ABSTRACT:
A stabilizer including a female ring installed on a female tube of the telescopic stand and a male ring installed on a male tube of a telescopic stand. The male ring is put in the female ring and a hole is set on each of two outwardly projecting parallel walls. Inside one of the holes of the female ring is a toothed block which is engageable with another toothed block of a handle so that the tightness and relaxation of the stabilizer is determined by rotating the handle to engage or disengage the two toothed blocks. The male ring further has an opening between the two holes of the male ring in which a spring is set to provide the male ring with a better restoring force.
