Abstract
The utility model discloses two-tube screw, including nut and drilling pipe, the nut is detachable, the nut is connected with drilling pipe by screw thread a, the nut lower surface is provided with auxiliary fastener, and the sophisticated position of the auxiliary fastener is provided with overhead kick, and the auxiliary fastener is parallel with drilling pipe；The drilling pipe includes the first screwed pipe and the second screwed pipe, and first screwed pipe is connected by screw thread b with the second screwed pipe, and the screw thread b is identical with rotation direction with screw thread a sizes.The utility model screw length is variable, easy to use, and can reduce unnecessary waste.
Description
Technical field
The utility model is related to screw field, particularly two-tube screw.
Background technology
The screw of prior art includes a nut and the screw rod in screw head, and nut is integrated with screw rod, on screw rod
Provided with screw thread, the function of locking positioning is reached by screw thread, current screw length is fixed.But in actual applications,
Screw is long, causes head of screw exposed, not only influences attractive in appearance, and exposed head of screw is also easy to scratch the body part of people；If
Screw is too short, then does not reach the requirement of locking, and part is easily rocked.To avoid above-mentioned technical problem, it is necessory to provide one kind
More advanced screw, to overcome the defect of the prior art.
Utility model content
（One）The technical problem to be solved
Screw is long, causes head of screw exposed, not only influences attractive in appearance, and exposed head of screw is also easy to scratch the body of people
Position；If screw is too short, the requirement of locking is not reached, part is easily rocked.
（Two）Technical scheme
The purpose of this utility model is to provide two-tube screw, the problem of to solve above-mentioned set forth above.
To achieve the above object, the utility model provides following technical scheme：Including nut and drilling pipe, the nut is removable
Unload, the nut is connected with drilling pipe by screw thread a, the nut lower surface is provided with auxiliary fastener, the auxiliary fastener
Sophisticated position is provided with overhead kick, and the auxiliary fastener is parallel with drilling pipe；
The drilling pipe includes the first screwed pipe and the second screwed pipe, and first screwed pipe is connected by screw thread b with the second screwed pipe, institute
State screw thread b identical with rotation direction with screw thread a sizes；
When the workpiece to be locked is relatively thin, nut and the first screwed pipe can be screwed off, nut is connected with the second screwed pipe by screw thread b
Connect, remaining first screwed pipe can be reused, save raw material, then hammered into instrument in workpiece, now the auxiliary lock on nut
Tight part is also tufted into workpiece, and inside workpiece is caught in the overhead kick on auxiliary fastener, screw is more consolidated, is difficult to rock；
When the workpiece for finding to be locked needs longer screw, then one or more first screwed pipes can be added, to protect
Card reaches that locking is required.
It is preferred that, the surface of the nut is provided with the frictional force of decorative pattern, increase hand and nut, screws on nut and tightens more
It is convenient.
（Three）Beneficial effect
Compared with prior art, the beneficial effects of the utility model are：
1st, the utility model can screw off nut and the first screwed pipe according to the length of actual conditions adjusting screw, will
Nut is connected with the second screwed pipe by screw thread b, it is ensured that screw prevents from scratching the body part of people without exposed long, remaining
First screwed pipe can be reused, and saved raw material, hammered into instrument in workpiece, now the auxiliary fastener on nut is also tufted into
In workpiece, inside workpiece is caught in the overhead kick on auxiliary fastener, screw is more consolidated, is difficult to rock, not only saves material, also
It can guarantee that locking quality.
2nd, the surface of the nut be provided with decorative pattern, increase hand and nut frictional force, make nut screw on tighten more facilitate.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：1st, nut, 2, drilling pipe, the 3, first screwed pipe, the 4, second screwed pipe, 5, auxiliary fastener, 6, screw thread a, 7, screw thread
b。
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Embodiment, referring to Fig. 1, the utility model provides a kind of technical scheme：Including nut 1 and drilling pipe 2, nut 1 can
Dismounting, nut 1 is connected with drilling pipe 2 by screw thread a6, and the lower surface of nut 1 is provided with auxiliary fastener 5, the tip of auxiliary fastener 5
Position is provided with overhead kick, and auxiliary fastener 5 is parallel with drilling pipe 2；Drilling pipe 2 includes the first screwed pipe 3 and the second screwed pipe, and the first screwed pipe 3 leads to
Cross screw thread b7 to be connected with the second screwed pipe, screw thread b7 is identical with rotation direction with screw thread a6 sizes；When the workpiece to be locked is relatively thin, Ke Yixuan
The lower screwed pipe 3 of nut 1 and first, nut 1 is connected with the second screwed pipe 4 by screw thread b7, and remaining first screwed pipe 3 can be sharp again
With, raw material is saved, then hammered into instrument in workpiece, now the auxiliary fastener 5 on nut 1 is also tufted into workpiece, auxiliary lock
Inside workpiece is caught in overhead kick on tight part 5, screw is more consolidated, is difficult to rock；When the workpiece needs for finding to be locked are longer
Screw when, then can add one or more first screwed pipes 3, with ensure reach locking require.
Operation principle：When the workpiece to be locked is relatively thin, the screwed pipe 3 of nut 1 and first can be screwed off, it is ensured that screw is without exposed
It is long, prevent from scratching the body part of people, nut 1 is connected with the second screwed pipe 4 by screw thread b, remaining first screwed pipe 3 can be with
Reuse, save raw material, then hammered into instrument in workpiece, now the auxiliary fastener 5 on nut 1 is also tufted into workpiece,
Inside workpiece is caught in overhead kick on auxiliary fastener 5, screw is more consolidated, is difficult to rock；
When finding that the workpiece to be locked needs long spiro nail, then one or more first screwed pipes 3 can be added, to ensure to reach
Required to locking.
It is described above, only the utility model preferably embodiment, but protection domain of the present utility model is not
This is confined to, any one skilled in the art is in the technical scope that the utility model is disclosed, according to this practicality
New technical scheme and its improvement design is subject to equivalent substitution or change, should all cover in protection domain of the present utility model
It is interior.
