rotating wheel 10 is provided with teeth 12, and the side of the rotating wheel 10 away from the teeth 12 is provided with a smooth surface 13. The teeth 12 can engage with the upper tooth plate 8 and the lower tooth plate 9.

[0025] Among them, side mounting plates 20 are fixedly installed at both ends of the upper surface of the rotating plate 17, threaded rods 19 are rotatably installed at both ends of the side mounting plates 20, clamping plates 18 are threadedly connected at both ends of the threaded rod 19, and a transmission member 21 is provided at one end of the threaded rod 19.

[0027] In the utility model, the built-in motor drives the active gear 22 to rotate, and the active gear 22 rotates to drive the driven gear 23 to rotate. The driven gear 23 cooperates with the transmission member 21 to drive the threaded rod 19 to rotate (the threaded rod 19 is a bidirectional threaded rod 19, and the threads at both ends are in opposite directions), thereby driving the clamping plates 18 at both ends of the threaded rod 19 to approach each other, so that the clamping plates 18 fix the plastic part on the upper surface of the rotating plate 17, and the laser processing member 7 pre-processes the surface of the plastic part.
