Description

[0001]
The present invention relates to a structure of a polygonal nut and a nut attaching / detaching tool, and in particular, the nut and the nut sleeve of the nut attaching / detaching tool are designed to be gradually reduced from one end to the other, and are used in combination with each other. Further, the present invention relates to a polygonal nut and a structure of a nut removing tool which can be used in combination with a general traditional nut and a nut removing tool.
[0002]
Existing sleeve spanners have many standards, and when it is necessary to turn the nut, a sleeve of the same standard as the nut must be used. However, it is not easy for the average person to know the specifications of these sleeves and nuts, and sometimes it can take half a day to find a sleeve of the same standard as the nut, and even you can not find it is there.
[0003]
At present, DIY is prevalent in a large number of products. When we ordinary people do DIY work, it may be necessary to use a combination of nut and sleeve spanner. However, in general households, when suddenly needed, it is not usually possible to find sleeves of the same standard and use them in combination, which often makes it difficult to complete the work smoothly. Alternatively, a lot of valuable time may be spent finding a sleeve of the same standard as the nut, or even an excessively large sleeve may be used without finding a sleeve of the same standard as the nut. In some cases the nuts were damaged and irreversible.
[0004]
In addition, at present, in the production of sleeves and nuts, a tolerance of 15 to 20 articles is allowed, and if one sleeve and nut just reaches the maximum value of the tolerance, the two cannot be tightly fitted, If used forcibly, the gap may be too large, causing wear of the sleeve and nut.
[0005]
The main object of the present invention is to solve the above-mentioned drawbacks and avoid the drawbacks, that is, according to the present invention, the nut is provided with a screw column of an appropriate length, and the outer diameter of the screw pillar is one end. More gradually toward the other end, and the width of the plurality of end surfaces provided on the outer peripheral surface of the above-mentioned screw also gradually decreases from one end toward the other end according to the gradually reducing outer diameter of the screw, and One force receiving surface is formed by annularly adjoining the plurality of end surfaces described above. Further, the nut sleeve of the nut attaching / detaching tool has a fitting tank of an appropriate depth inside thereof, the inner diameter of the fitting tank gradually decreases inward from the opening, and a plurality of the above-mentioned fitting tank inner walls are formed. The width of the wall is also gradually reduced inward from the open end with the contraction of the inner diameter of the fitting tank, and the above-mentioned plurality of walls are annularly adjacent to each other and can be joined to the receiving surface of the nut. A surface is formed.
[0006]
Another object of the present invention is to make it possible to use the above-mentioned nut and the nut attaching / detaching tool in combination and to use each of them in combination with the traditional nut and the nut attaching / detaching tool.
[0007]
Still another object of the present invention is to operate a design that gradually reduces from one end of the outer diameter of the nut to the other end of the nut to the head of the bolt, with a nut sleeve of a different standard nut attaching / detaching tool. So that they can be used in combination.
