Motor six 42 drives the bidirectional screw rod 43 to rotate. The rotation of the bidirectional screw rod 43 drives the two sliders 44 to move closer to each other in the rectangular groove 45. The two sliders 44 move closer to each other and clamp the circuit board on the support plate 8 through the clamping plate 41. At the same time, an anti-skid pad 46 is arranged at one end of the clamping plate 41 to play an anti-skid role. By setting the positioning component 4, the circuit board placed on the support plate 8 can be positioned and fixed to prevent the circuit board from being easily displaced on the support plate 8 when the support plate 8 rotates and affecting the exposure work. When the support plate 8 rotates, the ball 49 in the round seat 48 at the lower end of the several rotating shafts 47 at the lower end of the support plate 8 rolls at the lower end of the box body 1, and the ball 49 rolls in the rolling groove of the round seat 48. By setting the rotating shaft 47, etc., the rotation of the support plate 8 can be supported, so that the rotation of the support plate 8 is more stable.
