Abstract
A power tool comprises a housing (), a motor () provided inside the housing and for outputting rotary power, and an output shaft () driven by the motor to rotate. The output shaft has an output end connected to a drill bit () and a second end provided on the other end of the output shaft; in a non-working state, the output shaft can axially move relative to the housing along the output shaft; and in a working state, the output shaft is limited in moving in a first axial direction, the first axial direction being an axial direction from the output end to the second end. The drill bit of the power tool can extend in different length according to different positions of the output shaft, so that a working mode is rapidly switched in different working conditions, especially in a small space.
