Abstract
A screw driving tool including an axially displaceable, drive spindle (5) located in the housing, a bit holder (6) having a shank (7) which releasably connects the bit holder (6) with the drive spindle (5), an axially adjustable depth stop (9) surrounding the bit holder (6) and a portion of the drive spindle (5) and connectable with the tool housing (1), and a sleeve-shaped dust-repelling member (13) arranged between the depth stop (9) and the bit holder (6) and releasably connected with the bit holder (6).
Claims8
A screw driving tool, comprising a housing (1) having a neck section (4);
- an axially displaceable, drive spindle (5) located in the housing;
- a bit holder (6) having a shank (7) for releasably connecting the bit holder (6) with the drive spindle (5);
- an axially adjustable depth stop (9) surrounding the bit holder (6) and a portion of the drive spindle (5) and connectable with the housing (1);
- and a sleeve-shaped dust-repelling member (13) arranged between the depth stop (9) and the bit holder (6) and releasably connected with the bit holder (6),
- wherein the dust repelling member has at least one circumferential profile means (15) provided on an outer surface (14) of the dust-repelling member (13) and formed as a left-hand trapezoidal thread.
A screw driving tool, comprising a housing (1) having a neck section (4);
- an axially displaceable, drive spindle (5) located in the housing;
- a bit holder (6) having a shank (7) for releasably connecting the bit holder (6) with the drive spindle (5);
- an axially adjustable depth stop (9) surrounding the bit holder (6) and a portion of the drive spindle (5) and connectable with the housing (1);
- a sleeve-shaped dust-repelling member (13) arranged between the depth stop (9) and the bit holder (6) and releasably connected with the bit holder (6);
- and a sleeve-shaped connection member (19) for connecting the depth stop (9) with the housing (1),
- wherein the sleeve-shaped connection member (19) has a bore (20) extending transverse to a screw-in direction and into which a side opening (12) which is formed in the depth stop (9), opens.
