The invention discloses a bathing device with selectable shower nozzles of multiple specifications. The bathing shower nozzles of multiple specifications are centralized in a box body, fixed on a rotating mechanism and driven to rotate by a direct current servo motor. After a user selects the bathing shower nozzle of the corresponding specification with a controller, the rotating mechanism starts to rotate until a sensor detects that the corresponding bathing shower nozzle has arrived at a bathing shower nozzle outlet; then the controller drives an electric push rod to forwards push the corresponding bathing shower nozzle to be separated from the rotating mechanism and combined with a bathing shower nozzle connector. The bathing device disclosed by the invention is tidy and uniform in structure, higher in attractiveness and stable and firm in structure; meanwhile, the use of the bathing device is clear and readily understood; a small number of manual steps are provided, and are simple and intuitive; therefore, the bathing device is higher in automation degree and better in user experience.

The invention relates to a plastic mold provided with telescopic splicing devices. The plastic mold comprises a mold body. The mold body comprises a connecting base plate and an outer arc-shaped protective plate located at the upper end of the connecting base plate. A first reinforcing rod, a second reinforcing rod and a third reinforcing rod are fixedly connected between the inner arc surface of the outer arc-shaped protective plate and the connecting base plate.
