The connection port fixing jigs are aligned at a front and a rear part of a center of an installation frame(210). The installation frame installed at a lower part of the connection port fixing jig. The punching device is connected with the installation frame. The plural punching pins of the punching device pressurize a pipe connection of a rotary plate unit partially. The rotary plate unit is mounted on the connection port fixing jig. The connection port supporting jig is movably connected with a center part of the installation frame. The rack fixing jig is connected at both upper surfaces of the installation frame around the connection port fixing jig. The connection pipe is curved.
