Patent ID: 7604184

Claim:
A rotatable water-spraying bat, comprising: (a) a water storage cylinder including a cylinder body with an external surface covered by a hollow mount made from a soft material, wherein a front end of the water storage cylinder includes a spraying hole, and at an opening area of a rear end of the water storage cylinder, two fastening plates are protrudingly mounted, wherein a front end of an inner ring of each fastening plate includes a recess, and a front end of each recess includes a guiding corner; and (b) a hollow pushing-piston having a front end and a rear end, the front end having mounted thereon, a soft plug for inserting through the opening area of the water storage cylinder into an internal diameter of the water storage cylinder, and the rear end including a holding section with two L-shaped fastening plates, wherein the two L-shaped fastening plates permit connection of the holding section to the fastening plates of the water storage cylinder when the pushing-piston is fully inserted into the water storage cylinder, and wherein an external diameter of the pushing piston at an inner end of the L-shaped fastening plates includes two protruded rings, whereby each recess of the two fastening plates permit insertion of the corresponding L-shaped fastening plates therein, such that rotation therebetween urges each protruded ring into fastening engagement with a corresponding recess, and such that dislocation of the pushing-piston from the water storage cylinder is prevented in the event of a great impact onto the spray bat.
