Manual turnover device

The utility model provides a manual turnover device. The manual turnover device comprises a rack, a lifting supporting table, a manual lifting driving mechanism, a hand-cranking horizontal lead screw mechanism, a propelling mechanism and a turnover supporting frame. The manual lifting driving mechanism drives the lifting supporting table to move up and down along the vertical structural frame; the hand-cranking horizontal lead screw mechanism drives the propelling mechanism to push the overturning supporting frame to swing to a certain angle. By the adoption of the technical scheme, moving is convenient, and the application range is wide. After a workpiece is placed on the supporting frame, a single person only needs to manually operate the manual lifting driving mechanism and the hand-cranking horizontal lead screw mechanism, overturning of the workpiece can be completed, and operation on the bottom of the workpiece is facilitated. The labor intensity of workers is reduced, and the safety coefficient is high
