Primary and secondary shaft-receiving and locking members have respective first and second through-holes therein for receipt of the overhead guide shaft. A spring-receipt member is fixed to the primary shaft-receiving member for cooperation with a spring that tilts the primary shaft-receiving member into a locking position.
