Description

Technical Field

[0001] The utility model relates to the field of wood cutting auxiliary equipment, in particular to an auxiliary cutting component of an oil saw. Background Art

[0002] A chainsaw, also known as a chain saw, is a portable sawing tool commonly used in forestry logging, garden pruning, construction and disaster relief. It mainly consists of an engine, a saw chain, a guide bar, a handle and a guard. A chainsaw can be used for a variety of different cutting tasks, such as logging, pruning, shaping, etc. For occasions that require precise cutting, such as woodworking or architectural joinery, auxiliary cutting components can help the chainsaw maintain a straight cut and improve cutting accuracy.

[0003] The application of traditional chain saw auxiliary cutting components in forestry has had a significant impact on forestry work. Traditional chain saw auxiliary cutting components usually include an internal combustion engine, a saw chain and a sprocket. The internal combustion engine generates power by burning gasoline or diesel, and then drives the sprocket to rotate. The saw chain cuts trees or wood through the rotation of the sprocket. The internal combustion engine starts, burns fuel to generate power, and the power is transmitted to the sprocket through the transmission device. The sprocket rotates and drives the saw chain to cut trees or wood. After the cutting is completed, the internal combustion engine is turned off. In forestry, the use of chain saws has greatly improved the efficiency of wood felling and processing.

[0004] The above-mentioned traditional chainsaw auxiliary cutting components also have some problems. The design and use of chainsaws also have a certain impact on the forestry environment. Traditional chainsaws use gasoline or diesel as fuel. The exhaust gas produced by combustion contains harmful substances, which pollutes the air quality. The chainsaw is large in size and is not very convenient to carry and transport, especially in complex terrain and for long-term operations. Utility Model Content
