Abstract:
A socket spanner with a retaining device comprising a socket and an elastic body;wherein said socket has a driven end with a hexagonal hole having six inner side faces;said elastic body comprising a press portion and a longitudinally extending retaining leg which extends from said press portion, said retaining leg being made of a thin strip having a width substantially greater than its thickness;said press portion comprising a full-ring with a diameter slightly greater than a distance between two opposing faces of said hexagonal hole so as to allow said elastic body to be received and retained in said hexagonal hole;said retaining leg comprising a bent portion, a first straight portion, a second straight portion, and a radially inwardly protruding portion, with said bent portion connecting said retaining leg with said press portion;further wherein said retaining leg is structured to allow a nut to be received in said hexagonal hole, said first and second straight portions being generally parallel to an inner face of said hexagonal hole, and that said radially inwardly protruding portion, which is disposed between said first and second straight portions, is constructed to be pressed against an inner side face of said hexagonal hole by the nut so that said radially inwardly protruding portion exerts an urging force against the nut to retain the nut when the nut is inserted into said hexagonal hole.
