A circular surrounding wall is fixedly arranged on the peripheral edge of the top of the bottom shell. A plurality of first anti-loosening barbs are arranged on the outer side wall of the annular cover, and a plurality of second anti-loosening barbs are arranged on the inner side wall of the circular surrounding wall. When the annular cover covers the spherical cavity, the plurality of first anti-loosening barbs and the plurality of second anti-loosening barbs are engaged with each other.

[0005] In the stamping and assembled universal ball of the utility model, an opening through which the ball can pass is arranged at the center of the annular cover, and the diameter of the opening is smaller than the diameter of the ball.

[0006] In the stamping and assembled universal ball of the utility model, the annular cover includes an annular connecting part connected to the circular surrounding wall and an annular inclined part fixedly arranged on the top of the annular connecting part. The plurality of first anti-loosening barbs are arranged on the outer side wall of the annular connecting part. The annular inclined part is used to block the ball, and the annular inclined part extends gradually from the bottom end to the top end towards the center of the annular cover.

[0007] In the stamping and assembled universal ball of the utility model, an external thread is arranged on the connecting column, and a nut that can be rotatably sleeved on the external thread and is screwed with the external thread is arranged.

[0008] In the stamping and assembled universal ball of the utility model, an insertion hole for inserting and connecting the end of the connecting column is arranged at the center of the bottom of the bottom shell. After the end of the connecting column is inserted into the insertion hole, the peripheral wall of the insertion hole is fixedly welded to the connecting column.

[0009] Implementing the stamping and assembled universal ball of the present utility model has the following beneficial effects: When assembling the stamping and assembled universal ball of the present utility model, first place a plurality of balls in the spherical cavity, then place the sphere in the spherical cavity, and finally cover the sphere with the annular cover and align it with the annular surrounding wall. Use a stamping device to stamp the annular cover downward, so that the annular cover moves downward, and a plurality of first anti-disengagement barbs and a plurality of second anti-disengagement barbs engage with each other, which can prevent the annular cover from disengaging from the bottom shell and achieve a better stable connection effect. Further, by providing the connecting column, it is more convenient to fixedly connect the universal ball to the tabletop or other objects, so that the universal ball can be used more widely.
