The camera unit is installed on the moving body to be rotated at a predetermined angle. The drilling unit includes a blade guide(124), a gear(127), a ball screw, and the blade. The blade guide is fixed at a rear end of the moving bar. The gear is installed on the moving bar to form a double structure with the moving bar. The ball screw is engaged with the gear. The blade is combined with the ball screw and moved straight along the ball screw. The moving bar is installed to be moved straight within a predetermined range. The drilling unit comprises a hydraulic cylinder and a powering unit. The hydraulic cylinder moves the moving bar straight. The powering unit rotates the moving bar.
