Steel structured support frame

The invention discloses a steel structured support frame. The steel structured support frame comprises a support frame base; a buffer damping device is fixedly mounted on the support frame base; the buffer damping device consists of a spring base, a piston rod, a damping spring, a spring top base, a bolt, a hexagonal nut and a locking nut; the piston rod is mounted on the spring base; the dampingspring is mounted on the piston rod; the bottom of the damping spring is contacted with the spring base; the top of the damping spring is contacted with the spring top base; the damping spring is mounted between the spring base and the spring top base; the piston rod penetrates through the spring top base; the bolt is arranged at the upper part of the piston rod; and the hexagonal nut is mounted on the bolt, is arranged on the upper surface of the spring top base, and is contacted with the upper surface of the spring top base. The steel structured support frame is simple in structure and low in manufacturing cost, ach
