In the above proposal, the rail seat 31 of the longitudinal guide rail 30 is detachably connected with the top frame surface of the unit element A, the rail seat 31 of the longitudinal guide rail 30 can be installed and fixed at different positions in the longitudinal direction, namely, the longitudinal direction on the unit element A of a long steel structural member, and the position displacement of the rail seat 31 of the longitudinal guide rail 30 in the longitudinal direction of the unit element A is convenient; in addition, the sliding arrangement of the transverse rail 20 on the longitudinal rail 30 ensures that the transverse rail 20 is displaced within the range of the longitudinal length of the longitudinal rail 30, and at the same time, the drill 10 can be displaced to the entire lateral direction of the unit piece a within the range of the longitudinal length of the longitudinal rail 30, so that when the rail seat 31 of the longitudinal rail 30 is installed at a certain position section in the longitudinal direction of the unit piece a, the drill bit 11 of the drill 10 can reach the drilling of all the rivet holes to be machined within the range of the lateral area within the longitudinal section, and then the rail seat 31 of the longitudinal rail 30 is displaced to the next longitudinal section to perform the drilling operation, thereby completing the machining of all the rivet holes on the unit piece a.
