[0003] For example, the welding support for steel structure grid processing with the publication number CN202322461465.4 includes a base and columns. The upper surfaces at both ends of the base are symmetrically provided with columns. The center position inside the base is rotatably connected with a central turntable. A moving groove is arranged inside the central turntable. A bidirectional screw is arranged inside the moving groove. Threaded sliders are threadedly connected to both ends of the bidirectional screw. A motor is arranged below the moving groove. A first gear is arranged at the output end of the motor. The first gear is meshed and connected with a second gear.
