One end of the connecting seat 5 is rotatably installed at the lower end of the telescopic rod 4. A connecting rod 6 is rotatably installed at the other end of the connecting seat 5. A mounting seat 7 is fixedly installed at the bottom of the connecting rod 6. A mounting plate 8 is slidably installed on the mounting seat 7. A base 9 is fixedly installed at one end of the bottom of the mounting plate 8. A probe 10 is arranged on the base 9. During the flying probe test, the initial height of the probe 10 can be adjusted by the telescopic rod 4 and the telescopic sleeve 3, so as to facilitate the testing of PCB boards with different thicknesses, greatly improving the versatility and flexibility of the equipment; the lower end of the telescopic rod 4 is rotatably connected to one end of the connecting seat 5. The other end of the connecting seat 5 is rotatably installed with a mounting seat 7 through the connecting rod 6. A mounting plate 8 is slidably installed on the mounting seat 7. The test probe is arranged at one end of the bottom of the mounting plate 8 through the base 9. The design of the connecting seat 5, the connecting rod 6, the mounting seat 7 and the mounting plate 8 allows the probe 10 to be flexibly adjusted in multiple directions, which enables the probe 10 to easily access various test points on the PCB board, whether they are conventional or difficult to access, and efficient testing can be achieved. By adjusting the initial height of the probe 10 and the multi-directional adjustment function, the tester can quickly adapt to different PCB boards, reducing the preparation time before testing. At the same time, the precise positioning of the probe 10 ensures the accuracy of the test and improves the test efficiency; the flexibility enables the tester to easily cope with various complex test requirements and improves the flexibility of the test; when testing on a complex PCB board, the rotation and telescoping of the probe 10 in the air can avoid collisions with other components or test equipment, reducing the risk of equipment damage.

[0026] A first motor 11 is fixedly installed at the top of the mounting bracket 2. A nut 12 is installed on the telescopic rod 4, and a lead screw 13 is arranged inside the telescopic sleeve 3. One end of the lead screw 13 is fixedly connected to the output end of the first motor 11, and the other end of the lead screw 13 is threadedly connected to the nut 12; two sliders 14 are evenly installed on the telescopic rod 4, and two chutes 15 matching the sliders 14 are formed on the telescopic sleeve 3. When the first motor 11 is started, it drives the lead screw 13 to rotate. Due to the threaded connection between the nut 12 and the lead screw 13, when the lead screw 13 rotates, the nut 12 will perform a linear motion along the lead screw 13. The nut 12 is fixed on the telescopic rod 4, so the telescopic rod 4 will move up and down with the linear motion of the nut 12. At the same time, the sliders 14 slide in the chutes 15, playing a role in guiding and stabilizing the movement of the telescopic rod 4; the combination of the first motor 11 and the lead screw 13 transmission can achieve precise control of the lifting of the telescopic rod 4, thereby precisely adjusting the initial height of the probe 10; the cooperation between the sliders 14 and the chutes 15 ensures the stability of the lifting of the telescopic rod 4, avoiding deviation or shaking during the lifting process; this device can adapt to PCB boards of different thicknesses for testing, and this design improves the versatility and flexibility of the equipment, enabling the same device to be used for testing a variety of different types of PCB boards.

[0027] A first gear 16 is fixedly installed at the lower end of the telescopic sleeve 3. A second gear 17 is rotatably installed at the top of the connecting seat 5. The first gear 16 and the second gear 17 are meshed and connected. A second motor 18 is installed at the bottom of the connecting seat 5, and the output end of the second motor 18 is fixedly connected to the second gear 17. When the second motor 18 is started, it drives the second gear 17 to rotate. Since the first gear 16 is fixedly installed on the telescopic rod 4, the second gear 17 drives the connecting seat 5 to rotate along the center of the telescopic rod 4. Through precise control of the second motor 18, precise control of the rotation of the connecting seat 5 in the horizontal direction can be achieved, quickly and accurately adjusting the orientation of the probe 10, reducing the time for manual adjustment, thereby improving the testing efficiency. Through the rotation of the connecting seat 5, the testing probe 10 can cover a larger working range, thereby improving the versatility and flexibility of the equipment, which enables the same device to adapt to more PCB boards of different sizes, shapes and layouts.

[0028] A third motor 19 is fixedly installed at the top of the connecting base 5, and the output end of the third motor 19 is fixedly connected to the connecting rod 6; a fourth motor 20 is fixedly installed at the rear end of the mounting base 7, a third gear 21 is rotatably installed inside the mounting base 7, the output end of the fourth motor 20 is fixedly connected to the third gear 21, and a rack 22 is fixedly installed at the top of the mounting plate 8. The third gear 21 and the rack 22 are meshed and connected. When the third motor 19 is started, it directly drives the connecting rod 6 to rotate. The rotation of the fourth motor 20 drives the rotation of the third gear 21. When the third gear 21 rotates, due to the meshing relationship with the rack 22, it drives the mounting plate 8 to perform a linear motion; through the precise control of the connecting rod 6 by the third motor 19 and the fourth motor 20, precise positioning and operation of the test probe can be achieved. The test equipment can adapt to PCB boards of different sizes, shapes, and layouts for testing, enhancing the versatility and flexibility of the equipment, significantly improving the automation level of the test process, reducing manual intervention and operation time, and improving the test efficiency.

The top of the probe 10 passes through the fixed sleeve 23 and extends into the inner cavity of the base 9. A fixing plate 27 is installed on the probe 10, and the fixing plate 27 is arranged between the limiting plate 25 and the fixed cover 24. When the probe 10 contacts the PCB board, due to the existence of the limiting spring 26, the probe 10 can generate a certain elastic deformation, thus avoiding the rigid contact between the probe 10 and the PCB board and reducing the possible damage to the PCB board during the test process; when the probe 10 needs to be replaced, only need to unscrew the fixed cover 24, then the probe 10 together with the fixing plate 27 can be taken out from the fixed sleeve 23. Then, insert the new probe 10 into the fixed sleeve 23 and the base 9 and reinstall the fixed cover 24. This design greatly simplifies the operation steps of replacing the probe 10 and improves the work efficiency.
