The gap between the outer side wall of bushing 1 and the inner side wall of upper steering tube 5 realizes the tight connection between bushing 1 and upper steering tube 5, so that upper steering tube 5 can effectively control the rotation of lower steering tube 6, increasing the upper Steering tube 5 and the lower steering tube 6 rotate smoothly; when installing, after fitting the limiting end on the outer wall of the bushing 1, insert the bushing 1 with the limiting part 2 into the upper steering tube 5, the quick sleeve installation between the bush 1 and the upper steering tube 5 can be realized, which reduces the difficulty of assembly. At the same time, when there is a deviation in the size of the stopper 2, the deviation can be eliminated by the elastic deformation of the stopper 2 , reducing the processing accuracy requirements of the limiting member 2 and reducing the manufacturing cost.
