| description | The utility model discloses a bolt. The bolt comprises a bolt body comprising a screw part, a regular hexagon bolt head connected with the screw part in an integrated mode, a screw thread section and a smooth section, wherein a regular hexagon blind hole is formed in the thread section in the axial direction of the screw part, an inner cavity is formed in the smooth section in the axial direction of the screw part, the bolt head is provided with a concave cavity, the through hole inner cavity and the concave cavity are communicated to form a containing cavity, a detachable strip-shaped tool is arranged in the containing cavity and comprises a linkage part which is a regular hexagon prism, the screw part and the strip-shaped tool can be in linkage in the circumferential direction, the linkage part is arranged in the blind hole, a spring is arranged between the linkage part and bottom of the blind hole in an abutting mode, the other end, opposite to the spring, of the linkage part is movably hinged to two strip-sped assistance parts, and the length of the strip-shaped assistance parts is greater than the radius of the circumcircle of the regular hexagon of the bolt head. The detachable tools are arranged in the bolt, and the bolt can be screwed and unscrewed under the condition that no disassembly tool is carried. |
