Setting tool

Abstract

A hand-held setting tool for driving fastening elements in a workpiece includes a muzzle member (20) axially displaceable relative to the tool housing (11) in a direction of an operational axis (A) of the setting tool (10), a feeding channel (28) for a fastening element strip (50) and arranged in the muzzle member (20) and opening into a fastening element the receiving chamber (29) provided in the muzzle member (20), and a locking member (40) arranged on the muzzle member (20) and forming a locking section (42) displaceable into the feeding channel (28), and a blocking section (41) for preventing displacement of the muzzle member relative to the housing.

Claims

1. A hand-held setting tool for driving fastening elements in, comprising a housing (11); a muzzle member (20) axially displaceable relative to the housing (11) in a direction of an operational axis (A) of the setting tool (10) and having a chamber (29) for receiving a fastening element (51); a feeding channel (28) for a fastening element strip (50) and arranged in the muzzle member (20) and opening into the receiving chamber (29); and a locking member (40) arranged on the muzzle member (20) and forming a locking section (42) displaceable into the feeding channel (28), and a blocking section (41) for preventing displacement of the muzzle member (20) relative to the housing (11).

2. A setting tool according to claim 1, further comprising a press-on feeler (30) axially displaceable in a guide space (31) provided in the muzzle member (20); a spring (32) for resiliently biasing the press-on feeler (30) in a direction of a release position thereof out of the guide space (31), and wherein the blocking section (41) of the locking member (40) is lockingly displaceable in the guide space (31) for the press-on feeler (30).

3. A setting tool according to claim 2, wherein the press-on feeler (30) has a locking profile (34) that provides for locking of the locking member (40).

4. A setting tool according to claim 1, wherein the blocking section (41) is formed on a side of the locking member (40) remote from the feeding channel (28).

5. A setting tool according to claim 1, further comprising spring means (47) for elastically biasing the locking member (40) in a direction of an engagement position of the locking section (42) in the guide channel (28).

6. A setting tool according to claim 1, further comprising a fastening element magazine (53) projecting from the muzzle member (20) and from which the fastening element strip (50) is fed into the feeding channel (28), wherein the fastening element magazine (53) has an elastically biased, displaceable transportation slide (54) having an adjusting profile (55) that is brought in abutment with a counter-profile (45) on the locking member (40) for displacing the locking member (40) in a position in which the locking member (40) prevents the displacement of the muzzle member (20) relative to the housing (11) when no fastening element strip (50) is located in the feeding channel (28).

7. A setting tool according to claim 1, wherein a support profile (27) for the fastening element, strip (50) that projects into the feeding channel (28) is provided on a side of the feeding channel (28) opposite the locking section (42) of the locking member (40).

8. A setting tool according to claim 1, wherein the locking member (40) is formed as a pivotal lever.
