The shot blasting machine for processing a high voltage transformer housing according to claim 7, characterized in that: An elastic member installation groove (38) is provided on the side wall of the annular installation groove (30), a spring groove (47) is provided on the outer end side wall of the elastic member installation groove (38), an elastic member (39) is provided in the elastic member installation groove (38), the elastic member (39) is cast from spring steel, and the elastic member (39) is provided in an L-shape, a transverse plate of the elastic member (39) is fixedly glued to the inner end surface of the elastic member installation groove (38), a supporting spring (40) is fixedly glued to the outer end of the elastic member (39), the supporting spring (40) is movably provided in the spring groove (47), and a limiting protrusion (41) and a force-bearing protrusion (42) are integrally formed on the side wall of the vertical plate of the elastic member (39).

9. A shot blasting machine for processing a high voltage transformer housing according to claim 8, characterized in that: The limiting protrusion (41) and the force-bearing protrusion (42) are both wedge-shaped. When a wrench is inserted into the gap between the nut groove (20) and the positioning nut (24), the force-bearing protrusion (42) is forced to be retracted into the elastic member installation groove (38). At this time, the elastic member (39) is deformed under force to allow the limiting protrusion (41) to be retracted into the elastic member installation groove (38). When the steel ball of the shot blasting machine enters the gap between the nut groove (20) and the positioning nut (24), the steel ball of the shot blasting machine cannot come into contact with the force-bearing protrusion (42).

10. The shot blasting machine for processing a high voltage transformer housing according to claim 9, characterized in that: A protective lining plate (43) is detachably mounted on the inner side wall of the shot blasting machine housing (1) via a screw structure.
