Abstract
The utility model discloses a special hollow socket spanner used for installing and disassembling an inner heptagonal anti-theft nut, which is a special too used to install and disassemble a non-standard nut with special structure and shape. The special hollow socket spanner comprises a socket body(1), a socket spanner handgrip(2), an outer circumferential wall(3) of the socket body, outer circumferential walls(4)at the joints of the ridges of the outer circumferential wall(3) of the socket body, a socket bottom(5). A trepanned bore(6)communicated with the interior of the socket body is arranged on the socket body(1). The socket spanner is a special tool used for installing and disassembling a non-standard nut with an outer circumferentially tapered exterior wall and a U-shaped top opening. When being matched with an inner heptagonal nut, the socket spanner can be used for fixing and installing or fixing and replacing outdoor electric power, traffic, telecommunication and environment protection equipment that is easy to be stolen for the purpose of guarding against theft. Therefore, the socket spanner has obvious social benefits.
Description
Technical field
The utility model is a kind of specific purpose tool that the non-standard fastener screw of special construction and shape is adorned, torn open, and more particularly, it is the cannulated sleeve spanner of a kind of non-standard fastener screw special use.
Background technology
1, existing general inner hexagon spanner, be a kind of solid hopkinson bar, outer bar wall is hexagonal spanner, it is the general utility tool that the screw of hexagonal is adorned, torn open in can only being the screw top hole, because of clear in this screw top hole, so both can insert with solid hopkinson bar outer-hexagonal spanner, also rotatable dress, tear open.
Though general utility tool is bought and dress, tear open all and make things convenient for, non-anti-theft because everybody can buy, removable.
2, be the excircle tapered wall for outer wall, interior apical pore is the non-standard anti-theft nut of shape such as heptangle in " U " font, because of all nuts could be fixed after all should spinning being anchored on the corresponding screw threaded rod, after fastened threaded rod passes through " U " font nut thread hole, top spiro rod section is protruding for it when being higher than baseplane, the female apical pore hole of " U " font, the setting of female apical pore has then become and has fallen the structure of " towel " font, routine, the spanner of hexagonal isogonism number is then stopped by the protruding high spiro rod section in female apical pore and can't sleeve goes into and be rotated in female apical pore in the general solid hopkinson bar, installed and removed.
The solid spanner of outer-hexagonal, the nut of heptangle isogonism number in can not adorning, tearing open.
3,, can only use the cannulated sleeve spanner of this respective corners number to go in the female apical pore of " U " font to be rotated, to install and remove by sleeve for being interior heptangle " U " the font nut that purpose is provided with antitheft.
The utility model has solved obstacle in the hole of this artificial setting effectively, reached non-this specific purpose tool can not adorn, tear open in the antitheft effect of heptangle nut.
4, this cannulated sleeve spanner, also be widely used in outer wall be the excircle tapered wall, the screw top hole be down the non-standard anti-theft screw nail of " towel " font dress, tear use open.
5, to ending at present, whole securing member market had not both had the interior heptangle nut that is " U " font, did not have the interior heptangle screw that is down " towel " font screw top hole yet, had not had the utility model cannulated sleeve spanner naturally yet.
Summary of the invention
The purpose of this utility model is for overcoming deficiency of the prior art, provides in a kind of the utility model that heptangle nut in " U " font of special setting etc. is installed and removed the heptangle anti-theft nut to install and remove special-purpose cannulated sleeve spanner technology.
The technical scheme that its technical problem that solves the utility model adopts is:
The heptangle anti-theft nut is installed and removed special-purpose cannulated sleeve spanner in the utility model, comprise at the bottom of sleeve cylindrical shell 1, box spanner handle 2, sleeve cylindrical shell periphery wall 3, the alternate periphery wall 4 of sleeve cylinder body outer wall rib and the sleeve tube 5, on sleeve cylindrical shell 1, be provided with string trepanning 6 in the sleeve cylindrical shell with the rib plane.
The beneficial effects of the utility model are:
1, the utility model is that heptangle anti-theft nut in " U " font and screw top hole are down the specific purpose tool that the heptangle anti-theft screw is installed and removed in " towel " font, has reached the effect that non-this specific purpose tool can not be installed and removed heptangle nut in " U " font;
2, the utility model is simple in structure, adorns, tears open conveniently, and cheap, favourable antitheft, social benefit is obvious.
Description of drawings
Fig. 1 is the utility model general structure schematic diagram.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
At the bottom of the box spanner handle 2 that is respectively equipped with conjoined structure on the sleeve cylindrical shell 1 of Fig. 1, sleeve cylindrical shell periphery wall 3, the alternate periphery wall 4 of sleeve cylinder body outer wall rib and sleeve tube 5, on sleeve cylindrical shell 1, be provided with string trepanning 6 in the sleeve cylindrical shell of conjoined structure with the rib plane.
