[0013] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: when the device as a whole needs to be folded, the present invention controls the driving motor to work, so that the driving motor drives the adjusting threaded screw to rotate during operation, and at the same time, the ball nut pair connected to the outer thread of the adjusting threaded screw moves on the outer side of the adjusting threaded screw. When the ball nut pair moves, the ball nut pair drives the movable adjusting plate to move forward, so that the electric telescopic rod on the movable adjusting plate pulls the active frame, and when the active frame is subjected to force, the telescopic rod and the rotating block 2 are pulled, and the sliding guide block is pulled at the same time, so that the sliding guide block slides inside the guide sliding groove, and at the same time, the guide sliding groove is subjected to force, so that the slope guard plate rotates inside the positioning rotating frame, and the slope guard plate rotates inside the positioning rotating frame toward the top of the driving working box, thereby reducing the overall volume of the device and making the device more convenient to carry; When it is necessary to adaptively adjust the slope angle, the driving motor is controlled to work, so that the driving motor drives the adjusting threaded screw to rotate, so that the ball nut pair moves on the outside of the adjusting threaded screw, and at the same time, the position of the movable adjusting plate is adjusted. When the movable adjusting plate moves to the rear side of the top of the driving working box, the electric telescopic rod is controlled to work, so that the electric telescopic rod pushes the active frame. At this time, the rotating block 1 in the active frame is forced to push the telescopic rod. When the telescopic rod is forced, the other end pushes the rotating block 2, so that the rotating block 2 rotates in the sliding guide block, so that the sliding guide block is forced. At the same time, the sliding guide wheel on the outside of the sliding guide block slides in the guide sliding groove on the slope guard plate, so that the sliding guide wheel can push the guide sliding groove, and the guide sliding groove is forced to make the slope guard plate rotate on the inside of the positioning rotating frame, and the slope guard plate fits the outside of the slope, so that the device can be adaptively adjusted according to the angle of the slope when in use; When the ball nut pair moves backward on the outside of the adjusting threaded screw, the ball nut pair synchronously drives the moving arm plate to move, so that the extension spring on the moving arm plate contacts the airbag. At this time, the extension spring squeezes the airbag, so that the air in the airbag is sent into the connecting pipe, and at the same time, the air in the connecting pipe is sent into the adjusting box, so that the pressure inside the adjusting box is increased, and the spring is stretched. When the spring is stretched, the sliding sealing plate and the connecting piece are exposed from the adjusting box. By setting the mounting holes on the connecting piece, it is convenient to connect the devices. When the ball nut pair continues to move backward, the extrusion plate is attached to the surface of the airbag. At this time, the extension spring is stretched, so that the extrusion plate continues to fit the surface of the airbag, so that the airbag cannot rebound, and the air in the airbag is retained in the adjusting box, ensuring that the extrusion plate can always fit and squeeze the surface of the airbag when the ball nut pair drives the moving adjusting plate to move.

[0025] When the device as a whole needs to be folded, the driving motor 201 is controlled to work, so that the driving motor 201 drives the adjusting screw 202 to rotate during operation, and the ball nut pair 203 connected to the outer thread of the adjusting screw 202 moves on the outer side of the adjusting screw 202. When the ball nut pair 203 moves, the ball nut pair 203 drives the movable adjusting plate 205 to move forward, so that the electric telescopic rod 301 on the movable adjusting plate 205 pulls the active frame 302. When the active frame 302 is stressed, the telescopic rod 304 and the rotating block 2 305 are pulled, and the sliding guide block 306 is pulled, so that the sliding guide block 306 slides inside the guide sliding groove 308.

[0027] When the ball nut pair 203 moves backward on the outside of the adjusting threaded screw 202, the ball nut pair 203 synchronously drives the moving arm plate 408 to move, so that the extension spring 409 on the moving arm plate 408 contacts the airbag 402. At this time, the extension spring 409 squeezes the airbag 402, so that the air in the airbag 402 is sent into the connecting pipe 403.
