The height of the arc-shaped clamping sheet is 3-5cm. When installed and used, the middle parts of the arched outer surfaces of the two arc-shaped clamping sheets are close to each other; and the two ends of the arc-shaped clamping sheets are rotatably connected in the collection frame through the shaft 4, and the shaft is above the center line of the arc-shaped clamping sheet; the distance between the two shafts is greater than the thickness of the circuit board. Since the shaft is above the center line, the center line of the arc-shaped clamping sheet can be clamped together, and the circuit board can be clamped and positioned when the circuit board is inserted. At the same time, the supporting piece is at the bottom of the two arc-shaped clamping pieces, and the spring is fixed between the supporting piece and the arc-shaped clamping piece; through the above structure, the supporting piece is mainly used to support the lower edge of the circuit board, and the spring is mainly used to increase the deformation force to ensure the stability and reliability of clamping the circuit board. During use, the circuit board is inserted from the top of the two arc-shaped clamping pieces and is clamped and limited under the action of the spring.

[0025] At the same time, a stop convex strip 5 is provided on the symmetrical edge of the top surface of the carrier sheet; the bottom edge of the circuit board is inserted between the two stop convex strips. In this embodiment, the width between the stop convex strips matches the thickness of the circuit board, the carrier sheet is a plastic structure, and the width of the carrier sheet matches the thickness of the circuit board. The bottom edge of the circuit board can be supported and clamped.

[0026] The utility model has positive effects: the structure of the utility model is reasonably arranged, and the arc-shaped clamping piece cooperates with the bearing piece and the spring, and the center of the arc-shaped clamping piece is connected through an axle rod. When in use, the circuit board is inserted from the top of the two arc-shaped clamping pieces, and the two arc-shaped clamping pieces are rotated with the axle rod as the center, and the lower part is unfolded downward and the spring is stretched.
