After the two steel pipes are placed, the operator energizes and starts the electric push rod 22, and the electric push rod 22 pushes the support bracket 26, so that one side of the support bracket 26 is in contact with the surface of the steel pipe. At this time, the support bracket 26 and the clamping plate 27 cooperate with each other to clamp the steel pipe in a multi-point manner, thereby completing the clamping operation of the steel pipe.
