Scissor fork type lifting working platform

The utility model discloses a shear fork type lifting working platform, and relates to the technical field of lifting working platforms. The scissor fork type lifting working platform comprises a lifting mechanism, a lifting oil cylinder, a triggering mechanism and a walking mechanism, wherein the lifting mechanism comprises a plurality of layers of mutually hinged fork frames. The lifting oil cylinder is arranged in the lifting mechanism and used for driving the lifting mechanism to ascend and descend. The fixed end and the telescopic end of the lifting oil cylinder are hinged to the fork frames of different layers respectively, and the fork frame hinged to the telescopic end is higher than the fork frame hinged to the fixed end. When the distance between the fork frame hinged to the telescopic end and the adjacent fork frame located below the fork frame hinged to the telescopic end is equal to the preset distance, the trigger mechanism is switched from the trigger state to the non-trigger state. The walking
