First connection blocks 7 for connection are threadedly sleeved on the two opposite threaded portions of the bidirectional threaded rod 5. By rotating the bidirectional threaded rod 5, the two first connection blocks 7 slide inside the left adjustment groove 4. A second connection block 8 for connection is slidably sleeved on the outer surface of the guide rod 6. The first connection block 7 and the second connection block 8 are both slidably connected inside the adjustment groove 4. Through the opening of the adjustment groove 4, it is convenient to limit the movement trajectories of the first connection block 7 and the second connection block 8. Grooves are provided on the surfaces of the first connection block 7 and the second connection block 8.
[0027] Two second side support plates 9 for facilitating the restriction and protection of patients are provided between the two first side support plates 3. The left end of the second side support plate 9 is rotatably connected through a shaft body in the groove provided on the surface of the second connection block 8. Both ends of the second side support plate 9 are provided with arc surfaces, so as to avoid the situation of collision between the second side support plate 9 and the second connection block 8. By moving the two first connection blocks 7, the two second side support plates 9 will move synchronously. An L-shaped sliding groove 10 extending to the outside is provided inside the right end of the second side support plate 9. An L-shaped block 11 is slidably connected inside the L-shaped sliding groove 10. Through the opening of the L-shaped sliding groove 10, it is convenient to limit the movement trajectory of the L-shaped block 11. When the vertical rod of the L-shaped block 11 is toggled, the vertical rod of the L-shaped block 11 will slide in the vertical groove of the L-shaped sliding groove 10, and the horizontal rod of the L-shaped block 11 will slide in the horizontal groove of the L-shaped sliding groove 10. A clamping groove 12 for fixing the position of the second side support plate 9 is provided inside the first connection block 7. The clamping groove 12 is adapted to the L-shaped block 11.
[0028] The vertical rod of the L-shaped block 11 and the L-shaped sliding groove 10 are fixedly connected with a spring 13 for facilitating the reset of the L-shaped block 11. When the L-shaped block 11 moves, the spring 13 will be deformed, and the movement of the second side support plate 9 will drive the movement of the two second connecting blocks 8. When the second connecting block 8 slides inside the adjustment groove 4, the guide rod 6 will limit its movement trajectory, and finally the position of the two second side support plates 9 can be adjusted. Subsequently, the patient can perform core stability training such as spinal flexion, extension, and scoliosis.

The upper surface of the base plate 1 is provided with a mounting groove 17, and an adjustment component is provided inside the mounting groove 17.
[0029] The driving assembly includes a first motor 14, the output shaft of the first motor 14 rotates and passes through the interior of the first side support plate 3 on the right side, and the front end of the bidirectional threaded rod 5 also rotates and passes through the interior of the first side support plate 3 on the right side. The output shaft of the first motor 14 is fixedly connected to a first bevel gear 15 that plays a transmission role. Starting the first motor 14 drives the rotation of the first bevel gear 15, and the front end of the bidirectional threaded rod 5 is fixedly connected to a second bevel gear 16 that also plays a transmission role. The first bevel gear 15 and the second bevel gear 16 are meshed and connected. The rotation of the first bevel gear 15 drives the rotation of the second bevel gear 16, and the rotation of the second bevel gear 16 drives the rotation of the bidirectional threaded rod 5.
[0030] The adjustment assembly includes a rotating rod 19, which is rotatably connected to the inside of the mounting groove 17. The outer surface of the rotating rod 19 is fixedly sleeved with a mounting plate 18. Both ends of the mounting plate 18 are set to arc surfaces, so as to avoid collision between the mounting plate 18 and the mounting groove 17 as much as possible. A lower limb fixing mechanism 20 is provided on the upper side of the mounting plate 18. A positioning groove 2001 is provided on the side of the fixing plate of the lower limb fixing mechanism 20 to facilitate fixing the lower limb fixing mechanism 20. A cavity 21 is provided inside the bottom plate 1, and the surface of the bottom plate 1 is fixedly connected to The L-shaped mounting plate 22, the rotating rod 19 rotates to pass through the bottom plate 1 and is rotatably connected to the vertical plate of the L-shaped mounting plate 22. The rotation of the rotating rod 19 can drive the mounting plate 18 to rotate inside the mounting groove 17. The rotation of the mounting plate 18 can realize the adjustment of the inclination angle of the lower limb fixing mechanism 20. The surface of the L-shaped mounting plate 22 is fixedly connected to the second motor 23, and the output shaft of the second motor 23 is fixedly connected to the rotating rod 19. By starting the second motor 23, the rotation of the rotating rod 19 is driven, and a positioning component is provided on the outer surface of the rotating rod 19.
