Abstract
A chain saw has a housing, a guiding plate, a chain, a power system and a tensioning component. The tensioning component includes a knob, a driving member and a transmission assembly. When the chain is in a loose state, the knob is forced to rotate and drives the transmission assembly to rotate, and the transmission assembly drives the driving member to rotate, then the driving member drives the guiding plate to move to tension the chain. When the chain is in an extension state, the knob is forced to rotate, the driving member stays still, and a skidding inside the tensioning component is generated. The tensioning component of the chain saw of the present invention can tension the chain and fix the guiding plate by rotating the knob, the operation is simple and convenient; Meanwhile, the tensioning component avoids over-tensioning the chain by skidding inside.
