Abstract
A bit holder includes a body, a spring, a retaining member, and a collar. The body includes a first end and a second end. The body defines a longitudinal bore configured to receive a tool bit and an opening in communication with the longitudinal bore. The spring is disposed on the body. The retaining member is disposed in the opening and is configured to selectively extend into the longitudinal bore to retain the tool bit within the longitudinal bore. The collar is disposed on the body and is biased toward the first end of the body by the spring. The collar is movable in a direction along the body against the spring to secure the tool bit within the longitudinal bore. The collar is movable further in the direction along the body against the spring to enable the bit holder to release the tool bit from the longitudinal bore.
Claims20
A bit holder comprising:
- a body including a first end and a second end, the body defining a longitudinal bore configured to receive a tool bit and an opening in communication with the longitudinal bore;
- a spring disposed on the body;
- a retaining member disposed in the opening and configured to selectively extend into the longitudinal bore to retain the tool bit within the longitudinal bore;
- and
- a collar disposed on the body and biased toward the first end of the body by the spring;
- wherein the collar is movable in a direction along the body against the spring to secure the tool bit within the longitudinal bore, and wherein the collar is movable further in the direction along the body against the spring to enable the bit holder to release the tool bit from the longitudinal bore.
A bit holder comprising:
- a body including a first end and a second end, the body defining a longitudinal bore configured to receive a tool bit and an opening in communication with the longitudinal bore;
- a spring disposed on the body;
- a collar disposed on the body and biased toward the first end of the body by the spring, the collar defining a first cavity and a second cavity that is axially offset and separated from the first cavity, the collar movable along the body;
- and
- a retaining member positioned in the opening, the retaining member being selectively received in the second cavity to enable insertion of the tool bit into the longitudinal bore and being selectively received in the first cavity to enable removal of the tool bit from the longitudinal bore.
A bit holder comprising:
- a body including a first end and a second end, the body defining a longitudinal bore configured to receive a tool bit, a first opening in communication with the longitudinal bore, and a second opening spaced apart from the first opening and in communication with the longitudinal bore;
- a first retaining member received in the first opening, the first retaining member configured to selectively retain the tool bit within the longitudinal bore;
- a second retaining member received in the second opening;
- a spring disposed on the body;
- and
- a collar disposed on the body and biased toward the first end of the body by the spring, the collar being movable relative to the body between a first position, in which the tool bit is insertable into the longitudinal bore, a second position different from the first position, in which the tool bit is secured within the longitudinal bore, and a third position different from the first and second positions, in which the tool bit is removable from the longitudinal bore.
