The instrument comprises a guide tube mounted coaxially within the cylindrical body and having an opening which can be aligned any one of the slots, a cover plate provided at the opening of the guide tube and adapted to be tilted by the operation of a knock cap, and a chuck provided to the front end of the guide tube.
