[0025] In actual use, the above structure involves introducing magnetic powder into the storage bin 9, then placing one end of the axle to be inspected against the first clamping plate 4. The second motor 13 is then activated, driving the second screw 12. The second screw 12 rotates, driving the moving plate 14. The moving plate 14, through the connecting plate 15, drives the second clamping plate 17, causing one side of the second clamping plate 17 to press against the other end of the axle, thus fixing the axle. The storage bin 9 then sprays the axle with nozzles 10 for inspection. During the spraying process, the first motor 6 is activated, driving the first screw 5.
