Polyethylene winding pipe connecting device with telescopic limiting mechanism

The invention discloses a polyethylene winding pipe connecting device with a telescopic limiting mechanism. The polyethylene winding pipe connecting device comprises a polyethylene winding pipe body and a connecting device body installed at the connecting end of the polyethylene winding pipe body. Strip-shaped transmission grooves internally provided with translation racks are formed in the innerside surface of the polyethylene winding pipe body, a lateral threaded connection pipe is screwed into the polyethylene winding pipe body to be in threaded connection with the translation racks, translation of the translation racks is controlled by rotating the lateral threaded connection pipe, and the polyethylene winding pipe body and the connecting device body are fixedly connected by insertingguide rods at the outer side ends of the translation racks into external positioning holes, so that the loading and unloading operation is greatly facilitated, and the mounting modes are more diversified; and meanwhile, a lat
