The top screw type screw-tap screwdriver comprises a top screw type screw-tap screwdriver body and a top screw type screwdriver small-diameter left-hand screw tap or a top screw type screwdriver small-diameter right-hand screw tap, wherein a top screw type screwdriver large-diameter screwdriver handle is embedded at the upper half section of the top screw type screwdriver small-diameter left-hand screw tap or the top screw type screwdriver small-diameter right-hand screw tap, and a top screw surface at the bottom end of the top screw type screwdriver large-diameter screwdriver handle is arranged at the bottom end of the top screw type screwdriver large-diameter screwdriver handle. When used in combination with anti-theft screws and the like of the sealing cover at the bottom section of the street lamp post, the top screw type screw-tap screwdriver canperform the anti-theft screwing and mounting operation on sealing covers at the bottom sections of plenty of urban street lamp posts, thereby providing strong anti-theft safeguard for urban illumination at night and having obvious social benefits.
Description
Technical field
The utility model is a kind of specific purpose tool that city street lamp roofbolt anti-theft screw is installed and removed, and more particularly, it is a kind of nonstandard mounting or dismounting tools of installing and removing the non-standard fastener screw.
Background technology
To ending at present, also lack on the section seal closure at the bottom of all street lamp roofbolts in the vast city the real spinning anti-theft screw of effectively can anti-theft wire, can pilferproof closure and and its assembly and Disassembly special tool, cause copper core and seal closure cover plate in a large amount of street lamp roofbolts prized, stolen, cause a large amount of night street lamp blind, its oneself brought many inconvenience to life of people.
Summary of the invention
The purpose of this utility model is for overcoming deficiency of the prior art, for street lamp roofbolt anti-theft screw provides a kind of simple in structure, cheap, and the rotating screw tap trip-out in the top technology of simple load and unload the utility model mounting or dismounting street lamp roofbolt anti-theft screw special use.
The technical scheme that its technical problem that solves the utility model adopts is:
The rotating screw tap in top of the utility model mounting or dismounting street lamp roofbolt anti-theft screw special use pulls out of hole, comprise the top rotating screw tap drill body 1 that pulled out of hole, push up rotating trip-out minor diameter levoform screw screw tap 2 and levoform tap screw thread 3 or push up rotating trip-out minor diameter dextrorotation formula screw screw tap 4 and dextrorotation formula tap screw thread 5 and tap attack the point 6, at described top rotating trip-out minor diameter levoform screw screw tap 2 or push up inlaying on the upper semisection of rotating trip-out minor diameter dextrorotation formula screw screw tap 4 and push up rotating trip-out major diameter and play drillstock 7, the bottom of playing drillstock 7 in the rotating trip-out major diameter in top and the rotating trip-out minor diameter levoform screw screw tap 2 in top or push up inlaying of rotating trip-out minor diameter dextrorotation formula screw screw tap 4 upper semisections and be provided with the rotating trip-out major diameter in top on the joint face and play top, drillstock bottom radial facing 17.
The diameter that the rotating trip-out major diameter in described top plays top, drillstock bottom radial facing 17 is greater than the rotating trip-out minor diameter levoform screw screw tap 2 in top or push up the diameter of rotating trip-out minor diameter dextrorotation formula screw screw tap 4.The precession direction of described levoform tap screw thread 3 is just in time opposite with the precession direction of dextrorotation formula tap screw thread 5.
The beneficial effects of the utility model are:
1, at the bottom of the utility model and the street lamp roofbolt after the supporting use such as section seal closure anti-theft screw, can carry out antitheft spinning to section seal closure at the bottom of the vast city street lamp roofbolt uses, for the luminescent lighting in city provides the antitheft guarantee of strong anti-theft wire, pick-proof lid, its social benefit is obvious;
2, the utility model is simple in structure, and is cheap, adorns, tears open conveniently, obvious social benefit.
