[0044] As shown in the above structure, the third shell 3 is connected to the second shell 2 and the connecting block 4 through the connecting plate 31. The third shell 3 is a detachable structure, which is convenient for adjusting the connection structure between the motor and the reversing assembly to ensure the stability of the transmission structure. At the same time, this connection method can further improve the connection stability of the second shell 2, the third shell 3 and the connecting block 4; it is also convenient for positioning the second shell 2, the third shell 3 and the connecting block 4 during assembly.

[0045] like Figure 3 As shown, the side of the accommodating shell 32 away from the second shell 2 is provided with an opening, and the first sealing plate 5 seals the opening of the accommodating shell 32;
