ABSTRACT:
A manual control device includes an actuated tube which is connected to the stem member contacting against the rod movably received in the plug of the pickproof lock, an operating member securely connected to the actuating tube by receiving the boss thereof in the groove defined in the actuating tube, wherein the operating member has a rib so as to be frictionally received in the actuating tube. Both of the actuating tube and the operating member are received in the sleeve which has an L-shaped groove into which the protrusion extending from the actuating tube is movably received. The stem member pushes the rod of the pickproof lock by pushing the combination of the actuating tube and the operation member and rotating the combination to let the protrusion be securely positioned in the L-shaped groove of the sleeve.
