Abstract:
1. A universal support, comprising: a brace unit; a mounting unit, disposed on a top end of the brace unit; and a connecting unit, disposed on a bottom end of the brace unit; wherein the brace unit comprises: a first tube assembly, comprising a first inner tube and a first outer tube, the first inner tube being telescopically received in the first outer tube, around an outer surface of the first outer tube disposed a first quick-release clamp unit, and a top end of the first inner tube connecting to the mounting unit; a second tube assembly, comprising a second inner tube and a second outer tube, the second inner tube being telescopically received in the second outer tube, around an outer surface of the second outer tube disposed a second quick-release clamp unit; a third tube assembly, a bottom end thereof connecting to the connecting unit; a first joint assembly, pivoted between the first and the second tube assemblies; and a second joint assembly, pivoted between the second and the third tube assemblies; wherein the first quick-release clamp unit comprises: a first clamping tube, comprising a first end and a second end, the first end being fastened to the first outer tube, and the second end receiving the first inner tube, on the second end axially disposed a vertical slot, on the first clamping tube radially disposed a horizontal slot at an extending angle of 180°±5°, and the horizontal slot communicating with the vertical slot; a pair of first ears, protruding on both sides of the vertical slot; and a first quick-release clamp assembly, piercing through the first ears; wherein the second quick-release clamp unit comprises: a second clamping tube, comprising a third end and a fourth end, the third end being fastened to the second outer tube, and the fourth end receiving the second inner tube, on the fourth end axially disposed a vertical slot, on the second clamping tube radially disposed a horizontal slot at an extending angle of 180°±5°, and the horizontal slot communicating with the vertical slot; a pair of second ears, protruding on both sides of the vertical slot; and a second quick-release clamp assembly, piercing through the second ears; wherein the connecting unit comprises: a fastening base, fastening to a bottom end of the third tube assembly, and a bottom of the fastening base having a first through hole; a connecting plate, one end thereof disposed a connecting member, and another end thereof disposed a second through hole; a supporting plate, on both ends thereof disposed a pivoting hole and a third through hole respectively; a bolt, piercing through the first through hole, the second through hole and the pivoting hole, a bottom end of the bolt mounting a nut; and a supporting member, comprising a first screw and a socket head, the first screw being elevatably fastened to the third through hole, on a bottom end of the first screw disposed a ball head covered by the socket head, and the socket head being universally rotatable with respect to the ball head; wherein the first joint assembly comprises: a first adjusting member, one end thereof connecting to a end of the first outer tube away from the first quick-release clamp unit, another end thereof being disposed a first adjusting part formed in a substantially semi-spherical shape, in a center axis of the first adjusting part disposed a first engaging hole with a non-circular profile, on an inner surface of the first adjusting part disposed a first tooth plate; a second adjusting member, one end thereof connecting to a end of the second inner tube away from the second outer tube, another end thereof being disposed a second adjusting part, corresponding to the first adjusting part, formed in a substantially semi-spherical shape, in a center axis of the second adjusting part disposed a first positioning hole, and the first positioning hole having a same axis as the first engaging hole, on an inner surface of the second adjusting part disposed a second tooth plate; and a first positioning member, piercing through the first engaging hole and the first positioning hole to adjust a relative distance of the first and the second adjusting members, selectively engaging the first tooth plate with the second tooth plate or disengaging the first tooth plate from the second tooth plate, and when the first tooth plate disengaging from the second tooth plate, the first and the second adjusting members being rotatable with respect to each other; wherein the second joint assembly comprises: a third adjusting member, one end thereof connecting to a end of the second outer tube away from the second quick-release clamp unit, another end thereof being disposed a third adjusting part formed in a substantially semi-spherical shape, in a center axis of the third adjusting part disposed a second engaging hole with a non-circular profile, on an inner surface of the third adjusting part disposed a third tooth plate; a fourth adjusting member, one end thereof connecting to a end of the third tube assembly away from the connecting unit, another end thereof being disposed a fourth adjusting part, corresponding to the third adjusting part, formed in a substantially semi-spherical shape, in a center axis of the fourth adjusting part disposed a second positioning hole, and the second positioning hole having a same axis as the second engaging hole, on an inner surface of the fourth adjusting part disposed a fourth tooth plate; and a second positioning member, piercing through the second engaging hole and the second positioning hole to adjust a relative distance of the third and the fourth adjusting members, selectively engaging the third tooth plate with the fourth tooth plate or disengaging the third tooth plate from the fourth tooth plate, and when the third tooth plate disengaging from the fourth tooth plate, the third and the fourth adjusting members being rotatable with respect to each other.
