Abstract
The utility model discloses a screw which comprises a screw rod body and a head and is characterized in that the end head of the screw rod body is provided with a groove. As an improvement of a common screw or bolt, the screw can solve the problem of screw rotation caused when the screw and a screw cap are mutually fastened or loosened, thereby enabling the assembly and disassembly processes to be simple and labor-saving.
Description
[technical field]
The utility model relates to a kind of General fasteners, and what be specifically related to is the improvement invention of a kind of screw or bolt.
[background technique]
Screw or bolt are as a kind of prevailing fastening piece, its shadow can both be seen in each corner in the life, the problem that many people that often come into contacts with it run into headache is exactly screw rotation (screw rotates with the rotation of nut) and the bad again tool holding of using of screw head, because after screw and nut generation rotation, if can not clamp the head of screw well with instrument, wanting to tighten or loosen nut is exactly a very difficult thing, and the installation and removal process will become very to waste time and energy; And all as easy as rolling off a log in many cases generation of screw rotation, existing as the screw thread of screw and nut has the residual or screw thread of foul to get rusty or the like between damage or jagged, the screw thread.
[summary of the invention]
In view of the problem that present known technology exists, the technical problems to be solved in the utility model is to be to provide a kind of screw that can solve the rotation problem, makes installation, unloading process become simply laborsaving.
For solving the problems of the technologies described above, the utility model takes following technological scheme to finish:
A kind of screw includes screw rod body and head two-part, and it is characterized in that: the termination of screw rod body is provided with groove.The shape of described groove can be hexagon or in-line or cross.
Adopt the screw of technique scheme, if in installation, unloading process, run into screw with nut rotation, the bad situation of screw head with tool holding, can use the instrument suitable with screw grooves, can can then use cross head driver with flat head screw-driver, cross groove with inner hexagon spanner, in-line groove as hex-shaped recess, screw is lived, so, screw rotation problem just can obtain very simple and effective processing, installation, unloading process also just become simply laborsaving, save unnecessary trouble.
