Anti-expansion and anti-leakage carbon battery

The utility model discloses an anti-expansion and anti-leakage carbon battery, which belongs to the technical field of batteries and comprises a zinc cylinder, a protective net is sleeved on the surface of the zinc cylinder, a buffer component is mounted on the outer side of the protective net, and a partition component is sleeved on the surface of the buffer component. The interval grooves are used for providing buffering intervals to prevent the buffering cylinders from making direct contact with the protective net, the buffering supporting pieces are stressed to deform, the external impact force can be well weakened and counteracted, the influence and interference on the batteries are reduced to the minimum, and therefore the protection effect on the batteries is better. According to the utility model, the separation assembly is arranged, the separation sleeve is rotated to drive the lantern ring on the surface of the telescopic cylinder to rotate, the telescopic cylinder can be moved out under the threade
