By arranging the leg muscle training device on the wheelchair, it is convenient for patients who sit or lie still for a long time to perform rehabilitation training, and compared with the fixed position of existing rehabilitation training instruments, this device can enable patients to perform rehabilitation training under the sun or fresh air, which is beneficial for patients to maintain a positive and healthy mood and is beneficial for rehabilitation. The motor 3 is a slow servo motor 3. Turn on the motor 3, slowly adjust the angle of the rotating shaft 2, and adjust the fixing rod 4 to a suitable height in front of the seat cushion, so that the patient has a more comfortable use experience.

A slide bar 5 is slidably connected between the two fixed rods 4, and a massage roller 6 is rotatably installed on the slide bar 5. The length of the massage roller 6 is the same as the distance between the two fixed rods 4, thereby ensuring that the legs are massaged. By setting the massage roller 6 to massage the legs, the vitality of the leg muscles is maintained.

The bottoms of the two fixing rods 4 are fixedly connected to the same base plate 7, and two groups of symmetrically arranged pull rods 8 are slidably connected through the base plate 7.
