Clamping mechanism and limiting mechanism for lifting device

Abstract

A clamping mechanism for a lifting includes a mounting frame, at least two clamping plates, a vertical column and a linkage structure. Two ends of the mounting frame are each provided with a mounting shaft. The clamping plates are each hinged to the mounting frame via the mounting shaft. The vertical column is vertically arranged on the mounting frame, and is located between the clamping plates. The linkage structure is arranged on the vertical column, and is configured to control the clamping plates in a clamping or releasing state. A limiting mechanism is also provided for the lifting device, including a vertical column, a sliding plate and an elastic component, where the vertical column is provided with a first guide hole and a second limit pin; and the sliding plate is provided with a second guide hole and a first limit pin.
