摘要： The invention relates to a chuck having a sleeve, a chuck body, a plurality of chuck jaws, an adjusting mechanism configured to adjust relative movement between the chuck jaws and the chuck body, at least one locating member and a pushing mechanism. The locating member is disposed on the chuck body between the adjacent chuck jaws. When the adjusting mechanism drives the chuck jaws to approach to each other relative to the longitudinal axis, the pushing mechanism pushes the locating member to move towards the longitudinal axis. When the adjusting mechanism drives the chuck jaws to move away from each other relative to the longitudinal axis, the pushing mechanism pushes the locating member to move away from the longitudinal axis. Therefore, the operation is more convenient and safer; the aligning effect is precise and reliable, and the pre-tightening force is stable.

摘要： A power tool comprises a housing (1), a motor (2) provided inside the housing and for outputting rotary power, and an output shaft (4) driven by the motor to rotate. The output shaft has an output end connected to a drill bit (9) 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.
