When the patient needs to rest, the support plate 10 can be rotated so that the card block 11 squeezes the locking core 7, and the locking core 7 will be retracted when it is retracted. The movable ring 9 is driven to squeeze the spring 8. When the inclined surface of the block 11 is completely offset from the inclined surface of the locking cylinder 7, the elastic force of the spring 8 will push the movable ring 9 and drive the locking cylinder 7 to restrict the block 11. In this way, the support plate 10 and the connecting plate 5 will be folded and fitted together. Then the connecting plate 5 will be erected, the movable rod 13 will be pushed and the two sliding columns 14 will be driven to be inserted into the corresponding limiting holes 18, so that the folded bicycle is in a vertical state and fixed, so that it will not affect the patient's leg activities and can take a short rest better.

[0036] Working principle: When the bed bicycle is needed, the nurse or family member can grab the bicycle hanging on the side of the bed frame 2 and rotate it around the bed frame 2. At this time, the connecting plate 5 and the supporting plate 10 are fitted together, and the pull ring can be pulled to drive the locking cylinder 7 to move. When the locking cylinder 7 is completely separated from the outer side of the card block 11, the card block 11 can be pulled out from the inside of the connecting plate 5, and then the supporting plate 10 is separated from the connecting plate 5, and the supporting plate 10 can be rotated, and the elastic clip 16 can be clamped on the outer side of the fixing column 19, so that the bicycle can be used normally. When the patient needs to rest, the supporting plate 10 can be The locking plate 10 is rotated to make the block 11 squeeze the locking cylinder 7. At the same time, the locking cylinder 7 will drive the movable ring 9 to squeeze the spring 8 when it shrinks. When the inclined surface of the block 11 is completely offset from the inclined surface of the locking cylinder 7, the elastic force of the spring 8 will push the movable ring 9 and drive the locking cylinder 7 to restrict the block 11. In this way, the support plate 10 and the connecting plate 5 will be folded and fitted together. Then the connecting plate 5 will be erected, the movable rod 13 will be pushed and the two sliding columns 14 will be driven to be inserted into the corresponding limiting holes 18, so that the folded bicycle is in a vertical state and fixed, so that it will not affect the patient's leg activities and can take a short rest better.
