<p>The tool has a push rod (4) and a circular suction cup (5) placed at an end of the push rod to selectively maintain a module (3). A support unit (41) is placed at the same end of the push rod so as to be supported on the module. A bearing surface (42) of the support unit contacts with the module to leave corners of the module to be free. The module includes a flat surface, and the bearing surface is formed to be inscribed in a cavity of the module. The bearing surface is limited by a circular contour.</p> |
