A second connection hole 12 (e.g., an M3 screw hole) is provided at the center of the top of each tenon. Connection holes corresponding to the first and second connection holes 9 and 12 are provided at both ends of the connection gasket, respectively. Screws (e.g., M3 screws) are used to fasten the ends of the connection gasket to the corresponding first and second connection holes 9 and 12 to achieve a fixed connection.
