The invention discloses a launching device which includes a main pipe, wherein a flip is arranged on the main pipe and near a pipe orifice of the main pipe or an outer part is arranged on the main pipe and connected with a trip valve arranged on the inner side of the main pipe. The launching device is characterized in that the one or more grooves are formed in the flip or the outer part; a pattern layer is arranged at the bottom of each groove; the groove is filled with drop rubber through a plastic drop technology until the groove notch is filled with the drop rubber. According to the invention, a groundbreaking technical scheme is adopted that the grooves are formed in the upper surface and the flip or the outer part of the launching device, patterns are arranged inside the grooves, and the grooves are filled with drop rubber through the plastic drop technology; the problems of pattern arrangement and cost are solved ingeniously without affecting the stability of the original launching device structure; the launching device provided by the invention is both aesthetic and economical with long service life; the upper surface of the launching device, sealed by drop rubber, is durable and not liable to be broken; the launching device has a broad market prospect.
