The locking disk has defined grooves arranged side by side. Arranged between the locking spring and the locking disk is a ball and a locking slider which is provided with a recess. The ball is positioned in the recess of the locking slider and is movable into and out of engagement with the grooves of the locking disk through a sliding motion of the locking slider.
