[0020] The left and right sides of the first fixed ring 2 and the second fixed ring 3 are movably connected with the first connecting rod 13, and the left and right sides of the movable ring 4 are movably connected with the second connecting rod 14. The first connecting rod 13 and the second connecting rod 14 are respectively movably connected to the adjacent vertical plates 11, and the vertical plates 11 and the bottom plate 10 are fixedly connected with a plurality of brushes 12 on one side away from the column 1. Two connecting plates 15 are provided at both ends of the first connecting rod 13 and the second connecting rod 14, and the plurality of connecting plates 15 are respectively fixedly connected to the first fixed ring 2, the second fixed ring 3, the movable ring 4 and the vertical plates 11. Pins 16 are movably penetrated near both ends of the first connecting rod 13 and the second connecting rod 14, and both ends of the pins 16 are fixedly penetrated through the adjacent connecting plates 15. The first connecting rod 13 and the second connecting rod 14 are both inclinedly arranged, and the upward angle between the first connecting rod 13 and the column 1 is an acute angle, and the downward angle between the second connecting rod 14 and the column 1 is an acute angle.

[0021] Working principle: The utility model is a ball-end polishing brush for removing burrs from the inner side of a conductor side hole. During use, the distance between the two vertical plates 11 is first adjusted according to the size of the aperture to be deburred. During this process, the threaded tube 6 is held and rotated. The threaded tube 6 rotates in the inner cavity of the bearing 5 and the outer side of the external thread 7. The threaded tube 6 moves relative to the column 1 under the action of the external thread 7. When it is necessary to increase the distance between the two vertical plates 11, the threaded tube 6 is rotated to make it move downward relative to the column 1 under the action of the external thread 7. During this process, the first connecting rod 13 and the second connecting rod 14 rotate at both ends with the adjacent pin shaft 16 as the center, and at the same time, the upward angle between the first connecting rod 13 and the column 1 increases, and at the same time, the downward angle between the second connecting rod 14 and the column 1 increases. The first connecting rod 13 and the second connecting rod 14 push the two vertical plates 11, thereby increasing the distance between the two vertical plates 11.

[0022] When the distance between the two vertical plates 11 needs to be reduced, the threaded tube 6 is rotated in the opposite direction to make it move upward relative to the column 1 under the action of the external thread 7. During this process, the first connecting rod 13 and the second connecting rod 14 rotate around the adjacent pin shaft 16 at both ends, and the upward angle between the first connecting rod 13 and the column 1 decreases, and the downward angle between the second connecting rod 14 and the column 1 decreases. The first connecting rod 13 and the second connecting rod 14 push the two vertical plates 11, thereby reducing the distance between the two vertical plates 11.

[0023] After the distance between the two vertical plates 11 is adjusted to be slightly smaller than the hole size, the column 1 is moved by the handle 9, and the column 1 is inserted into the hole to be deburred. At the same time, the column 1 is moved up and down and rotated to achieve the deburring effect. The bottom plate 10 removes burrs from the bottom of the hole. The device can remove burrs from the inner wall and bottom of the hole at the same time, can freely adapt to different hole sizes, is easy to use, and has a wide range of uses.
