A cover 2 is movably connected to the top of the housing 1 via a hinge. A push plate 3 is fixedly connected to the bottom of the cover 2. The cover 2 can seal the housing 1 and can also limit the fault detector body 13 by driving a clamping plate 8 through the push plate 3. Isolation plates 4 are fixedly connected to both sides of the inner wall of the housing 1. A distance is provided between the isolation plate 4 and the ejector plate 12 to facilitate the movement of the ejector plate 12 driven by the spring 11. A limit rod 5 is provided inside the isolation plate 4. Slide plates 6 are slidably connected to both sides of the limit rod 5. A connecting plate 7 is fixedly connected to one side of the slide plate 6, and a clamping plate 8 is fixedly connected to one side of the connecting plate 7. The clamping plate 8 can limit the movement of the fault detector body 13, preventing it from shaking inside the housing 1 when placed for carrying. A wedge 9 is fixedly connected to the other side of the connecting plate 7. Both sides of the limit rod 5 are fitted with… A tension spring 10 is provided, with its two ends fixedly connected to one side of the inner wall of the housing 1 and one side of the slide plate 6, respectively. A spring 11 is fixedly connected to the bottom of the inner cavity of the housing 1, and a push plate 12 is fixedly connected to the top of the spring 11. The push plate 12 can push the fault detector body 13 to the removal position, thereby facilitating the user to remove and use it. The fault detector body 13 is set on the top of the push plate 3. A charging slot 23 is opened on one side of the inner wall of the housing 1. A fixing plate 14 is fixedly connected to the inner wall of the housing 1, and a rotating rod 1 is rotatably connected to one side of the fixing plate 14. 5. A sealing plate 16 is fixedly connected to the surface of the rotating rod 15. A sealing ring 17 is fixedly connected to one side of the sealing plate 16. The sealing plate 16 and the sealing ring 17 can seal the charging slot 23 to prevent external dust or water from entering the interior of the box 1. A first magnetic absorbing piece 18 is fixedly connected to the bottom of one side of the sealing plate 16. A second magnetic absorbing piece 19 is provided on one side of the inner wall of the box 1. The first magnetic absorbing piece 18 and the second magnetic absorbing piece 19 are neodymium iron boron permanent magnets, and the first magnetic absorbing piece 18 and the second magnetic absorbing piece 19 are connected to each other magnetically.

[0028] Example 2

[0029] Please see Figures 1-5Based on embodiment 1, a placement groove 20 is provided on one side of the inner wall of the box 1. The second magnetic absorbing piece 19 is fixedly connected to the inside of the placement groove 20. The placement groove 20 can fix the second magnetic absorbing piece 19. A sliding groove is provided on one side of the isolation plate 4. The sliding groove can facilitate the movement of the connecting plate 7. The connecting plate 7 is slidably connected to the inside of the sliding groove. A limiting plate 24 is fixedly connected to one side of the box cover 2. The limiting plate 24 is used to push the fault detector body 13 to move. The limiting plate 24 can move the fault detector body 13 into the box 1. And with the spring 11 and the ejector plate 12, the fault detector body 13 can be ejected when the box cover 2 is opened, so as to facilitate the user to take it out for use. A sealing groove 21 is provided on one side of the inner wall of the box 1. One side of the sealing ring 17 extends into the sealing groove 21. A handle 22 is fixedly connected to one side of the box cover 2. The handle 22 is used to drive the fault detector body 13 to move. The clamping plate 8 is made of silicone rubber, which can reduce some of the impact force while fixing the portable fault detector.

[0030] The working principle of this utility model is as follows: When the fault detector body 13 needs to be used, the user first opens the box cover 2 by using the handle 22. The box cover 2 will drive the push plate 3 to move, thereby releasing the limit on the inclined block 9. Then, the tension spring 10 will drive the slide plate 6 to move through its own elasticity. The slide plate 6 drives the clamping plate 8 to move through the connecting plate 7, thereby releasing the limit on the fault detector body 13. The opening of the box cover 2 will also drive the limit plate 24 to move. Then, the spring 11 at the bottom of the box 1 will push the ejector plate 12 to move through its own elasticity. The ejector plate 12 will raise the fault detector body 13 to a height that is easy to access, and the user can easily take out the equipment for testing.

[0031] After the test is completed, the device is placed back on the ejector plate 12. When the case cover 2 is closed, the case cover 2 will drive the push plate 3 and the limit plate 24 to move. The limit plate 24 presses down on the fault detector body 13 to reset it. The push plate 3 will squeeze the inclined block 9. The inclined block 9 will drive the connecting plate 7 to move. The connecting plate 7 will drive the clamping plate 8 to move, thereby limiting the fault detector body 13 to prevent it from shaking during carrying.

[0032] During charging, the user inserts the charging head directly into the charging slot 23. When the charging head contacts the sealing plate 16, the charging head pushes the sealing plate 16 to rotate, and moves the first magnetic piece 18 and the sealing ring 17, thus facilitating subsequent charging. When the charging head is removed, the sealing plate 16 closes due to its own gravity. When the lid 2 closes, it moves the first magnetic piece 18 and the sealing ring 17, causing the first magnetic piece 18 and the second magnetic piece 19 to attract each other again. At the same time, the sealing ring 17 moves into the sealing slot 21, thus sealing the charging slot 23 and preventing dust, moisture, etc. from entering the charging slot 23. This effectively protects the charging interface, extends the service life of the fault detector body 13, and ensures that the charging function is always stable and reliable.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
