[0032] Two convex blocks are fixedly connected to both sides of the bed body 1, a guide rod 8 is fixedly connected to one end of the two convex blocks on the same side close to each other, and a locking mechanism 5 for locking the moving plate 2 is arranged on the side wall of the guide rod 8;

[0033] A restraint mechanism 6 is arranged on the side wall of the guide rod 8, a fixing mechanism 7 for fixing the restraint mechanism 6 is installed on the restraint mechanism 6, and the fixing mechanism 7 is in threaded connection with the bed body 1;

[0034] The restraint mechanism 6 includes an L-shaped block 61, a first restraint belt 66 and a second restraint belt 67; an L-shaped block 61 is sleeved on the side wall of the guide rod 8, a fixing column 65 is installed on the upper part of the side wall of the L-shaped block 61, one end of a first restraint belt 66 is sleeved on the side wall of the fixing column 65, the middle of the lower end of the first restraint belt 66 is fixedly connected with a second restraint belt 67, a second loop surface of magic tape 16 is fixedly connected to the upper end of the bed body 1, and the second loop surface of magic tape 16 is adapted to a second hook surface of magic tape 68 fixedly connected to the lower end of the second restraint belt 67;

[0035] One end of the L-shaped block 61 far from the bed body 1 is fixedly connected with a first hook surface of magic tape 62, the lower surface of the other end of the first restraint belt 66 is fixedly connected with a first loop surface of magic tape 69, and the first loop surface of magic tape 69 is adapted to the first hook surface of magic tape 62;

[0036] A limiting mechanism for limiting the moving plate 2 is arranged on the bed body 1.

[0037] During use, the L-shaped block 61 is sleeved on the side wall of the guide rod 8. The lower surface of the other end of the first restraint strap 66 is adhered to the first hook surface 62 of another L-shaped block 61, and the second hook surface 68 is adhered to the second loop surface 16 at the upper end of the bed body 1, so as to restrain the user lying flat on the upper end of the bed body 1. Since the L-shaped block 61 can axially move along the side wall of the guide rod 8, it is convenient to quickly restrain different areas of the user's body. After restraint, the restraint mechanism 6 can be fixed to the bed body 1 by using the fixing mechanism 7. In addition, the moving plate 2 is placed on the upper end of the bed body 1, and the electric cylinder 3 can be opened to adjust the angle of the backrest 4. The backrest 4 can support the user's back and also support the user's legs.

[0038] Please refer to Figure 1 and Figure 4 In this embodiment, a first groove 63 is formed through the middle of one side of the L-shaped block 61. The other end of the first restraint strap 66 passes through the first groove 63 and extends to the outside of another L-shaped block 61. The first groove 63 provides a threading channel for the first restraint strap 66, enabling the first restraint strap 66 to pass through the L-shaped block 61 conveniently.

[0039] Please refer to Figure 1 and Figure 4 In this embodiment, a bearing block 64 is fixedly connected to the end of the L-shaped block 61 close to the center of the bed body 1. The upper end surface of the bearing block 64 is flush with the bottom inner wall of the first groove 63. The design that the bearing block 64 is flush with the bottom surface of the first groove 63 enables the first restraint strap 66 to maintain a horizontal and fitting state when passing through the first groove 63, avoiding wrinkles or suspension of the restraint strap, reducing friction with the skin of the child, and improving the stability of the restraint process.

[0040] Please refer to Figure 1 and Figure 5 In this embodiment, the locking mechanism 5 includes a screw groove 51, a sleeve block 52, a first bolt 53, a vertical block 54, and a second bolt 55. Rows of evenly distributed screw grooves 51 are formed at the lower end of the bed body 1 near both side edges. The side wall of the guide rod 8 is sleeved with a sleeve block 52. The lower end of the sleeve block 52 is threadedly installed with a first bolt 53. The first bolt 53 passes through the lower end of the sleeve block 52 and is threadedly installed on the inner wall of the screw groove 51. A vertical block 54 is fixedly connected to the upper end of the sleeve block 52. The side wall of the vertical block 54 is threadedly installed with a second bolt 55. Second fixing blocks 10 are fixedly connected to both sides of the moving plate 2. A screw hole is formed on the side of the second fixing block 10 away from the moving plate 2. The second bolt 55 passes through the vertical block 54 and is threadedly installed on the inner wall of the screw hole. Through the cooperation of the rows of screw grooves 51 and the first bolt 53, the locking mechanism 5 can flexibly select the fixing point according to the position of the moving plate 2, realizing the position adjustment and fixing of the guide rod 8 on the bed body 1. The vertical block 54 and the second bolt 55 further lock the second fixing block 10 of the moving plate 2, forming a double-locking structure to ensure that the moving plate 2 is stable and does not shake after adjustment.

[0041] Please refer to Figure 1 and Figure 4 In this embodiment, the fixing mechanism 7 includes a first fixing block 71 and a third bolt 72; a first fixing block 71 is fixedly connected to the lower part of one end of the L-shaped block 61 close to the center of the bed body 1, and a third bolt 72 is threadedly installed at the lower end of the first fixing block 71. The upper end of the third bolt 72 passes through the first fixing block 71 and is threadedly installed on the inner wall of the thread groove 51. The fixing mechanism 7 utilizes the existing thread groove 51 at the lower end of the bed body 1, and directly fixes the first fixing block 71 of the L-shaped block 61 to the bed body 1 through the third bolt 72, realizing the quick disassembly, assembly and positioning of the constraint mechanism 6 and the bed body 1. At the same time, by virtue of the row distribution of the thread grooves 51, the fixing position of the L-shaped block 61 on the guide rod 8 can be flexibly adjusted, improving the adjustability of the constraint position.

