Tool device for driving various tool members

摘要

A tool device includes a tool shank having a noncircular engaging hole for slidably receiving a socket member which includes a noncircular bore for engaging with various fasteners, a biasing device may bias the socket member outwardly relative to the engaging hole of the tool shank, and an anchoring device may slidably anchor the socket member to the tool shank. One or more socket members may be replaced with each other and may be selectively engaged into the engaging hole of the tool shank, for receiving and driving various tool members of different sizes or diameters or dimensions.
