The aim of the utility model can be achieved by the following technical scheme: the utility model provides an antiskid is easy to bore screw, includes nail pole, nut and pin head, its characterized in that, the pin head is provided with main screw thread section to the direction of nail pole, main screw thread section is pineapple line screw thread section, still be provided with on the pin head with main screw thread section's the same helping thread section of direction of rotation, helping the screw pitch of attacking the screw thread section is less than the screw pitch of main screw thread section, helping the tooth height of attacking the screw thread section to be less than the tooth height of main screw thread section, still have the enhancement tooth on the starting end of main screw thread section.
The nail rod is also provided with an anti-skid knurl, and the rotation direction of the anti-skid knurl is opposite to that of the main thread section.
The nail head is of a conical structure.
The junction of nail cap and nail pole still is provided with the reinforcement portion.
The screw cap is also provided with a screw driver groove.
By adopting the structure, the main thread section adopts the pineapple thread section, the friction area of the whole screw is increased, the wood board is tapped in a bevel cutting mode, the structure inside the wood board is not damaged, the fit degree between the screw and the inside of the wood board is better realized, the connection between the screw and the inside of the wood board is firmer, the wood board is not easy to crack, the integrity of the wood board is better kept, meanwhile, the auxiliary thread section is additionally arranged at the nail head, the reinforcing teeth are matched, the size of the reinforcing teeth is larger than that of the normal teeth on the starting end, the tapping speed is greatly improved when the screw is conveniently tapped, the tail cutting procedure is replaced, the process period of the screw is greatly shortened, and the use effect is good.
Compared with the prior art, the anti-skid easy-drilling screw has the advantages that:
according to the utility model, the pineapple thread section is adopted as the main thread section, so that the friction area of the whole screw is increased, the wood board is tapped in a bevel cutting mode, the internal structure of the wood board is not damaged, the fit degree between the screw and the inside of the wood board is better realized, the connection between the screw and the inside of the wood board is firmer, the wood board is not easy to crack, the integrity of the wood board is better kept, meanwhile, the auxiliary tapping thread section is additionally arranged at the nail head to cooperate with the reinforcing teeth, the size of the reinforcing teeth is larger than that of the normal teeth at the starting end, the tapping speed is greatly improved while the tapping is convenient, the tail cutting procedure is replaced, the process period of the screw is greatly shortened, and the use effect is good.
