[0023] The specific operation is as follows. When in use, the flange interfaces 403 are connected together through the fixing screws 404 with the flange interfaces 403 or the connecting water pipe 9. Through the threaded connection between the reinforcing nut 405 and the fixing screw 404, the connection of the flange interface 403 is strengthened.
