Abstract
A depth stop device for a screw driving tool includes an adjusting ring (30), a connection sleeve (22) for rotatably mounting the adjusting ring (30) on the nose member (6) of the screw driving tool housing (4), a substantially sleeve-shaped depth stop (36) displaceable in an axial direction relative the connection sleeve (22) by rotation of the adjusting ring (30), and at least partially elastic locking element (40) engageable in the axial direction with both the adjusting ring (30) and the connection sleeve (22), the locking element being also adapted to secure the adjusting ring (30) on the connection sleeve (22) in a rotational direction (D).
Claims8
A depth stop device (20) for a motor-driven screw driving tool (2) including a housing (4) having a nose member (6) connected with a working tool holder (16) for joint rotation therewith, the depth stop device (20) comprising:
- an adjusting ring (30);
- a connection sleeve (22) for rotatably mounting the adjusting ring (30) on the nose member (6);
- a substantially sleeve-shaped depth stop (36) displaceable in an axial direction relative the connection sleeve (22) by rotation of the adjusting ring (30);
- means (55) for rotationally securing the adjusting ring (30) on the connection sleeve (22) until an adjusting torque in a rotational direction (D) is applied to the adjusting ring (30) by a screw driving tool user;
- and
- means (38) for securing the adjusting ring (30) on the connection sleeve (22) in the axial direction, the securing means (38) including a separate, from the adjusting ring (30) and the
- (40) engageable in the axial direction with both the adjusting ring
- (30) and the connection sleeve (22).
