Abstract: A method for assembling captive screw includes the steps of providing an annular base and positioning an annular washer on a top of the annular base; providing a screw, a coil spring, and a sleeve; downward passing the screw through the coil spring and a top opening of the sleeve; and threading a threaded section of the screw through the annular washer, so that the annular washer is fitted around a shank of the screw to locate below the top opening of the sleeve and above the threaded section of the screw. An inner circumferential edge of the annular washer is not worn away by the threaded section of the screw threaded therethrough, enabling the annular washer to keep a small inner diameter for tightly fitting around the shank of the screw and ensuring reliable assembling of the sleeve to the screw.

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.

Abstract translation: 一种改进的锁定装置包括：具有设置在套圈中心的通孔的套圈和设置在通孔的外周周围的槽; 具有施力部分的锁定单元和穿过通孔的螺杆; 套在所述螺杆上的弹性元件，并且所述弹性元件的端部设置在所述套圈周围的凹槽中，并且所述弹性元件的另一端压靠所述力施加部分的表面; 以及固定到力施加部分上并可移动地联接到套圈的旋钮。 因此，弹性元件可以固定在套圈和锁定单元之间，并被旋钮盖住，以防止弹性元件被外力损坏或被外部物体倾斜，以实现使用弹性元件的更好的稳定性。
