Hand-held power tool

1. A hand-held power tool comprising:

a tool socket;

a motor; and

a pneumatic striking mechanism having an exciter driven by the motor along a working axis, a striker coupled to the exciter via an air cushion, an intermediate striker arranged between the striker and the tool socket in the striking direction, and a guide in which the intermediate striker is guided, the guide having a first sliding surface guiding a first section of the intermediate striker and a second sliding surface arranged offset relative to the first sliding surface in the striking direction and guiding a second section of the intermediate striker, a radial dimension of the first section of the intermediate striker being greater than a radial dimension of the second section of the intermediate striker;

the intermediate striker having a front section in a direction of the striker, the front section being unguided when the intermediate striker is in contact with a stop in the striking direction; wherein all further sections of the intermediate striker arranged before the first section in the striking direction are not guided, at least when the intermediate striker is in contact with the stop in the striking direction.

2. The hand-held power tool as recited in claim 1 wherein in every position in the guide, the intermediate striker is in contact with the first sliding surface and with the second sliding surface.

3. The hand-held power tool as recited in claim 1 wherein a length of the second sliding surface is less than 25% of a section length of the second section.

4. The hand-held power as recited in claim 1 wherein the first sliding surface is parallel to the working axis or else at a distance from the working axis at an angle of less than 5° in the striking direction.

5. The hand-held power tool as recited in claim 1 wherein the first sliding surface and the second sliding surface are inner surfaces of a one-part sleeve.

6. The hand-held power tool as recited in claim 1 wherein at least one of the first sliding section and the first section have grooves running along the working axis.

7. The hand-held power tool as recited in claim 1 further comprising a sealing ring arranged on the second sliding surface.

8. The hand-held power tool as recited in claim 1 wherein the front section is a third section, the radial dimension of the first section being greater than a radial dimension of the third section.

9. The hand-held power tool as recited in claim 8 wherein the second section and the third section have a same diameter.

10. The hand-held power tool as recited in claim 9 wherein a first diagonal facet runs between the second section and the first section, and a second diagonal facet runs between the third section and the first section.

11. The hand-held power tool as recited in claim 10 wherein the first facet forms a counterpart for the stop.

12. The hand-held power tool as recited in claim 10 wherein the first facet forms a counterpart for a second stop in a direction opposite the striking direction.

13. The hand-held poser tool as recited in claim 1 wherein the intermediate striker is a solid body between an outer surface.

14. The hand-held power tool as recited in claim 1 wherein an entirety of the striker is in front of the intermediate striker.

15. A hand-held power tool comprising:

a tool socket;

a motor; and

a pneumatic striking mechanism having an exciter driven by the motor along a working axis, a striker coupled to the exciter via an air cushion, an intermediate striker arranged between the striker and the tool socket in the striking direction, and a guide in which the intermediate striker is guided, the guide having a first sliding surface guiding a first section of the intermediate striker and a second sliding surface arranged offset relative to the first sliding surface in the striking direction and guiding a second section of the intermediate striker, a radial dimension of the first section of the intermediate striker being greater than a radial dimension of the second section of the intermediate striker;

the intermediate striker having a front section in a direction of the striker, the front section being unguided when the intermediate striker is in contact with a stop in the striking direction

wherein the intermediate striker is a solid body between an outer surface.

16. A hand-held power tool comprising:

a tool socket;

a motor; and

a pneumatic striking mechanism having an exciter driven by the motor along a working axis, a striker coupled to the exciter via an air cushion, an intermediate striker arranged between the striker and the tool socket in the striking direction, and a guide in which the intermediate striker is guided, the guide having a first sliding surface guiding a first section of the intermediate striker and a second sliding surface arranged offset relative to the first sliding surface in the striking direction and guiding a second section of the intermediate striker, a radial dimension of the first section of the intermediate striker being greater than a radial dimension of the second section of the intermediate striker;

the intermediate striker having a front section in a direction of the striker, the front section being unguided when the intermediate striker is in contact with a stop in the striking direction

wherein the front section is a third section, the radial dimension of the first section being greater than a radial dimension of the third section and wherein the second section and the third section have a same diameter.

17. The hand-held power tool as recited in claim 16 wherein a first diagonal facet runs between the second section and the first section, and a second diagonal facet runs between the third section and the first section.

18. The hand-held power tool as recited in claim 17 wherein the first facet forms a counterpart for the stop.

19. The hand-held power tool as recited in claim 17 wherein the first facet forms a counterpart for a second stop in a direction opposite the striking direction.