[0031] In the above embodiment, the second motor 23 is preferably a self-locking motor. The self-locking property of the self-locking motor can prevent the rotating rod 19 from rotating due to the user stepping on it, thereby ensuring the overall stability of the device.
[0032] The positioning assembly includes an L-shaped sliding plate 24, the vertical plate of the L-shaped sliding plate 24 is movably sleeved on the outer surface of the rotating rod 19, the horizontal plate of the L-shaped sliding plate 24 slides into the interior of the mounting groove 17, the horizontal plate of the L-shaped sliding plate 24 is adapted to the positioning groove 2001, and the surface of the vertical plate of the L-shaped sliding plate 24 is rotatably connected with a movable sleeve 25.
[0033] The movable sleeve 25 is movable through the interior of the base plate 1. One end of the movable sleeve 25 located outside the base plate 1 is rotatably connected to an operating disk 26. By pulling the operating disk 26 outward, the operating disk 26 will drive the movable sleeve 25 to slide on the outside of the rotating rod 19. The operating disk 26 is movably sleeved on the outside of the rotating rod 19. A tension spring 27 is fixedly connected between the operating disk 26 and the surface of the base plate 1. The tension spring 27 is wrapped around the outside of the movable sleeve 25. The movement of the operating disk 26 will cause the tension spring 27 to deform.
[0034] Working principle:
[0035] When the core stabilization trainer is in use, the patient uses the lower limb fixing mechanism 20 to fix the legs. When the position of the two second side support plates 9 needs to be adjusted later, the first motor 14 is started to drive the rotation of the first bevel gear 15, and the rotation of the first bevel gear 15 drives the rotation of the second bevel gear 16. The rotation of the second bevel gear 16 drives the rotation of the bidirectional threaded rod 5. The rotation of the bidirectional threaded rod 5 enables the two first connecting blocks 7 to slide inside the left adjustment slot 4. The movement of the two first connecting blocks 7 drives the two second side support plates 9 to move synchronously. Subsequently, the movement of the second side support plate 9 drives the movement of the two second connecting blocks 8, and when the second connecting block 8 slides inside the adjustment slot 4, the guide rod 6 limits its motion trajectory, and finally realizes the adjustment of the position of the two second side support plates 9, and the patient can subsequently perform core stabilization training such as spinal flexion, extension, and scoliosis;
[0036] When the core stabilization training of the subsequent patient is finished, the vertical rod of the L-shaped clamping block 11 is toggled, and the vertical rod of the L-shaped clamping block 11 will slide in the vertical groove of the L-shaped sliding groove 10, and the cross rod of the L-shaped clamping block 11 will slide in the cross groove of the L-shaped sliding groove 10, and when the L-shaped clamping block 11 moves, the spring 13 will be deformed. After the L-shaped clamping block 11 moves, the cross rod of the L-shaped clamping block 11 will be disengaged from the inside of the clamping groove 12, and the second side support plate 9 can be disengaged from the first connecting block 7. The patient can then be made to get off the device by rotating the second side support plate 9, without the patient having to bend over or do other actions to get out of the tic-tac-toe shape formed by the device, thereby avoiding the situation where cerebral palsy rehabilitation patients fall or stand unsteadily;
[0037] When the inclination angle of the lower limb fixing mechanism 20 needs to be adjusted subsequently, start the second motor 23 to drive the rotation of the rotating rod 19. Through the rotation of the rotating rod 19, the mounting plate 18 can be driven to rotate inside the mounting groove 17. Through the rotation of the mounting plate 18, the adjustment of the inclination angle of the lower limb fixing mechanism 20 can be realized, thereby improving the flexibility of the device, facilitating the adjustment of the pitch angle of the lower limb fixing mechanism 20 according to the rehabilitation situation of the patient, and facilitating the adjustment according to the usage requirements. At the same time, since both the moving sleeve 25 and the operation disk 26 are movably sleeved outside the rotating rod 19, the rotation of the rotating rod 19 will not drive the rotation of the moving sleeve 25 and the operation disk 26;
[0038] When the lower limb fixing mechanism 20 needs to be disassembled or replaced, pull the operation disk 26 outwards. At this time, the operation disk 26 will drive the moving sleeve 25 to slide outside the rotating rod 19, and the movement of the operation disk 26 will cause the tension spring 27 to deform. At this time, through the sliding of the moving sleeve 25, the movement of the L-shaped sliding plate 24 can be driven, so that the L-shaped sliding plate 24 can be disengaged from the inside of the positioning groove 2001, and finally the disassembly or replacement of the lower limb fixing mechanism 20 can be realized.
[0039] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
