In order to better let children understand real ships, toy developers often install propellers at the bottom of ship toys for decoration, making them look more realistic and practical. However, the propellers of existing ship toys are often fixed, and such a structural design cannot achieve a real interactive experience of propeller rotation. Therefore, those skilled in the art have developed rotatable propellers. However, at present, ship toys with rotatable propellers often use manual rotation of the propellers or drive motors to rotate the propellers. The structural design of manual rotation of the propellers has the problems of inconvenient rotation of the propellers and inability to rotate automatically.
