Abstract
The tools are hand drills for a home worker combination machine. The device has a break contact in the tool connection, which opens when a temp. threshold is exceeded. A driving element (2) always presses on the break contact (1) in its opening direction, And a blocking element (3) blocks its opening in its first position, and permits it in its second position. The blocking element (3) is coupled with a temp. sensitive control element (4), so that when the temp. threshold is exceeded, the control element (4) moves the blocking element (3) from its first to its second position.
