When in use, it not only requires a certain amount of strength and time to crank the handle, the operation is relatively laborious and the adjustment speed is slow. In addition, due to the instability of manpower and the difficulty in maintaining uniform force, an imbalance of force may occur during the adjustment process, causing the bed to shake or jam, affecting the patient.

[0004] Patent document CN205729665U discloses a solid wood medical electric bed, which includes a bed frame and a lifting device. The bed frame is made of wood and comprises a movable plate and a fixed plate. The movable plate is movably connected to the bed frame via a circular rotating shaft and is spliced ​​with the fixed plate. The base of the lifting device is fixedly connected to the fixed plate.
