Abstract:
1. A tool bit holder, comprising: a shaft having a front end, a rear end, a sidewall defining a bit receiving cavity extending from the front end toward the rear end, and an opening extending through the sidewall and communicating with the bit receiving cavity; a bit retention device received in the opening; a first spring substantially surrounding the shaft and projecting at least partially into the opening to bias the bit retention device toward the front end of the shaft, the inward projecting portion having at least a partially curvilinear shape that is complementary to a shape of the bit retention device; and an actuator sleeve substantially surrounding the shaft and having an internal wall that engages the bit retention member, wherein the actuator sleeve is moveable between a rearward position in which the internal wall pushes the bit retention member radially inward toward the cavity to engage a tool bit that is received in the cavity, and a frontward position in which the internal wall allows the bit retention member to move radially outward from the cavity to disengage from a tool bit that is received in the cavity.
