The electric telescopic rod 14 will be started to extend and push the connecting head 15 to move upward. The connecting head 15 will drive the connecting rod 12 to move upward. At the same time, the connecting rod 12 will rotate with the connecting head 15.

At this time, since the electromagnet 33 repels the magnetic block 34, the electromagnet 33 pushes the magnetic block 34 to move upward along the fixed rod 27 through the slide plate 28 by magnetic force. The slide plate 28 drives the insertion rod 29 to move upward, so that the insertion rod 29 is inserted into the insertion hole 30, thereby no longer locking the connecting rod 12 and the sliding rod 11.

The fence assembly includes a first avoidance groove 18, and the first avoidance groove 18 is opened at the bottom of the connecting rod 12. A slide tube 19 is rotatably connected in the first avoidance groove 18, and a moving rod 24 is slidably connected in the slide tube 19. A second avoidance groove 20 is opened on one side of the slide rod 11. The first baffle rod 23 is rotatably connected, one end of the first baffle rod 23 is rotatably connected to the second baffle rod 25, one end of the second baffle rod 25 is rotatably connected to the fixing frame 13, and the fixing frame 13 is fixed to the lifting platform 6, the rotation point of the first baffle rod 23 and the second baffle rod 25 is in contact with the moving rod 24, the sliding rod 11 will push the first baffle rod 23 to move when moving, the first baffle rod 23 will rotate with the sliding rod 11, and at the same time, the first baffle rod 23 will rotate with the second baffle rod 25, and when the second baffle rod 25 and the first baffle rod 23 rotate, they will push the moving rod 24 to move into the sliding tube 19, so that the moving rod 24 and the sliding tube 19 move.

[0032] The working principle of this embodiment is as follows: when in use, the oil cylinder 3 is extended to push the guide frame 2 to move upward along the frame body 1, and the frame body 1 will drive the lifting platform 6 to move upward, and the lifting platform 6 will move upward to drive the second contact 8 to move upward. When the second contact 8 moves upward to fit with the first contact 5, the electric telescopic rod 14 will be energized, and the electric telescopic rod 14 will be started to extend to push the connector 15 to move upward, and the connector 15 will drive the connecting rod 12 to move upward, and at the same time, the connecting rod 12 will generate a force between the connecting rod 12 and the connecting head 15. When the electric telescopic rod 14 is energized, the electromagnet 33 is energized. At this time, since the electromagnet 33 and the magnetic block 34 repel each other, the electromagnet 33 will push the magnetic block 34 to move upward along the fixed rod 27 through the slide plate 28 through the magnetic force. The slide plate 28 will drive the insertion rod 29 to move upward, so that the insertion rod 29 is inserted into the insertion hole 30, and the connecting rod 12 will drive the slide bar 11 to move along the guide groove 10 through the slide block 22 when moving. At the same time, the slide bar 11 will rotate with the connecting rod 12. When the electric telescopic rod 14 is retracted, the connecting rod 12 and the sliding rod 11 are in a vertical state, thereby blocking the lifting platform 6 and closing the door, so that the door on the lifting platform 6 is automatically opened and closed, and the staff does not need to manually open and close it, thereby avoiding injuries caused by falling, thereby improving the safety of the lift. However, when the lifting platform 6 continues to rise, the first contact 5 is disengaged from the second contact 8, thereby powering off the electromagnet 33. At this time, the electromagnet 33 no longer has magnetic force, and the slide plate 28 will move downward under the action of gravity, so that the insertion rod 29 is inserted into the socket 30, and the connecting rod 12 and the sliding rod 11 are locked and fixed, avoiding accidental touch to open the door during the lifting of the lifting platform 6, further improving the safety of the lift.
