2. Slowly and carefully rotate around the waste screw with one side of the small scissors, and dig out the small plastic circle around the screw.

3. Make sure that after all the plastic next to it is dug out, unscrew other good screws with a plum blossom screwdriver, and wrap all the unscrewed screws with a piece of paper and put them away to prevent them from being lost.

4. Don't put the scissors in the gap on the side, use some force to tilt the whole cover up, and then take it off.
