[0030] The top end of the thigh supporting seat 322 and the top end of the calf supporting seat 323 are made of flexible rubber. The inner wall of the spherical groove 504 is spherical.

[0031] In specific use, first, the patient lies on the bed body 1. Then, the user controls the fixing servo motor 224 to work through the electric control panel 101. The fixing rod 222 is rotated on the side wall of the fixing groove 221 through the transmission of the rotating worm 223 and the rotating worm wheel 225. Thus, the fixing rod 222 is rotated from a horizontal state to a vertical state. Then, the fixing rod 222 is located between the roots of the two thighs of the patient. Thus, the technical effect of limiting and fixing the upper part of the patient is realized. The technical problem of complicated and tedious patient fixing in the prior art is solved effectively. Then, the user controls the adjusting servo motor 401 to work through the electric control panel 101. The sliding sleeve 403 is slid on the side wall of the sliding groove 321 through the transmission of the adjusting threaded rod 402. Thus, the lifting seat 405 and the knee supporting seat 406 are moved on the L-shaped supporting frame 312. The knee supporting seat 406 is moved below the knee of the patient. Then, the user controls the lifting hydraulic device 404 to work through the electric control panel 101. Thus, the height of the knee of the patient is adjusted. The technical effect of completing the stretching and bending of the legs of the patient without affecting the treatment space is realized. The technical problem of difficult and tedious adjustment of the posture of the patient in the prior art is solved effectively. Subsequently, the user can observe the length of the patient's thigh and calf, and then the user can control the adjustment of the hydraulic device one 324 and the adjustment of the hydraulic device two 325 through the electrical control panel 101. According to the previous observation of the length of the thigh, the length of the adjustment of the hydraulic device one 324 is adjusted, and then the length of the adjustment of the hydraulic device two 325 is adjusted according to the length of the calf. Finally, the thigh support seat 322 can be located at the root of the thigh, and the calf support seat 323 can be located at the ankle of the patient. In this way, the length of the patient's leg can be quantified and fixed, thereby achieving the technical effect of adapting to the patient's body shape, effectively solving the technical effect of the prior art that is difficult to adapt to the patient's complex shape. When it is necessary to adjust the posture of the patient's leg, the user can control the adjustment of the servo motor 401 and the lifting of the hydraulic device 404 through the electrical control panel 101. The lifting of the hydraulic device 404 can lift the knee of the patient to complete the operation of bending the leg. The adjustment of the servo motor 401 can slide the sliding sleeve 403 in the inner wall of the sliding groove 321. In this process, the thigh support seat 322 and the calf support seat 323 can always remain at the root of the thigh and the ankle of the calf. At the same time, the adjustment of the hydraulic device one 324 and the adjustment of the hydraulic device two 325 are in the locked state, which can always ensure that the knee of the patient's leg is located directly above the knee support seat 406. In this way, the technical effect of self-adapting to the patient's posture is achieved, and the process of adjusting the patient's posture is reduced, thereby improving the user's work efficiency. The user can control the synchronous servo motor 315 to work through the electrical control panel 101. The two L-shaped support frames 312 can be driven to rotate in the inner wall of the rotating groove 311 through the two synchronous gears 313. At the same time, the movable wheels 314 at the other end of the L-shaped support frames 312 can rotate on the ground to provide support for the L-shaped support frames 312. In this way, the technical effect of adjusting the angle of the patient's leg is achieved, effectively solving the technical problem of angle adjustment difficulty in the prior art. Subsequently, the user can place the patient's foot on the rotating seat 502, and the user can fix the patient's foot on the rotating seat 502 through the bandage. When the patient's posture is adjusted through the knee support mechanism 4 and the length adjustment mechanism 320, the patient's foot will move accordingly. In this way, the sliding seat 501 can be driven to slide in the inner wall of the sliding groove 321 through the spherical rotating block 503. At the same time, the spherical rotating block 503 is located in the inner wall of the spherical groove 504, and the rotating seat 502 can rotate relative to the sliding seat 501 according to the movement of the patient's foot. In this way, the technical effect of fixing the patient's foot is achieved, effectively solving the technical problem of no support and self-adaptive adjustment of the foot in the prior art. At the same time, the rotating hydraulic device 213 can be controlled to work through the electrical control panel 101 according to the patient's requirements. In this way, the rotating backrest 212 hidden in the inner wall of the hidden groove 211 can be rotated in the inner wall of the hidden groove 211. In this way, the technical effect of adjusting the posture of the patient's upper body is achieved, greatly improving the comfort of the patient.
