Abstract
A rapid locking hand knob construct includes a fixed threaded sleeve having an inner groove around its outer diameter that is mated to a rubber sleeve. One end of a first tube is connected to an inside diameter of one end of a fixed ring. The fixed ring has a groove provided around an outside diameter at an end thereof and an inner conical surface provided around an inside diameter at another end thereof. The tube hole at the end of a second tube is mated to a locking lining, wherein one end thereof includes an outer tapered surface that is inserted into an inner tapered surface of the fixed ring. A hole on the fixed threaded sleeve is secured into the groove of the fixed ring by a screw. A rotary rubber sleeve drives the movable thread sleeve up and down horizontally in the direction of the tube fitting.
