Abstract:
1. A tool device comprising: a tool shank including an engaging hole formed in one end of said tool shank, and said engaging hole including a noncircular cross section, said tool shank including an orifice formed therein, a socket member slidably engaged into said engaging hole of said tool shank and including a noncircular outer peripheral portion for engaging with said noncircular engaging hole of said tool shank and for allowing said socket member to be rotated or driven by said tool shank, said socket member including a bore formed therein and having a noncircular cross section, said socket member including at least one recess formed in an outer peripheral portion thereof and including at least one stop extended into said at least one recess of said socket member and located at one end portion of said at least one recess of said socket member, means for biasing said socket member outwardly relative to said engaging hole of said tool shank, and said biasing means including a spring member engaged into said engaging hole of said tool shank for applying a spring biasing force against said socket member, means for detachably and slidably anchoring said socket member to said tool shank, said anchoring means including a detent slidably received and engaged into said orifice of said tool shank and extendible into said engaging hole of said tool shank for selectively engaging with said at least one recess of said socket member and for selectively engaging with said at least one stop of said socket member and for detachably anchoring said socket member to said tool shank, and said anchoring means including a control ferrule slidably engaged onto said tool shank and selectively engageable with said detent and for selectively forcing said detent to engage with said socket member, and said control ferrule including a peripheral depression formed in an inner peripheral portion thereof for selectively receiving said detent and for forming an actuator which is selectively engageable with said detent to selectively force said detent to engage with said socket member.
