Abstract
A power tool includes a motor, a drive mechanism, and an impact mechanism. The drive mechanism is capable of driving a tip functional element to rotate about an output axis. The impact mechanism is capable of abutting against the tip functional element and capable of driving the tip functional element. The impact mechanism includes an impact rod, an impact power piece, and an impact block. The impact rod abuts against the tip functional element. The impact power piece is used for generating impact power. The impact block is disposed between the impact rod and the impact power piece, capable of forming a gas space with the impact power piece, and capable of reciprocating when impacted by the impact power generated by the impact power piece. A minimum length of the gas space in a direction of the output axis is less than or equal to 13 mm.
