Description
Technical field
The utility model relates to tool equipment field, particularly relates to a kind of fixed sleeve spanner.
Background technology
Bolt is the conventional machine components removably connected.
At present, in order to increase the fastening performance of bolt and prevent clamp nut from loosening, usually take a bolts to join two nuts together to use, nut below plays the role of fastening clamp nut, also can increase the back of the body preventing clamp nut from loosening female on clamp nut.All use box spanner to be enclosed within nut when tightening or loosen nut, the box spanner handle part that hits with a hammer is by nut tightening or loosen.Box spanner does not support and standing part.Need in use a people with hand steered another people of front end of box spanner handle of living hit with a hammer box spanner handle afterbody thus realize tightening or loosening work of the female and clamp nut of the back of the body.If box spanner is held up in not employment, not easily completing the work tightening or unload loose-back spiral shell and clamp nut, box spanner easily occurring by hitting the problem flown, hit the box spanner that flies once beat on the person, casualty accident can occur.
And needing the hand steered box spanner of personnel to carry out operating and can produce following problem: 1. the personnel of the box spanner handle afterbody that hits with a hammer can injure hand or arm that (shake wound) holds up box spanner handle front-end person who by a crashing object when misoperation; 2. waste of manpower resource, fastening or loosen clamp nut and need to coordinate together with two people in time carrying on the back female just can complete.
Therefore, there is the technical problem of box spanner not easily one man operation when installing or removing bolt with double nut in prior art.

Detailed description of the invention
The utility model embodiment by providing a kind of fixed sleeve spanner, in order to solve the technical problem of the box spanner that exists in the prior art not easily one man operation when installing or removing the bolt with double nut.
Please refer to Fig. 1, the partial sectional view of the fixed sleeve spanner that Fig. 1 provides for the utility model embodiment, the utility model embodiment provides a kind of fixed sleeve spanner, comprising:
Handle 1;
Driving end 2, is connected with described handle 1, and described driving end 2 has screw hole 3 away from one end of described handle 1, and described screw hole 3 is through hole, is provided with the first screw thread in described screw hole 3;
Fixed screw 4, be arranged in described screw hole 3, described fixed screw 4 has second screw thread corresponding with described first screw thread, and described fixed screw is fixed with elastic rubber fitting 5 away from one end of the nut of described fixed screw;
Inner supporting body 7, be arranged on described driving end 2, described inner supporting body 7 is for having externally threaded hollow cylinder;
Outer support 8, described outer support 8 is for having the hollow cylinder of the internal thread corresponding with described external screw thread, and described outer support 8 is by described internal thread and to be describedly externally threadedly connected on described inner supporting body.
Please continue to refer to Fig. 1, the fixed sleeve spanner that the present embodiment provides is by handle 1, and driving end 2, screw hole 3, fixed screw 4, elastic rubber fitting 5, elastic mounting screw 6, inner supporting body 7, outer support 8 eight part forms.
Please continue to refer to Fig. 1, in the present embodiment, the handle 1 of described fixed sleeve spanner, driving end 2, inner supporting body 7 three part are that the one-tenth of one crosses the L shape of coming, certainly, by the introduction of the present embodiment, handle 1, driving end 2, inner supporting body 7 three part according to actual conditions, can be set to other suitable shapes by the technical staff belonging to this area, to meet the demand of actual conditions, do not limit at this.
Please continue to refer to Fig. 1, in the present embodiment, handle 1 is flat elongate strip, user-friendly, circle drum driving end 2 in one end of flat elongate strip, please continue to refer to Fig. 2, the top view of the fixed sleeve spanner that Fig. 2 provides for the utility model embodiment, driving end 2 outline is circle drum, center is hexagon through hole, a threaded through hole screw hole 3 of circle is had in hexagon through hole one side, certainly, in other embodiments, the center of driving end 2 can be dodecagon through hole, also can be that other shapes are as triangle through hole, pentagon through hole etc., do not limit at this, be as the criterion with the needs meeting actual conditions.
Please continue to refer to Fig. 1 and Fig. 2, in the present embodiment, fixed screw 4 is threaded connection and is fixed on screw hole 3; In order to ensure that fixed screw 4 is connected with elastic rubber fitting 5 is stable, in the present embodiment, the screw terminal of fixed screw 4 there is the elastic rubber fitting 5 be connected and fixed by elastic mounting screw 6, of course, in other embodiments, also can be connected by other suitable modes, just repeat no more at this.
Please continue to refer to Fig. 1 and Fig. 2, in the present embodiment, driving end 2 is hollow cylinder inner supporting body 7 perpendicular to the one side of flat elongate strip; Inner supporting body 7 has screw thread at the outer surface of hollow cylinder, and be threaded connection outer support 8, outer support 8 is hollow cylinders, and inner surface has screw thread, is threaded connection on inner supporting body 7.
In actual use, all adopt two nuts together to use for set bolt on such as oil pumping unit base, nut is below clamp nut, above be that the back of the body that prevents clamp nut from loosening is female.The back of the body on tighten or loosen time female screws out outer support 8, and the height after making it screw out is identical with clamp nut height below, and at this moment the one side of fixed sleeve spanner band supporter is enclosed within clamp nut, driving end 2 has also just been enclosed within back of the body mother.Be tightened screw 4, the back of the body that elastic rubber fitting 5 is held out against above is female, such fixed sleeve spanner is just fixed on back of the body mother, at this moment get final product a people make the to hit with a hammer handle 1 of fixed sleeve spanner can realize tightening or loosen standby female work, fixed screw 4 of outwarding winding after using can take off fixed sleeve spanner.When clamp nut below needing to tighten or loosen, by fixed sleeve spanner conversely with not having the one side of supporter to be enclosed within clamp nut, then tighten the operation that fixed screw 4 can implement to tighten or loosen.
