The U-shaped rod is movably installed in the middle of the lower end of the storage box, and square rods are symmetrically arranged on the cross rod of the U-shaped rod, and transmission gears are symmetrically arranged on both sides of the U-shaped rod; the transmission gear is divided into an upper gear and a lower gear, and the upper gear of the transmission gear on the left side meshes with the rack one of the actuator on the left side, and the lower gear meshes with the output shaft, and the transmission gear on the right side is correspondingly connected to the actuator on the right side; bevel grooves are arranged on both sides of the cylinder at the front end of the control rod, and the bevel grooves are correspondingly connected to the square rods symmetrically arranged on the U-shaped rod. The control rod is divided into three gears, gear one: the transmission gears on the left and right sides of the adjusting mechanism are suspended and not meshed with the output shaft; gear two: the lower gear of the transmission gear on the left side of the adjusting mechanism meshes with the output shaft, and the transmission gear on the right side is suspended; gear three: the lower gear of the transmission gear on the right side of the adjusting mechanism meshes with the output shaft, and the transmission gear on the left side is suspended.

6. The retractable article placement rack for nursing use according to claim 1, characterized in that: The actuator includes a rack 1 and a transmission gear 1. The transmission gear 1 is divided into an upper gear 1 and a lower gear 1. One end of the rack 1 meshes with the upper gear of the transmission gear, and the other end meshes with the upper gear of the transmission gear 1. The lower transmission gear 1 of the transmission gear 1 meshes with the rack at the lower end of the storage drawer 2. The storage drawers on the left and right sides and the corresponding actuators at the lower ends are symmetrically installed about the middle of the storage box.

7. The retractable article placement rack for nursing use according to claim 1, characterized in that: The follower mechanism includes a threaded sleeve, the internal thread of the threaded sleeve is connected to the screw of the storage drawer one; the lower end of the threaded sleeve is internally rotatably connected to the output shaft, and a keyway is provided on the inner wall of the threaded sleeve. The electromagnet on the output shaft works to press the pin key located inside the keyway of the output shaft against the keyway of the threaded sleeve, and the synchronous rotation of the output shaft and the threaded sleeve is locked by the pin key. The threaded sleeve rotates with the output shaft, driving the screw to move up and down inside the threaded sleeve, thereby controlling the taking and placing of the storage drawer one.