[0042] Please refer to Figure 1 and Figure 2 In this embodiment, handrails are fixedly connected to the upper end of the moving plate 2 near both side edges. The handrails are in an inverted U shape, and the inverted U-shaped handrails provide a stable grasping part for the child, especially suitable for children with poor cooperation ability, which can effectively reduce the intraoperative body position deviation and enhance the child's sense of security.

[0043] Embodiment 2: Please refer to Figure 3 On the basis of Embodiment 1, the present application provides a technical solution: the limiting mechanism includes a limiting rod 14 and a threaded sleeve 15; a third groove body 12 is penetrated and opened in the middle of the upper end of the bed body 1. A limiting rod 14 is fixedly connected to the right end of the inner wall of the third groove body 12. A threaded sleeve 15 is threadedly installed on the outer wall of the left end of the limiting rod 14. A slider 9 is fixedly connected to the lower end of the moving plate 2. The slider 9 is sleeved on the side wall of the limiting rod 14. The two sides of the slider 9 are in contact with the two side surfaces of the inner wall of the limiting rod 14. The cooperation between the limiting rod 14 and the slider 9 provides precise sliding guidance for the moving plate 2, ensuring that the moving plate 2 moves smoothly along the axial direction of the bed body 1 and avoiding deviation. The threaded sleeve 15 can be rotated to press against the slider 9 to prevent the slider 9 from sliding out of the side wall of the limiting rod 14.

[0044] Please refer to Figure 1 and Figure 3 In this embodiment, a threaded rod 13 is fixedly connected to the left end of the inner wall of the third groove body 12. The threaded rod 13 is adapted to the threaded sleeve 15. The distance between the mutually close ends of the threaded rod 13 and the limiting rod 14 is greater than the length of the slider 9. The threaded rod 13 is adapted to the threaded sleeve 15. When it is necessary to remove the slider 9 from the side wall of the limiting rod 14, after removing the threaded sleeve 15 from the outer wall of the left end of the limiting rod 14, it can be first installed on the threaded rod 13.

[0045] Please refer to Figure 1 and Figure 3, in this embodiment, a second groove 11 is penetrated and opened on one side of the bed body 1. The second groove 11 communicates with the third groove 12. The width of the second groove 11 is greater than the length of the slider 9, which facilitates the operator to move the slider 9 outwards from the inner wall of the second groove 11.

[0046] Working principle: During use, first place the patient flat on the upper end of the bed body 1. According to the patient's body type and surgical requirements, push the moving plate 2 to slide along the upper end of the bed body 1. The slider 9 at the lower end of the moving plate 2 is sleeved on the side wall of the limiting rod 14 and moves along its axial direction. The limiting rod 14 fits with both side surfaces of the slider 9 to ensure stable movement. When the moving plate 2 moves to a suitable position, the second bolt 55 of the locking mechanism 5 passes through the vertical block 54 and is threadedly installed in the screw holes of the second fixing blocks 10 on both sides of the moving plate 2 to fix the moving plate 2;

[0047] Then, pass the first bolt 53 through the sleeve block 52 and threadedly install it on the inner wall of the screw groove 51 to fix the sleeve block 52 on the bed body 1;

[0048] Next, turn on the electric cylinder 3. The telescopic output shaft of the electric cylinder 3 drives the backrest 4 to rotate around its hinge point with the moving plate 2, and adjusts the backrest 4 to a suitable angle to provide support for the patient's back or legs;

[0049] Subsequently, adjust the restraint mechanism 6. Slide the L-shaped block 61 axially along the guide rod 8, and move the L-shaped block 61 to the limb area (such as upper limb, torso, lower limb) where the patient needs to be restrained. One end of the first restraint belt 66 is sleeved on the side wall of the L-shaped block 61 through the fixing column 65, and the other end passes through the first groove 63 in the middle of one side of the L-shaped block 61 and extends to the outside of another L-shaped block 61. Bond the first hook surface 69 on the lower surface of the other end of the first restraint belt 66 to the first loop surface 62 at the end of another L-shaped block 61 away from the bed body 1 to form a restraint loop around the limb. At the same time, bond the second hook surface 68 at the lower end of the second restraint belt 67 to the second loop surface 16 on the upper end of the bed body 1 to fix the lower end of the restraint belt;

[0050] After the restraint position is adjusted, pass the third bolt 72 of the fixing mechanism 7 through the first fixing block 71 and threadedly install it in the screw groove 51 at the lower end of the bed body 1 to lock the L-shaped block 61 at the specified position on the guide rod 8;

[0051] During the operation, if it is necessary to remove or install the slider 9, the threaded sleeve 15 can be removed from the outer wall of the left end of the limiting rod 14 and installed on the threaded rod 13, and the slider 9 can be directly moved out through the second groove 11;

[0052] During use, the patient can hold the inverted U-shaped handrails on both sides of the upper end of the moving plate 2 to enhance the intraoperative body position stability.
