Preferably, the distance between the metal reinforcement belt loops 3 closest to the end of the socket 1 and the end of the socket 1 is 4cm-5cm. In the process of inserting the spigot portion 2 into the socket portion 1, due to the extrusion effect of the inserted portion, the outer diameter of the root position of the spigot portion 2 becomes large, so that the end of the socket portion 1 is required to have better deformation performance, otherwise, the root of the spigot portion 2 is difficult to insert into the socket portion 1, so that the insertion is not in place, if the metal reinforcing band ring 3 is arranged too close to the end of the socket portion 1, the deformation performance of the end of the socket portion 1 is poor, so that the socket portion 2 is difficult to insert in place, and if the metal reinforcing band ring 3 is arranged too far away from the end of the socket portion 1, when the connecting part bears external load, the metal reinforcing band ring 3 and the end of the socket portion 1 are easy to break at the position between the metal reinforcing band ring 3 and the end of the socket portion 1. Within this size range, the problem that the socket portion 2 is difficult to insert in place due to an excessively small distance and the improvement effect of the external load bearing capability of the joint between the socket portion 1 and the socket portion 2 is poor due to an excessively large distance can be avoided.
