Device for applying temporary fasteners

A tool for installing fasteners, said tool comprising:

• a sheath disposed along a main axis, said sheath containing a cylindrical internal housing with a polygonal base, extending along the main axis,
• a roller cage accommodated within said cylindrical housing, said cage comprising:
• a cylindrical support with a substantially circular base, disposed along the main axis, an external lateral surface of said support being substantially tangent to lateral surfaces of the cylindrical housing with a polygonal base,
• rollers disposed on the perimeter of the support, each roller being able to rotate with respect to said support around an axis parallel to the main axis,
• a compressing spring exerting a radial force on the rollers in the direction of the main axis,
• the cage being configured such that each roller is housed in an edge of the cylindrical housing of the sheath,
• the support of the cage being able to pivot around the main axis within said cylindrical housing,
• the tool being characterized in that it comprises a restoring member, connected to a roller of the cage and to the sheath, said restoring member tending to bring the rollers of the cage to face the edges of the cylindrical housing of the sheath.
