Have one with the first screw mandrel of spiral thread,
And second screw mandrel with spiral thread,
Described the first screw mandrel, the second screw mandrel and screw head three form the one fixed structure, and the first screw mandrel and the second screw mandrel are separately fixed at the both sides of screw head.The present invention is by improving, and the self tapping screw assembly that proposition has double end can be used between two kinds of objects gapped fixing, with the use contrast of air pressure nail, door pocket is more firm, is used for fixing between door pocket and body of wall, do not reveal screw terminal, do not affect the overall appearance degree.
According to a kind of double end self tapping screw member of the present invention, it is characterized in that: on the first screw mandrel with screw thread and the second screw mandrel on hand of thread spiral identical or opposite.When Hand of spiral was identical, rotating its screw mandrel did not affect gap between two articles; When Hand of spiral is opposite, rotate its screw mandrel gap between adjustable two articles.
According to a kind of double end self tapping screw member of the present invention, it is characterized in that: the first screw mandrel and the second screw mandrel are weldingly fixed on screw head.
According to a kind of double end self tapping screw member of the present invention, it is characterized in that:
Comprise a fastening swivel assembly, fastening to the rotation of self tapping screw assembly integral body for being stuck on screw head, swivel assembly has the purpose of fast rotational screw in use, such as atwirl spanner of picture,
Have a swivel assembly body, the swivel assembly body is used for piercing into the screw mandrel of self tapping screw with a socket, and the middle part has the screw head fixed hole corresponding with the screw head shape.
According to a kind of double end self tapping screw member of the present invention, it is characterized in that:
The swivel assembly body is circular.
Beneficial effect of the present invention is: the present invention provides a kind of self tapping screw assembly with double end by improvement, can be used between two kinds of objects gapped fixing, such as fixing between door pocket and body of wall, simple in structure, easy to use fixedly the time intensity large, moreover, can be used for equally other field.

Embodiment
The present invention will be described below in conjunction with accompanying drawing, and the technological scheme in the embodiment of the present invention is clearly and completely described, and obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment who obtains under the creative work prerequisite.
The present invention is achieved through the following technical solutions:
The present invention provides a kind of double end self tapping screw assembly at this, has a screw head 101, be used for driving the rotation of self tapping screw integral body, has one with the first screw mandrel 102 of spiral thread 102a, and second screw mandrel 103 with spiral thread 103a, described the first screw mandrel 102, the second screw mandrel 103 and screw head 101 threes form the one fixed structure, and the first screw mandrel 102 and the second screw mandrel 103 are separately fixed at the both sides of screw head 101.
when double end self tapping screw assembly of the present invention uses, can complete by a fastening swivel assembly 104, be used for being stuck on screw head 101 fastening to the rotation of self tapping screw assembly integral body, fastening swivel assembly 104 has a swivel assembly body 104a, swivel assembly body 104 is with a socket 104b, convenient screw mandrel by self tapping screw, the middle part has the screw head fixed hole 104c corresponding with screw head 101 shapes, swivel assembly body 104a can be circle, fastening swivel assembly 104 injects by socket 104b, and by fixed hole 104c, fastening swivel assembly 104 is stuck on the self tapping screw assembly, and under external force, drive self tapping screw assembly integral-rotation, reach two screw mandrel fastening.
double end self tapping screw assembly of the present invention can be used for fixing between two kinds of objects, and fixing etc. such as between door pocket and body of wall can be used for other field equally, concrete condition during according to use, on the first screw mandrel 102 with screw thread 102a and the second screw mandrel 103 on Hand of spiral corresponding to screw thread 103a identical or opposite, such as when be used between door pocket and body of wall fixedly the time, on the first screw mandrel 102 with screw thread 102a and the second screw mandrel 103 on Hand of spiral corresponding to screw thread 103a opposite, during use, respectively with the first screw mandrel 102, the second screw mandrel 103 correspondences are placed in body of wall 105, door pocket 106, fastening swivel assembly 104 injects by socket 104b and is placed on the first screw mandrel 102 or the second screw mandrel 103, and by fixed hole 104c, fastening swivel assembly 104 is stuck on screw head 101, this moment under external force, by being circular swivel assembly body 104a drive self tapping screw assembly integral-rotation, by two screw mandrel, door pocket 106 is fastened on body of wall 105.Double end self tapping screw assembly of the present invention can be used for other field equally.
