[0008] Through the above technical solution, the adjusting disk, the lifting plate and the climbing gear form a clutch structure. When the adjusting disk rotates, the climbing groove lifts the climbing block, causing the lifting plate and the climbing gear to move upward, so that the climbing gear is engaged with the reduction gear system, thereby controlling the rotation of the climbing gear.

[0009] Preferably, a plurality of limiting grooves distributed in a circumferential shape are provided through the surface of the climbing gear, and a plurality of the limiting blocks are slidably connected to the limiting grooves of the climbing gear.

The bottoms of the several climbing grooves are arranged in an arc shape, and the climbing blocks are slidably connected to the inner wall of the climbing groove.

[0011] Preferably, a reset spring is provided below the climbing gear, the reset spring is located above the adjusting disk, and the reset spring is sleeved with the handle rotating member.

[0012] Preferably, a fixed connection seat is fixedly connected to one side of the load-bearing sealing cover, and a resistance spring piece with a "U" shape is provided at the position of the fixed connection seat, and the resistance spring piece clamps the climbing block.

[0013] Preferably, the bearing sealing cover is fixedly connected to a driving motor at a position away from the handle rotating member.

[0016] The working principle is as follows: by starting the driving motor, the driving motor drives the driving worm and the reduction gear system to rotate, and drives the limit block to climb through the limit slot, and drives the limit block to rotate through the limit slot. The limit block and the jacking plate are acted upon by the resistance spring, so that the resistance spring hinders the deceleration of the jacking plate, generates an upward force, and realizes the climbing of the jacking plate, presses the climbing block into the climbing slot of the adjusting disk, realizes the locking of the adjusting disk, rotates the driving motor in the opposite direction, causes the limit block to lose the climbing force, and causes the adjusting disk to rotate in the opposite direction and reset under the action of the resistance spring, and the jacking plate is reset under the action of the reset spring, thereby realizing reset.
