The motor 41 can also be directly connected with the connecting rod 42, but larger motor driving force is needed, and the motor driving force can be amplified by connecting the transmission assembly 45 with the connecting rod 42 through the connection of the motor 41 and the transmission assembly 45, so that the cost of the motor 41 is reduced.

In some alternative embodiments, referring to fig. 15, the transmission assembly 45 includes a first gear 451 and a second gear 452, the first gear 451 is disposed on the motor shaft of the motor 41, the second gear 452 is connected to the rotation shaft of the link 42 to rotate the link 42, a third gear 453 and a fourth gear 454 are engaged with each other, the third gear 453 is engaged with the first gear 451, and the fourth gear 454 is engaged with the second gear 452, which effectively ensures the transmission efficiency of the transmission assembly 45. Further optionally, the outer diameters D1, D2, D3, D4 of the first gear 451, the second gear 452, the third gear 453, and the fourth gear 454 are sized to satisfy: d4 < D1 < D2 < D3. With such an arrangement, the driving force of the external driving device 4 can be easily amplified, and the cost of the motor 41 can be reduced. Of course, the present invention is not limited thereto. Conventional assemblies 45 may also be designed to determine the number of gears and the ratio of outer diameters used.
