Abstract:
1. An adjustable attachment device comprising: a clamping member adapted to securely clamp a tubular member, the clamping member including an engaging portion having a receiving hole; a sleeve securely mounted to the engaging portion of the clamping member, the sleeve including a longitudinal through-hole having an upper end, the longitudinal through-hole further including a spherical upper wall section, the sleeve further including a cutout passing through the upper end of the longitudinal through hole of the sleeve; a ball received in the sleeve, the upper end of the longitudinal through-hole of the sleeve having a diameter smaller than an outer diameter of the ball; a connecting seat including a portion securely coupled to the ball to move therewith, an object being adapted to be mounted to the connecting seat to move therewith; and a resilient member for biasing the ball to press against the spherical upper wall section of the sleeve, thereby retaining the connecting seat in place; wherein the connecting seat is pressable to compress the resilient member and cause the ball to disengage from the spherical upper wall section of the sleeve, allowing the connecting seat to move along the cutout of the sleeve and allowing the connecting seat to turn to a desired orientation relative to the tubular member wherein the engaging portion of the clamping member has an outer threading, and wherein the sleeve has an inner threading for engaging with the outer threading of the clamping member.
