    摘要: The quick-release chuck for a rotary power tool is provided for holding a tool bit. The chuck includes a barrel having an axial bore to receive the tool bit and an axially movable sleeve operable to position a locking member to selectively lock or release the tool bit. A proximal end of the chuck near the housing of the power tool includes a low-profile collar which holds a spring in compression against the sleeve, biasing the sleeve in a distal, locked position. The components of the chuck may advantageously be assembled in a stacked manner. The low-profile collar permits the chuck to occupy a minimal length and to be positioned with a minimal separation from the housing of the power tool for enhanced safety.
