- These means 23 may in particular comprise at least one choice ring 24 at the front of the handle.
- a pin 25 integral with the choice ring 24 can cooperate with a groove 26 of said tool-holder rod, parallel to the longitudinal axis of said tool-holding rod 3.
- the rotation of the ring of choice causes the rotation of the pin 25, to position the free end of the pin 25, or in the groove 26 to allow the translation of said rod for tool holder relative to the body 2, and thus the use of the tool in percussion mode, or on the contrary take out the pin 25 of the groove 26 in a position in which the pin 25 blocks the translation of the tool-holder shaft 3.
- the ring of choice has, an indexing system, in our example, a ball 41 pressed by a spring, adapted to cooperate in two angular positions with two depressions of the body 2 to allow the indexing of its two operating positions of the tool, namely percussion operation or operation screwing / unscrewing.
- an indexing system in our example, a ball 41 pressed by a spring, adapted to cooperate in two angular positions with two depressions of the body 2 to allow the indexing of its two operating positions of the tool, namely percussion operation or operation screwing / unscrewing.
