This new invention involves a rapid locking hand knob construct, which is designed to solve the deficient structure design of the existing like products. The fixed threaded sleeve (5) of the rapid locking hand knob contract has an inner groove around its outer diameter that is mated to the rubber sleeve (3); wherein one end of the first tube (1) is connected to inside diameter of one end of the fixed ring (2), and that the fixed ring has a fixed ring groove (202) provided around outside diameter at the end of the fixed ring and an inner conical surface (201) provided around inside diameter at another end of the fixed ring; The tube hole at the end of the second tube (10) is mated to the locking lining (8) and that one end of the locking lining is fabricated with an outer tapered surface (801) that is inserted into the inner tapered surface of the fixed ring. The threaded sleeve hole of the fixed threaded sleeve is secured into the fixed ring groove of the fixed ring by the screw (11). The rotary rubber sleeve (3) drives the movable thread sleeve to move up and down horizontally in the direction of tube fitting, thus achieving the locking and releasing of such hand button mechanism. |
