When the vertical pole 2 is located between the two arc rods 9, the nut is screwed on the positioning bolt 12. After the connection, the inner clamping plate 6 and the outer clamping plate 7 clamp the vertical pole 2, that is, the vertical pole 2 is clamped in the carbon brush positioning piece 4, and the carbon brush positioning piece 4 is sleeved on the vertical pole 2.
[0028] In order to facilitate the connection and positioning of the carbon brush, the carbon brush positioning head 5 is connected to the inner clamping plate 6, and the carbon brush positioning head 5 can rotate.

[0029] The rotating connection structure 13 includes a first rotating component 14 and a second rotating component 15. The first rotating component 14 and the second rotating component 15 are combined to enable the carbon brush positioning head 5 connected to the inner clamping plate 6 to rotate in multiple directions.

One end of the spring 30 is connected to a positioning ball 31, and a radial through hole is provided on the positioning ball 31. The adjusting screw passes through the radial through hole of the positioning ball. At this time, the positioning ball 31 is located between the spring 30 and the side plate 27. Under the action of the reset force of the spring 30, the positioning ball 31 can apply a pushing force to the side plate 27. At this time, the carbon brush positioning head 5 moves toward the slip ring, and finally the carbon brush is pressed against the slip ring, thereby increasing the connection stability between the carbon brush and the slip ring.
[0030] To avoid excessive movement, a locking disk is screwed onto the adjusting screw 29. The locking disk is located on the outside of the side plate, that is, the side plate is located between the locking disk and the locking ball. At this time, the maximum flipping amount of the side plate is when it contacts the locking disk.

At this time, the second rotating assembly and the carbon brush positioning head 5 move on the horizontal plane, that is, the angle between the auxiliary transverse plates 20 and the square sleeve 16 is adjusted. When the first bolt 18 is tightened in the hole 17, the auxiliary transverse plates 20 above the square sleeve 16 are in contact with the square sleeve, and the nut is tightened on the first bolt 18, so that the angle between the auxiliary transverse plates 20 and the square sleeve 16 can be determined;

However, at this time, the planes where the inner vertical plates 23 and the outer vertical plates 24 are located are perpendicular to the plane where the auxiliary horizontal plate 20 is located. One end of the inner vertical plate 23 is fixed to the auxiliary vertical plate 21. A center hole 25 is arranged on the inner vertical plate 23 and the outer vertical plate 24.

When the second bolt 26 is located in the central hole 25, the angle between the carbon brush positioning head 5 and the auxiliary cross plate 20 is adjusted, that is, the angle between the inner vertical plate 23 and the outer vertical plate 24 is adjusted. At this time, the carbon brush positioning head 5 moves on the vertical plane, and the nut is tightened on the second bolt 26 to determine the angle between the carbon brush positioning head 5 and the auxiliary cross plate 20. Therefore, by combining the first rotating component 14 and the second rotating component 15, the carbon brush positioning head 5 can be rotated in multiple directions.
[0033] During implementation, the carbon brush positioning member 4 is sleeved on the column, and the column is located between the two arc rods 9. The position of the carbon brush positioning member 4 on the column is adjusted, the positioning bolt 12 is placed in the through hole 11, and the nut is screwed on the positioning bolt 12. The relative position of the carbon brush on the column can be roughly determined, and the rotating connection structure 13 is adjusted to determine the position of the carbon brush. When the first bolt 18 and the second bolt 26 are respectively located in the circular hole 22 and the center hole 25, that is, the angle between the square sleeve 16 and the auxiliary cross plate 20 and the angle between the inner plate 23 and the outer plate 24 are adjusted, and the nut is screwed on the first bolt 18 and the second bolt 26. The position and angle of the carbon brush are determined, and so on. The carbon brushes are connected to the inner clamping plate 6, which is suitable for various carbon brush applications.
