it can start normally now, and Win10 recognition (identified as U disk, after the prompt can be safely removed) , but the driver can not be ejected, whether it is enclosure button or driver button, and I notice that the driver is not on. How can I save? He is past the warranty.

Well going by the second picture that PCb board is blocking it.
But if still nothing after that see on the left side that small hole that's the emergency eject use a paper clip on that.
If the drive still works normally with manual ejecting and closing you can check in the rubber belt broke for the door if so replace it and it should be fixed.
