[0029] It should be noted that by starting the motor 47, the front rotating wheel 49 is driven to rotate clockwise, thereby driving the gear 2 405 to rotate clockwise, thereby causing the front half-toothed gear 402 to rotate clockwise, and the half-toothed gear 402 is meshed with the right gear 1 401, thereby causing the right gear 1 401 to rotate counterclockwise, thereby driving the threaded rod 42 to rotate counterclockwise, and the threaded rod 42 is threadedly connected with the threaded plate 44, thereby driving the threaded plate 44 to move to the right. When the half-toothed gear 402 rotates half a circle, it will not mesh with the gear 1 401. At this time, the rear half-toothed gear 402 will mesh with the front gear 1 401, and the gear 2 405 is set to rotate clockwise, thereby making the meshing gear 3 406 rotate counterclockwise, thereby driving the front rotating wheel 49 to rotate counterclockwise, thereby making the rear rotating wheel 49 rotate counterclockwise, thereby driving the rear half-toothed gear 402 to rotate counterclockwise, thereby making the threaded rod 42 rotate clockwise, and the motor 47 continues to rotate, thereby making the support plate 51 move back and forth left and right, thereby making the patient's legs repeatedly bend and stretch, thereby achieving a better therapeutic effect on the knee joint.

[0035] It should be noted that by pulling the card rod 57 upward, the limit plate 58 is driven to move upward, thereby compressing the spring 59. At this time, the card rod 57 will be disengaged from the card slot 56, and then the two protective covers 54 are rotated to both ends respectively, so that the patient's feet are fitted on the support plate 51, and then the two protective covers 54 are rotated inwardly so that the protective covers 54 cover the feet. A cushion 53 is provided on the inner wall of the protective cover 54. The material of the cushion 53 is relatively soft and can fit the feet more closely without causing too much squeezing feeling to the feet. The card slot 56 on the fixing block 55 is aligned with the card rod 57, and the card rod 57 is released at this time. Under the action of the spring 59, the card rod 57 is moved downward, so that the card rod 57 slides into the card slot 56, and then the base plate 1 and the protective cover 54 are fixed, so that the feet can be fixed, so that the legs will not deviate when bent, thereby achieving a better treatment effect.

[0041] It should be noted that the cushion 53 is made of a relatively soft material, which can fit the feet more closely, and at the same time will not cause too much pressure on the feet.

[0042] The working principle of the utility model is as follows: first, the patient with knee joint disease sits on the bottom plate 1, with the back against the backrest 2 and the head against the headrest 3, and by pulling the clamping rod 57 upward, the limit plate 58 is driven to move upward, thereby compressing the spring 59, and the clamping rod 57 will be out of the clamping slot 56 at this time, and then the two protective covers 54 are rotated to both ends respectively, and the patient's feet are attached to the support plate 51, and then the two protective covers 54 are rotated inwardly so that the protective covers 54 cover the feet, and the inner wall of the protective cover 54 is provided with a soft cushion 53. The cushion 53 is made of a soft material and can fit the feet better without causing too much squeezing to the feet. The slot 56 on the fixing block 55 is aligned with the locking rod 57. At this time, the locking rod 57 is released. Under the action of the spring 59, the locking rod 57 moves downward, so that the locking rod 57 slides into the slot 56, and then the bottom plate 1 and the protective cover 54 are fixed. Then, the feet can be fixed so that the legs will not deviate when bent, achieving a better treatment effect. By starting the motor 47, the front wheel 49 is driven clockwise. The needle rotates, thereby driving the gear 2 405 to rotate clockwise, thereby causing the front half-toothed gear 402 to rotate clockwise, and the half-toothed gear 402 is meshed with the right gear 1 401, thereby causing the right gear 1 401 to rotate counterclockwise, thereby driving the threaded rod 42 to rotate counterclockwise, and the threaded rod 42 is threadedly connected with the threaded plate 44, thereby driving the threaded plate 44 to move rightward. When the half-toothed gear 402 rotates half a circle, it will not mesh with the gear 1 401. At this time, the rear half-toothed gear 402 will Engaged with the front gear 1 401, gear 2 405 is set to rotate clockwise, thereby making the meshing gear 3 406 rotate counterclockwise, thereby driving the front rotating wheel 49 to rotate counterclockwise, thereby making the rear rotating wheel 49 rotate the roller counterclockwise, thereby driving the rear half-tooth gear 402 to rotate counterclockwise, thereby making the threaded rod 42 rotate clockwise, and the motor 47 rotates continuously, thereby making the support plate 51 move back and forth left and right, thereby making the patient's legs repeatedly bend and stretch, thereby achieving a better therapeutic effect on the knee joint.
