Then the slide bar is released to fix the rust removal device. This fixing method does not require the use of bolts to install and disassemble the rust removal device, making the replacement process more convenient and quick, reducing the labor intensity of maintenance personnel, reducing the time required for device maintenance and updating, and improving the working efficiency of the device.
