By setting the rotating block 19 to be rotatably connected to the rotating hole, rotating the display 20 causes the rotating block 19 to rotate on the support frame 18, thereby adjusting the viewing angle of the display 20 and facilitating observation of the display 20 from different angles.

[0029] In this embodiment, as Figure 1 As shown, the connecting assembly includes a support column 3 and a top plate 26. Support columns 3 are installed on both sides of the body 1, and a top plate 26 is installed at one end of the support column 3. By setting the support column 3 and the top plate 26 to cooperate with each other, the support frame 18 can be easily supported. Multiple support legs 2 are installed at the bottom of the body 1. By setting the support legs 2, the body 1 can be easily supported.

[0030] In this embodiment, as Figure 1 , Figure 3 and Figure 7 As shown, the clamping assembly includes a first hydraulic telescopic rod 4, a movable plate 8, a movable rod 9, and a clamping frame 10. The first hydraulic telescopic rod 4 is mounted on the support column 3. The movable plate 8 is mounted on the output end of the first hydraulic telescopic rod 4. The movable rod 9 is mounted on the bottom of the movable plate 8. The clamping frame 10 is mounted on one end of the movable rod 9. A support ring 7 is mounted on the support column 3. A side column 6 is mounted on the support ring 7. A support frame 5 is mounted on one end of the side column 6. The first hydraulic telescopic rod 4 is mounted on the support frame 5. A connecting ring 11 is mounted on the support column 3. A connecting rod 12 is mounted on the connecting ring 11. A connecting frame 13 is mounted on one end of the connecting rod 12. The camera assembly includes a second hydraulic telescopic rod 14, a vision camera 15, a top rod 17, a slider 27, and a guide rod 28. The second hydraulic telescopic rod 14 is mounted on the connecting frame 13. The vision camera 15 is mounted on the output end of the second hydraulic telescopic rod 14. The device is equipped with a top rod 17, one end of which is fitted with a slider 27. A guide rod 28 is mounted on the top plate 26. The slider 27 has a sliding hole that cooperates with the guide rod 28. By setting a first hydraulic telescopic rod 4, the clamping frame 10 can be moved to clamp the power module. By setting a second hydraulic telescopic rod 14, the vision camera 15 can be moved to capture images of the module and transmit them to the display 20, making it easy for staff to observe the power module. The first hydraulic telescopic rod 4 can be supported by the cooperation of the support frame 5, side column 6, and support ring 7. The second hydraulic telescopic rod 14 can be supported by the cooperation of the connecting ring 11, connecting rod 12, and connecting frame 13. The vision camera 15 can be guided and limited by the sliding connection between the slider 27 and the guide rod 28.

[0031] In this embodiment, as Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the guide assembly includes a slide rod 23, a moving ring 25, and a base column 22. The slide rod 23 is mounted on the support frame 18, the moving ring 25 is slidably mounted on the slide rod 23, and the base column 22 is mounted on the moving ring 25. The limiting assembly includes a limiting plate 21 and a plug rod 29. The limiting plate 21 is mounted on one end of the base column 22, and the plug rod 29 is mounted on the limiting plate 21. The rotating block 19 has multiple slots that cooperate with the plug rod 29. The moving ring 25 is connected to the slide rod 23 through a spring 24. When the limiting plate 21 is released, the spring 24 extends, thereby driving the moving ring 25 to move and insert the plug rod 29 into the slot, which can limit the adjusted display 20. By setting the slide rod 23 and the moving ring 25 to slide together, it is easy to guide and limit the limiting plate 21.

[0032] In this embodiment, as Figures 1-7 As shown in the figure, the working process of the conductivity detection device for power modules provided in this embodiment is as follows:

[0033] Step 1: The first hydraulic telescopic rod 4 is activated, which moves the clamping frame 10 to clamp the power module. The second hydraulic telescopic rod 14 is activated, which moves the vision camera 15 to take pictures of the power module. The staff holds a test pen to test the power module.

[0034] Step 2: Rotate the display 20, the rotating block 19 rotates on the support frame 18, release the limiting plate 21, the spring 24 extends, and then drives the moving ring 25 to move, inserting the plug rod 29 into the slot to limit the adjusted display 20.

[0035] In summary, in this embodiment, the conductivity detection device for the power module, by setting a rotating block 19 rotatably connected to a rotating hole, allows the display 20 to be rotated, and the rotating block 19 rotates on the support frame 18, thus adjusting the viewing angle of the display 20 and facilitating observation of the display 20 from different angles. The support column 3, in cooperation with the top plate 26, facilitates support of the support frame 18. The support leg 2 facilitates support of the body 1. The first hydraulic telescopic rod 4, when activated, moves the clamping frame 10 to clamp the power module. The second hydraulic telescopic rod 14, when activated, moves the vision camera 15 to monitor the module. The image is captured and transmitted to the display 20, which facilitates the observation of the power module by the staff. The support frame 5, side column 6 and support ring 7 cooperate to support the first hydraulic telescopic rod 4. The connecting ring 11, connecting rod 12 and connecting frame 13 cooperate to support the second hydraulic telescopic rod 14. The slider 27 and guide rod 28 are slidably connected to guide and limit the vision camera 15. When the limit plate 21 is released, the spring 24 extends, which drives the moving ring 25 to move. The insertion rod 29 is inserted into the slot to limit the adjusted display 20. The sliding rod 23 and moving ring 25 are slidably connected to guide and limit the limit plate 21.
