Detailed Description

Now that the structural content and the characteristics of the present invention will be described in detail with reference to the drawings, it is believed that the present invention and the effects thereof will be further understood.

Please refer to fig. 1 to 3, the sleeve tool of the present invention mainly uses the indication mark 11 (the indication mark of the present invention is a groove as its optional implementation state, it can also be a scale or is different color display scale with the body) on the outer diameter of a body 1, the indication mark 11 is set in one or more than one equal division way, a workpiece socket hole 2 is set on one end of the body 1, the workpiece socket hole 2 contains a plurality of first sockets 3 with sharp corners on the top and a plurality of second sockets 4 with R corners on the top, wherein:

a plurality of first nesting parts 3, wherein two sides of each first nesting part 3 are provided with a first force application surface 31 and a second force application surface 32, and the joint of the top ends of the first force application surface 31 and the second force application surface 32 forms a sharp angle;

a plurality of second nesting parts 4, wherein the top end of each second nesting part 4 is an arc section 41 with an angle R, two sides of each arc section 41 are respectively provided with a third force application surface 42 and a fourth force application surface 43, each third force application surface 42 is connected with the first force application surface 31 of each first nesting part 3, and each fourth force application surface 43 is connected with the second force application surface 32 of each first nesting part 3;

the first engaging portion 3 and the second engaging portion 4 are engaged with each other, so that the plurality of first engaging portions 3 and the plurality of second engaging portions 4 are engaged with each other to form an inner diameter of the workpiece engaging hole 2, and an inner diameter H formed from a center point of the second engaging portion 4 to a top end of the arc section 41 is larger than an inner diameter H1 formed from a center point of the first engaging portion 3 to a top end of the first engaging portion 3.

Referring to fig. 4, it is shown as an optional embodiment of the present invention, wherein, when the nut 5 with a smaller size of the continuous distance is to be disassembled or locked (the size of the common metric nut is 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm., and the size of the continuous distance defined by the present invention is 12mm, 13mm is 1 continuous distance, 14mm, 15mm is 1 continuous distance, 16mm, 17mm is 1 continuous distance, and so on), the indication mark 11 is aligned with the nut 5 and sleeved into the first engaging portion 3 (the indication mark 11 of the present invention is aligned with the first engaging portion 3 as an optional implementation state, and of course, the indication mark 11 can be set as an implementation state aligned with the second engaging portion 4 as required), the body 1 of the socket tool is rotated, and at this time, the first force applying surface 31 and the second force applying surface 32 of the first engaging portion 3 are applied with a large force applying area, the nut 5 can be disassembled or locked.
