[0069] A bevel gear 7 is mounted on the second rotating shaft 6;

[0070] a cylindrical spur gear 8, which is mounted on the first rotating shaft 3 and meshed with the bevel gear 7;

[0071] A connecting slider 9, wherein the connecting slider 9 is slidably connected to the fixing plate 2;

[0072] The telescopic drive mechanism 100 is installed at the end of the connecting slider 9 away from the second rotating shaft 6;

[0073] The positioning transmission mechanism 200 is arranged on the second rotating shaft 6 and cooperates with the output end of the grinder. The positioning transmission mechanism 200 is connected to the other end of the connecting slider 9.

[0074] In an embodiment of the present invention, when in use, the grinder moves toward the plastic component, and the grinder drives the mounting plate 1 and the fixed plate 2 to move, and the fixed plate 2 drives the connecting slider 9 and the telescopic drive mechanism 100 to move. The telescopic drive mechanism 100 first contacts the plastic component and contracts by limiting it. The telescopic drive mechanism 100 thereby drives the connecting slider 9 to slide along the fixed plate 2, and the connecting slider 9 drives the positioning transmission mechanism 200 to move. The positioning transmission mechanism 200 thereby achieves a positioning connection with the output end of the grinder, thereby achieving synchronous rotation of the second rotating shaft 6 with the output end of the grinder.
