Description
Technical field
The utility model relates to a kind of special-shaped clamping screw spanner.
Background technology
Existing anti-theft bolt, by structural design and matching used spanner, achieves the fastening and anti-loosening effect of bolt.But, if utilize similar spanner, can be relatively easy bolt be opened, thus lose the effect of anti-unlatching.
Summary of the invention
The purpose of this utility model is to provide a kind of special-shaped clamping screw spanner, by the improvement to spanner, spanner is tightened to bolt, nut, closed after, spanner can not open bolt, nut again, and this spanner structure plays to be tightened and the object of anti-unlatching.
For achieving the above object, the utility model provides following technical scheme: a kind of special-shaped clamping screw spanner, and there is cylindrical cavity spanner one end, and hole exit end has perforate, and the other end is closed face, and its inwall has internal thread.Sleeve and handle form, and sleeve is a hollow cylinder, has dividing plate in sleeve, and dividing plate one end is hollow circular cylinder, and inwall has internal thread, and the other end has polygon shrinkage pool; There is polygon cylinder handle one end, and cylinder is square, hexagon etc., and cylinder is placed in shrinkage pool, and shape, structure, size reach unanimity.
Further, it is characterized in that: spanner is cuboid, the every one side on termination all has a cylindrical cavity, and each hole is not communicated with mutually, size, sets highly as required.
Further, it is characterized in that: spanner is cuboid, the every one side on termination all has an outstanding cylinder, and cylinder has external screw thread, size, sets highly as required.
Further, it is characterized in that: spanner is cuboid, the every one side on termination all has a polygon cylinder, size, sets highly as required.
Further, it is characterized in that: when spanner is rectangle cylinder, the termination on both sides is foursquare.
Further, spanner is polygon cylinder, each is at least arranged a hole; Spanner is cylinder as required, arranges a hole or cylinder at two ends every one end distance.
Further, the position that cylinder shrinkage pool in sleeve of handle one end is combined, its handle is the structure of ratchet spanner.
Further, have hole in one end of spanner, one of hole outlet by totally enclosed cover, another outlet is not closed, pass in and out for spanner, knob time.
Further, spanner is metallic article.
Further, stop being rotated down after spanner and quoit and washer contacts, and drive the rotary motion together of bolt, nut, until lock between bolts and nuts.
Further, when the height of nut external screw thread cylinder is greater than spanner internal height, spanner is without the need to just realizing tightening action by sheet metal, pad.
It further, after spanner inside top surface is combined with bolt, nut, cannot continue to move downward, so can drive bolt, nut rotation until tighten.
Further, spanner, by corresponding consistent with bolt, nut structure, can achieve fastening process.
Further, spanner tights a bolt and after nut, reversely rotates and realize and bolt, being separated of nut, do not drive bolt, nut to move in this process.
Further, in order to raise the efficiency, the internal thread number of turns of spanner arranges relatively less, and when satisfied can rotation on bolt, nut, the setting of few number of turns, realizes departing from screw bolt and nut fast.
Further, the process that spanner is tightened for turning clockwise, for being rotated counterclockwise when disengaging.
Further, after the internal thread in sleeve is combined with bolt, nut, realize rotate, fastening.
Further, compared with existing sleeved ratchet spanner, the structure of sleeve inner is not both the key of both differentiations.
Good result of the present utility model is: spanner can carry out fastening to special shaped screw bolt and nut, and realize to screw bolt and nut fastening after, spanner cannot the function of loose bolts and nut.So this spanner is the spanner of an one-way movement, by being rotated down clockwise, realize the fastening of bolts and nuts.Fastening complete after, by reciprocal knob, spanner is separated with bolt, nut.In this process, spanner does not apply power, so bolt, nut can keep fastening to bolt, nut.This spanner, after screwing bolts, nut, but cannot unclamp bolts and nuts, achieves the functions such as antitheft, anti-unlatching.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
As shown in figures 1-8, a kind of special-shaped clamping screw spanner, comprise a kind of special-shaped clamping screw spanner 1, there is cylindrical cavity 11 spanner 1 one end, and hole exit end has perforate, and the other end is closed face 12, its inwall has internal thread 111.
Concrete, the hole of spanner 1 one end is by being inserted on the cylinder of bolt or nut, and realization engaged through the thread screws up.When spanner 1 uses the structure of sleeve 2, sleeve 2 inside is the cylindrical structure of hollow, and inwall has internal thread 111.This facilitates sleeve 2 and the combination of bolt head, realizes knob and fix.Sleeve 2 is because of the difference of bolt, nut size, and its sleeve 2 internal diameter is also different.But, size, shape and spanner in the polygon shrinkage pool of sleeve 2 other end 1 the size and shape of column body reach unanimity.Cylinder cover on spanner 1, by ratchet device, realizes twisting action wherein.This sleeve 2 and traditional sleeve 2 maximum but not, the difference of sleeve 2 internal structure.Traditional sleeve 2 is hollow polygon cylinder, becomes now hollow circular cylinder 22, and on inwall with internal thread 111.Two kinds of sleeves 2 all need to use spanner 1 and realize reversing, and screw up.
Hole in rectangle structure in spanner 1 or cylinder, be in order in a spanner 1, can adapt to the size of multiple bolt head or nut.Illustrate, the two ends of rectangle cylinder, four faces have hole or the cylinder of 8 different pore sizes, like this, one can adapt to bolt, the nut of multiple different size fork spanner 1.If arrange multiple hole or cylinder in the one side of spanner 1, the size of more bolts, nut just can be adapted to.In use, fork spanner 1 and sleeve 2 spanner 1 combinationally use, and also can combinationally use with fork spanner 1 by fork spanner 1.
