The first motor 22 drives the first connecting wheel 23 outside its main shaft to rotate. During the rotation of the first connecting wheel 23, the second connecting wheel 25 is driven to rotate through the belt at the same time. During the rotation of the second connecting wheel 25, the first threaded rod 24 fixedly connected to the second connecting wheel 25 is driven to rotate at the same time. The threads on the surfaces of the first threaded rod 24 are relatively arranged. At this time, the rotation of the first threaded rod 24 will simultaneously drive the two threaded first splints 26 to move toward the middle, thereby driving the first The arc-shaped structure at the end of the splint 26 clamps the staff's head and thus fixes the head. When the staff's legs need to be fixed, the user sets the first fixing sleeve 216 inside the second fixing sleeve 217. At this time, the user rotates the rotating handle 218 to drive the fixing joint 219 to rotate. Since the fixing joint 219 is eccentrically connected to the rotating handle 218, when the fixing joint 219 rotates, one side of the fixing joint 219 will press against the inner side of the first fixing sleeve 216. As the fixing joint 219 continues to rotate, the fixing joint 219 will firmly fix the inner side of the first fixing sleeve 216. At this time, the user places the legs between the two second splints 214, and then starts the second motor 210 to drive the fourth connecting wheel 211 through the third connecting wheel 212. The connecting wheel 213 rotates, thereby driving the two second splints 214 to clamp toward the middle. The end of the second splint 214 can fix the user's legs. A rotatable first threaded rod 24 is installed on the inner side of the end of the two first splints 26. By rotating the first threaded rod 24, the first splints 26 on both sides are moved closer to the middle, so as to achieve a firm clamping of the user's head. This design allows fine adjustment to ensure the comfort and safety of users with different head shapes. The effective fixation of the head and feet can significantly reduce the risk of shaking or accidents caused by the user during the stair sliding process, protecting the user from injury. The silicone structure and adjustable design of the end of the first splint 26 enable the device to adapt to the body shape and needs of different users, providing a more personalized comfort experience. The quick-detachable mounting bracket 29 is designed to not only facilitate quick response by medical staff or users in emergency situations, but also simplifies the process of daily cleaning and maintenance, and improves the efficiency of equipment use. The adjustable first splint 26 and second splint 214 can adapt to users of different body shapes and needs, increasing the versatility and applicability of the device. The ventilation holes 27 provided on the first splint 26 have multiple significant benefits. First, the design of the ventilation holes 27 can significantly improve the user's comfort. Because when using a wheelchair to glide, especially for a long time or in a high temperature environment, the head is prone to sweating. The ventilation holes 27 can effectively promote air circulation, reduce the stuffiness of the head, and avoid the discomfort caused by sweat accumulation. Secondly, good breathability also helps to reduce the humidity in the scalp area.Reducing the environment for bacterial growth is beneficial to maintaining the health of the head skin and preventing the occurrence of skin diseases. In addition, the air holes 27 can also allow the first splint 26 to fit the contour of the user's head better, and by reducing air resistance, the first splint 26 is more stable when fixed, further enhancing the safety of use. In summary, the design of the air holes 27 on the first splint 26 not only improves the user's comfort, but also promotes health and enhances the fixation effect.
