The mounting frame 2 is installed on the left side above the vehicle body 1, and a bidirectional threaded rod 8 is installed on the middle position inside the mounting frame 2. The bidirectional threaded rod 8 is rotatably connected to the mounting frame 2. A sliding rod 9 is installed on the left side of the bidirectional threaded rod 8, and an upper contact plate 10 is installed on the upper position of the right side of the bidirectional threaded rod 8. A conductive rod 11 is symmetrically arranged on the lower position of the upper contact plate 10. The conductive rod 11 and the upper contact plate 10 are connected to the bidirectional threaded rod 8 through a transmission nut. The conductive rod 11 and the upper contact plate 10 are connected to the bidirectional threaded rod 8 through a transmission nut. They are all connected to the sliding rod 9. A high-voltage generator 3 is installed on the right side of the mounting frame 2. A connecting sleeve 4 is installed on the lower right side of the high-voltage generator 3. A connecting block 14 is installed inside the connecting sleeve 4. The connecting block 14 is slidably connected to the connecting sleeve 4. A contact block 15 is installed on the right side of the connecting block 14. A test box 5 is installed on the right side of the high-voltage generator 3. A contact sleeve 12 is installed on the lower left side of the test box 5. A rebound plate 16 is installed in the middle position inside the contact sleeve 12. A connecting rod 18 is installed on the right side of the rebound plate 16. The connecting rod 18 is connected to the electromagnet 20 inside the contact sleeve 12.

[0021] A second spring 17 is arranged between the rebound plate 16 and the contact sleeve 12, a hole is opened in the middle position of the rebound plate 16, the position of the hole above the rebound plate 16 corresponds to the installation position of the contact terminal 19 inside the contact sleeve 12, the installation position of the contact sleeve 12 corresponds to the installation position of the connecting sleeve 4, a first spring 13 is arranged between the connecting block 14 and the contact sleeve 12, the test box 5 is slidingly connected to the vehicle body 1, an electric cylinder 21 is installed on the vehicle body 1 below the test box 5, the electric cylinder 21 is connected to the test box 5, a grounding sleeve 6 is installed on the vehicle body 1 below the conductive rod 11, a grounding rod 22 is arranged in the grounding sleeve 6, a third spring 23 is arranged between the grounding rod 22 and the grounding sleeve 6, a motor 7 is installed at the upper position of the mounting frame 2, and the output shaft of the motor 7 is connected to the bidirectional threaded rod 8 through a coupling.

[0022] Working principle: When in use, the grounding rod 22 is connected to the high-voltage generator 3 through a wire, and then the electric cylinder 21 drives the test box 5 to move toward the side of the high-voltage generator 3, and the connecting sleeve 4 is then inserted into the contact sleeve 12, and the contact block 15 contacts the contact terminal 19, and the motor 7 drives the bidirectional threaded rod 8 to rotate. While the bidirectional threaded rod 8 rotates, the upper contact plate 10 and the guide rod move toward each other, and the conductive rod 11 moves downward and contacts the grounding rod. The third spring 23 is compressed, and the grounding rod contacts the ground, and then the test product is placed in the test box 5 for testing. When an accident occurs during the test, the electromagnet 20 loses power, and the second spring 17 drives the rebound plate 16 to move toward the side of the connecting sleeve 4, and the rebound plate 16 pushes the contact block 15, and the contact block 15 drives the connecting block 14 away from the contact. One side of the terminal 19 moves, and the first spring 13 is compressed, thereby achieving power off. When discharge is required, the motor 7 drives the bidirectional threaded rod 8 to move in the opposite direction, and the bidirectional threaded rod 8 drives the upper contact plate 10 and the conductive rod 11 to move towards each other, and the conductive rod 11 contacts the upper contact plate 10, and the upper contact plate 10 contacts the high-voltage generator 3, thereby achieving discharge. In this process, the connecting sleeve 4, the contact sleeve 12, the first spring 13, the second spring 17, the rebound plate 16 and the electromagnet 20 cooperate with each other, so that the device can be powered off in the event of a fault or an emergency, thereby increasing the safety of the device. Moreover, the mounting frame 2, the bidirectional threaded rod 8, the upper contact plate 10 and the conductive rod 11 are used in conjunction with each other, thereby increasing the automation level of the device, so that the device can achieve automatic power off.
