A first telescopic member 403 is arranged on the first bottom plate 401, and the telescopic end of the first telescopic member 403 faces the sliding block 3.
[0052] In this embodiment, in order to ensure that the lateral moving member 4 can drive the leg to stretch, a first telescopic member 403 is provided. After the first telescopic member 403 expands and contracts, it drives the first slider 402 to slide laterally. A sliding block 3 is provided at the bottom of the fixing frame 2. When sliding laterally, the sliding block 3 slides in the second sliding groove 4021.
[0053] Furthermore, it further includes a slideway 6. The slideway 6 is provided at both ends of the first bottom plate 401. Second sliders 7 are provided at both ends of the first slider 402. The second sliders 7 are respectively slidably arranged in the two slideways 6.

Both ends of the second telescopic member 502 are respectively rotatably arranged on the two second bottom plates 501 and the lower bed 102.
[0056] In this embodiment, in order to allow the patient to perform leg-lifting exercises, a split-type bed body 1 is provided. The patient lies on the upper bed 101 and the legs are placed on the lower bed 102. After the second telescopic member 502 expands and contracts, it drives the lower bed 102 to move upward, enabling the patient's legs to be lifted. The lower end of the second telescopic member 502 is hinged to the second bottom plate 501, and the upper end is hinged to the lower bed 102 to ensure that the second telescopic member 502 will not get stuck after expanding and contracting.
[0057] Furthermore, the fixing frame 2 includes a fixing belt 201. The fixing belt 201 is provided on the upper bed 101. There are two first brackets 202. The two first brackets 202 are provided at both ends of the fixing belt 201. One end of the first bracket 202 away from the fixing belt 201 has a rotating ball. One end of the second bracket 203 close to the first bracket 202 has a ball groove 2031. The rotating ball is hinged in the ball groove 2031.

When the patient's leg needs to be lifted, the clamping block 207 disengages from the fifth clamping groove 2061. When the patient's leg needs to be fixed, the clamping block 207 enters the fifth clamping groove 2061. At this time, the clamping post 206 no longer rotates, thus ensuring the fixation of the leg.
[0061] Further, one end of the fourth bracket 211 away from the third bracket 204 has a plurality of third clamping grooves 2051. The fixing frame 2 further includes a fifth bracket 208. One end of the fifth bracket 208 close to the fourth bracket 211 has a plurality of fourth clamping grooves 2081. The plurality of fourth clamping grooves 2081 cooperate with the plurality of third clamping grooves 2051. There are a plurality of second clamping blocks 209. The plurality of second clamping blocks 209 connect the plurality of third clamping grooves 2051 and the fourth clamping grooves 2081. The foot plate 210 is arranged at one end of the fifth bracket 208 away from the fourth bracket 211. The sliding block 3 is rotatably arranged at the lower end of the foot plate 210.
[0062] In this embodiment, it can be adjusted according to the size of the patient's calf. The fourth clamping groove 2081 and the third clamping groove 2051 between the fourth bracket 211 and the fifth bracket 208 are in mutual abutment. The second clamping block 209 is inserted into the fourth clamping groove 2081 and the third clamping groove 2051, and the clamping position of the corresponding second clamping block 209 can be adjusted according to the size of the patient's leg.
