Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model discloses an improve and provide a detachable stainless steel screw here, as shown in fig. 1-fig. 3, including threaded

rod

1, 1 upper end of threaded rod is fixed with

dop

2, and 2 outer walls of dop have seted up four

spacing grooves

3, 2 outer wall blocks of dop have hexagon screwhead 5, and surface mounting has four stopper 6 under the hexagon screwhead 5, four stopper 6 and four spacing grooves 3 are three horn shapes, spacing groove 3 is identical with stopper 6's internal and external opening size, stopper 6 of its lower surface of hexagon screwhead 5 accessible of setting carries out the block with the spacing groove 3 of 1 dop 2 outer wall of threaded rod, thereby it is convenient to make threaded rod 1 twist equipment downthehole through twisting hexagon screwhead 5, can outwards extract hexagon screwhead 5 after twisting, make threaded rod 1 be located equipment hole alone, its process can prevent that other people from using tools from twisting out the screw, thereby improve equipment's security, and four stopper 6 and spacing grooves 3 that are three horn shapes can improve the block stability between hexagon screwhead 5 and the threaded rod 1, avoid taking place the fracture damage with 1 block of threaded rod 5 in rotatory in-process that twists, the screwhead, the structure of hexagonal screw has guaranteed the structure of screw.

The chuck 2 and the threaded rod 1 are integrally formed by injection molding, so that the structural strength of the head 5 of the hexagonal screw can be further improved, and the breakage and damage of the head in the rotation stress process can be avoided.
