[0045] The second motor 810 drives the worm 89 to rotate, and the worm 89 is then used to drive the worm wheel 88 and the sub-shaft 87 and the bevel gears 86 at both ends to rotate. The bevel gear 86 at the end of the sub-shaft 87 is meshed with the bevel gear 86 at the end of the transverse screw rod 83, so that the transverse screw rods 85 on both sides rotate at the same time, and the threads of the transverse screw rod 85 and the transverse rack 83 are matched, and the transverse rack 83 is also slidably installed with the transverse slide rail 84 on the same side, so that the transverse rack 83 can be controlled to slide in the transverse slide rail 84. When the transverse rack 83 moves, the meshing transmission between the second gear 82 can be used to control the rotation of the second gear 82, and at the same time drive the main shaft 81 and the leg support plate 7 to rotate relative to the bed board 2, thereby realizing the angle adjustment of the leg support plate 7, such as Figure 3 The state shown in the figure can be adjusted to the state shown in the figure, and the back plate 3 is adjusted to Figure 3 When the user is in the state shown in , the user can perform corrective training of sitting posture.

Figure 8 As shown in the figure, the three leg correction components 9 are arranged in the form shown in the figure. When in use, the user's legs are placed between the three leg correction components 9.

The reason is that the spring slide bar 96 and the torsion spring shaft 97 have a buffering effect. The purpose is to avoid unnecessary squeezing damage to the legs due to overly rigid force. At the same time, the user's legs can be properly moved during correction training, avoiding discomfort or pain in the leg joints and muscles caused by long-term correction training, improving the comfort of training, and making correction training easier for users, especially children.
