Abstract

A hand-power tool includes at least one tool spindle and a drive unit configured to drive the at least one tool spindle at a rotational speed greater than 10,000 min−1. The hand-power tool further includes at least one charging energy input and a tool chuck. The at least one charging energy input is arranged on a hand-power tool housing face that faces the tool chuck.

First claim

The invention claimed is:

1. A hand-held power tool, comprising:
a hand-held power tool housing;
at least one tool spindle;
a drive unit configured to drive the at least one tool spindle at a rotational speed higher than 10 000 min −1 ;
at least one charging energy input;
a tool clamping chuck; and
a hose coupling that connects the drive unit to the at least one tool spindle via a friction connection that is configured to slip in response to a block in the driven rotation of the at least one tool spindle,
wherein the at least one charging energy input is arranged on a side of the hand-held power tool housing facing the tool clamping chuck such that, when the at least one charging energy input is engaged with a charger for the hand-held power tool, at least the tool clamping chuck of the hand-held power tool is surrounded by the charger by at least 90 degrees on at least one plane.

2. The hand-held power tool as claimed in claim 1 , wherein the at least one charging energy input has at least one USB interface.

3. The hand-held power tool as claimed in claim 1 , wherein the at least one charging energy input is configured to transmit data.

4. The hand-held power tool as claimed in claim 1 , wherein the drive unit has a maximum power between 15 watts and 150 watts.

5. The hand-held power tool as claimed in claim 1 , further comprising a lithium-based accumulator configured to supply the drive unit with electrical energy.

6. The hand-held power tool as claimed in claim 5 , wherein the accumulator is configured to make available a voltage between 3.4 volts and 15 volts.

7. The hand-held power tool as claimed in claim 1 , wherein the drive unit is connected in a gearless fashion to the at least one tool spindle.

8. A system, comprising:
a hand-held power tool, including: a hand-held power tool housing;
at least one tool spindle;
a drive unit configured to drive the at least one tool spindle at a rotational speed higher than 10 000 min −1 ;
at least one charging energy input;
a tool clamping chuck; and
a hose coupling that connects the drive unit to the at least one tool spindle via a friction connection that is configured to slip in response to a block in the driven rotation of the at least one tool spindle,
wherein the at least one charging energy input is arranged on a side of the hand-held power tool housing facing the tool clamping chuck; and
a charger configured to receive the hand-held power tool and engage with the at least one charging energy input such that, when the charger is engaged with the at least one charging energy input, at least the tool clamping chuck of the hand-held power tool is surrounded by the charger by at least 90 degrees on at least one plane.

9. The system as claimed in claim 8 , wherein the charger is configured to surround the hand-held power tool by at least 90 degrees on at least one plane during a charging process.

10. A hand-held power engraving tool, comprising:
a hand-held power tool housing;
at least one tool spindle;
a drive unit configured to drive the at least one tool spindle at a rotational speed higher than 10 000 min −1 ;
a tool clamping chuck;
at least one charging energy input positioned on a side of the hand-held power tool housing facing the tool clamping chuck; and
a hose coupling that connects the drive unit to the at least one tool spindle via a friction connection that is configured to slip in response to a block in the driven rotation of the at least one tool spindle.

11. The hand-held power tool as claimed in claim 10 , wherein the at least one charging energy input has at least one USB interface.

12. The hand-held power tool as claimed in claim 10 , wherein the at least one charging energy input is configured to transmit data.

13. The hand-held power tool as claimed in claim 10 , wherein the drive unit has a maximum power between 15 watts and 150 watts.

14. The hand-held power tool as claimed in claim 10 , further comprising a lithium-based accumulator configured to supply the drive unit with electrical energy.

15. The hand-held power tool as claimed in claim 14 , wherein the accumulator is configured to make available a voltage between 3.4 volts and 15 volts.

16. The hand-held power tool as claimed in claim 10 , wherein the drive unit is connected in a gearless fashion to the at least one tool spindle.
