[0024] One shaft 2 is connected to the output end of the drive motor 1.

[0025] Shaft 2, shaft 10, shaft 13, shaft 17, and shaft 20 are sequentially driven by gears.

[0026] It should be noted that several different gears are installed on shaft 2, shaft 10, shaft 13, shaft 17, and shaft 20 to achieve function switching.

[0027] A first gear 3 and a second gear 6 are mounted on shaft 2.

[0028] The three-axis 13 is equipped with a first gear 11, a clutch 12, and a second gear 14. The second gear 14 meshes with the second gear 7.

[0029] It should be noted that the second shaft 10 can drive the third shaft second gear 14 through the second shaft second gear 7, and then drive the third shaft 13.

[0030] The four-axis 17 is equipped with a first gear 15, a clutch 16, a third gear 18, and a second gear 19. The second gear 19 meshes with the first gear 11, and the third gear 18 meshes with the second gear 14.

[0031] It should be noted that the three-axis 13 can drive the four-axis third gear 18 through the three-axis second gear 14, which in turn drives the four-axis 17.
