[0029] As Figure 1 And Figure 4As shown in the embodiment provided by the utility model, the driving assembly 30 comprises a driving motor 31 fixedly connected with the top cover 21 and a gear 32 connected to the output shaft of the driving motor 31, and the driving motor 31 is provided with fixing holes on both sides for fixedly connecting with the top cover 21. The top cover 21 is provided with a fixing column 211 which can be inserted into the fixing holes, and the locking member passes through the fixing holes on the driving motor 31 and is locked in the fixing holes, so that the driving motor 31 is fixedly connected with the top cover 21. By inserting the fixing column 211 on the top cover 21 into the fixing holes of the driving motor 31, the positioning accuracy between the driving motor 31 and the base 10 can be effectively ensured.

[0030] As shown in Figure 1 , Figure 2 and Figure 3 , in addition, by using the locking member such as a bolt, a stud and a pin to pass through the fixing holes on the driving motor 31 and be locked in the fixing column 211, the stability of the fixed connection between the driving motor 31 and the top cover 21 can be effectively ensured, so that the stability of the rotation of the top cover 21 and the cover body 22 relative to the base 10 under the action of the reaction force between the gear 32 and the transmission structure on the base 10 can be ensured. The transmission structure is a gear tooth 11 arranged on the base 10 and engaged with the gear 32 connected to the driving motor 31. By engaging the gear 32 on the output shaft of the driving motor 31 with the gear tooth 11 on the base 10, the stability and smoothness of the rotation of the top cover 21 and the cover body 22 relative to the base 10 driven by the driving motor 31 can be further improved.

The top cover 21 is provided with a fixed boss, and the cover body 22 is provided with a fixed groove. By embedding the fixed boss of the top cover 21 in the fixed groove of the cover body 22, the top cover 21 and the cover body 22 can be clamped and fixed, and the stability of the fixed connection between the top cover 21 and the cover body 22 can be effectively ensured.

In addition, the top cover 21 is provided with a plurality of limiting grooves 12 on the base 10 for the limiting screws 51 to pass through, and the elastic washers 52 abut against the outer edge surface of the limiting grooves 12. Since the diameter of the elastic washer 52 is greater than the width of the limiting groove 12, after the limiting screw 51 passes through the elastic washer 52 and is locked in the mounting column 213, the elastic washer 52 abuts between the nut portion of the limiting screw 51 and the outer edge surface of the limiting groove 12.
