IMPROVEMENTS IN OR RELATING TO SPANNERS

摘要

A spanner which enables simple and rapid removal of a loosened nut. The spanner (1) has a manually-operable handle (12) squeezing of which causes reciprocation of shaft (6) and bifurcated member (5). Assymetrical teeth (19) on the bifurcated member engage and rotate member (4). The member (4) forms part of the mechanism of a ratchet-spanner and a socket is usually attached thereto for removing nuts from bolts. Once the nut has been loosened in conventional manner, pumping of handle (12) causes rapid rotation of the socket and speedy removal of the nut.
