[0027] Example 3

[0028] like Figure 1-3 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the surface of the middle part of the output shaft 31 is slidably connected with the adjusting gear 32, the surface of one end of the output shaft 31 is rotatably connected with the fifth gear 33, a groove is provided on the side of the fifth gear 33 close to the adjusting gear 32, the shape of the groove provided by the fifth gear 33 is the same as the cross-section of the adjusting gear 32, the surface of the fifth gear 33 meshes with the surface of the third gear 25, a convex block is provided in the middle of the adjusting gear 32, a sixth gear 34 is rotatably connected with the surface of the end of the output shaft 31 away from the fifth gear 33, a groove is provided on the side of the sixth gear 34 close to the adjusting gear 32, the shape of the groove provided on the surface of the sixth gear 34 is the same as the shape of the groove provided on the surface of the fifth gear 33, the surface of the sixth gear 34 meshes with the surface of the fourth gear 26, a mounting block 35 is fixedly connected to the bottom of the inner cavity of the gear box 12, the top of the mounting block 35 is bolted to the limiting block 36, the top of the limiting block 36 overlaps with the surface of the adjusting gear 32, and the diameter of the sixth gear 34 is larger than the diameter of the fifth gear 33.
