Fix the jewelry on the rotating ball seat of the fire paint ball with fire paint glue, adjust the height of the rotating ball seat by moving the lifting structure in the bracket assembly, control the distance between the jewelry surface to be sandblasted and the sandblasting head, turn on the sandblasting head, and sandblast the jewelry. As the sandblasting proceeds, you only need to move the second slider on the horizontal plane in the longitudinal and lateral positions by hand from time to time, or rotate the rotating ball seat relative to the concave spherical surface of the base to change the sand contact point of the sand sprayed by the sandblasting head on the jewelry, and the sandblasting steps of a single surface of the jewelry can be completed. This method does not require manual holding of the jewelry throughout the process, saves manpower, and is easy to operate. This method is suitable for sandblasting relatively flat surfaces such as the end plane of the ring, and the ring is horizontally bonded to the fire paint glue.

[0018] 2. For example, when sandblasting the curved surface of a ring, the sandblasting head needs to be rotated to a horizontal position through the rotating assembly, with the sandblasting head facing the curved surface of the ring. The position of the rotating assembly can be locked using a position locking structure to prevent the sandblasting head from shaking and improve sandblasting stability. During the sandblasting process, manually rotating the rotating ball seat at regular intervals can drive the ring to rotate by an angle, gradually completing the sandblasting operation of the curved surface of the ring, saving manpower and facilitating operation.

[0019] 3. When operating the position locking structure, hold the handle of the rotating assembly and use the index and middle fingers to press the operating panel to the side of the handle to disengage the latch from the pin hole on the box. At this time, you can rotate the rotating assembly and adjust the rotation angle of the sandblasting head. After rotating to the right position, release the operating panel with your fingers and insert the latch into the position of a pin hole on the box to complete the locking of the rotating assembly position. This structure is easy to operate and can be completed with one hand.
