Abstract

The utility model relates to a wrench, which comprises a sleeve and a handle which is fixedly connected with the outer wall of the sleeve and is perpendicular to the wall of the sleeve, wherein the sleeve is sleeved with a first internal sleeve, a second internal sleeve and a third sleeve inside in turn, the upper end of each internal sleeve is provided with a flange, wherein the outer diameter of the flange of the first internal sleeve is larger than the inner diameter of the sleeve, the outer diameter of the flange of the second internal sleeve is larger than the inner diameter of the first internal sleeve, the outer diameter of the flange of the third sleeve is larger than the inner diameter of the second internal sleeve, and the lower ends of the sleeve, the first internal sleeve, the second internal sleeve and the third internal sleeve are level, the sleeves are arranged in layers to form sleeves with different types, and are arranged from inside to outside by size. Therefore, the sleeve is only aligned to a screw or nut which needs to be disassembled when in use, and the suitable sleeve can be adopted, thus, the use is extremely convenient, the carrying is convenient, the time and labor are saved, the raw material is saved, and the wrench has substantive characteristics and advancements.

Description

A kind of spanner

Technical field

The utility model relates to a kind of dismantling device of screw-nut, but specifically a kind of spanner.

Background technology

Spanner is one of people's instrument relatively commonly used in the daily life, and it can be used for loading and unloading screw-nut etc., and is time saving and energy saving, uses also convenience very.But common spanner generally can only be finished the dismounting to a kind of model screw or nut at present, when the screw-nut of different model is dismantled, need a plurality of spanners of mating wanted with it, be unfavorable for like this carrying and being equipped with, make spanner simultaneously and need material, then consumptive material is many to make the spanner of different model respectively, and manufacturing cost improves, and is unfavorable for promotion and application.

Summary of the invention

The purpose of this utility model provides a kind of spanner of easy to use, one-object-many-purposes.

For achieving the above object, the utility model is by the following technical solutions:

A kind of spanner described in the utility model, comprise sleeve, the handle of fixedlying connected with sleeve outer wall, handle is vertical with sleeve wall, be with first inner sleeve in the described sleeve successively, be with second inner sleeve in first inner sleeve, be with the 3rd inner sleeve in second inner sleeve, the upper end of each inner sleeve is equipped with ring flange, the external diameter of the ring flange of first inner sleeve is greater than the internal diameter of sleeve, the external diameter of the ring flange of second inner sleeve is greater than the internal diameter of first inner sleeve, and the external diameter of the ring flange of the 3rd inner sleeve is greater than the internal diameter of second inner sleeve, sleeve, first inner sleeve, the lower end of second inner sleeve and the 3rd inner sleeve flushes.

As a kind of improvement, be respectively equipped with chute on the inwall of described sleeve, first inner sleeve and second inner sleeve, the upper end of chute is provided with the retaining head, the outer wall lower end of first inner sleeve, second inner sleeve and the 3rd inner sleeve be respectively equipped with sleeve, first inner sleeve and the second inner sleeve inwall on the slide block that cooperatively interacts of chute.

Owing to adopted technique scheme, described spanner is provided with the sleeve layering, make it the sleeve of different model, ecto-entad is arranged successively by size, makes in use, only needs sleeve is aimed at the screw or the nut of the dismounting of wanting, the sleeve which sleeve of suitable which model just decided with, use convenience very, and be easy to carry, time saving and energy saving, save raw material, had substantial characteristics and progress.

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is the utility model user mode reference diagram.

The specific embodiment

The utility model will be further described below in conjunction with the drawings and specific embodiments.

A kind of spanner, comprise sleeve 1, the handle 2 of fixedlying connected with sleeve 1 outer wall, handle 2 is vertical with sleeve wall, be with first inner sleeve 3 in the described sleeve 1 successively, be with second inner sleeve 4 in first inner sleeve 3, be with the 3rd inner sleeve 5 in second inner sleeve 4, the upper end of each inner sleeve is equipped with ring flange, the external diameter of the ring flange of first inner sleeve 3 is greater than the internal diameter of sleeve 1, the external diameter of the ring flange of second inner sleeve 4 is greater than the internal diameter of first inner sleeve 3, the external diameter of the ring flange of the 3rd inner sleeve 5 is greater than the internal diameter of second inner sleeve 4, sleeve 1, first inner sleeve 3, the lower end of second inner sleeve 4 and the 3rd inner sleeve 5 flushes, and can also have the 4th in the sleeve certainly, the 5th, the 6th or the like inner sleeve, as long as the internal diameter of sleeve 1 is enough big, just a plurality of inner sleeves can be set.

Be respectively equipped with chute 6 on the inwall of described sleeve 1, first inner sleeve 3 and second inner sleeve 4, the outer wall lower end that the upper end of chute is provided with retaining 7, the first inner sleeve 3, second inner sleeve 4 and the 3rd inner sleeve 5 be respectively equipped with sleeve 1, first inner sleeve 3 and second inner sleeve, 4 inwalls on the slide block 8 that cooperatively interacts of chute 6.

During use, sleeve is buckled on the screw of want dismounting or nut, the internal diameter of which sleeve is fit to the size of screw or nut, just uses which sleeve, and is simple and efficient.
