The limiting groove 4 can improve the stability of the clamping plate 5, which is convenient for the subsequent clamping and fixing of the circuit board body 13.

[0022] In this embodiment, slide grooves 7 are symmetrically opened at the middle positions on both sides of the top of the base 1, and a slide rod 11 is installed with a limited sliding inside the slide groove 7. An annular groove 10 is opened on the top of the elliptical disk 9, and the bottom end of the slide rod 11 is slidably installed inside the annular groove 10. The slide rod 11 is fixedly set at the center position of the top of the clamping plate 5, and the two ends of the clamping plate 5 are limited and slidably installed inside the limiting groove 4. The shape of the fixing frame 3 is "L" type, and the limiting groove 4 is symmetrically opened on both sides of the top of the fixing frame 3. The elliptical disk 9 drives the annular groove 10 to rotate, and the annular groove 10 drives the clamping plate 5 to slide inside the limiting groove 4 through the slide rod 11, so that the clamping plates 5 on both sides are close to each other, which is convenient for clamping and fixing the circuit board body 13 through the clamping plates 5 on both sides.

[0023] In this embodiment, a rubber block 6 is fixedly provided on one side of both ends of the clamping plate 5, and a slope is provided on one side of the rubber block 6. A circuit board body 13 is clamped between the rubber blocks 6. A fixing rod 12 is fixedly installed on one side of both ends of the clamping plate 5 corresponding to the bottom of the rubber block 6.
