[0027] Example 2

[0028] Reference Figure 1 and Figure 2 , the guide rod 3 is provided with mounting assembly 10, the mounting assembly 10 includes mounting block 12 and mounting slot 13, the mounting block 12 is fixed on the end of the guide rod 3 away from the support mechanism 1, the mounting slot 13 is opened on the surface of the mounting block 12, the slot of the mounting slot 13 is upwardly arranged, for improving the installation stability of the positioning plate 15;

[0029] Reference Figure 2 、 Figure 3 and Figure 4The installation assembly 10 is provided with an adjusting assembly 11 for adjusting the position of the movable tube 6, used for controlling the distance between the brush plate 5 and the walking rudder body 2. The adjusting assembly 11 comprises a spring piece 14, a positioning plate 15, a through hole 16, a fixing cylinder 17, an adjusting screw 18 and an adjusting nut 19. The spring piece 14 is movably sleeved on the surface of the guide rod 3 between the positioning plate 15 and the movable tube 6. The two ends of the spring piece 14 are fixedly connected with the surface of the positioning plate 15 and the movable tube 6, respectively. The positioning plate 15 is clamped in the inside of the installation slot 13. The through hole 16 is arranged in the middle of the positioning plate 15. The fixing cylinder 17 is fixed on the side of the upper collecting frame 8 away from the walking rudder body 2. One end of the adjusting screw 18 is movably arranged in the inside of the fixing cylinder 17. Here, the main purpose is to make the adjusting screw 18 be able to stretch and retract while driving the upper collecting frame 8 to move. The purpose of stretching and retracting is to separate the through hole 16 on the positioning plate 15, so as to facilitate the removal of the mounting plate 7 and the brush plate 5. The other end of the adjusting screw 18 extends to the other side of the positioning plate 15 after passing through the fixing cylinder 17 and the through hole 16. The adjusting nut 19 is threadedly sleeved on the surface of the adjusting screw 18. The surface of the adjusting nut 19 is attached to the side of the positioning plate 15 away from the upper collecting frame 8. When operating, first, the adjusting screw 18 is elongated to pass through the through hole 16. Then, the adjusting nut 19 is threadedly sleeved on the surface of the adjusting screw 18. Continuous rotation drives the upper collecting frame 8 to move towards the positioning plate 15. The movement of the upper collecting frame 8 drives the brush plate 5 to move towards the positioning plate 15 through the mounting plate 7. The movement of the adjusting screw 18 can control the distance between the brush plate 5 and the walking rudder body 2. In this way, the brush plate 5 can be matched with walking rudder bodies 2 of different sizes, and the distance between the brush plate 5 and the walking rudder body 2 can be accurately positioned.

[0030] The above is one operation mode. If the brush plate 5 needs to be continuously attached to the surface of the walking rudder body 2, the adjusting nut 19 is removed from the adjusting screw 18. Then, under the elastic force of the spring piece 14, the spring piece 14 drives the upper collecting frame 8, the mounting plate 7, the lower collecting frame 9 and the brush plate 5 to move by pushing the movable tube 6, so that the brush plate 5 is tightly attached to the surface of the walking rudder body 2. This operation is another movement mode of the brush plate 5. The two modes can be selected according to actual use. The operation is simple.

[0031] In addition, when the upper collecting frame 8 and the lower collecting frame 9 need to be removed, first, the adjusting nut 19 is removed from the adjusting screw 18, then the adjusting screw 18 is moved to be retracted into the fixed cylinder 17 and separated from the through hole 16, then the positioning plate 15 is moved upward to be removed from the mounting groove 13, then the spring member 14 and the movable tube 6 are moved to separate the movable tube 6 and the spring member 14 from the guide rod 3, the movable tube 6 is removed to take the upper collecting frame 8, the mounting plate 7, the lower collecting frame 9 and the brush plate 5 together from the guide rod 3, the effect of conveniently removing the upper collecting frame 8 and the lower collecting frame 9 to clean the impurities and dust particles in the interiors of the upper collecting frame 8 and the lower collecting frame 9, after cleaning, the reverse operation in the above manner is performed to restore the original position.

[0032] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
