| 摘要 |
The invention concerns a device for protecting a cutting and/or drilling tool (A), comprising: means (4) for isolating from outside a cutting and/or drilling distal part (12) of the tool, said means being connected to a non-cutting and/or non-drilling part of the tool with limited relative mobility and having an opening for said distal part to move between a protected position, wherein the means for isolating the tool encloses at least partially said distal part, and a working position, wherein said distal part is released from the means isolating the tool; elastic means (13) for returning the distal part in the protected position, said distal part being capable of moving towards its working position by the effect of an external pressure (F) countering the elastic return force.
