Abstract

The utility model discloses a box spanner for quick elasticity of nut, its body include sleeve power pole and collet head two parts, and body cavity, collet head front end cavity is inside to be interior hexagonal structure, and the minimum circumference of interior hexagonal structure is greater than body cavity circumference, the surface cross -section of sleeve power pole is equilateral dodecagon structure. The utility model aims at providing a box spanner for quick elasticity of nut is exclusively used in lead screw and the quick elasticity of nut complex, also can be used for the quick elasticity of other nuts simultaneously.

Description

A kind of box spanner for the quick degree of tightness of nut
Technical field
The utility model belongs to hardware & tools field, is specially a kind of box spanner for the quick degree of tightness of nut.
Background technology
Spanner is a kind of conventional installation and removal instrument.Utilize lever principletwist bolt, screw, nut and other screw threads tightly hold opening or the trepanning of bolt or nut firmwarehand tools.Spanner is usually shaped with clamp holder portion and applies external force shank and apply external force in the one or both ends of shank, just can twist opening or trepanning that bolt or nut hold bolt or nut.During use, threadingly direction of rotation applies external force at shank, just can twist bolt or nut.
But when use spanner tightening nut, for coordinating of screw mandrel 80 as shown in Figure 1 and nut 90, the spinning in and out of simple use spanner are more difficult, and need to expend the more time, are unfavorable for quick repair.
Also be not directed to the special spanner that feed screw nut coordinates at present.
Utility model content
The purpose of this utility model is for above problem, provides a kind of box spanner for the quick degree of tightness of nut, is exclusively used in the quick degree of tightness of screw mandrel and nut screw connection, also may be used for the quick degree of tightness of other nuts simultaneously.
For realizing above object, the technical solution adopted in the utility model is: a kind of box spanner for the quick degree of tightness of nut, and its body (1) comprises sleeve power bar (101) and collet head (102) two parts, and body (1) hollow; Collet head (102) front end empty internal is interior hexagonal structure, and the smallest circumference of interior hexagonal structure is greater than the hollow peripheral of body (1); The outer surface cross section of described sleeve power bar (101) is equilateral dodecagon structure.
Further, the external diameter of described sleeve power bar (101) is less than the external diameter of collet head (102), and in two outer surface junction arc-shaped transition.
Further, the interior angular structure of the front end empty internal of described collet head (102) replaces with other nut configurations.
Further, the interior angular structure of the front end empty internal of described collet head (102) is Triangle ID or interior anistree structure.
The beneficial effects of the utility model: a kind of box spanner for the quick degree of tightness of nut of the utility model, is exclusively used in the quick degree of tightness of screw mandrel and nut screw connection, also may be used for the quick degree of tightness of other nuts simultaneously.
1, have employed box spanner, turn can be carried out to the nut on screw mandrel more easily, avoid spanner to injure nut angular surface;
2, the power bar part of box spanner and ratchet spanner with the use of, degree of tightness can be realized fast, avoid common wrench in the process turning nut, need the problem of multiple conversions force direction.
3, for common nut tightness adjusting, adopt box spanner to be combined with ratchet spanner, need not be enclosed within screw mandrel, also can carry out quick despatch.
Accompanying drawing explanation
Fig. 1 is existing screw mandrel and nut screw connection structural representation.
Fig. 2 is the schematic diagram adopting the utility model spanner to carry out degree of tightness.
Fig. 3 is that perspective view is looked on the utility model left side.
Fig. 4 is that perspective view is looked on the utility model right side.
Described in figure, label character is expressed as: 70, ratchet spanner; 80, screw mandrel; 90, nut;
1, body; 101, sleeve power bar; 102, collet head; 103, inner nut head; 104, through hole.
Detailed description of the invention
The technical solution of the utility model is understood better in order to make those skilled in the art; below in conjunction with accompanying drawing, the utility model is described in detail; the description of this part is only exemplary and explanatory, should not have any restriction to protection domain of the present utility model.
As in Figure 2-4, concrete structure of the present utility model is: a kind of box spanner for the quick degree of tightness of nut, and its body 1 comprises sleeve power bar 101 and collet head 102 two parts, and body 1 hollow; Collet head 102 front end empty internal is interior hexagonal structure, and the smallest circumference of interior hexagonal structure is greater than the hollow peripheral of body 1; The outer surface cross section of described sleeve power bar 101 is equilateral dodecagon structure.
Preferably, the external diameter of described sleeve power bar 101 is less than the external diameter of collet head 102, and in two outer surface junction arc-shaped transition.
Preferably, the interior angular structure of the front end empty internal of described collet head 102 replaces with other nut configurations.
Preferably, the interior angular structure of the front end empty internal of described collet head 102 is Triangle ID or interior anistree structure.
During concrete use, body 1 is enclosed within screw mandrel 80, and makes the collet head 102 of body 1 aim at the nut 90 treating degree of tightness, collet head 102 is enclosed within nut 90, hold the sleeve head end of body 1, ratchet spanner is stuck in operation that sleeve power bar 101 exerts a force up and down, can degree of tightness be realized.
It should be noted that, in this article, term " comprises ", " comprising " or its any other variant are intended to contain comprising of nonexcludability, thus make to comprise the process of a series of key element, method, article or equipment and not only comprise which key element, but also comprise other key elements clearly do not listed, or also comprise by the intrinsic key element of this process, method, article or equipment.
Apply specific case herein to set forth principle of the present utility model and embodiment, the explanation of above example just understands method of the present utility model and core concept thereof for helping.The above is only preferred embodiment of the present utility model, should be understood that, due to the finiteness of literal expression, and objectively there is unlimited concrete structure, for those skilled in the art, under the prerequisite not departing from the utility model principle, some improvement, retouching or change can also be made, also above-mentioned technical characteristic can be combined by rights; These improve retouching, change or combination, or the design of utility model and technical scheme are directly applied to other occasion without improving, and all should be considered as protection domain of the present utility model.
