ABSTRACT:
A telescopic stick includes a retaining mount, a supporting sleeve, an inner tube, and an outer tube wherein the retaining mount has a base disposed at one side thereof, a step-wise through hole disposed at the center of the base thereof, a resilient stop block protruding at the upper surface of the base thereof, and a half-tubular abutment plate extending outwards at the lower surface of the base thereof. The supporting sleeve has a circular registration recess defined by an engagement ring and an abutment face of the same diameter at both sides thereof respectively, and a sleeve column with axial flexible ribs distributed thereon to be adapted at the corresponding outer side of the inner and outer tubes therein respectively. In practical use, the inner and outer tubes in sleeve registration are adjusted of length in horizontal direction, and the supporting sleeve is attached to the retaining mount with the resilient stop block abutted tightly against the supporting sleeve for secure location thereon, preventing the inner and outer tubes from coming off there-from when pushed or pulled by outer force.
