The top of the triangular slide block 5 is slidably connected with the sliding column 6, which serves as an intermediate bridge connecting the triangular slide block 5 and the push plate 7, and plays a dual role of force transmission and motion guidance. It transmits the vertical force from the triangular slide block 5 to the push plate 7 without loss, so that the push plate 7 can move up and down accurately according to the action of the electric push rod 4. The top of the sliding column 6 is fixedly connected with the push plate 7, which pushes the spray pipe 12, and the spray pipe 12 drives the sliding barrel 8 to move up and down. The inside of the push plate 7 is fixedly connected with the spray pipe 12, the top of the spray pipe 12 is fixedly connected with the sliding barrel 8, and the sliding barrel 8 is an important component for transmitting and pressure regulating the deicing agent. During the movement of the push plate 7, the sliding barrel 8 can slide elastically in the vertical direction according to the road conditions and operation requirements. The top of the sliding barrel 8 is fixedly connected with the spring 9, which provides elastic support and buffer for the whole system. During normal operation, the spring 9 is in a certain compression or stretching state, providing upward support force for the sliding barrel 8 to balance the gravity and other external forces of the push plate 7 and other components. When the spring 9 is compressed, the deicing agent will slide out of the groove of 8. When not needed, the spring 9 is compressed to return the sliding barrel to its original position. The top of the spring 9 is fixedly connected with the fixed box 13, which provides a stable operating environment and motion guide frame for the sliding barrel 8, the spray pipe 12 and other components.

The front side of the square sliding block 20 is fixedly connected with the connecting block 23, the connecting block 23 ingeniously fuses and converts the linear motion of the square sliding block 20 and the arc-shaped motion of the sliding block two 22 into the angle adjustment motion of the blade 24. The opposite sides of the connecting block 23 are fixedly connected with the sliding block two 22, the connecting arc-shaped sliding block 21 and the connecting block 23, and the sliding on the arc-shaped sliding block 21 directly affects the angle of the blade 24.
