As a further improvement of the above technical scheme, the screw drilling sword is "-" type sword.
The utility model has the beneficial effects that：The utility model, which provides, a kind of can be applied to the novel of field of aerospace
Screw, the screw that this kind can be applied to field of aerospace can carry out pretwist in application by the first screw terminal, into one
Step can utilize plum blossom tooth and flight to fix screw tightening, with easy to operate, fixed form is various；In addition, by described
First screw rod and the second screw rod can realize that the more firm connection that is screwed, the screw drilling sword shoot object convenient for screw
In, convenient for improving the installation effectiveness of screw.
In short, this kind can be applied to field of aerospace screw solve shape existing for existing screw it is single,
The inconvenient to use, technological deficiencies such as fastening effect is bad, installation effectiveness is low.
