In one embodiment, each of the positioning holes 11 is disposed coaxially with the receiving hole 12; and the diameter of the positioning hole 11 is smaller than the diameter of the receiving hole 12; in another embodiment, The diameter of the positioning hole 11 is smaller than the diameter of the spherical body 2, and the diameter of the receiving hole 12 is longer than the diameter of the spherical body 2. For example, the spherical body 2 is a golf ball, and generally The length of the hole is 42.8 mm (Millimeter), and the diameter of the positioning hole 11 of the present invention is 41.7 mm (Millimeter), and the diameter of the receiving hole 12 is 42.8 mm (Millimeter); and the body 1 corresponds to the receiving hole 12 The at least one through hole 13 is disposed, and the positioning hole 11, the receiving hole 12 and the through hole 13 are connected to the accommodating space;

a cover body 3, which is correspondingly arranged with the body 1, and the cover body 3 corresponding to the positioning hole 11 is respectively provided with a mark hole 31;

a tank body 4 having the body 1 accommodated therein; and when the tank body 4 is in a first state, the interior thereof is filled with liquid.
