Clamping type supporting and fixing mechanism for connecting end of polyethylene winding pipe

The invention discloses a clamping type supporting and fixing mechanism for the connecting end of a polyethylene winding pipe. The clamping type supporting and fixing mechanism comprises a bottom supporting frame of a triangular structure and a longitudinal adjusting lead screw welded and fixed to the vertex angle position of the upper surface of the bottom supporting frame. The longitudinal adjusting lead screw connected with an internal thread lifting ring is welded to the vertex angle position of the upper surface of the bottom supporting frame, and a left supporting seat, a right front supporting seat and a right back supporting seat which are used for supporting and fixing a winding pipe opening and the lower wall of the winding pipe are assembled through a movable connecting ring atthe top of the internal thread lifting ring, so that the winding pipe is placed and mounted more stably; and meanwhile, the ground clearance can be adjusted as required, operation and use are easy andconvenient, and the appli
