[0035] Refer to Figure 2 , Figure 3 , Figure 5, the rotating shaft 33 penetrates and is rotatably connected to the rear surface of the support plate 2, and the support plate 2 provides support for the rotating shaft 33. A notch is provided on the lower surface of the guardrail 5, and the top end of the electric telescopic rod 72 is inserted into the inner wall of the notch. A limiting groove 701 is provided at the rear end of the upper surface of the guard plate 74. Two groups of limiting grooves 701 are provided, which are symmetrically distributed front and back with respect to the center line of the guard plate 74. The lower surface of the limiting block 76 is square and can be aligned with the limiting groove 701 again every 90-degree rotation. The limiting block 76 is inserted into the inner wall of the limiting groove 701, which can limit the guard plate 74. One end of the connecting spring 77 is fixedly connected to the inner wall of the top end of the connecting block 75, and the other end of the connecting spring 77 is fixedly connected to the upper surface of the limiting block 76. When the limiting block 76 moves upward, it will squeeze the connecting spring 77 to generate a reaction force. The limiting block 76 is slidably connected to the inner wall of the connecting block 75. The dial block 78 penetrates and is slidably connected to the right surface of the connecting block 75 and slides longitudinally.

[0036] Refer to Figure 1 , Figure 3 , the fixing component includes a clamping groove 601. A clamping block 62 is elastically connected to the inner wall of the connecting plate 4 through a compression spring 61. Multiple groups of clamping grooves 601, clamping blocks 62 and compression springs 61 are provided, which are symmetrically distributed front and back with respect to the center line of the guardrail 5. The clamping groove 601 is provided on the rear surface of the fixing plate 71. The clamping block 62 penetrates and is slidably connected to the front surface of the connecting plate 4. One end of the compression spring 61 is fixedly connected to the rear surface of the clamping block 62, and the other end of the compression spring 61 is fixedly connected to the inner wall at the rear side of the connecting plate 4. When the clamping block 62 moves backward, it will squeeze the compression spring 61 to generate a reaction force. The clamping block 62 is inserted into the inner wall of the clamping groove 601. When the clamping block 62 moves backward, it will also disengage from the clamping groove 601 to release the limit. The right surface of the clamping block 62 is provided with an inclined surface. When the inclined surface of the clamping block 62 is squeezed, the clamping block 62 will move backward.

[0037] Working principle: When a patient needs to get out of bed, the medical staff can rotate the worm 31 to drive the worm gear 32 to rotate. The rotating worm gear 32 will drive the rotating shaft 33, the connecting plate 4, the guardrail 5, the fixing component and the protection component to rotate. When it rotates 180 degrees, release the worm 31. At this time, the guardrail 5 will be lowered to remove the blockage of the patient's getting out of bed path. At this time, the medical staff can move the electric telescopic rod 72 to the right. The electric telescopic rod 72 will drive the fixing plate 71 and the handle 73 to move to the right. At this time, when the fixing plate 71 moves to the right, it will squeeze the inclined surface of the clamping block 62, and the clamping block 62 will retract into the connecting plate 4 to release the limit. At this time, the electric telescopic rod 72, the fixing plate 71 and the handle 73 will be disassembled.

[0038] Then the medical staff can align the fixed plate 71, the electric telescopic rod 72, and the handle 73, and push the push block 78 upward to drive the limit block 76 to move upward. The limit block 76 moving upward will squeeze the connecting spring 77 to generate a reaction force and will disengage from the limit groove 701 to release the limit on the protective plate 74. Then the handle 73 can be rotated ninety degrees, and the limit block 76 will be aligned with the limit groove 701 again. The reaction force of the connecting spring 77 will push the limit block 76 to move downward and plug into the limit groove 701 to form a limit. The handle 73, the protective plate 74 and the fixed plate 71 will be opened to form a U shape.

[0039] It is convenient for patients to practice walking by holding the handle 73, and the electric telescopic rod 72 can be extended and retracted so that the height of the handle 73 can be suitable for people of different heights. After the practice is completed, the dial block 78 can be pushed upward to drive the limit block 76 to move upward and disengage the limit groove 701 to release the limit and squeeze the connecting spring 77 to generate a reaction force. Then, after the handle 73 is reversed to the initial position, the limit block 76 will be aligned with the limit groove 701. Under the influence of the reaction force of the connecting spring 77, the limit block 76 will be plugged into the limit groove 701 to form a limit.

[0040] Then the patient lies on the nursing bed 1, and the medical staff rotates the worm 31 in the opposite direction to drive the worm wheel 32 and the rotating shaft 33 to rotate in the opposite direction. When the connecting plate 4 and the guardrail 5 return to their initial positions, they stop rotating. At this time, the guardrail 5 can protect the patient. Then, the slot 601 on the rear surface of the fixing plate 71 is aligned with the block 62 and moves to the left. The fixing plate 71 moving to the left will squeeze the inclined surface of the block 62, so that the block 62 moves backward and retracts into the connecting plate 4 to release the limit and squeeze the compression spring 61 to generate a reaction force. At this time, the fixing plate 71 continues to move. When the slot 601 and the block 62 are aligned, the fixing plate 71 cannot continue to move to the left. Under the push of the compression spring 61, the block 62 will be plugged into the slot 601 to form a limit to ensure the stability of the device.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
