In this embodiment, since the output gear 43 is located right below the driving motor 1, the three-dimensional space is further effectively utilized, and the output of the ultra-large torque can be realized in a limited space.
Wherein, actuating mechanism's transmission principle does: the driving motor 1 drives the output belt wheel to rotate, the output belt wheel drives the first output belt wheel 23 and the second output belt wheel 24 to rotate through the synchronous belt 22, the first output belt wheel 23 and the second output belt wheel 24 respectively drive the first speed reducer 31 and the second speed reducer 32 to rotate, further, the first input teeth on the first speed reducer 31 and the second input teeth on the second speed reducer 32 rotate, the output gear 43 is driven to rotate through the meshing of the first input gear 41 and the second input gear 42 with the output gear 43, the output gear 43 is connected with the head body of the swing head through the connecting shaft, and further, a large enough torque is provided for the output gear.

Since the first input gear 41 is a gear that mainly provides a meshing force when the first input gear 41 and the second input gear 42 rotate clockwise, the transmission accuracy of the gear at this time mainly depends on the engagement of the first tooth face of the first input gear 41 and the first tooth face of the teeth in the output gear 43, and when the first input gear 41 and the second input gear 42 rotate counterclockwise, the second input gear 42 is a gear that mainly provides a meshing force, and at this time, the transmission accuracy of the gear mainly depends on the engagement of the second tooth face of the second input gear 42 and the second tooth face of the teeth in the output gear 43.
