Patent ID: 11052453

Abstract:
A riveting tool chuck. The riveting tool chuck comprises a cylinder handgrip (1). A rotating member (2) and a transmission member (3) are disposed in the cylinder handgrip in a penetrating manner, the rotating member is axially positioned and circumferentially and rotatably connected to the cylinder handgrip, and the transmission member is circumferentially positioned and axially and movably connected to the cylinder handgrip, and the rotating member and the transmission member are connected by means of a thread structure (4). A safety valve mechanism (9) that can enable the thread structure to have a screw pair pretightening force is disposed between claw body top columns (8) and the transmission member, and in the process of forward rotation of the rotating member, the safety valve mechanism can enable the rotating member to implement screw pair transformation of a screw structure before the axial reaction force between the front end of each claw body (5) and the rear end of a cylinder guiding nozzle (7) is reduced to zero, so that backlash stroke of the screw structure is avoided. A riveting tool using the riveting tool chuck. The riveting tool chuck has the advantages that the structural design is reasonable, and the riveting tool chuck can be adaptive to a driving device containing power output, can provide a pretightening force for screw pairs, and has no backlash stroke.
