Abstract

The utility model provides an adjustable buckle spanner, includes endotheca and overcoat, endotheca lower part surface is equipped with the screw thread section, and endotheca bottom equipartition encircles has a plurality of flexible sheet metal, and a plurality of flexible sheet metal form the horn shaped structure of an outside expansion, the overcoat includes body, the convergent divergent channel of body upper portion for taking internal screw thread pipe, lower part to suit for the horn shaped structure who constitutes with a plurality of flexible sheet metal. The utility model provides a pair of adjustable buckle spanner is through setting up endotheca and overcoat to set up flexible sheet metal at the endotheca lower extreme, but set up the round bar that the short distance was slided in the endotheca, and then the realization is tight to countersink bolt's curb pins, the bolt carries out the loosening or screws the most at last.

Description

A kind of adjustable fastener spanner

Technical field

This utility model relates to a kind of hardware & tools, especially a kind of adjustable fastener spanner.

Background technology

There is two large problems in existing spanner: 1), model specification various, the use scope of common spanner is restricted；2) dormant bolt, being arranged on specific position (position relatively deep or relatively narrower) uses very inconvenient；3), for some special occasions (being easily subject to corrosion, dormant bolt is easily generated the situation of deformation), common wrench cannot use at all.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of adjustable fastener spanner, it is possible to suitable in the dormant bolt under different model or special state, and convenience unscrews being arranged on relatively deep or relatively narrower bolt or screws.

For solving above-mentioned technical problem, this utility model be the technical scheme is that

A kind of adjustable fastener spanner, including inner sleeve and overcoat, described inner sleeve lower external face is provided with thread segment, uniform bottom inner sleeve is surrounded with multiple elastic sheet metal, and multiple elastic sheet metals form a horn-like structure expanded outwardly；Described overcoat includes body, and body top is tapped pipe, bottom is the expansion pipe that the horn-like structure constituted with multiple elastic sheet metals adapts.

Described inner sleeve and outer set upper side are equipped with handle.

Described elastic metallic plate inner surface is provided with anti-skidding projection.

Being provided with one section of cavity in described inner sleeve bottom, many round bars are arranged in cavity and round bar magnetic is contrary with the magnetic of cavity bottom.

Described elastic sheet metal is provided with magnetisable material, and magnetisable material makes elastic sheet metal mutual exclusion.

A kind of adjustable fastener spanner of this utility model, by arranging inner sleeve and overcoat, and arranges elastic sheet metal in inner sleeve lower end, arrange in inner sleeve can the round bar of short distance sliding, and then realize the inside and outside clamping to dormant bolt, bolt carries out unscrewing or screwing the most at last.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is described in further detail:

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the structural representation of inner sleeve in this utility model.

Fig. 3 is top view of the present utility model

In figure: inner sleeve 1, overcoat 2, thread segment 3, elastic sheet metal 4, body 5, handle 6, anti-skidding protruding 7, round bar 8.

Detailed description of the invention

As Figure 1-3, a kind of adjustable fastener spanner, including inner sleeve 1 and overcoat 2, described inner sleeve 1 lower external face is provided with thread segment 3, uniform bottom inner sleeve 1 is surrounded with six elastic sheet metals 4, and six elastic sheet metals 4 form a horn-like structure expanded outwardly；Described overcoat 2 includes body 5, and body 5 top is tapped pipe, bottom is the expansion pipe that adapts of the horn-like structure constituted with six elastic sheet metals 4.

Described inner sleeve 1 and overcoat 2 upper end are equipped with handle 6.Thus structure, the handle put outward facilitates positioning and locking, and the handle inside put is convenient provides moment to bolt, is undertaken unscrewing or screwing by bolt.

Described elastic sheet metal 4 inner surface is provided with anti-skidding protruding 7.Thus structure, increases the friction with threaded bolt contacts, it is prevented that skid.

Being provided with one section of cavity in described inner sleeve 1 bottom, many round bars 8 are arranged in cavity and round bar magnetic is contrary with the magnetic of cavity bottom.Thus structure, when operation, partial cylinder bar can extend in the groove of dormant bolt, is matched for clamping tightly by inside and outside, it is achieved bolt unscrews or screws.

Described elastic sheet metal 4 is provided with magnetisable material, and magnetisable material makes elastic sheet metal 4 mutual exclusion.Elastic sheet metal 4 is thus made to remain open configuration under non-duty, it is prevented that after long-term extruding, elastic sheet metal loses the elasticity opened and makes troubles to operation.

During work, the horn-like structure alignment dormant bolt first the six of this device elastic sheet metals 4 constituted, make round bar 8 extend in the groove of dormant bolt, handle 6 on turn overcoat 2, the expansion pipe making body 5 bottom moves down, and is matched for clamping tightly by inside and outside, it is achieved bolt unscrews or screws.
