ABSTRACT:
A chisel quickly adjusting and positioning device for a chiseling machine includes a plurality of separating members for adjusting a gap between a sleeve and the bottom of a machine body, and a chisel unit composed of a chisel and a drill fitting lengthwise in the chisel. After the drill is fitted in the chisel and then clamped in a drill chuck, the chisel unit is fitted in the sleeve. Then the separating members can be pivotally moved in or out of the gap between the sleeve and the bottom of the machine body, and then the sleeve is pushed up so that a gap between the chisel blade and the tip of the drill may be formed for quickly adjusting and positioning the chisel unit with the machine body.
