Four groups of handrail structures 2 are used to connect the upper end position of the four stands 1. The support structure 3 is used to connect the bottom end position of the four stands 1. The connection between the four groups of handrail structures 2 and the stands 1 is a rotating connection, and the middle position of each group of handrail structures 2 can also be bent to rotate at an angle. The connection between the support structure 3 and the stand 1 is also a rotating connection, but the rotating connection between the support structure 3 and the stand 1 is limited by the locking structure 4. Only when the locking structure 4 is opened and limited, the support structure 3 can rotate on the stand 1. Under such settings, the bed frame can realize the overall shrinking function. When shrinking, only need to rotate the locking structure 4 upward on the support structure 3 and pull the locking structure 4 upward to realize unlocking and drive the support structure 3 to move upward between the four stands 1. The support structure 3 and the four connection points adopt a rotating connection, so when the support structure 3 moves upward, the four stands 1 will gather towards the middle position. In this process, the four groups of handrail structures 2 will be squeezed by the shrinking of the four stands 1 to bend along the middle position, until the four stands 1 are gathered, the four groups of handrail structures 2 and the support structure 3 will be covered between the four stands 1.
