Description

Nut bolt extractor

Technical field

The utility model relates to the technical field of hardware ＆ tools, particularly relates to a kind of nut bolt extractor.

Background technology

Nut, the bolt of painting layer are worn and torn, got rusty and covered, is difficult dismounting at present, mostly using the clamping such as vice Instrument clamping screw nut or bolt are dismantled, and a large amount of manpowers are often expended in unloading process and are difficult to disassemble, are had at present There is bolt extractor, but make screwed hole inside it, after being connected by screwed hole with bolt thread, rotate extractor by bolt Disassemble, screwed hole easily causes sliding dent trauma in the case of by larger torsion, cause to take out failure.

Utility model content

In order to overcome drawbacks described above, the utility model provides a kind of nut bolt extractor, the nut bolt extractor knot Structure is simple, can realize abrasion, gets rusty and cover the nut of painting layer, bolt, fast quick-detach.

The utility model is in order to solve the technical scheme that its technical problem is used：A kind of nut bolt extractor, takes out Device one end, which is formed with to be formed with along bus on the external taper hole that one end diameter is more than other end diameter, external taper hole madial wall, to be extended Tooth slot structure, the external taper hole cross section of described extractor one end is in multi-corner star-shape structure, the formation operation of the extractor other end Handle.

As further improvement of the utility model, the lever of the extractor other end is non-circular column structure.

As further improvement of the utility model, the lever of the extractor other end is hexagonal handle.

As further improvement of the utility model, the extractor is the Step-edge Junction that one end external diameter is more than one end external diameter Structure.

As further improvement of the utility model, the lever of the extractor other end is circular cylinder, circular columns Internal side forms four square holes or hexagon ring.

As further improvement of the utility model, the lever periphery wall of the extractor other end is provided with one Ring fillister is enclosed, ring fillister is provided with the radial perforation connected with four square holes or hexagon ring.

As further improvement of the utility model, the extractor is high hardness alloy steel integrated formed structure.

The beneficial effects of the utility model are：The utility model in extractor one end by setting multi-corner star-shape external taper Hole, is sleeved on nut or bolt surface, because of the taper undergauge compressing occlusion nut or screw in external taper hole, can realize mill Nut, the bolt of painting layer are damaged, get rusty and cover, fast quick-detach is dismantled easily, conveniently, multi-corner star-shape external taper hole and spiral shell Female, bolt occlusion great efforts, the extractor external taper hole internal spline that high hardness alloy steel is processed not cracky, can bear Huge torsion, and the utility model is simple in construction, compact, easy to use, manufacturing cost is low, easy to carry and store.

Embodiment

Embodiment：A kind of nut bolt extractor, it is outer more than other end diameter that extractor one end is formed with one end diameter The tooth slot structure extended along bus, the external taper hole 1 of described extractor one end are formed with tapered hole 1, the madial wall of external taper hole 1 Cross section is in multi-corner star-shape structure, and extractor other end formation lever, the utility model is applied to dismounting abrasion, gets rusty and cover Nut, the bolt of lid painting layer, when dismounting nut or bolt, nut or bolt are inserted the external taper hole 1 of extractor one end Interior, because of the taper undergauge compressing occlusion nut or screw in external taper hole 1, then rotation process handle is that can reach that nut will be damaged The function that bolt takes out rapidly, extractor one end is polygonal star-like external taper, plays bigger snap-in force, can make various nuts, Bolt quickly dismounts driving.

The lever of the extractor other end is non-circular column structure, convenient to be used cooperatively with other instruments, is increased Torsion, nut, bolt are quickly removed.

The lever of the extractor other end is hexagonal handle 2, is easily installed on electric drill and dismantles nut bolt.

The extractor is the ledge structure that one end external diameter is more than one end external diameter, and ledge structure is easy to nesting tool to position.

The lever of the extractor other end is that four square holes or hexagon ring 3 are formed on the inside of circular cylinder, circular cylinder, side Just it is arranged on electric drill and dismantles nut bolt.

The lever periphery wall of the extractor other end is enclosed on ring fillister 4, ring fillister 4 provided with one Provided with the radial perforation 5 connected with four square holes or hexagon ring 3, by the setting ring fillister 4 on lever and on groove Setting radial perforation 5, can facilitate by setting pin etc. to operate and with inserting in four prevention and control and hexagon ring in perforation Instrument is securely attached to together, it is to avoid the two departs from use, and radial perforation 5 can also be radial screw bore, is used In the turn of the screw.

The extractor is high hardness alloy steel integrated formed structure, and polygonal nut bolt extractor is by high hardness alloy steel Process, intensity is big, hardness is high, and the tooth slot structure in it is difficult to be destroyed, can firmly be engaged nuts and bolt surface.
