When not in use, the baffle can be slid into the installation slot and limited by the spring sheet to ensure the cooperation between the first heat dissipation hole and the second heat dissipation hole, so as to control the ventilation volume in the shell; The push plate provided drives the sliding column to slide along the circular slide groove, and the sliding column drives the long plate to move, and the long plate drives the guide rod to slide along the rectangular slide groove, and the long plate drives the hollow column to move, and the hollow column drives the annular ink pad, so that the annular ink pad contacts the wall, and the annular ink pad leaves marks of the screw drilling positions on the wall, so that the screw installation positions can be conveniently marked during installation, and the holes will not be distorted after marking, which solves the problem in the prior art that the workers are prone to inaccurate measurements and distorted holes, resulting in the misalignment of the screws and the holes during installation, and the need to re-drill.
