Abstract
The invention discloses a multi-head screw, composed of a screw rod and a screw head, wherein the screw rod is provided with a thread; the screw head is arranged on the screw rod; an inner hexagon counter bore is arranged in the screw head; the screw head is like a rectangular structure; a crossed groove is arranged on the bottom of the inner hexagon counter bore; and a straight groove is arranged on the bottom of the inner hexagon counter bore. The multi-head screw provided by the invention has the advantages that structure is simple; adaptation range is wide; the multi-head screw can be mounted according to carried tools when mounting; work efficiency is ensured; and production cost is low, therefore, the multi-head screw is popularized conveniently.
Description
Technical field
The present invention relates to a kind of screw, relate in particular to a kind of bull screw.
Background technique
Screw is as the extensively utilization in present production and life of a kind of connection fittings; Because its good connecting effect is convenient to dismounting, therefore obtain people's generally approval.Mostly the screw terminal of existing screw is single structure, like the hole countersunk structure, and crosshead or flat head; The screw of the screw terminal structure that this type is single has certain restriction to setting tool when installing; Install if the staff will influence product with single setting tool when some screws are installed, reduce working efficiency.
Summary of the invention
Technical problem to be solved by this invention is that a kind of bull screw of being convenient to multiple setting tool operation is provided.
In order to solve the problems of the technologies described above, the present invention realizes through following technological scheme: a kind of bull screw, and, threaded lead screw forms hexagonal counterbore in said screw terminal top is provided with by being set with the screw terminal that is arranged on the lead screw top.
Use spanner for ease, further, the rectangular structure of said screw terminal.
Use cross head driver for ease, more further, said interior hexagonal counterbore bottom is provided with cross recess.
Use the flat head screw-driver for ease, further, said interior hexagonal counterbore bottom is provided with straight groove.
Compared with prior art, usefulness of the present invention is: this bull screw structural is simple, and wide accommodation can be installed according to the instrument of carrying during installation, guarantee working efficiency, and cost of production is low, is convenient to promote.
Description of drawings:
Below in conjunction with accompanying drawing the present invention is further specified.
Fig. 1 is a kind of bull screw structural of the present invention schematic representation;
Fig. 2 is the plan view of Fig. 1.
Among the figure: 1, screw terminal; 2, lead screw; 3, interior hexagonal counterbore; 4, cross recess.
Embodiment:
Describe the present invention below in conjunction with accompanying drawing and embodiment:
Fig. 1, a kind of bull screw shown in Figure 2 are formed with the screw terminal 1 that is arranged on lead screw 2 tops by threaded lead screw 2 is set, and said screw terminal 1 top is provided with interior hexagonal counterbore 3; Use spanner for ease, said screw terminal 1 rectangular structure; Use cross head driver for ease, said interior hexagonal counterbore 3 bottoms are provided with cross recess 4; Use the flat head screw-driver for ease, said interior hexagonal counterbore 3 bottoms are provided with straight groove.
This bull screw structural is simple, and wide accommodation can be installed according to the instrument of carrying during installation, guarantee working efficiency, and cost of production is low, is convenient to promote.
It is emphasized that: above only is preferred embodiment of the present invention; Be not that the present invention is done any pro forma restriction; Every foundation technical spirit of the present invention all still belongs in the scope of technological scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
