ABSTRACT:
A driving unit which can transmit torque to one end portion of a driven part, such as mandrel or a spindle for convoluted textile or other material, has a rotary driving member one end portion of which has a socket for the one end portion of the driven part and carries a wheel-shaped confining member which is pivotable on the driving member between an operative position in which it prevents removal of the end portion of the driven part and an inoperative position in which the end portion of a driven part can be inserted into or removed from the socket. The confining member is pivotable by a toggle joint which is partially recessed into the driving and/or confining member and is actuatable by a motor and a spring. The spring biases the links of the joint to positions in which the confining member assumes the operative position, and the motor can be actuated to pivot the links in a direction to move the confining member to the inoperative position. The action of the motor upon the links of the toggle joint can be assisted by an attendant who pushes or pulls the confining member to its inoperative position.
