Hand tool comprising a sensor for emitting a signal when the tool attachment is replaced
First Claim
1. A hand power tool, with a driver mechanism (12), which can operatively connect an inserted tool (16) to a drive shaft (18), characterized in that at least one electrical sensor (10) can detect at least one procedural step in the changing of an inserted tool (16) and can produce a signal, and the signal can prevent an operation of the driver mechanism (12).

Abstract
The invention is based on a hand power tool, in particular a manually operated right angle grinding machine or a manual circular saw, with a driver mechanism (12), which can operatively connect an inserted tool (16) to a drive shaft (18).
The invention proposes that at least one sensor (10) can detect at least one procedural step in the changing of an inserted tool (16) and can produce a signal.

9. A hand power tool, with a driver mechanism (12), which can operatively connect an inserted tool (16) to a drive shaft (18), characterized in that at least one sensor (10) can detect at least one procedural step in the changing of an inserted tool (16) and can produce a signal, the drive shaft (18) can be locked in a piece by means of an actuating button (22) of a locking device (20) in order to change the inserted tool (16) and that the sensor (10) can detect a position of the actuating button (22), the actuating button (22) is operatively connected to the drive shaft (18) in the rotation direction (32, 34) and the actuating button (22) for locking the drive shaft (18) can connect at least one first part (24). which is operatively connected to the drive shaft (18) in the rotation direction, to a second part (26) that cannot rotate in relation to a rotation axis of the drive shaft (18).
