Portable telescopic supporting device

The invention relates to the technical field of supporting moving equipment, in particular to a portable telescopic supporting device which is provided with a base, universal wheels are arranged belowthe base, the upper portions of the universal wheels are connected with the base, and moving of the base is achieved through the universal wheels. The supporting and height adjusting assembly is composed of a lead screw, a nut, a toggle plate, a supporting plate, a rotating disc, a limiting sleeve, a branch pipe and a bracket, the rotating disc drives the branch pipe to rotate so as to drive thelead screw to rotate to achieve vertical movement of the lead screw, and the bracket is arranged at the upper end of the branch pipe. The bottom of the bracket is sleeved at the upper end of the branch pipe through the casing pipe to achieve replaceable and rotatable connection of the bracket. The bracket has the advantages of being simple in structure, convenient to use, labor-saving, efficiency-increasing, space-saving a
