The motor locking mechanism of claim 11 wherein said pin holder drive member comprises a spindle, a wrench coupled to said spindle, said wrench being at least partially located outside of said motor, said first rotating portion having a support portion for supporting said spindle, said support portion being adapted to limit movement of said spindle in a direction other than an axial direction of said spindle; the main shaft is fixedly connected with a cam, the pin boss is provided with a cam hole for accommodating the cam to rotate, and the cam hole is provided with a limit groove matched with the cam; the wrench drives the main shaft to move along the axial direction of the main shaft under the action of external force.

13. The motor locking mechanism of claim 12 wherein said spindle further comprises a threaded section; the rigid pushing piece is a cushion block in threaded connection with the main shaft, at least one surface of the cushion block is in contact with the inside of the first rotating portion, at least one of the end portion of the cushion block or the end portion of the pin base is provided with an inclined surface, and the inclined surface decomposes the horizontal thrust of the cushion block into vertical component force pointing to the direction of the lock groove.

14. The motor locking mechanism according to any one of claims 12 or 13, wherein the supporting portion is a supporting hole penetrating through a side wall of the first rotating portion, a pin is fixedly connected in the supporting hole, a guide groove matched with the pin is formed in a circumferential direction of the main shaft, the guide groove comprises a slant groove and a straight groove along the circumferential direction of the main shaft, and the straight groove is communicated with one end of the slant groove close to the wrench.

15. The motor locking mechanism according to claim 4, wherein the first rotating part is further provided with a guide hole, a push rod capable of moving axially along the guide hole, and the lock pin is positioned at the top end of the push rod; the elastic pushing piece comprises an elastic piece, a screw rod, a nut and a spanner;

wherein, a limit hole for installing a nut is arranged in the first rotating part; the nut is fixedly connected with a spanner, and the spanner is at least partially positioned outside the motor; the ejector rod is also provided with an elastic piece installation groove penetrating through the bottom of the ejector rod, the bottom of the installation groove is connected with a bottom cover with a through hole, the screw rod penetrates through the through hole, and a screw rod body in the installation groove is provided with a limiting bulge matched with the through hole; one end of the elastic part props against the screw rod, and the other end of the elastic part props against the inner wall of the ejector rod; and one end of the screw rod, which is positioned outside the mounting groove, is in threaded connection with the nut.

16. The motor locking mechanism of claim 15 wherein the rigid pusher comprises a top piece coupled to the threaded rod, the top piece being mounted between the nut and the bottom cap, the top piece being spaced from the bottom cap by a distance less than the length of the threads of the threaded rod engaged with the nut.

17. The motor locking mechanism of claim 16 wherein said top block is wedge shaped and said bottom cover has a wedge shaped slot for mating with said top block.

18. The motor locking mechanism of claim 15 wherein the bottom cover is threadably connected to the top bar.

19. An electric motor comprising a motor locking mechanism as claimed in any one of claims 1 to 18.
