[0010] In order to ensure the stability of the installation of the tool;
[0011] As a further improvement of the above technical solution: the number of self-adapting clamping pieces is three, and when the axes of the two arc-shaped plates are collinear, the three self-adapting clamping pieces are arranged equidistantly around the axis of the arc-shaped plate.
[0012] The beneficial effect of the improvement is that the three self-adapting clamping pieces can stably support the paint roller, so that the tool is installed at the center of the circular tube column.
[0013] In order to stably clamp the paint roller on the circular tube column;
[0014] As a further improvement of the above technical solution: the axis of the pin shaft on the connecting seat is parallel to the axis of the arc-shaped plate.
[0015] The beneficial effect of the improvement is that when the tool is installed on a circular tube column with different diameters, the paint roller can stably adhere to the surface of the circular tube column under the support of the self-adapting clamping piece.
