Furthermore, the rotating handle 1 is a linear handle.
Furthermore, the plugging net 4 is composed of latticed iron nets or plastic nets, and the distance between the grids is 0.5-5 cm.
Further, the support rod 5 is plate-shaped.
Further, the outer protective cylinder 7 is made of steel or plastic steel and has a diameter of 15-40 cm.
Further, the direction converter 8 is a 90-degree gear steering.
Compared with the prior art, the invention has the following advantages:
because the simple operations such as rotating the rotating handle 1, extruding the supporting rod 5, opening the plugging net 4 and the like are adopted, the problem that the plugging material is washed away by water flow in the prior art is solved, and the plugging efficiency is greatly improved; meanwhile, the device provided by the invention is simple in structure, convenient to operate, capable of saving manpower and material resources and wide in application range.
