The upper arm support component, the forearm support component, and the back-of-hand support component are all connected to fixing straps. The controller is used to control the state of the drive component and the first motor. The fastener includes a U-shaped clamping member connected to the backrest of the seat. A bolt is threaded onto one side wall of the U-shaped clamping member. A clamping member is connected to one end of the bolt inside the U-shaped clamping member. An airbag is provided on the inner wall of the clamping member and the U-shaped clamping member. The drive assembly includes a screw rotatably connected to the backrest of the seat, a nut threadedly connected to the screw, the nut being slidably connected to the backrest of the seat, and a linkage rod rotatably connected to the nut; the seat is equipped with a second motor that drives the screw to rotate; as the screw rotates, the support member rotates toward or away from the ground; One end of the screw has a groove, and a pawl is rotatably connected in the groove. A first spring is connected between the pawl and the bottom wall of the groove. The backrest of the seat is rotatably connected to an inner ratchet, which is coaxially sleeved on the outside of the screw and cooperates with the pawl. An eccentric cam is coaxially fastened to the inner ratchet. An air cylinder is connected to the backrest of the seat. The inflation end of the air cylinder is connected to a connecting rod, which slides against the eccentric cam. The air inlet and outlet ends of the air cylinder communicate with the airbags provided on the inner walls of the clamping member and the U-shaped clamping member.

2.
