A dust shield is installed on the steering knuckle of a certain model, and the dust shield is fixedly connected to the steering knuckle by bolts. During assembly, the traditional assembly method is that the assembler tightens the bolts with a wrench, and the wrench is separated from the assembly production line. If the position is changed, the wrench is forgotten to be put in the designated position or is not handed over to the successor, and moves with the pre-operation staff, resulting in the subsequent successors looking for wrenches, which affects work efficiency and is not conducive to the continuous operation of the production line.
