One end of the extension is equipped with a locking element for adjusting the tilt angle of the body 1, and the other side of the extension is equipped with a safety element for locking the locking element. The safety element can prevent the locking element from coming off under force.

[0015] It should be added that the outer sides of the main body 1 and the extension body 2 are wrapped with cotton material and filled with materials such as sponge and pearl cotton. The main body 1 is U-shaped, and the two extension bodies 2 are located at both ends of the main body 1. The extension bodies 2 and the main body 1 can be used in a prone position, or the main body 1 can be hinged and folded at one end of the extension body 2 through the connector, so that the patient can use it in a sitting or lying position. The locking device can be used to lock and fix the main body 1 after adjusting the folding angle, and the connecting device can be locked and fixed again through the safety device to prevent the main body 1 from being unlocked and flipped after being folded.

[0016] Specifically, the connector includes connecting blocks 3 fixedly connected to both ends of the main body 1, two fixing blocks 4 fixedly connected to the end of the extension body 2, a fixing shaft 5 fixedly connected between the two fixing blocks 4, the fixing shaft 5 passing through the connecting blocks 3 and hinged thereto, and a bending sleeve 18 made of silicone material fitted on the outer side between the extension body 2 and the main body 1.

[0017] The bending sleeve 18 is also filled with sponge and cotton wool. The bending sleeve 18 can bend as the angle of the main body 1 and the extension body 2 changes. The bending sleeve 18 can protect the user from being pinched and improve the user's comfort. The two fixing blocks 4 are fixedly connected to the extension body 2 respectively. The two fixing blocks 4 are located on both sides of the connecting block 3. The connecting block 3 can drive the main body 1 to rotate around the fixed axis 5 so that the operator can adjust the main body 1 to achieve different support angles as needed.

[0018] More specifically, the locking element includes a fixing groove 6 located at the end of the extension body 2 and between two fixing blocks 4. An elastic frame 8 for pushing the sliding plate 7 is fixedly connected to the inside of the fixing groove 6. A rack 9 is fixedly connected to one side of the sliding plate 7. A plurality of teeth 10 arranged in a circle are fixedly connected to the outside of the connecting block 3. The teeth 10 mesh with the rack 9. A plurality of guide rods 16 arranged evenly are fixedly connected to one side of the elastic frame 8. A spring 17 is fitted on the outside of the guide rods 16. The two ends of the spring 17 are fixedly connected to the elastic frame 8 respectively. The ends of the fixing blocks 4 and the rack 9 are both arc-shaped.

[0019] It should be added that the sliding plate 7 is convex, the fixing groove 6 can prevent the sliding plate 7 from falling off and limit its movement, and the tooth 10 has a right trapezoidal cross section so that the fixing block 4 can rotate around the fixing axis 5 in one direction. At the same time, the tooth 10 squeezes and pushes the rack 9. When the rotation stops, multiple springs 17 can squeeze and push the elastic frame 8. The elastic frame 8 can squeeze and push the rack 9 on one side of the sliding plate 7 so that the rack 9 can be embedded in the tooth 10 on the outside of the fixing block 4 to lock and fix the fixing block 4, thereby improving the convenience and stability of the folding and bending body 1.

[0021] Among them, the pull rod 11 can drive the rack 9 on one side of the sliding plate 7 to disengage from the teeth 10, so as to unlock the body 1 and lay it flat. The end of the buckle block 13 is arc-shaped and inserts into the outside of the pull rod 11 to prevent the pull rod 11 from moving in the opposite direction due to the sliding plate 7. The star screw 14 can pass through the buckle block 13 and insert into the locking groove 15 to lock the buckle block 13 to prevent it from disengaging, thereby improving the stability of adjusting the folding angle of the body 1.

[0022] Working principle: First, the main body 1 drives the connecting block 3 to rotate around the fixed shaft 5. At this time, the teeth 10 on the outside of the fixed block 4 press and push the rack 9, so that the rack 9 pushes the elastic frame 8 on one side of the sliding plate 7 into the fixed groove 6. When the rotation stops, multiple springs 17 press and push the elastic frame 8. At the same time, the elastic frame 8 presses and pushes the rack 9 on one side of the sliding plate 7. At this time, the rack 9 is embedded in the teeth 10 on the outside of the fixed block 4 and clamps and fixes the fixed block 4. Then, the buckle block 13 rotates around the mounting shaft 12, so that the buckle block 13 clamps and tightens the pull rod 11. Then, the star screw 14 is screwed into the locking groove 15 on the outside of the buckle block 13 to lock and fix the buckle block 13.
