The invention discloses a transverse holding fork auxiliary linkage single-handle operation device for a loader. The transverse holding fork auxiliary linkage single-handle operation device comprises a holding fork body, fork bodies, holding fork oil cylinders, a hydraulic control assembly and a function switching switch. The fork bodies are movably installed on the holding fork body and driven by the holding fork oil cylinders to move transversely along the two sides of the holding fork body. The fork bodies comprise the left fork body and the right fork body. The holding fork oil cylinders comprise the left holding fork oil cylinder and the right holding fork oil cylinder. The left holding fork oil cylinder and the right holding fork oil cylinder drive the left fork body and the right fork body to move respectively. The hydraulic control assembly comprises reversing valves controlled by a loader operation handle and electromagnetic valves controlled by the function switching switch. The switch of the series connection and the parallel connection of the left holding fork oil cylinder and the right holding fork oil cylinder is achieved through the switch of the electromagnetic valves. The switch of the moving directions of the left holding fork oil cylinder and the right holding fork oil cylinder is achieved through operation of the reversing valves. The transverse holding fork auxiliary linkage single-handle operation device has the beneficial effects that operation conducted through the single handle is achieved through the function switching switch, operation comfort is improved, and meanwhile manufacturing cost is reduced.
