An automatic mounting appliance for assembling clamp pins, screws, nuts and the like is adapted to be installed on a machine driven into rotation by a motor. The appliance comprises coaxial elements i.e. a holding member for receiving a portion of the pins, screws, or nuts terminated at one end by a socket, a gripping member having angular shift with respect to the holding member and terminated at one end by a socket axially adjacent to the first mentioned socket, both sockets being in coincidence only in one of two end positions, a rotary member driven by the motor, a stationary member, and a driving member radially interposed between the rotary and gripping members to frictionally drive the gripping member from the rotary member, whereby the angular shift permits locking or unlocking of the pins, screws, or nuts depending on the direction of rotation. |
