ABSTRACT:
An anchoring fixture for stools capable of adjusting elevation is installed on an axle hub hinged on the top end of tripod legs which rest on the floor. The axle hub has a longitudinal axle hole to hold a screw post fastened to the bottom of a stool. The axle hub has a hinge portion on one side of the top surface. The hinge portion has lugs on two sides to be coupled with one end of two clamping members. The clamping members have another end to be fastened by a fastening element. The hinge portion and the two clamping members have respectively a thread portion which jointly mates and couples with the screw post beneath the stool. Thus the elevation of the stool may be rapidly adjusted upwards and downwards to clamp the screw post tightly.
