The universal wheels 22 can provide structural support for the movement of the device.
[0025] Working principle: When in use, the handle 19 needs to be rotated to unfold the device. Rotating the handle 19 drives the worm 14 to rotate. The rotation of the worm 14 drives the worm wheel 15 to rotate. The worm wheel 15 pushes the two second sliders 17 to slide away from each other. The two second sliders 17 push the multiple push rods 18 to slide away from each other. The multiple push rods 18 push the two lifting columns 12 to slide away from each other, thereby realizing the unfolding of the device. When the elderly place their arms on the upper parts of the two first cushions 2, the elderly can hold the two grips 23 with both hands, and then start the electric push rod 3 by pressing the button on the left grip 23. The electric push rod 3 starts to push the first slider 4 to move upward. The first slider 4 drives the two connecting rods 5 to rotate and slide closer to each other at the same time. The two connecting rods 5 pull the two clamping plates 6 closer to each other. The two clamping plates 6 drive the two second cushions 10 to clamp on the left and right sides of the elderly's body under the armpits. Releasing the button on the left grip 23 can stop the electric push rod 3 from working. Since the two second cushions 10 are made of sponge material, the two second cushions 10 will not cause mechanical damage to the elderly. Then the elderly hold the two brake handles 24 with both hands and are ready to brake the device at any time and can try to move their bodies. Due to the clamping and supporting effect of the two second cushions 10, it can prevent the elderly from falling due to the loss of strength in the lower limbs and the sinking of the body. When the elderly need to stop actively, they can press the two brake handles 24 to brake the multiple universal wheels 22.
