  • Patent number: 12768611
    Abstract: A water gun is provided. On the water gun, when a first mating position and a second mating position are in alignment fit, a plug-in member is detachably plugged into a plug-in hole, so that a reset clamping member is movably clamped to the plug-in member, thus achieving quick assembling and disassembling of a storage device and a gun body, and enhancing disassembling convenience. Furthermore, when the first mating position and the second mating position are in alignment fit, a first conductive component and a second conductive component are also in detachable fit, so that an electrical element or a power source on the storage device can be mated and electrically connected with a circuit on the gun body, thus eliminating an additional circuit mating and assembling step and further simplifying an assembling process.
