A detachable combined toy top is disclosed. The toy top includes a main top and a subsidiary top, wherein the main top has a complete top structure including a top cap, a main top piece, a top axle sleeve and a top tip, and the subsidiary top includes a subsidiary top piece, an axle sleeve structure and a top tip. The subsidiary top has an elastic structure on its top, and the main top is actively connected to the top of the subsidiary top; by the elastic structure, when obstructed during spinning, the main top can be detached from the subsidiary top and ejected out, such that the two tops can spin on themselves separately. As a result, the top can divide into two in a game, which substantially improves its attack capability and the chance to win.
