Power supply with protective structure for naval vessel communication

The utility model belongs to the technical field of naval vessel communication power supplies, in particular to a naval vessel communication power supply with a protective structure, which comprises a protective shell, an elastic rod and a rotary button, the elastic rod is movably connected with a rotating wheel, a second compression spring is arranged on one side of the elastic rod, first sliding blocks are arranged at two ends of the elastic rod, and a second compression spring is arranged on the other side of the elastic rod. The first sliding block is movably connected with the third sliding groove. Through the arrangement of the elastic rod, the second compression spring, the first sliding block and the sliding groove, when the protection shell is impacted, the first sliding block can move in the sliding groove, meanwhile, the second compression spring contracts under the pressure of the elastic rod to achieve the damping effect, the borne impact force is buffered, and the power source is prevented from
