Abstract
A bit retention device has an upper support member having an inner surface and an outer surface. A lower support member fixed to the upper support member. A stationary plate is mounted to the inner surface of the upper support member. A clamp plate opposes the stationary plate and is spring biased toward the stationary plate and slidably moveable between the upper support member and the lower support member.

An anchor setting tool comprising:
- a housing having a handle portion, a transmission portion and a forward portion;
- a bit retention device disposed at least partially within the forward portion for retaining a tool bit in a longitudinal direction, the bit retention device including:
- a stationary plate;
- and
- a clamp plate biased toward the stationary plate,
- a motor;
- a transmission mechanism arranged in the transmission portion and driven by the motor;
- a striking rod disposed in the forward portion between the transmission mechanism and the bit retention device, the striking rod being moveable in a reciprocating manner from an impact received from the transmission mechanism to strike the tool bit;
- and
- a power source to power the motor.
A method for retaining a bit in a bit retention device having a longitudinally extending upper support member and a longitudinally extending lower support member encasing a clamp plate spring assembly, comprising:
- providing a stationary plate mounted to the lower support member,
- providing a spring-biased clamp plate opposing the stationary plate and slidably moveable between the upper support member and the lower support member, and biased toward the stationary plate;
- and
- inserting a tool bit between the stationary plate and the clamp plate to move the clamp plate away from the stationary plate.
