Abstract

The utility model discloses an inner hexagon wrench, which belongs to the technical field of withdrawal tools. The wrench comprises a metal rod body which is bent into a right angle; a head end of a bending section of the mental rod is matched with an inner hexagon screw; a rubber ring is tightly matched with the bending section and the extending sections; and the head ends of the metal rod are bare. The wrench has the characterizes of skid resistance, abrasion resistance, good hand feeling, construction speed increase, long service life and the like, and the metal rod body is difficult to fall off due to the viscose forming rubber ring.

Description

Inner hexagon spanner

Technical field

The utility model discloses inner hexagon spanner, belong to the extracting tool technical field.

Background technology

The present L type inner hexagon spanner that generally uses, structure are that the metal bar bending by a regular hexagonal section constitutes, and the termination of its bend is the position that cooperates with soket head cap screw, and the chamfering of termination can conveniently be inserted nut.Yet this inner hexagon spanner still exists the use defective: the first, hold hexagon metal bar when surface, and feel is bad, and exerts all one's strength and skid easily; Second, because the inner hexagon spanner specification is many, it is also comparatively convenient to use for the inner hexagon spanner of big specification, and use for the inner hexagon spanner of those small dimensions very inconvenient, holding rod is too thin, although adopted hexahedral shape, adds that the area of each face is less because the metal surface is smooth, cause holding when the wrenching bar gymnastics is done and skid easily, cause wasting time and energy of operation construction.

Summary of the invention

The utility model is at the deficiencies in the prior art, and it is a kind of easy to use that purpose is to provide, good hand touch, and cost increases low inner hexagon spanner.

For reaching the purpose of this utility model, the technical scheme that is adopted is: a kind of inner hexagon spanner, comprise a rectangular metal barred body of bending, match with soket head cap screw in the termination of its bend, it is characterized in that: described bend and extension thereof tighten and are equipped with rubber ring, and expose the termination.

This use is novel further to be set to:

The whole regular hexagon cylinder that adopts the diameter equalization of described metal barred body.

The bend of described metal barred body and the diameter of extension thereof are less than the diameter of termination.

The cross sectional shape of described bend and extension thereof adopts a kind of in circle, triangular, square, the regular hexagon.

In sum, the utility model advantage compared with prior art is: anti-skidding, wear-resisting, feel is good, has improved speed of application; The metal barred body is by viscose glue moulding rubber ring difficult drop-off, long service life.

The utility model is described in further detail below in conjunction with description of drawings and specific embodiment:

Description of drawings

Fig. 1 is the overall structure schematic diagram of first kind of embodiment of the utility model;

Fig. 2 is the overall structure schematic diagram of second kind of embodiment of the utility model.

The specific embodiment

Embodiment one:

As shown in Figure 1, a kind of inner hexagon spanner comprises a rectangular metal barred body 1 of bending, and termination 12a, the 12b of its bend 11 match with soket head cap screw.Naturally the rounding 14 that forms when bend 11 is provided with bending.Bend 11 and extension 13 thereof tighten and are equipped with rubber ring 2, and expose

termination

12a, 12b, this rubber ring 2 is that metal barred body 1 adopts adhesive means to carry out viscose glue, treat to cut off redundance behind the rubber cooling forming, promptly form and metal barred body 1 close-fitting rubber ring 2, this rubber ring 2 adopts anti-skidding, high-abrasive material making.Wherein this metal barred body 1 integral body adopts regular hexagon cylinder of diameter equalization.The top 12a of the termination 12a of metal barred body 1 ^/Regular hexagon for the band chamfering; The top 12b of termination 12b ^/For the hexahedron structure of axial rounding, can handle the special soket head cap screw in some angle positions, because termination 12b can multi-angle change.

Embodiment two:

As shown in Figure 2, the basic structure of present embodiment is identical with embodiment one, and the bend 11 of different is described metal barred body 1 and the diameter of extension 13 thereof help saving metal material less than the diameter of

termination

12a, 12b, reduce cost.Bend 11 and extension 13 thereof that this section diameter is less relatively are provided with rubber ring 2, and rubber ring 2 installation methods are the viscose glue technology with embodiment 1.The cross sectional shape of described bend 11 and extension 13 thereof adopts a kind of in circle, triangular, square, the regular hexagon.

The utility model belongs to a kind of improvement of structure, and embodiment one, 2 two kind of scheme have been enumerated, both can on existing inner hexagon spanner, add rubber ring and reach anti-skidding, wear-resisting by viscose glue, feel is good, the effect of raising speed of application etc., also can produce a kind ofly separately, save metal material, cost-effective inner hexagon spanner in the time of effect such as its realization is anti-skidding, wear-resisting again as embodiment two described structures.

Wherein a kind of structure that Fig. 1, inner hexagon spanner structure illustrated in fig. 2 are only enumerated for the utility model; be termination 12a, the 12b of metal barred body described in the utility model when being structure such as the hexagon of band chamfering or hexagonal blossom type, all belong to the claimed scope of the utility model.
