Description
Technical field
The utility model relates to Hardware fitting field, specially a kind of novel changable screw.
Background technique
Screw is also screw, is a kind of common Hardware fitting, is widely applied in daily life and industrial production, small to arrive
Wrist-watch, mobile phone arrive greatly automobile, aircraft, use screw, although screw structural is simple, application value is unable to estimate.
Screw too short problem is frequently encountered during using screw, the too short screw of screw enters screw hole leads very little
It causes adhesive force insufficient, the compression intensity of needs is not achieved, will increase the load of screw, be easily broken off screw.It is usually at present
The screw of different size length is manufactured to adapt to different situations, is badly in need of a kind of screw that can be can be changed with length at present.
Utility model content
The purpose of this utility model is to provide a kind of novel changable screws, to solve the problems, such as to mention in background technique.
To achieve the above object, the utility model provides the following technical solutions: including screw ontology, upper end stud and lower end
Stud；The screw ontology, which is connected by pedestal with extension, to be constituted, and the extension side is equipped with extension screw thread, the screw
Ontology is equipped with the through-hole through the pedestal and extension, and the through-hole inner surface is equipped with through hole whorl；Upper end stud top
End is equipped with recess, and upper end stud side is equipped with upper end stud screw thread, and the upper end stud screw thread and the through hole whorl are matched
Set；The lower end stud is connected with upper end stud bottom surface, and lower end stud side is equipped with lower end stud screw thread, under described
Hold stud thread size size identical with the extension screw thread.
Preferably, the recess is that cross is recessed.
Preferably, the pedestal is positive hexagonal base.
In use, extension is screwed into screw hole by spanner fixed pedestal, when extension is too short, screwdriver pair is used
Quasi- recess, the upper end stud screw thread and the through hole whorl are mating, and turning screwdriver can be such that upper end stud revolves from through-hole
Out, upper end stud drives lower end stud, lower end stud can be made to promote along screw hole screw thread, when Phillips screwdriver can not turn, at this time
Lower end stud touches screw hole bottom.The utility model simple structure.Design rationally, has Practical significance and promotional value, energy
Effectively solve the problems, such as that screw is too short, it is contemplated that good economic benefit can be generated.

Every other embodiment obtained, fall within the protection scope of the utility model.
Embodiment
In conjunction with Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, a kind of novel changable screw, including screw ontology 1, upper end stud 2 and under
Hold stud 3；The screw ontology 1, which is connected by regular hexagon pedestal 11 with extension 12, to be constituted, and 12 side of extension is equipped with
Extension screw thread 121, the screw ontology 1 is equipped with the through-hole 13 through the regular hexagon pedestal 11 and extension 12, described
13 inner surface of through-hole is equipped with through hole whorl 131；2 top of upper end stud is equipped with cross recess 21,2 side of upper end stud
Face is equipped with upper end stud screw thread 22, and the upper end stud screw thread 22 and the through hole whorl 131 are mating；3 He of lower end stud
2 bottom surface of upper end stud is connected, and 3 side of lower end stud is equipped with lower end stud screw thread 31, the lower end stud screw thread 31
Size is and the extension screw thread 121 is identical.
Utility model works principle: in use, extension 12 is screwed into spiral shell by spanner clamping regular hexagon pedestal 11
Kong Zhong uses Phillips screwdriver alignment cross recess 21, the upper end stud screw thread 22 and described when extension 12 is too short
Through hole whorl 131 is mating, and turning Phillips screwdriver can be such that upper end stud 2 screws out from through-hole 13, and upper end stud 2 drives lower end
Stud 3 can be such that lower end stud 3 promotes along screw hole screw thread, and when Phillips screwdriver can not turn, lower end stud 3 touches spiral shell at this time
Hole bottom.The utility model simple structure.Design rationally, has Practical significance and promotional value, it is too short to can effectively solve screw
The problem of, it is contemplated that good economic benefit can be generated.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
