Abstract
A tool bit holding device comprises an inner tube, an outer tube, and a clip. The inner tube includes an end and a compartment proximate the end. The inner tube includes an annular groove defined in an outer periphery thereof. A bottom wall defining the annular groove includes at least one slot to thereby communicate the annular groove with the compartment. The outer tube is mounted around the inner tube and slidable along a longitudinal direction of the inner tube. The clip is mounted in the annular groove of the inner tube, The clip includes at least one rectilinear section that is received in the slot and thus partially received in the compartment.
Claims19
A tool bit holding device comprising:
- an inner tube including an end and having an inner periphery, an outer periphery, and a compartment, with the compartment being proximate the end and defined by the inner periphery of the inner tube, with the inner tube including an annular groove defined in the outer periphery thereof, with the annular groove having a bottom wall located intermediate the inner periphery and the outer periphery, with the bottom wall defining the annular groove and including at least one slot extending from the annular groove to the inner periphery to thereby communicate the annular groove with the compartment;
- an outer tube mounted around the inner tube and slidable along a longitudinal direction of the inner tube;
- and
- a clip mounted in the annular groove of the inner tube, the clip including at least one section that is received in said at least one slot and thus partially received in the compartment.
A tool bit holding device comprising:
- an inner tube including an end and having a compartment, the end of the inner tube including an annular groove defined in the outer periphery thereof, a bottom wall defining the annular groove including at least one slot to thereby communicate the annular groove with the compartment, wherein said at least one slot is rectilinear;
- an outer tube mounted around the inner tube and slidable along a longitudinal direction of the inner tube;
- and
- a clip mounted in the annular groove of the inner tube, the clip including at least one rectilinear section that is received in said at least one slot and thus partially received in the compartment.
A combination of a tool bit and a tool bit holding device, the combination comprising:
- an inner tube including an end and having an inner periphery, an outer periphery;
- and a compartment, with the compartment being proximate the end and defined by the inner periphery of the inner tube, with the inner tube including an annular groove defined in the outer periphery thereof, with the annular groove having a bottom wall located intermediate the inner periphery and the outer periphery, with the bottom wall defining the annular groove and including at least one slot extending from the annular groove to the inner periphery to thereby communicate the annular groove with the compartment;
- an outer tube mounted around the inner tube and slidable along a longitudinal direction of the inner tube;
- a clip mounted in the annular groove of the inner tube, the clip including at least one section tat is received in said at least one slot and thus partially received in the compartment;
- and
- a tool bit having an end releasably received in the compartment of the inner tube;
- said at least one section of the clip in contact with and exerting a radially inward force to the end of the tool bit through the slot of the annular groove, thereby securely retaining the tool bit in place.
