Direct-current high branch pruning saw

The utility model discloses a direct-current high branch pruning saw comprising a handle, a connecting rod, a casing, a motor, a transmission mechanism, a chain wheel and a chain. The handle is connected with the casing by the connecting rod; the motor is arranged inside the casing; and the motor drives the chain wheel to make rotations by the transmission mechanism. According to the utility model, due to the utilization of the above-mentioned technical scheme, a direct-current power source is used to supply power and the saw can be carried conveniently, so that the work range of the saw is widened and the work efficiency is effectively improved; moreover, the performance of recycling with multiple times of the battery enables the saw to achieve an objective of energy conservation and environment protection. In addition, a direct current motor type transmission structure is employed and thus the appearance of the head of the saw is slender, so that a problem of inconvenient advancing and retreating movements
