A slot is opened on one side of the support column, and an umbrella-shaped movable block can be movably connected to it. This design allows the umbrella-shaped movable block to move flexibly in the slot and adjust its position as needed. In this way, when processing drill pipe welding areas of different sizes or shapes, it can be better adapted and fixed.
