  • Patent number: 10376973
    Abstract: A chainsaw includes a housing, a prime mover, a transmitting member and a bias assembly. The prime mover is mounted to the housing. The saw chain is driven by the prime mover. The guide bar guides the saw chain and the guide bar is slidably connected to the housing. The driving member drives the guide bar to slide relative to the housing. The operating member swings forth and back relative to the housing. The transmitting member enables the driving member to rotate synchronously with the operating member when the operating member is swung forth and enables the operating member to rotate relative to the driving member when the operating member is swung back. The bias assembly biases the transmitting member to engage with the operating member when the operating member is swung forth.
