Specifically, the positioning component 10 includes a circular ring 11, and at least three groups of pressing mechanisms 20 are uniformly arranged on the circular ring 11 along the circumference. The upper side of the circular ring 11 is provided with a track 12 in parallel, the track 12 is in a circular ring structure, and the section of the track is circular. More specifically, the track 12 is connected with the ring 11 through a plurality of cylinders 14, and the plurality of cylinders 14 are uniformly arranged along the circumference of the ring 11.
Specifically, the pressing mechanism 20 includes a top plate 21, the top plate 21 is located outside the circular ring 11, and the top plate 21 is movable in a normal direction of the circular ring 11. Ring 11 corresponds hold-down mechanism 20 and all is equipped with connecting plate 13, and ring 11 cross-section is the rectangle, and 11 inner walls of ring are located to connecting plate 13, and roof 21 swing joint has screw rod 22, and screw rod 22 passes ring 11 and connecting plate 13 simultaneously, and the screw rod 22 cooperation is equipped with the nut, utilizes this nut locking screw rod 22. When in use, the screw 22 and the street top plate 21 can be rotated from the inside of the circular ring 11 to tightly push or release the inner wall of the circular pipe 3.
Preferably, the outer surface of the top plate 21 is a circular arc surface, so that the outer surface can be better attached to the inner walls of the circular tubes 3 with different diameters. The axis of the arc surface is parallel to the axis of the circular ring 11, in order to ensure the parallel of the circular ring 11 and the axis of the circular tube 3, the length of the top plate 21 along the axis direction of the arc surface is greater than 100mm, when the top plate 21 is completely attached to the inner wall of the circular tube 3 along the length direction, the axes of the circular ring 11 and the track 12 are all kept parallel to the axis of the circular tube 3, and therefore the plane of the track 12 is ensured to be perpendicular to the axis of the circular tube 3.
Specifically, the rotating component 30 includes a sliding block 31 and a rotating plate 32 hinged to the sliding block 31, the sliding block 31 is slidably connected to the rail 12, a rotation axis of the rotating plate 32 is parallel to a plane of the rail 12 and perpendicular to a normal of the rail 12, the rotating plate 32 is provided with a fixing ring 33, the fixing ring 33 is provided with at least one locking screw 34, an axis of the fixing ring 33 is perpendicular to the rotation axis of the rotating plate 32, the fixing ring 33 is used for penetrating the sander 1, and the locking screw 34 is used for pressing the sander 1 to fix the sander.
