When the mounting shaft is rotated by the bounce of the cleaning blade 3, the spring 74 will be compressed, and in the process, the spring 74 will absorb the excessive moment generated by the bounce process, thereby protecting the pressure sensor 6. Accordingly, the worker can adjust the initial elastic potential energy inside the spring 74 by adjusting the position of the nut 73, so that the device is suitable for different working conditions.
