Abstract
A power tool and a detection method for the power tool. The detection method includes collecting acceleration data, via use of an acceleration sensor of the power tool, along a tangential direction of a rotation axis of a working portion of the power tool, determining whether a proportion of the collected acceleration data that exceeds a first acceleration threshold in a preset time window exceeds a preset value, and determining that a kickback occurs in the power tool when the proportion exceeds the preset value.
