[0082] It should be noted that the end of the first guide post 2011 is inserted into the inner side of the notch 2021; the sliding groove 2022 is adapted to the second guide post 2031, and the side wall of the second guide post 2031 squeezes the inner side of the sliding groove 2022; the rotation of the rotating sleeve 202 drives the second connecting shaft 203 to rotate; the second spring 2023 can push the rotating sleeve 202 to reset, ensuring that the position of the notch 2021 corresponds to the first guide post 2011; thereby, the rotation of the first connecting shaft 201 can drive the rotating sleeve 202 rotates; a guide groove 301 is opened inside the socket buckle 300, and the limit block 2032 is adapted to the guide groove 301. The rotation of the second connecting shaft 203 can drive the socket buckle 300 to rotate, and the socket buckle 300 can reciprocate along the axial direction of the second connecting shaft 203. The socket buckle 300 can be limited by the cooperation between the limit block 2032 and the guide groove 301, so as to ensure that the rotation of the second connecting shaft 203 drives the socket buckle 300 to rotate.

[0083] When in use, when the output end device connected to the sleeve buckle 300 is overloaded, the first connecting shaft 201 rotates to drive the first guide column 2011 to squeeze the inner wall of the notch 2021; the first guide column 2011 squeezes the rotating sleeve 202 along the inner wall of the notch 2021 to move; the first guide column 2011 moves to the end of the rotating sleeve 202, and the side wall of the first guide column 2011 contacts the end of the rotating sleeve 202; at this time, the second spring 2023 is in a compressed state, and during the compressed movement of the rotating sleeve 202, the second guide column 2031 moves along the trajectory of the sliding groove 2022, so that the second guide column 2031 is stuck to the horizontal position of the sliding groove 2022; then, the second guide column 2031 is matched with the sliding groove 2022, so that the position of the rotating sleeve 202 can be fixed; at this time, the first guide column 2011 rotates at the end of the rotating sleeve 202, so that the motor will not drive the second connecting shaft 203 to rotate; thereby, protection can be provided against overload, effectively avoiding overload damage to the motor;

[0084] Under normal circumstances at the output end, the rotation of the first connecting shaft 201 drives the first guide column 2011 to rotate, and the first guide column 2011 squeezes the inner wall of the notch 2021. The rotation of the first connecting shaft 201 drives the rotating sleeve 202 to rotate, so that the horizontal position of the sliding groove 2022 rotates to a position corresponding to the second guide column 2031, and then under the rebound force of the second spring 2023, the second guide column 2031 is pushed to the end of the sliding groove 2022, and then the rotating sleeve 202 rotates to drive the second connecting shaft 203 to rotate, and the rotation of the second connecting shaft 203 drives the sleeve buckle 300 to rotate; thereby, the sleeve buckle 300 can be driven to drive the wrench buckle to open the gate.

[0085] In summary, the overload unit 200 provided can effectively prevent the device from being overloaded during use, protect the motor to a certain extent, ensure the normal operation of the device, and at the same time make it easier for the device to open the gate.
