[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention, through the design of a cleaning drive mechanism, allows the sandblasting placement piece to be removed after screw processing. Rotating the retrieval operation piece causes the cleaning drive disc to move upwards, which in turn moves the cleaning ejector rod upwards. This upward movement of the cleaning ejector rod then moves the cleaning ejector piston upwards, ejecting all the screws and facilitating their removal. Simultaneously, the upward movement of the cleaning ejector piston removes any remaining sand fragments from the sandblasting placement holes, ensuring the cleanliness of the entire sandblasting placement piece and facilitating its future use, thus improving the overall effectiveness of the sandblasting fixture.

[0015] This invention utilizes a picking-up driving mechanism. The picking-up driving component is compressed and moves upwards, pulling the picking-up transmission rope. Under the action of the picking-up guide wheel, the picking-up transmission rope drives the picking-up filter to move downwards. The downward movement of the picking-up filter compresses the picking-up connecting spring, which is then energized. When a screw needs to be picked up, the sandblasting placement piece is lifted, and the picking-up driving component is no longer compressed. Under the action of the picking-up connecting spring, the picking-up filter moves upwards. After the picking-up filter reaches the top, the ejected screw tilts towards the picking-up filter, effectively filtering residual sand from the screw surface, ensuring the screw's cleanliness and facilitating subsequent reprocessing.
