[0002] A workpiece is a product component in the manufacturing process, also known as a workpiece, a workpiece, a hardware part, etc. During processing, such as grinding, galvanizing, etc., it is necessary to use lifting tools to move the workpiece from one place to another to facilitate subsequent processing.

[0003] Some workpieces are galvanized on their surfaces during processing to improve their corrosion resistance and other properties. Currently, when galvanizing workpieces, multiple workpieces are hung on a hanging rack, and the hanging rack is used to immerse the workpieces in molten zinc liquid for galvanizing.

[0004] When the workpiece is hung on a hoisting frame for galvanizing, there will be a certain contact area between the workpiece and the hoisting frame. These contact points are easily shielded or blocked by the hoisting parts, making it difficult for the zinc liquid to fully contact these areas, resulting in incomplete or missing galvanizing in these areas.

[0013] Beneficial effects of the utility model:

[0014] 1. The utility model provides a workpiece lifting tool. When galvanizing, the workpiece is suspended on the hanger through the hanger and immersed in molten zinc liquid. When the galvanizing of other areas of the workpiece is completed, the electric push rod is started to raise the second hanger, and then the push plate is pushed up through the connecting rod. At this time, the push plate pushes and supports the bottom of the workpiece. As the push plate rises, the upper end of the workpiece will gradually break away from the hanger, so that the contact area between the workpiece and the hanger can also be covered and galvanized by the zinc liquid, so as to improve the comprehensiveness of the galvanizing of the workpiece and thus improve the quality of galvanizing.

[0015] 2. The utility model provides a workpiece lifting tool, which is achieved by fully rotating the threaded sleeve to the outer wall of the first screw. At this time, the first screw and the second screw are completely disengaged, so that a suitable push plate can be replaced according to the size and model of the workpiece. For example, when it is necessary to process workpieces of different sizes or shapes, the operator can quickly remove the current push plate and install a push plate suitable for the new workpiece to improve the adaptability and flexibility of the device. The cooperation between the plug block and the slot further increases the firmness of the connection between the two and quickly positions the angle of the push plate.
