A box door 5 is hinged on the front of the explosion-proof box 2, and a window 6 is installed on the box door 5. A high-voltage tester 7 is installed on the top of the explosion-proof box 2. A terminal 8 is installed on the high-voltage tester 7. The terminal 8 is inserted into the interior of the explosion-proof box 2. A fire-fighting mechanism 9 is installed on the outer wall of the explosion-proof box 2. The fire-fighting mechanism 9 includes a fixing frame 91 fixed on the outer wall of the explosion-proof box 2, and a fire extinguisher 92 is installed inside the fixing frame 91. An adapter 93 is installed on the side of the fire extinguisher 92. The adapter 93 is inserted into the interior of the explosion-proof box 2 and is connected to a nozzle 94.

[0020] When in use, the vehicle power supply is placed in the fixed seat 31 in the support mechanism 3, and then the adjusting rod 33 is rotated to make it rotate. The adjusting rod 33 drives the slider 35 to slide in the slide groove 32 through the threaded transmission with the threaded sleeve 34. Since the threads at both ends of the adjusting rod 33 have opposite rotation directions, the two sliders 35 drive the support plates 36 to approach each other, and the support plates 36 are used to clamp the vehicle power supply to improve the stability during the test. Then, the terminal 8 on the high-voltage tester 7 is connected to the positive and negative poles of the vehicle power supply through the wire, and then the box door 5 is closed to start the high voltage.

During the test, the first fan 43 and the second fan 44 are started, and the first fan 43 introduces external cold air into the explosion-proof box 2, and the second fan 44 draws out the hot air in the explosion-proof box 2, which can avoid overheating of the vehicle-mounted power supply during the test. When a dangerous situation occurs during the test, the fire extinguisher 92 sprays the fire extinguishing agent into the explosion-proof box 2 through the adapter 93 and the nozzle 94, which can control the dangerous situation in time.
