[0026] The effect achieved by the entire embodiment 1 is that after the hose 408 is connected to the external water pipe, the valve switch 409 can be opened to ensure that the water source can enter the two sets of fixed water pipes 403 through the hose 408, and then the water source is sprayed out through the atomizing nozzle 404, so as to reduce the dust inside the tunnel. At the same time, when it is necessary to adjust the position of the two sets of cross bars 410 according to actual conditions, the handle 407 can be turned to drive the bidirectional screw 405 to rotate, and the bearing 406 can improve the stability of the bidirectional screw 405 when rotating. When the bidirectional screw 405 rotates, the threaded holes and the two sets of cross bars 410 will rotate at the same time, and then the two sets of cross bars 410 will be driven to move by the threaded rotation, so as to realize the movement of the atomizing nozzle 404.
