Abstract
The utility model discloses a kind of screw, aim to provide one can avoid twisting the rear obsolete screw of screw of groove damage, its drip irrigation device is: described screw mainly comprises screw rod and screw head, described screw head is provided with mounting groove relative to the other end of screw rod, removably be provided with in described mounting groove and twist body, described twist to be provided with in external week somely twist groove, twist body by adjustment and make respectively to twist the opening that groove all can be positioned at mounting groove.It is independent mutually with screw head that the utility model screw will twist groove, when one, to twist groove impaired, the position can twisting body by adjustment is changed one and is twisted groove, groove is twisted all impaired even if all, or whole body of twisting is impaired, can change and twist body, whole screw can not be caused to use, Loss reducing, reduces costs.
Description
Technical field
The utility model relates to a kind of fastening piece, and more particularly, it relates to one and can avoid twisting the rear obsolete screw of screw of groove damage.
Background technique
At present, the screw on market generally comprises screw rod and screw head, is directly provided with twists groove at screw head.The simple convenient operation of this bolt structure, only need twist groove with screw-driver cooperation can realize twisting screw, but in operation, due to screw-driver with twist slot fit and be not easy to put in place, probably cause twisting groove impaired, and be directly arranged in screw head owing to twisting groove, twist that groove is impaired may directly cause screw unavailable, even cannot twist due to already installed screw and have influence on the use of relevant device.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is that providing one can avoid twisting groove damages the rear obsolete screw of screw.
For achieving the above object, the utility model provides following technological scheme: a kind of screw, mainly comprise screw rod and screw head, described screw head is connected with one end of screw rod, the outer wall of screw rod is provided with screw thread, it is characterized in that: described screw head is provided with mounting groove relative to the other end of screw rod, is removably provided with and twists body in described mounting groove, described twist to be provided with in external week somely twist groove, twist body by adjustment and make respectively to twist the opening that groove all can be positioned at mounting groove.
By adopting technique scheme, twist body to be detachably embedded in mounting groove, twist groove to be located at and to twist on body, twist body and screw independent mutually, and somely twist groove twisting body is provided with, when one twist groove impaired after can twist body by adjustment and change one and twist groove for twisting, groove is twisted all impaired even if all, even twist body impaired, can also take out and twist body, again change one and twist body.
The utility model is set to further: described in twist body be positive eight prisms, its both ends of the surface all with the axis parallel of screw rod.
By adopting technique scheme, further define the shape of twisting body, positive eight prism shapes are comparatively uniform and stable.
The utility model is set to further: described in twist body each side be equipped with and twist groove, twist slot on the center line of side, place, and twist groove twists body bottom surface perpendicular to eight prisms.
By adopting technique scheme, positive eight prisms have eight identical sides, ensure that enough grooves of twisting are for for subsequent use, twist the setting of putting slot enable screw-driver better with twist slot fit and put in place, more stable when twisting.
The utility model is set to further: comprise a groove bottom and the groove inclined-plane adjacent with groove bottom both sides bottom described mounting groove, three faces respectively with twist three sides that body is positioned at bottom mounting groove and fit.
By adopting technique scheme, it is more stable with coordinating of mounting groove to twist body, ensures that any one twists slot when the opening of mounting groove, and the bottom of mounting groove can be closed with twisting to show consideration for, and ensures the stability in the process of twisting and soundness.

Embodiment
Referring to figs. 1 through Fig. 4, the utility model screw embodiment is described further.
As shown in Figures 1 to 4, a kind of screw, mainly comprises screw rod 1 and screw head 2, and screw rod 1 outer wall is provided with screw thread 3.
Screw on market is generally directly provided with at screw head 2 and twists groove 6, and this structure twists groove 6 once the impaired screw that probably causes is unavailable, even has influence on the use of relevant device.In order to address this problem, we are separated twisting groove 6 with screw head 2: another side relative with screw rod 1 on screw head 2 establishes mounting groove 4, be embedded at mounting groove 4 and twist body 5, and this twists the detachable and adjustment position of body 5, be provided with in the periphery of twisting body 5 and somely twist groove 6.
By above-mentioned setting, we will twist groove 6 and be separated with screw head 2, when one, to twist groove 6 impaired, the position can twisting body 5 by adjustment is changed one and is twisted groove 6, and twist groove 6 even if all impaired, or whole body 5 of twisting is impaired, can change and twist body 5, whole screw can not be caused to use, Loss reducing, reduce cost of production.
Particularly, this twists body 5 can be positive eight prisms, also can be other shapes such as cuboid, six prisms, but in order to allow its side more as far as possible, again not because side too much causes offering the unnecessary trouble of twisting groove 6 in side, we select the shape of positive eight prisms.Preferably, the bottom surface of these positive eight prisms parallels with the shaft axis of screw rod 1, and the degree of depth of mounting groove 4 equals the thickness of twisting body 5, twists body 5 and can just embed in mounting groove 4, this is arranged so that mounting groove 4 and twists body 5 and coordinate more stable, and it is stressed more even to twist groove 6.
Positive eight prisms have eight identical sides, each side is respectively equipped with one and twists groove 6, preferably, this twists on center line that groove 6 is positioned at the side at its place and two bottom surfaces of through eight prisms, twist groove 6 twists body bottom surface perpendicular to eight prisms, this arrange same be in order to make to twist groove 6 stressed evenly, avoid due to cause by force unbalance to twist groove 6 easily damaged.
More stable during in order to twist, match with positive eight prisms in the bottom of mounting groove 4, the bottom of mounting groove 4 is made up of three adjacent surfaces, and middle face is groove bottom 7, the face of both sides is that face, 8, three, groove inclined-plane fits three sides be positioned at eight prisms bottom mounting groove 4 respectively.
When using this screw, first will twist body 5 and embed in mounting groove 4, now twist the opening that groove 6 is positioned at mounting groove 4 for one.Utilize this to twist groove 6 with straight screwdriver and twist this screw, when this twist groove 6 impaired time, take out twist body 5, adjust its position and again embed mounting groove 4, the opening of mounting groove 4 changes one and twists groove 6.When all grooves 6 of twisting are all impaired, or whole twist body 5 impaired unavailable time, take out and twist body 5, and again embed that another matches twist body 5.
The above makes preferred implementation of the present utility model, and under not departing from the prerequisite of the utility model principle for the person of ordinary skill of the art, can also make some modification and improvement, these also should be considered as protection domain of the present utility model.
