For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of screw fastener is provided, comprise: loam cake, base and brace, described loam cake is connected with base by brace, described loam cake is provided with a buckle, the cross counter sink, the first optical cable crossed beam trunking and first pressuring line groove, be respectively arranged with an interface on the described base, via hole, the second optical cable crossed beam trunking and second pressuring line groove, after described loam cake superposes by brace and base, buckle snaps onto in the interface, described cross counter sink is aimed at via hole, the opening part of the first optical cable crossed beam trunking is aimed at the opening part of the first optical cable crossed beam trunking, and the opening part of first pressuring line groove is aimed at the opening part of second pressuring line groove.

In preferred embodiment of the utility model, all be provided with independently cavity for butterfly optical cable and messenger wire, avoid optical cable and messenger wire to be intertwined, the notch of the described first optical cable crossed beam trunking is formed first " 8 " the font cavity body structure with the corresponding stack of notch of the second optical cable crossed beam trunking; The notch of described first pressuring line groove is formed second " 8 " the font cavity body structure with the corresponding stack of notch of second pressuring line groove.

In preferred embodiment of the utility model, consider the separate cabling of butterfly optical cable and messenger wire, and don't change original Wiring technique, be provided with single track line ball bar in the groove of the described first optical cable crossed beam trunking and the second optical cable crossed beam trunking, be provided with two pass line ball bar in the groove of described first pressuring line groove and second pressuring line groove.

In preferred embodiment of the utility model, carry with easy for installation for making product, to optimize product structure, described loam cake, base and brace are the integrated through injection molding structure, save cost of goods manifactured.

In preferred embodiment of the utility model, for not being subjected to the interference of extraneous item environments after making loam cake and base correspondence folding, the width of described loam cake is equal to the width of base, and the length of described loam cake is equal to the length of base.

The beneficial effects of the utility model are: the utility model adopts the box-type clip of being made up of loam cake and base, and box-type clip inside is provided with a plurality of cavitys, can satisfy the combined type wiring of butterfly optical cable and messenger wire, and is easy for installation, saves cost.
