The utility model relates to a driving handle and sliding block mechanism for a grounding switch. The driving handle and sliding block mechanism comprises an operating handle, a crank mechanism, a connecting lever crank mechanism, an energy storage mechanism, a positioning mechanism, a transmission mechanism, a sliding block, a guide rail and a guide rail fixing strip, wherein the crank mechanism comprises an insulating rod, a lower crank head, an upper crank head, a crank shaft and a rotating arm; the connecting lever and crank mechanism comprises a transmission rotating arm, a connecting lever lower crank, a connecting lever upper crank, a connecting lever crank shaft and a connecting lever rotating arm; the transmission mechanism comprises a transmission shaft and a transmission shaft bracket; the operating handle comprises a rotating shaft, a positioning tube, a positioning disk and a positioning pin; and the energy storage mechanism comprises an energy storage spring, an energy storage spring rotating arm and an energy storage spring fixing rod. The driving handle and sliding block mechanism has the advantages of high operation precision, can obtain high and constant switching-on/off driving forces by using a small driving force, increases speed and accuracy degree of switching-on motion, increases contact travel during switching-on and switching-off, and improves reliability and stability of switching-on/off operation as well as operational stability of a solid insulated ring main unit.
