Patent ID: 7104168

Claim:
A slide stop device of a hexagonal spanner for preventing a rounded edged inner hexagonal screw to slide as the hexagonal spanner drives the inner hexagonal screw; the slide stop device comprising: a spanner body; one end of the spanner body having a driving portion; the driving portion having: at least one axial slot; each slot being extended from a center of one end surface of the driving portion to apexes or lateral sides of a hexagonal cross section of the driving portion; a screw hole formed along an axial direction of driving portion; an outer end of the screw hole in the axial center of the driving portion having a tapered shape; a through hole extending from an inner side of the screw hole and being at the same line with the screw hole; the through hole penetrating through a wall of the driving portion; a screwing resisting element having a shape matching the shape of the screw hole; a head end of the screwing resisting element having a tapered shape; the screwing resisting element being capable of being screwed into the screw hole; another end of the screwing resisting element having a driving hole; and wherein another end of the spanner body having a driving end; the driving portion having at least one second axial slot; each second slot being extended from a center of one end surface of the driving end to apexes or lateral sides of a hexagonal cross section of the driving end; a second screw hole formed along an axial direction of driving end; an outer end of the second screw hole in the axial center of the driving end having a tapered shape; a second through hole extending from an inner side of the second screw hole and being at the same line with the second screw hole; the second through hole penetrating through a wall of the second driving portion; a second screwing resisting element having a shape matching the shape of the second screw hole; a head of the second screwing resisting element having a tapered shape; the second screwing resisting element being capable of being screwed into the second screw hole; one end of the second screwing resisting element having a second driving hole so that an opening can be inserted into the cruciform hole to drive the second screwing resisting element to rotate.
