At this time, the abutting rod 63 cannot push the separation rod 61 to move, and the abutting rod 63 flips over. The driving motor 33 drives the driving disk 35 to rotate, and the driving disk 35 drives the abutting rod 63 to rotate. When the other abutting rod 63 contacts the separation rod 61, the abutting rod 63 pushes the separation rod 61 to move, and the separation rod 61 drives the switch stator 58 to move, so that the switch stator 58 is in contact with the switch. The closing piece 57 is separated, and the locking block 75 locks the separation rod 61 at the same time, and the driving motor 33 returns to the initial position. When the driving gear ring 32 drives the driving shaft 34 to rotate again, the control block 56 extends out of the control slot, and the L-shaped push rod 73 is separated from the first inclined surface 711. The second spring 72 drives the mounting block 71 to move, and the mounting block 71 drives the locking block 75 to disengage from the plug-in slot, thereby releasing the limit on the separation rod 61, and the separation spring 62 drives the separation rod 61 to return to the initial position, so that it is convenient for continued use next time.

[0043] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
