Abstract

The utility model relates to a wrench socket which comprises a socket body, wherein the socket body is provided with wrench openings for screwing or unscrewing a nut; each wrench opening is gradually reduced from the caliber of the end surface to the caliber of the root part to form a frustum; the taper of each frustum-shaped wrench opening is 1: 5-1: 30. According to the wrench socket, each wrench opening is gradually reduced from the caliber of the end surface to the caliber of the root part, so that the nut which is manufactured in a nonstandard manner is screwed or unscrewed, the slip phenomenon generated when the nut is screwed or unscrewed is avoided, and thus the nut is relatively easy and rapid to operate; by using the two wrench openings with different calibers in the socket body, the nuts in different specifications can be screwed or unscrewed, and the practicability of equipment is increased.

Description

A kind of wrench socket

Technical field

The utility model relates to a kind of nut tightening device, particularly a kind of wrench socket.

Background technology

Box spanner is generally by a plurality of sleeves with hexagon ring or 12 jiaos of holes and be furnished with the multiple accessories such as handle, extension bar and form, and is specially adapted to twist status very narrow and small or cave in very bolt or the nut of depths.But, existing box spanner is only applicable to tightening or unscrewing by the nut of standard making mostly, can not be applicable to tightening or unscrewing by the nut of non-standard making, and people 80% nut is all used by non-standard making in real work, so, use existing box spanner to tighten or unscrew nut and easily produce skidding.

Summary of the invention

The technical problems to be solved in the utility model is for the deficiencies in the prior art, proposes a kind of being difficult for to skid, and can tighten or unscrew the wrench socket of nut.

The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of wrench socket, comprise sleeve body, in sleeve body, be provided with and tighten or unscrew the mouth of pulling that nut uses, be characterized in: the described mouth of pulling reduces to form taper type by end face bore gradually to its root bore, and the tapering that taper type is pulled mouth is 1:5～1:30.

The technical problems to be solved in the utility model can also be come further to realize by the following technical programs, and described sleeve body is provided with two kinds of different bores and pulls mouth.

The technical problems to be solved in the utility model can also be come further to realize by the following technical programs, and the tapering that described taper type is pulled mouth is 1:10～1:15.

The technical problems to be solved in the utility model can also be come further to realize by the following technical programs, and the cross section of described sleeve body is hexagon.

Compared with prior art, the utility model utilization is pulled mouth and is reduced gradually by end face bore to its root bore the taper type forming, can realize tightening or unscrewing by non-standard making nut, avoided the skidding occurring when tightening or unscrew nut, making the operation of nut become is more prone to, fast; Utilization is arranged on two kinds of different bores in sleeve body and pulls mouth, can realize the tightening or unscrewing of different size nut, and has increased the practicality of equipment.

Accompanying drawing explanation

Fig. 1 is top view of the present utility model;

Fig. 2 is that the A-A of Fig. 1 is to schematic diagram.

The specific embodiment

A wrench socket, comprises sleeve body 1, is provided with and tightens or unscrew the mouth of pulling that nut uses in sleeve body 1, and described pulling mouthful reduces to form taper type by end face bore to its root bore gradually, and the tapering that taper type is pulled mouthful is 1:5～1:30.Described sleeve body 1 is provided with two kinds of different bores and pulls

mouthfuls

2,3; The tapering that described taper type is pulled mouth is 1:10～1:15; The cross section of described sleeve body 1 is hexagon.The described bore ecto-entad of pulling mouth reduces to be taper type gradually; The tapering that taper type is pulled mouthful is set to 1:10～1:15, has better realized the tightening or unscrewing of non-standard making nut, and has avoided the generation of skidding.Pull the two ends that

mouth

2,3 is separately positioned on sleeve body, increased the practicality of wrench socket for described two kinds.

Claims

1. a wrench socket, comprises sleeve body, is provided with and tightens or unscrew the mouth of pulling that nut uses in sleeve body, it is characterized in that: described pulling mouthful reduces to form taper type by end face bore to its root bore gradually, and the tapering that taper type is pulled mouthful is 1:5～1:30.

2. wrench socket according to claim 1, is characterized in that: described sleeve body is provided with two kinds of different bores and pulls mouth.

3. wrench socket according to claim 1, is characterized in that: the tapering that described taper type is pulled mouth is 1:10～1:15.

4. wrench socket according to claim 1, is characterized in that: the cross section of described sleeve body is hexagon.
