Protective net supporting frame

The utility model relates to the technical field of protective nets, in particular to a protective net supporting frame which is characterized in that a hollow block is fixedly connected to one side of a first cross rod, a through groove is formed in the hollow block, a moving mechanism is arranged in the through groove and can move in the through groove, and the side, close to the hollow block, of each blocking net extends into the through groove; and the hollow block is connected with the moving mechanism through the clamping mechanism, the moving mechanism is rotatably connected with the hollow block, and a limiting mechanism is arranged between the moving mechanism and the hollow block. According to the device, the two blocking nets can be partially wound on the two mounting plates conveniently, the rotation angle of the connecting rod can be conveniently limited through the protruding block and the clamping groove in one side of the connecting block, and therefore the tensioning degree of the blocking ne
