The invention discloses an automatic-limiting pressing-hand assembly structure used for a jack. A bearing and an elastic part are added to a locating pin, so that the locating pin and the bearing are axially fixed, and the two ends of the elastic part are connected with the bearing and a pressing-hand body respectively. In this way, it is ensured that the locating pin is connected with the pressing-hand body, and meanwhile a guide slide face of the locating pin is formed only by rotating the locating pin. Therefore, when a handle is inserted into an inserting groove, the locating pin is pushed through the guide slide face to stretch and contract along a through hole, and accordingly locking of the locating pin and a handle clamping groove is achieved. In addition, after use, the guide slide face is rotated by 180 degrees, and the locating pin is pushed through the guide slide face to stretch and contract again, so that the handle is pulled out from the inserting groove. The automatic-limiting pressing-hand assembly structure used for the jack is simple in structure and reasonable in design. A worker only needs to rotate a pin rod to adjust the orientation of the guide slide face, and then 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 the efficiency is high.
