Description

Special-shaped stainless steel screw Technical Field The utility model relates to the technical field of stainless steel screws, in particular to a special-shaped stainless steel screw. Background The special-shaped stainless steel screw is a specially designed stainless steel fastener, the special shape of the special-shaped stainless steel screw is different from a standard screw (such as a common hexagon head, a cross groove and the like) in a nonstandard shape or structure, generally, stainless steel such as 304, 316 and the like is adopted, and the special-shaped stainless steel screw has the characteristics of corrosion resistance, high temperature resistance and high strength, and is suitable for a humid or corrosive environment. When the existing special-shaped stainless steel screw is used, the special-shaped groove of the screw head is of a fixed design, different screwdrivers can not be flexibly switched and adapted, if the screwdrivers carried by staff are not matched with the screw groove types, disassembly and assembly operations are difficult to carry out, the working efficiency is affected, and the problem is more remarkable especially in an environment with urgent maintenance or limited tools. Therefore, aiming at the problems that the special-shaped groove of the nail head of the existing special-shaped stainless steel screw is fixedly arranged and can not be flexibly switched, and a worker can not conveniently disassemble and assemble the special-shaped stainless steel screw with a wrong screwdriver, the special-shaped stainless steel screw can be designed. Disclosure of utility model In order to solve the problems that the special-shaped groove of the nail head of the existing special-shaped stainless steel screw is fixedly arranged and can not be flexibly switched, and a worker can not conveniently disassemble and assemble the screw with a wrong screwdriver. The special-shaped stainless steel screw comprises a screw head, a square block, a screw body, a mounting groove, an adjusting mechanism, a square block, a cross notch, a Y-shaped notch, a positioning mechanism and a limiting mechanism, wherein the screw body is fixed at the bottom of the screw head, the mounting groove is formed in the top of the screw head, the adjusting mechanism is connected with the square block and used for driving the square block to rotate, the triangular notch is formed in the top of the square block, the hexagonal notch is formed in the bottom of the square block, the cross notch is formed in the left side of the square block, the Y-shaped notch is formed in the right side of the square block, and the positioning mechanism is used for limiting the square block to move.
