Specifically, the mounting base 2 is cylindrical, and a positioning column 22 is disposed at one end thereof. Reference column 22 is located the centre of a circle department of mount pad 2 bottom surface, of course, sets up reference column 22 in other positions of mount pad 2 bottom surface and also all can realize the utility model discloses. After the wiping head 1 is covered on the positioning column 22, a shape matched with the special-shaped hole is formed. When cleaning a profiled hole, a certain pressure is given to the mounting block 2 and the mounting block 2 is rotated. Because the wiping head 1 can elastically deform, under the pressure of the positioning column 22, the wiping head 1 can fully contact with the special-shaped hole, so that the special-shaped hole can be cleaned. The cleaning head 1 is wrapped on the positioning column 22 to form a positioning hole, and the aperture of the positioning hole is slightly smaller than that of the positioning column 22, so that the cleaning head 1 can be fixed on the positioning column 22 after being installed on the positioning column 22. However, during the installation rotation, the wiping head 1 may still slide relative to the installation seat 2, so that the wiping head 1 is further fixed by the fastening nut 3.

Referring to fig. 1, 2 and 3, as a preferred technical solution, the side wall of one end of the mounting seat 2 is provided with an external thread 21 for connecting the fastening nut 3; one end of the fastening nut 3 extends radially inwards to form a circle of inner ring 31, and the hollow part of the inner ring 31 forms the avoidance hole; the edge of the wiping head 1 extends outwards in the radial direction to form a circle of flanges 11; after the fastening nut 3 is connected to the mounting base 2 via the external thread 21, the inner ring 31 clamps the flange 11 so that the wiping head 1 is clamped and fixed to the mounting base 2. The inner ring 31 forms a relief hole through which the portion of the wiping head 1 intended for wiping a profiled hole can pass, but not through which the flange 11 can pass. When assembling, positioning post 22 is inserted into the positioning hole, fastening nut 3 is tightened, and flange 11 is tightly clamped by inner ring 31 and mounting seat 2, so that when mounting seat 2 is rotated, wiping head 1 does not slide relative to mounting seat 2, thereby cleaning the special-shaped hole better.
