Rotary pressing mechanical structure

The utility model discloses a rotary pressing mechanical structure which comprises a fixing pin, an upper cover, an upper lifting block, a pressing block, a base, a compression spring, an equal-height screw and a limiting block. The device is reasonable in structural design; practicality is high, during work, the fixing pin mainly serves as a handle; convenient manipulation, the lifting block is driven to lift through the fixing pin; the lifting stroke of the lifting block is limited by the equal-height screw and the compression spring; the pressing block is driven to the position above an object to be pressed, under the condition of no external force, the compression spring can press the upper lifting block downwards, when the upper lifting block drives the limiting block to be clamped in the first notch, the pressing state is achieved, when the upper lifting block drives the limiting block to be clamped in the second notch, the opening state is achieved, and the device is manual, low in cost, simple in stru
