a support mandrel ( 30 ) which projects forward from the finger grip area ( 32 ) of the grip part ( 16 ) and includes the unlocking device ( 28 ) on its underside, with unlocking being effected by supporting the support mandrel ( 30 ) on one of the fingers of the user's hand.
2. The handheld tool ( 10 ) according to claim 1 , wherein the support mandrel ( 30 ) is configured concave on its underside for an at least partially enclosing accommodation of the unlocking finger against the direction of gravity.
3. The handheld tool ( 10 ) according to claim 1 , wherein the actuating device ( 26 ) comprises an electrical actuation pushbutton ( 36 ), which is actuated by an activating force against a restoring force transversely to a grip axis (B) of the grip part ( 16 ) by one of the fingers of the user's hand.
4. The handheld tool ( 10 ) according to claim 1 , wherein the unlocking device ( 28 ) comprises an electrical unlocking pushbutton ( 44 ), which is actuated by a supporting force against gravity along a grip axis (B) of the grip part ( 16 ) by one of the fingers of the user's hand.
5. The handheld tool ( 10 ) according to claim 1 , wherein the actuating device ( 26 ) comprises an actuation contact sensor ( 46 ), which is actuated by a contact of the actuation contact sensor ( 46 ) in a direction transverse to a grip axis (B) of the grip part ( 16 ) by one of the fingers of the user's hand.
6. The handheld tool ( 10 ) according to claim 1 , wherein the unlocking device ( 28 ) comprises an unlocking contact sensor ( 48 ), which is actuated by a contact of the unlocking contact sensor ( 48 ) in a direction along a grip axis (B) of the grip part ( 16 ) by one of the fingers of the user's hand.
7. The handheld tool ( 10 ) according to claim 1 , wherein the unlocking device ( 28 ) comprises a mechanical unlocking mechanism ( 50 ), which mechanically unlocks the actuating device ( 26 ) by a supporting force against gravity along the grip axis (B) of the grip part ( 16 ) by one of the fingers of the user's hand.
8. The handheld tool ( 10 ) according to claim 1 , wherein the actuating device ( 26 ) is provided on the grip part ( 16 ) or the tool body ( 12 ) such that actuation is effected by means of an index finger of the user's hand.
9. The handheld tool ( 10 ) according to claim 1 , wherein the unlocking device ( 28 ) is provided on the grip part ( 16 ) or the tool body ( 12 ) such that unlocking is effected by means of a middle finger of the user's hand.
10. The handheld tool ( 10 ) according to claim 1 , wherein the unlocking device ( 28 ) and the actuating device ( 26 ) are provided symmetrically on the grip part ( 16 ) or the tool body ( 12 ) such that unlocking and actuation can be carried out in the same manner by means of a user's right or left hand.
11. The handheld tool ( 10 ) according to claim 1 , wherein the grip part ( 16 ), on its bottom end facing away from the tool body ( 12 ), can be detachably connected to an electrical battery module ( 24 ) for supplying the handheld tool ( 10 ) with electrical energy.
12. The handheld tool ( 10 ) according to claim 1 , wherein the tool body ( 12 ) includes a hot air fan ( 68 ).
13. An electrical, pistol-like handheld tool ( 10 ), comprising:
a tool body ( 12 ) for electrically activated machining of a workpiece,
a grip part ( 16 ) connected at an angle to the tool body ( 12 ),
an actuating device ( 26 ) for manually activating and/or deactivating the handheld tool ( 10 ), which actuating device ( 26 ) is arranged on the tool body ( 12 ) or the grip part ( 16 ), and
an unlocking device ( 28 ) for manually unlocking and/or locking the actuating device ( 26 ), wherein the unlocking device ( 28 ) is arranged on the tool body ( 12 ) or the grip part ( 16 ) such that unlocking is effected by supporting the handheld tool ( 10 ) in a stable equilibrium on one of the fingers of a user's hand when a user grips the grip part ( 16 ), wherein the unlocking device ( 28 ) comprises a mechanical unlocking mechanism ( 50 ), which mechanically unlocks the actuating device ( 26 ) by a supporting force against gravity along a grip axis (B) of the grip part ( 16 ) by one of the fingers of the user's hand, and wherein the mechanical unlocking mechanism ( 50 ) includes an unlocking rocker ( 56 ), which is held in a locking position by a return spring ( 60 ) connected to its first end ( 58 ), with the second end ( 62 ) of the unlocking rocker ( 58 ) blocking actuation of the actuating device ( 26 ).
14. The handheld tool ( 10 ) according to claim 13 , further comprising:
a support mandrel ( 30 ) which projects forward from the finger grip area ( 32 ) of the grip part ( 16 ) and includes the unlocking device ( 28 ) on its underside, with unlocking being effected by supporting the support mandrel ( 30 ) on one of the fingers of the user's hand.
15. The handheld tool ( 10 ) according to claim 13 , wherein the second end ( 62 ) of the unlocking rocker ( 56 ) is configured U-shaped, and wherein, when unlocking, a pushbutton part ( 38 ) of the actuating device ( 26 ) is centrally guided within the U-shaped end ( 62 ) of the unlocking rocker ( 56 ) and, when locking, the pushbutton part ( 38 ) strikes a locking element ( 54 ) on the U-shaped end ( 62 ) of the unlocking rocker ( 56 ).
