Abstract
The utility model discloses a screw of which the service life is prolonged. The screw comprises a threaded rod and a nut, and is characterized in that the top part of the nut is provided with a cross-shaped groove, and the cross-section shape of the nut is a regular polygon. As the cross-section shape of the nut can be the regular polygon, when in use, the screw can be tapped by using a screw driver to be screwed into timber. After the screw disclosed by the utility model is used for multiple times, under the condition that the groove is damaged, the screw can be screwed into the timber by using a spanner.
Description
Technical field
The utility model relates to a kind of fastening piece, relates in particular to a kind of convenience and facilitates the propelling can nonexpondable screw in reinforcing process.
Background technique
The screw that can use in daily life can only advance by single use screw-driver, and some screw can be installed and removed repeatedly and carry out, and tends to occur nut groove destroyed situation in the process that advances, and groove is destroyed, and screw just is dropped.
Summary of the invention
The purpose of this utility model is to provide a kind of in the situation that the breakage of nut groove, and the screw that can continue to use so just can extend working life of screw, reduces the waste of resource.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of screw comprising screw rod, nut, is characterized in that: the top of nut is with " cross " type groove, and the sectional shape of nut is regular polygon.
The sectional shape of nut is regular hexagon.
The utility model has the advantages that: can use screw-driver tapping precession timber in use.If after repeatedly using, in the situation that groove wrecks, can use spanner precession timber.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In accompanying drawing: 1, screw rod; 2, nut; 3, groove.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
It is polygonal nut 2 that the utility model adopts the cross section, and the screw that can effectively solve in the past can only be with the problem of screw-driver tapping.
In practice, some screw can be installed and removed repeatedly and carry out, and the time tends to the situation that groove destroys occur for a long time in the process that advances, and groove 3 is destroyed, and screw just is dropped and screw can't be extracted.The utility model is abandoned the nut of circle in the past, can effectively extend the life-span of screw, and spanner equally can precession.
The sectional shape of the utility model embodiment's nut adopts regular hexagon.
Embodiment recited above is described preferred implementation of the present utility model; be not that design of the present utility model and protection domain are limited; under the prerequisite that does not break away from the utility model design concept; various modification and improvement that in related domain, common engineers and technicians make the technical solution of the utility model all should fall into protection domain of the present utility model.
Claims (2)
1. screw, comprising screw rod (1), nut (2), it is characterized in that: the top of nut (2) is with " cross " type groove (3), and the sectional shape of nut (2) is regular polygon.
2. screw according to claim 1, the sectional shape that it is characterized in that nut (2) is regular hexagon.
