The invention discloses a pressing-hand assembly with a limiting function and for a jack. A limiting protrusion is added and arranged on a locating pin, and a pressing-hand body is provided with a limiting part which is matched with the pressing-hand body, so that the locating pin and the pressing-hand body are axially fixed. In this way, it is ensured that the locating pin and the pressing-hand body are connected, and meanwhile locking and detaching between the locating pin and a handle can be achieved by axially moving and rotating the locating pin, and the rotation angle is smaller than 180 degrees. The pressing-hand assembly with the limiting function and for the jack is simple in structure and reasonable in design. A worker only needs to move and rotate the locating pin in the axial direction to clamp and fix the handle to a limiting groove or detach the handle from the limiting groove. In this way, the handle can be easily fixed in the pressing-hand body or pulled out from the pressing-hand body, and a pressing-hand bolt does not need to be screwed manually. Operation is simple and labor is saved. The efficiency is high, and the structure is reasonable. The motion reliability is high so that use safety can be ensured. Meanwhile, machining is simple, and the cost is low.
