Abstract:
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.

Claim (Index 4):
The chuck according to  claim 3 , wherein when the sleeve rotates along a first direction relative to the chuck body, the locating member extends into the first shaft cavity close to the longitudinal axis through the second guide hole to hold the tool bit, and the chuck jaws extend into the first shaft cavity through the first guide holes and approach to each other relative to the longitudinal axis so as to clamp the tool bit received in the first shaft cavity of the chuck body, when the sleeve rotates in a second direction opposite to the first direction relative to the chuck body, the locating member moves away from the longitudinal axis, and the chuck jaws are apart from the longitudinal axis to release the tool bit received in the first shaft cavity of the chuck body.
