Supporting device with quick positioning function

The utility model relates to the technical field of pipeline installation, and discloses a supporting device with a quick positioning function, which comprises a base, a U-shaped frame is fixedly installed on the upper surface of the base, two groups of through holes are formed in the U-shaped frame, rubber belts are attached to the inner walls of the through holes, and the rubber belts are fixed on the base. According to the supporting device with the rapid positioning function, when a pipeline needs to be clamped and positioned, the pipeline is firstly placed between a U-shaped frame and a rubber belt, then a push rod is pushed towards the inner wall of the base, meanwhile, a connecting rod and a limiting rod are matched, and the limiting rod can enable a rotating rod to be separated from limiting; the two sets of rotating rods can rotate in the opposite directions through cooperation of the disc and the elasticity of the clockwork spring, and the rubber belt is wound on the outer walls of the two sets of r
