[0021] Specifically, the butterfly rotating head drives the positive and negative lead screws 7 to rotate, and the rotation of the positive and negative lead screws 7 drives the T-shaped slider 8 to move towards the center or both sides. The movement of the T-shaped slider 8 drives the movement of the positioning plate 6, and the positioning plate 6 can position and fix the printed circuit board.

[0022] according to Figure 1 , Figure 2 and Figure 3 As shown, this utility model discloses a printed circuit board processing bracket.
