The working principle of the embodiment is as follows:

telescoping leg extension: the unlocking key is pressed to pull the unlocking pull rod to enable the positioning bayonet lock to be separated from the adjusting bayonet lock, so that the outer support leg can move up and down on the inner support leg, the external force of the unlocking key is removed, the unlocking pull rod is pressed by the second locking spring and the positioning bayonet lock is pressed by the first locking spring, and the positioning bayonet lock is clamped in the corresponding adjusting bayonet lock, so that the movement of the outer support leg on the inner support leg is limited.

Swinging the side frame: and after the external force is removed, the return spring drives the annular unlocking piece to reset and rotate, and the chuck spring pushes the locking chuck to lock the third connecting piece, so that the third connecting piece is limited to rotate relative to the second connecting piece to lock the movement of the side wall frame on the support frame.

Side wall frame armrest cross frame pull-down: the unlocking button is pressed, and the rolling tube automatically rolls the linkage rolling cloth under the action of the pre-tightening torsion spring so as to pull down the armrest cross frame.

The bed leg stretches out and draws back: when the baby crib is fixed at the side of the adult bed by the fixing straps, the unlocking push rod is pushed backwards to unlock the foot locking mechanism and drive the inner foot tube to retract into the outer foot tube, when the baby crib leaves the adult bed, the pushing mechanism automatically pushes the inner foot tube forwards to enable the inner foot tube to automatically extend out of the outer foot tube, and when the inner foot tube moves to a locking position, the foot locking spring automatically pushes the foot locking member to lock the inner foot tube and the outer foot tube, so that the telescopic state of the inner foot tube and the outer foot tube is automatically locked.
