Turnout mechanism and rail system

The invention discloses a turnout mechanism and a rail system. The turnout mechanism comprises a base plate, base rails, switch rails and connecting assemblies; the base rails are arranged on the baseplate; one ends of the switch rails are fixedly connected with the base plate, and the other ends of the switch rails are in a bent state to be attached to the base rails so that the switch rails hasa movement trend towards one sides of the base rails; and the connecting assemblies are arranged on the base plate, and the base rails and the switch rails are fixed to the base plate through the connecting assemblies. According to the turnout mechanism and the rail system, the structure of the switch rails is optimized, the conventional press-type processing on heel ends of the switch rails is eliminated, the heel ends of the switch rails are subjected to bending processing, the resilience force generated by bending of the switch rails is used for reducing insufficient displacement, the tight fit of the switch rails
