Description
Technical field
The utility model is related to fastener areas, more particularly to a kind of special spiral rod.
Background technology
Screw rod refers to that outer surface cuts with the cylinder of helicla flute or cuts with the circular cone of Conical Spiral Groove.Existing screw rod is generally real
Heart cylinder, simply plays fastening effect, and solid material compares waste, and fastening effect is nor very well, and function compares
It is single.
Utility model content
The utility model is mainly solving the technical problems that provide a kind of special spiral rod, and its is reasonable in design, simple in construction, solution
Having determined, screw rod dismounting of the prior art is inconvenient, and function is single, the problem of easily coming off.
In order to solve the above technical problems, the technical scheme that the utility model is used is to provide a kind of special spiral rod, its
Including：First main body and the second main body；First main body includes upper screw head, upper screw rod and upper cross recess；Second main body
Including lower screw head, lower screw rod and lower cross recess；The upper cross recess is located at upper screw head upper surface center；The lower cross recess
Positioned at lower screw head upper surface center；The upper screw rod is connected to the lower surface of screw head；The lower screw rod is connected to lower spiral shell
The lower surface of head；Jack is respectively equipped with the upper screw rod and lower screw rod side wall；The upper pitch is provided with straight with lower screw rod
The corresponding screw in footpath.
Preferably, the upper screw rod and upper screw head are integral；The lower screw rod and lower screw head are integral；
Preferably, the upper screw head and lower screw head are hexagonal；
Preferably, the jack no less than three is equipped with the upper screw rod and lower screw rod, and is uniformly distributed；
Preferably, the screw inner surface is provided with internal thread, and corresponding with the external screw thread of lower screw surface.
The beneficial effects of the utility model are：The utility model is simple in construction, reasonable in design, and installation and removal are convenient to be held
Easily, and the first main body and the second main body can merge and use, can also be used alone, up and down screw rod connection can by jack come
The problem of preventing from easily coming off, facilitates the use of staff.

Embodiment
Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that advantage of the present utility model
It can be easier to be readily appreciated by one skilled in the art with feature, so as to make protection domain of the present utility model apparent clear and definite
Define.
Accompanying drawing 1 and Fig. 2 are referred to, the utility model embodiment includes：First main body 1 and the second main body 2；First master
Body 1 includes upper screw head 3, upper screw rod 4 and upper cross recess 7；Second main body 2 includes lower screw head 5, lower screw rod 6 and lower cross recess
8；The upper cross recess 7 is located at the upper upper surface center of screw head 3；The lower cross recess 8 is located at the lower upper surface centre bit of screw head 5
Put；The upper screw rod 4 is connected to the lower surface of screw head 3；The lower screw rod 6 is connected to the lower surface of lower screw head 5；The upper spiral shell
Jack 9 is respectively equipped with bar 4 and the side wall of lower screw rod 6；The center of upper screw rod 4 is provided with screw 10 corresponding with the lower diameter of screw rod 6.
It is further that the upper screw rod 4 and upper screw head 3 are integral；The lower screw rod 6 and lower screw head 5 are integral；
It is further that the upper screw head 3 and lower screw head 5 are hexagonal；
It is further the jack 9 no less than three to be equipped with the upper screw rod 4 and lower screw rod 6, and be uniformly distributed；
It is further that the inner surface of screw 10 is provided with internal thread, and corresponding with the external screw thread on the lower surface of screw rod 6.
In use, the first main body 1 and the second main body 2, which can be used alone to merge, uses；Merging is used
When can to carry out installation and removal by screw head and cross recess more convenient；Merge using can also be according to controlling the need for oneself
The length of one screw rod 1 and the second screw rod 2；And merge more solid using nut connection than usual, it is difficult to loosen.
Embodiment of the present utility model is the foregoing is only, the scope of the claims of the present utility model is not thereby limited, it is every
The equivalent structure or equivalent flow conversion made using the utility model description, or directly or indirectly it is used in other phases
The technical field of pass, is similarly included in scope of patent protection of the present utility model.
