Abstract

The utility model relates to a regular polygon prism screw nail with a cross slot, which comprises a head of a screw nail and a screw rod, wherein, the end surface of the head of the screw nail is provided with a cross slot and a straight slot concentrical with the cross slot, and the head of the screw nail is in the shape of a regular polygon prism. The utility model is provided with three kinds of rotary positioning shape bodies, structure is simple and reliable, screw nails no matter new or old all can be screwed tightly or loosely successfully, and the utility model is the most practical screw nail in machine assembly.

Description

The just polygon prismatic screw of band crossed grooves
The utility model relates to a kind of engineering machinery part, especially a kind of fastening piece.
For a long time, the mechanical screw that uses on the engineering all is the globular model screw head, and the screw head end face has the point of intersection to cross the cross recess in screw axle center, to make the usefulness of turn screw.But this cross recess degree of depth is more shallow, and when making morpheme when not good enough, particularly after the corrosion, plus driver and cross recess interlock are shallow, and is very difficult even can't the turn screw, promptly can't unclamp the screw that gets rusty or screw screw.If the screw head end face also has a dark straight groove, and screw head is polygon prismatic, so just can adopt three kinds of diverse ways turn screws, and its effective probability is just inevitable much bigger.
The utility model purpose is to provide a kind of screw that several rotation positioning are arranged.
The utility model comprises screw head and screw rod, and the screw head end face has cross recess, also has a straight groove homocentric with cross recess, and it is just polygon prismatic that screw head is.
With embodiment and accompanying drawing the utility model is described in further detail below:
Fig. 1 is the utility model embodiment 1 a stereogram,
Fig. 2 is the utility model embodiment 2 a stereogram.
With reference to Fig. 1, the utility model comprises screw head 2 and screw rod 1, the straight groove 4 that screw head 2 end faces have cross recess 3 and overlap with cross recess 3 symmetrical line, and straight groove 4 connects screw head 2, and it is prismatic that screw head 2 is hexagon.
With reference to Fig. 2, the utility model comprises screw head 2 and screw rod 1, screw head 2 end faces have 2 orthogonal narrow and shallow grooves 5 and darker straight groove 4, narrow and shallow groove 5 and straight groove 4 constitute cross recess 3, straight groove 4 connects screw head 2, wherein a narrow and shallow groove 5 overlaps with straight groove 4, and screw head 2 is positive hexagon prism.When rotation positioning, the also available cross bottle opener of available in-line bottle opener in addition, can also block the both sides of positive hexagon prism with spanner.
The utility model is because there are three kinds of rotation positioning bodies, and simple and reliable for structure, no matter new and old screw all can screw smoothly unscrews, and is the most practical fastening piece in the machinery assembling.
