description The sleeve head structure comprises a sleeve head body and at least two stages of nut positioning holes which are sequentially and inwards distributed from one end of the sleeve head body in the axial direction of the sleeve head body, the sizes and specifications of all the stages of nut positioning holes are different, and a vertical line between the vertex of each nut positioning hole and the axis of the sleeve head body is a vertex radial line. And the vertex radial line of any stage of nut positioning hole and the vertex radial line of the other at least one stage of nut positioning hole are staggered on the axial projection of the sleeve head body. Generally, the vertex position of the nut positioning hole is the thinnest position of the sleeve head wall, and the vertexes of the nut positioning hole are staggered, so that the weak part of the sleeve head wall can be prevented from being excessively concentrated, the stress strength of the sleeve head is improved, and the service life of the sleeve is pr
