[0020] Wherein, the grid pipe section is welded and fixed to the steel socket, and the steel socket has an end face portion connected to the grid pipe section. The end face portion has a small diameter hole, which is smaller than the large diameter of the steel socket and smaller than the diameter of the duct, and is perpendicular to the axis of the duct to facilitate connection with the grid pipe section.

[0021] In some embodiments, a plurality of reinforcing plates 2 are arranged on the outer surface of the grid tube segment, such as Figure 1 As shown, the reinforcing plate can be evenly or unevenly arranged on the outer surface of the grid pipe segment, wherein the bottom of the reinforcing plate is connected to the end surface of the steel socket to achieve the reinforcing function and effect, and can be a trapezoidal plate.

[0022] In some embodiments, Figure 1 , 2The end of the end face of the steel socket is provided with an arc-shaped fixed baffle 10, and the other side thereof is provided with an arc-shaped movable baffle 3. Through the action of the fixed baffle and the movable baffle, the plug rod can be fixed to prevent it from slipping or falling out.
