Description

Technical Field

[0001] The utility model relates to a multifunctional mechanical jack, belonging to the technical field of mechanical jacks. Background Art

[0002] A screw jack, also known as a mechanical jack, is powered by a screw pair, with a screw or nut sleeve serving as the lifting element. Conventional screw jacks rely on the self-locking action of the threads to support the load. While simple in construction, they suffer from low transmission efficiency and slow return travel. Self-lowering screw jacks, on the other hand, lack self-locking threads and are equipped with a brake. Releasing the brake allows the load to quickly and automatically descend, shortening the return travel time.

[0003] However, the existing mechanical jack has a relatively single function, and it is not convenient to combine the duckbill pliers with the jack. It only has a single supporting function and does not have the function of spreading the object. Utility Model Content
