When the product is used, the upper cover body 12 is held by hands to move the product to an open place, the ball outlet range is determined according to the size of the place and the required ball outlet direction, and the poking block 44 is poked to adjust the ball outlet range. When the ball-out range is large, such as an outdoor lawn or a park, the shifting block 44 is shifted outwards, and when the ball-out range is small, such as a living room or a yard at home, the shifting block 44 is adjusted according to the size of the field. The dial 44 has a plurality of gears on its sliding path, and the dial 44 is toggled to reach the set gear with significant resistance.
