[0030] The slider 24 and the connecting shaft 42 are both provided with a locking mechanism 7 .

[0031] Specifically, the locking mechanism 7 includes a driving groove 71 opened inside the slider 24 and the connecting shaft 42 and a positioning groove 72 located on one side of the driving groove 71. Two tooth plates 73 are symmetrically arranged inside the driving groove 71. Both sides of the tooth plates 73 are provided with convex edges. A locking rod 74 located between the two tooth plates 73 is movably arranged inside the driving groove 71. One end of the locking rod 74 extends to the inside of the positioning groove 72, and the other end extends to the outside of the driving groove 71. A tapered portion is provided on the locking rod 74, and a spring is provided on the side of the convex edge away from the locking rod 74. Figure 1 , Figure 3 and Figure 5 When the fixing seat 3 is lifted up, one end of the fixing seat 3 drives the support arm 31 to pull the movable shaft 23 to slide inside the sliding groove 21, and at the same time, the movable shaft 23 drives the slider 24 to slide inside the limiting groove 22, and the slider 24 drives the tooth plate 73 to contact the tooth groove 25, and the tooth plate 73 retracts into the driving groove 71 and stretches the spring.

[0033] Specifically, one end of the top of the fixing seat 1 3 and the fixing seat 2 4 is provided with a strap 5, and the other end is provided with a hook 6 matching the strap 5, and the user's limbs can be limited by clamping the strap 5 on the hook 6.

[0034] Specifically, the top of the clamping seat 1 is provided with a stabilizing shaft 13 which is movably sleeved with the inside of the adjusting plate 2, and the surface of the stabilizing shaft 13 is provided with an outer gear ring 131. The interior of the adjusting plate 2 is provided with a through hole, and the internal thread of the through hole is sleeved with a locking bolt 26. The interior of the through hole is also movably provided with a tooth block 27 located at one end of the locking bolt 26, and a spring is provided between the locking bolt 26 and the tooth block 27. One end of the tooth block 27 extends to the inside of the outer gear ring 131, and the front section of the through hole is provided with a thread to cooperate with the locking bolt, and the rear section is square and sleeved with the tooth block 27. When the relative angle between the adjusting plate 2 and the clamping seat 1 needs to be adjusted, the adjusting plate 2 is rotated to drive the tooth block 27 to contact the outer gear ring 131. After selecting a suitable angle, the locking bolt 26 is screwed in to tighten the tooth block 27.

[0035] Specifically, a clamping plate 11 is provided inside the clamping seat 1, and a screw 12 is provided at the bottom of the clamping seat 1, one end of which is screwed into the clamping seat 1 and connected to the bottom of the clamping plate 11 through a bearing. The clamping seat 1 is clamped on the frame of the bed frame or the frame of the table, and the screw 12 is turned to contact the clamping plate 11 to rise and clamp the frame for use.
