Among them, the reduction motor 7 provides driving power for the multi-edge rods 6 to ensure the convenient output of power by the 'I'-shaped transmission mechanism, and then acts on the lifting bed foot assembly 4 to ensure the effective realization of the lifting action. Further, a reversing gearbox A8 is provided at the connection and intersection points between multiple multi-edge rods 6, and a reversing gearbox B9 is provided at the end of the multi-edge rods 6 and is in transmission connection with the lifting bed foot assembly 4. The control device 3 is electrically connected to the reduction motor 7 and is used to drive and control the lifting bed foot assembly 4 to drive the bed body 1 and the table body 5 to perform synchronous up and down lifting actions. That is to say: the control device 3 conveniently controls the operation of the reduction motor 7 to ensure the effective output of driving power on the multi-edge rods 6. The multi-edge rods 6 receive the driving power and, under the action of the reversing gearbox A8 and the reversing gearbox B9, act the driving power on the lifting bed foot assembly 4, thereby realizing the free adjustment of the vertical positions of the bed body 1 and the table body 5 to meet different usage requirements;
