[0029] It is worth mentioning that the lateral limiting mechanism includes a limiting groove 14, which is evenly arranged inside the operating box 8. A circular plate 15 is slidably installed inside the limiting groove 14, and a pressure spring 16 is fixedly arranged between the opposite surfaces of the circular plate 15 and the limiting groove 14, which is used to drive the circular plate 15 to reciprocate; a connecting rod 17 is fixedly installed on the side of the circular plate 15 away from the pressure spring 16, and a clamping plate 18 is fixedly installed on one end of the connecting rod 17, which is used to laterally fix the side of the circuit board, and the longitudinal length of the clamping plate 18 is less than the longitudinal length of the clamping mouth 12, which is used to facilitate the extension and retraction of the clamping plate 18; the cross-section of the clamping plate 18 is an octagonal structure, and is symmetrically distributed with the connecting rod 17 as the center, and grooves 19 are opened on the opposite surfaces of the clamping plate 18, and rubber pads are arranged inside the grooves 19, which are used to protect the side of the circuit board and avoid damage to the circuit board.

[0030] Further examples:

[0031] Please refer to Figures 1 to 7As shown, slide bars 9 are fixedly provided on both sides of the operation box 8, and connecting plates 10 are slidably installed between the outer surfaces of the slide bars 9, and reset springs 11 are provided between the connecting plates 10 and the inner wall of the operation box 8, and the reset springs 11 are sleeved on the outer surfaces of the slide bars 9; there are two connecting plates 10, and they are symmetrically distributed with the clamping plate 18 as the center, and the two connecting plates 10 are adapted to the clamping opening 12; wherein, the two connecting plates 10 are both fitted to the inner side of the clamping opening 12 to ensure that the two connecting plates 10 can clamp the upper and lower sides of the circuit board to avoid the connection plates 10 being unable to clamp due to the small gap on the side of the circuit board, and the opposite surfaces of the two connecting plates 10 are provided with protrusions 13, and the cross-section of the protrusions 13 is a trapezoidal structure, the protrusions 13 are adapted to the clamping plate 18, and the protrusions 13 can move with the movement of the clamping plate 18; the outer surfaces of the protrusions 13 are provided with rubber pads.

[0032] Everything in the above example works like this:

At the same time, the rubber pad arranged on the groove 19 can play a buffering and protective role for the circuit board to prevent the side of the circuit board from being squeezed and damaged. Then, the servo motor 4 is controlled to start through the operation panel 3 to start working and drive the ball screw 5 to rotate. Then the ball screw 5 drives the operation box 8 to move along the limit rod 6, so that the two operation boxes 8 move relative to each other. When the other side of the circuit board to be tested contacts the other clamping plate 18, similarly, the circuit board to be tested fits with the groove 19 on the clamping plate 18. At this time, the two clamping plates 18 are subjected to force and push the circular plate 15 to slide along the inside of the limit groove 14 through the connecting rod 17, and push The dynamic pressure spring 16 is continuously contracted, and the two sides of the circuit board extend into the clamping opening 12 on the operating box 8, so that the circuit board can be clamped and fixed quickly, accurately and efficiently, and it can also adapt to circuit boards of different specifications, thereby improving the practicality of the device; as the two clamping plates 18 are continuously extended, the upper and lower surfaces of the clamping plates 18 with an octagonal structure gradually separate from the protrusions 13 on the connecting plate 10, and under the elastic action of the reset spring 11, the connecting plate 10 pushes the protrusions 13 to slide relatively along the slide bar 9, so that the protrusions 13 on the two clamping plates 18 clamp the upper and lower surfaces of the circuit board, thereby realizing multi-directional clamping of the circuit board, avoiding displacement or loosening of the circuit board during the production and detection process, thereby improving the stability of the fixing device, thereby improving the accuracy and reliability of the detection results.
