The utility model discloses a special-shaped socket spanner, which relates to the technical field of socket spanners, and comprises a circular truncated cone seat, a cone is fixedly connected to the top of the circular truncated cone seat, a convex
hexagonal prism is fixedly connected to the top of the cone, a hexagonal groove is arranged in the circular truncated cone seat, a clamping seat is arranged in the cone, and the clamping seat is fixedly connected with the convex
hexagonal prism. A hollowed-out hexagonal groove is formed in the protruding
hexagonal prism and communicates with the clamping base, and the hollowed-out hexagonal groove penetrates through the top of the protruding hexagonal
prism and extends to the bottom of the circular truncated cone base. In practical application, the
wrench is combined with a
ratchet handle, the lower six-edge sleeve penetrates through a
skin round hole to be fixed to a part, the vertical
height difference between the
skin and the part is made up for disassembly and
assembly, the step of disassembly and
assembly of adjacent parts is omitted, the labor intensity is reduced, the working efficiency is improved, and the disassembly
operation time is saved.
