[0002] In automated production, automatic lifting mechanisms are often used when unloading materials in order to improve production efficiency.

[0003] For example, Chinese patent CN220467454U proposes an automatic lifting mechanism, including a frame, a driving motor, a reducer, a crank rocker mechanism and a linear sliding mechanism; the driving motor and the reducer are fixed to the bottom of the frame, and the crank rocker mechanism is installed at both ends of the output shaft of the reducer; the crank rocker mechanism is docked with one end of the linear sliding mechanism, and the crank rocker mechanism is used to push the linear sliding mechanism up and down; the linear sliding mechanism is installed below the top of the frame, and the other end of the linear sliding mechanism is fixedly connected to the tray; the tray is located on the top of the frame. The driving motor transmits the transmission to the reducer, and the crank rocker mechanism pushes the linear sliding structure to realize linear lifting and lowering motion.

[0004] However, the above patent is not applicable to situations where the items to be lifted are heavier; in addition, the above patent requires higher accuracy during lifting, and the fault tolerance rate needs to be improved.

[0005] Based on this, the utility model designs a wedge-shaped lifting mechanism with universal floating to solve the above problems. Utility Model Content
