The plurality of connecting rods 1.3 are connected in series at the four corners and the middle of the long sides of the front plate 1.1 and the rear plate 1.2 to fixedly connect the front plate 1.1 and the rear plate 1.2 into a whole.
[0023] The driving shaft 2 and the driven shaft 3 are rotatably mounted parallel to each other and transversely on the front and rear panels 1.1, 1.2, with their front ends protruding from the front of the front panel 1.1. The front ends of both the driving shaft 2 and the driven shaft 3 are provided with externally threaded joints 10. The front portion of the driving shaft 2 is rotatably mounted within a shaft hole provided in the front panel 1.1 via a bearing 9. The driven shaft 3 is rotatably mounted within corresponding shaft holes provided in the front and rear panels 1.1, 1.2, via a bearing 9.

The driving gear disc 4 is sleeved and fixed on the driving shaft 2, and the driven gear disc 5 is sleeved and fixed on the driven shaft 3 and meshes with the driving gear disc 4.
[0025] The driving motor 6 is located directly behind the driving shaft 2 and is fixedly mounted on the outer surface of the rear machine plate 1.2. The rear end of the driving shaft 2 is sleeved and fixed on the output shaft of the driving motor 6.
[0026] A limit rod 7 is provided upright on the surface of the driven sprocket 5. A corresponding limit block 8 is provided on the inner surface of the rear plate 1.2 to block the circumferential movement of the limit rod 7, thereby enabling the drive motor 6 to output in both forward and reverse directions. To this end, the limit block 8 must be located along the circumferential trajectory of the limit rod 7. Of course, the installation positions of the limit rod 7 and the limit block 8 are not limited to the above.
