ABSTRACT:
A tool coupler is provided, comprising an elongated body having upper and lower ends and further including a non-circular first axial bore extending at least partially through the body from the upper end toward the lower end, a flange extending radially from the body, and at least one radial bore communicating between the first axial bore and the exterior of the body, the radial bore being located just above the flange. A collar is positioned around the body, the collar having upper and lower ends, an inner wall and an outer wall, and an annular retaining flange extending radially from the inner wall, the retaining flange being alignable with the radial bore. A cap is positioned in the collar, the cap having an upper surface, an annular outer surface facing the inner surface of the collar, an annular lower surface, the cap further including an axial opening at least as large as and aligned with the first axial bore in the body. A first spring is positioned between the cap and the annular flange of the collar, urging the cap against the upper end of the collar. At least one ball is positioned in the radial bore, the ball having a greater length than the radial bore such that when the retaining flange of the collar is aligned with the radial bore, the ball is urged at least partially into the first axial bore to grip a tool shank.
