[0002] A lithium-ion chain saw is an electric tool powered by a lithium battery. It is mainly composed of a motor, a saw blade, and a chain. The lithium-ion chain saw uses a chain for movement, and different saw blades and chains can be replaced according to different work needs. Lithium-ion chain saws are suitable for outdoor work such as logging and felling trees. Because of the characteristics of lithium-ion battery supply, lithium-ion chain saws can be made smaller and lighter than oil saws, which is convenient for use in more scenarios. However, when using a lithium-ion chain saw for a long time, the vibration and weight will cause wrist fatigue. The lithium battery generally installed at the tail of the lithium-ion chain saw accounts for nearly half of the weight of the lithium-ion chain saw, making the chain saw bulky to use and more likely to make the user feel tired.

[0003] After searching, the Chinese patent publication number CN209435859U discloses a lightweight lithium-electric chain saw, including a storage box, a brake motor and a stepper motor. A first handle is fixed at the end of the storage box, and a switch is installed inside the first handle. At the same time, a second handle is fixed on the upper surface of the storage box, a battery pack is installed inside the storage box, and a brake motor is arranged inside the storage box, a saw chain is arranged on the outside of the first gear, and a support plate is installed inside the saw chain, and a connecting rod is installed in the middle position of the support plate.

[0004] In view of the problem that the battery pack in the device in the above-mentioned technology requires a certain weight, and if a longer battery life is required, a larger battery needs to be used, but this will seriously affect the user experience of the chainsaw and is inconvenient to replace; therefore, a lightweight lithium-electric chainsaw is proposed.
