Abstract
The utility model relates to a bolt, which comprises a hex head and a threaded shank integrated with the hex head. A cross operation portion is arranged on the top of the hex head, a screw hole is arranged in the hex head, and the screw hole and the threaded shank are coaxial. The bolt has the advantages of capability of being used with hexagonal socket, and a slotted or a cross tool, and convenience in detachment.
Description
Technical field
The utility model relates to bolt.
Background technique
Bolt head is configured to hexagon, quadrilateral or Octagon usually, above-mentioned bolt is when dismounting, because instrument restriction, and can't realize dismounting, the assembling tool occupation space of Hexagonal jacket, four jiaos of sleeves or anistree sleeve is bigger, the bolt that is equipped with on some equipment is because spatial constraints, and can't be inserted in this polygonal head with this assembling tool, and is extremely inconvenient.
Summary of the invention
In order to overcome the problem of above existence, the purpose of this utility model be the to provide convenience bolt of dismounting.
The technical solution adopted in the utility model is:
Bolt comprises that hexagon-head and hexagon-head are holistic screw rod, and the top of described hexagon-head is provided with cross operation unit, is provided with screw in the described hexagon-head, described screw and screw coaxial.
The degree of depth of described screw is less than the length of hexagon-head.
Described cross operation unit is 4 symmetrically arranged grooves, and the degree of depth of described each groove is 3mm-8mm.
The utility model has the advantages that: be not subjected to instrument and spatial constraints, conveniently detachable.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Wherein: 1, hexagon-head, 2, screw rod, 3, cross operation unit, 4, screw, 5 grooves.
Embodiment
As shown in Figure 1, bolt of the present utility model comprises that hexagon-head and hexagon-head are holistic screw rod, the top of hexagon-head 1 is provided with cross operation unit 3, be provided with screw 4 in the hexagon-head, screw 4 is coaxial with screw rod 2, and the degree of depth of screw 4 is less than the length of hexagon-head 1, cross operation unit 3 is 4 symmetrically arranged grooves 5, the degree of depth of each groove 5 is 3mm-8mm, available Hexagonal jacket instrument, an also available word or cross instrument, be not subjected to spatial constraints, conveniently detachable.
