Publication number: 20150202751Abstract: A tool bit adapter includes a base member including a cylindrical body having a receiving open chamber formed of a front small diameter portion, a rear large diameter portion and one or multiple through holes in communication between the small diameter portion and the atmosphere, a ball mounted in each through hole, an operating member slidably sleeved onto the cylindrical body and having an inside groove and a pressure face, a pusher accommodated in the cylindrical body and having one or multiple recessed retaining portions. When the pusher is in the rear end position, the pressure face of the operating member forces the balls toward the inside of the receiving open chamber into engagement with the respective recessed retaining portions. Thus, the tool bit adapter can positively detachably secure the loaded tool bit without any additional positioning structure.Type: ApplicationFiled: April 18, 2014Publication date: July 23, 2015Applicant: GOOD YEAR HARDWARE CO., LTD.Inventor: Tsai-Ching CHEN

Patent number: 8342062Abstract: A multi-angle hand tool for a handle includes a shank including a body, and a compartment defined in the body. An operating device includes a connecting end having an engaging portion defined thereon. A guide is mounted in the compartment and includes an embedding portion defined thereon. A connecting device is disposed and interconnected between the operating device and the guide. The multi-angle hand tool has a plurality of operation modes, and, in each operation mode, the operating device is prevented from moving and pivoting with respect to the shank by engaging the engaging portion with the embedding portion. Furthermore, a longitudinal length of the operating device is perpendicular to, angled non-perpendicularly to, or aligned with the longitudinal length of the body of the shank selectively for different operation modes.Type: GrantFiled: September 17, 2010Date of Patent: January 1, 2013Inventors: Tsai-Ching Chen, Fanny Hi
