In this article, when the operator is working on the top of the foundation ring, he first docks the installation arm with the bottom of the flange end of the foundation ring, controls the clamping arm to slide up and down to clamp the flange end of the foundation ring, so that the movable clamping balls inside the installation arm and the clamping arm can be limitedly engaged with the limiting ring groove inside the flange end of the foundation ring, and controls the rotation and movement of the top pressing screw by the control handle, so that the bottom of the top pressing screw limits the clamping arm, thereby ensuring the sliding stability between the installation arm and the clamping arm and the flange end of the foundation ring. When the operator is located at the top of the foundation ring for moving operations, the operator can be supported by the support rod inside the support plate, so that when the operator moves, the support plate above the installation arm can cooperate with the operator to move and provide corresponding support, provide a support point for the operator, and ensure the stability of the operator's movement, thereby achieving the effect of improving the protection of the operator himself and ensuring the safety of the operator's operation.
[0014] 2.
