A connecting rod 13 is fixedly connected to the outer surface of the slide bar 12. A connecting groove 14 is provided on the lower surface of the connecting rod 13. A probe 15 is fixedly connected to the upper surface of the connecting rod 13.

[0024] Furthermore, the guide sleeve 1 is cylindrical in shape and hollow inside. The connecting rod 13 is rod-shaped and slidably connected inside the guide sleeve 1. Its function is to facilitate the replacement of different models of connecting rods 13 and probes 15 by sliding the connecting rod 13 inside the guide sleeve 1.

[0025] Furthermore, the first chute 2 is a semi-circular groove, the slider 3 is semi-cylindrical in shape, and both the first chute 2 and the slider 3 are in two groups. The connecting plate 4 is plate-shaped and slidably connected inside the guide sleeve 1. Its function is to make the connecting plate 4 slide inside the guide sleeve 1 by sliding the slider 3 inside the first chute 2, and at the same time, make the sliding of the connecting plate 4 more stable.

[0026] Furthermore, both the first conductive tube 5 and the second conductive tube 6 are rod-shaped, and a part of the inside of the second conductive tube 6 is hollow. The first conductive tube 5 is slidably connected inside the second conductive tube 6. Its function is to make the first conductive tube 5 contact the second conductive tube 6 by sliding the first conductive tube 5 inside the second conductive tube 6, thereby facilitating conduction.

[0027] Furthermore, the spring 8 is in a spiral shape and is fixedly connected between the connecting plate 4 and the bottom plate 7. An insulating rubber layer is wrapped around the spring 8. Its function is that when the connecting plate 4 slides downward, under the elastic action of the spring 8, the connection between the connecting plate 4 and the connecting rod 13 becomes tighter and more stable.

[0028] Furthermore, the connecting column 9 is in a cylindrical shape, and the connecting groove 14 is a cylindrical groove. The connecting groove 14 is adapted to the connecting column 9. Its function is that by inserting the connecting column 9 into the inner side of the connecting groove 14, the connecting plate 4 is brought into contact with the connecting rod 13, thus facilitating conduction of electricity. At the same time, it also facilitates the installation of the connecting rod 13 and the probe 15.

[0029] Furthermore, both the second chute 10 and the fixing groove 11 are in a semi-circular groove shape, and both the second chute 10 and the fixing groove 11 are adapted to the slide bar 12. Its function is that when installing the connecting rod 13, by aligning the slide bars 12 fixedly connected to both sides of the connecting rod 13 with the two groups of second chutes 10, the slide bars 12 slide inside the second chutes 10 until the connecting column 9 is inserted into the inner side of the connecting groove 14. Then, when continuing to slide downward, the first conductive tube 5 slides into the inner side of the second conductive tube 6, causing the slide bars 12 to disengage from the second chutes 10. Then, by rotating the connecting rod 13 by 90 degrees, the two groups of slide bars 12 are aligned with the two groups of fixing grooves 11, thereby releasing the control of the connecting rod 13 and allowing the slide bars 12 to slide upward into the inner side of the fixing grooves 11.

[0030] Working principle: A first chute 2 is provided inside the guide sleeve 1. A slider 3 is slidably connected to the inside of the first chute 2. A connecting plate 4 is fixedly connected to the outer surface of the slider 3. A first conductive tube 5 is fixedly connected to the lower surface of the connecting plate 4. A second conductive tube 6 is slidably connected to the lower surface of the first conductive tube 5. A bottom plate 7 is fixedly connected to the lower surface of the second conductive tube 6. A spring 8 is fixedly connected to the upper surface of the bottom plate 7. A connecting column 9 is fixedly connected to the upper surface of the connecting plate 4. A second chute 10 is provided at the upper end inside the guide sleeve 1. A fixing groove 11 is provided on one side of the inside of the guide sleeve 1 away from the second chute 10. A slide bar 12 is slidably connected to the inside of the fixing groove 11. A connecting rod 13 is fixedly connected to the outer surface of the slide bar 12. A connecting groove 14 is provided on the lower surface of the connecting rod 13. A probe 15 is fixedly connected to the upper surface of the connecting rod 13. By making the two slide bars 12 fixedly connected to the outer surface of the connecting rod 13 correspond to the two second chutes 10 respectively, the connecting rod 13 slides into the inside of the guide sleeve 1. When sliding until the connecting groove 14 provided on the lower surface of the connecting rod 13 is connected to the connecting column 9 fixedly connected to the upper surface of the connecting plate 4, the connecting rod 13 continues to slide downward to compress the spring 8 until the slider 3 slides to the bottom of the first chute 2. At this time, the slide bar 12 disengages from the second chute 10. After rotating the connecting rod 13 by 90 degrees, the slide bar 12 corresponds to the fixing groove 11 provided inside the guide sleeve 1, so that the slide bar 12 slides into the inside of the fixing groove 11, thereby fixedly connecting the connecting rod 13 to the inside of the guide sleeve 1. Due to the elastic action of the spring 8, the connection between the connecting rod 13 and the connecting plate 4 is made more tight and stable, so that different models of connecting rods 13 and probes 15 can be quickly replaced, facilitating the rapid detection of the precision and complex power connectors of new energy vehicles.

[0031] The connecting column 9 fixedly connected to the upper surface of the connecting plate 4 is connected to the connecting groove 14 provided on the lower surface of the connecting rod 13. Then, by moving the connecting plate 4 downward, the first conductive tube 5 slides into the inside of the second conductive tube 6, so that the first conductive tube 5 contacts the second conductive tube 6, thereby connecting the connecting plate 4, the first conductive tube 5, the second conductive tube 6 and the bottom plate 7, so that current is transmitted through the first conductive tube 5 and the second conductive tube 6, thus ensuring the conductivity and preventing the current from being transmitted through the spring 8 and affecting the detection accuracy.
