Description

Chain saw Technical Field The utility model relates to the technical field of chain saws, in particular to a chain saw. Background The chain saw is widely used as a common electric tool in the fields of wood cutting, gardening pruning and the like. However, in the working process of the chain saw, a large amount of heat can be generated due to the high-speed operation of the battery pack, the main control board and the motor, if the chain saw is not reasonably guided to be scattered into the atmosphere, the risk of burning can be caused by too high temperature inside the chain saw after long-time working, and the service life and safety of the chain saw are seriously influenced. In addition, when the chain saw cuts wood, the sprocket is prone to accumulate wood chips or other cutting residues, especially at the corner of the upper left corner of the sprocket, where the wood chips are prone to accumulate due to the structural specificity, causing the sprocket to become clogged.
