A die adjusting device of a press machine comprises a plunger type cylinder, a guide column, a nut lifting driving mechanism, an adjusting nut, a fixing seat and an upper cross beam. The lower ends of the guide columns are fixed to the base, and the upper ends of the guide columns penetrate through and extend out of the upper beam which is in sliding fit with the guide columns. A cylinder body of the plunger type cylinder is fixed to the fixing base, the fixing base is installed on the upper cross beam, and a plunger of the plunger type cylinder is arranged at the upper end of the guide column. The adjusting nut is sleeved outside the guide post in a penetrating manner, is in threaded connection with the guide post, is positioned above the upper cross beam and in the fixed seat, and is driven by the nut lifting driving mechanism to ascend or descend along the guide post; and the nut lifting driving mechanism is mounted on the upper cross beam. The die adjusting device of the press machine is simple in structure, simple in die adjusting and high in die adjusting precision.

The application discloses a handle structure with a spiral curved surface lock, which is used for locking a plug and a socket of a fluid connector, a handle accessory of the handle structure is connected to the plug through a shaft pin, the handle accessory comprises a locking part, a spiral curved surface for guiding a locking column on the socket is arranged on the locking part, and a locking groove for fixing the locking column is arranged on the locking part, the locking groove is connected with the spiral curved surface, a convex part is arranged at a position where the spiral curved surface transitions to the locking groove, and the locking column is connected to the locking part from the bottom to the top of the handle structure; the force applying mode from the bottom to the top of the application overcomes the self-locking in the connecting process of the existing structure, thereby overcoming the defect that the connection is stuck; the structure that the inflection point is added in the locking groove ensures the locking, prevents the self-unlocking phenomenon from occurring in the use process, and overcomes the defect that the locking shakes through the limiting structure.
