Abstract
An improved lock device includes: a ferrule having a through hole disposed at the center of the ferrule, and a groove disposed around the external periphery of the through hole; a locking unit having a force exerted portion and a screw rod that passes through the through hole; a resilient element sheathed onto the screw rod, and an end of the resilient element being disposed in a groove around the ferrule, and another end of the resilient element pressing against a surface of the force exerted portion; and a knob fixed onto the force exerted portion and movably coupled to the ferrule. Therefore, the resilient element can be fixed between the ferrule and the locking unit, and covered with the knob for preventing the resilient element from being damaged by external forces or tilted by external objects to achieve a better stability of using the resilient element.
