Scissor type lifting arch frame machine

The utility model discloses a shears-fork type lifting arch frame machine which comprises a trolley, a lifting platform is arranged on the trolley, and a lifting assembly is arranged between the lifting platform and the trolley. A lifting arm set is arranged on the lifting table and comprises a first rotating block, a second rotating block and a lifting arm, one end of the rotating arm is hinged to the first rotating block; the second rotating block is hinged to the end, away from the first rotating block, of the rotating arm. In the utility model, the rotating angle of the rotating arm relative to the first rotating block is equal to the rotating angle of the second rotating block relative to the rotating arm, and the rotating directions of the rotating arm and the second rotating block are opposite, so that the rotation of the rotating arm relative to the first rotating block and the rotation of the second rotating block relative to the rotating arm can be counteracted; therefore, the bracket assembly does
