The slot block 11 is provided with a connecting rod 3 inside, and the surface of the connecting rod 3 is embedded in the empty groove opened on the surface of the slot block 11. A thread groove is opened on the top surface of the connecting rod 3, and a thread is opened on the inner wall of the thread block 32. The thread of the inner wall of the thread block 32 is engaged with the thread groove opened on the top surface of the connecting rod 3, and the bottom of the connecting rod 3 is rotatably connected to the inner walls on both sides of the groove opened on the surface of the fixed plate 2. The top of the connecting rod 3 is fixedly connected with a limit block 31, and the limit block 31 prevents the thread block 32 from being separated from the surface of the connecting rod 3.

[0026] In this embodiment, the threaded block 32 of the slot block 11 is made of metal material. When the threaded block 32 rotates downward along the thread on the surface of the connecting rod 3, the threaded block 32 presses against the top surface of the slot block 11 to apply downward pressure to the slot block 11, which will not easily cause the connecting rod 3 to escape from the empty groove opened on the surface of the slot block 11, and can fully ensure that the slot block 11 is tightly clamped between the threaded block 32 and the fixed plate 2.

[0027] Example 2

[0028] like Figure 1-Figure 4 As shown, a water tank 4 is fixedly connected to the surface of the fixed bracket 12. The water tank 4 is located at the top inside the shell 1 and fixed on the fixed bracket 12. The water tank 4 is used to store pure water of the system for use in electrolyzing water to produce hydrogen by the electrolyzer 7. The pressure relief valve 5 is used for overpressure protection to prevent the device from being damaged due to excessive pressure. The water level sensor 6 is used to sense the water level in the water tank 4. The water pump 8 is located below the water tank 4 and is used for increasing the flow and stabilizing the pressure of the water supplied to the water inlet of the electrolyzer 7. The electrolyzer 7 is located on the right side of the water pump 8 below the water tank 4 and is fixed on the fixed bracket 12. It produces hydrogen and oxygen by electrolyzing water. The transformer 9 is located below the water tank 4 and is fixedly mounted on the other side of the fixed bracket 12.

[0029] In this embodiment, the water tank 4 has a trapezoidal shape, which improves the water storage capacity inside the water tank 4. At the same time, the water tank 4 is equipped with a pressure relief valve 5 and a water level sensor 6.

If the water level is too low, a signal will be output to the transformer 9, and the transformer 9 will emit a buzzer prompt sound. The input voltage is the automobile power supply voltage fixed bracket 12V / fixed plate 2 water tank 4V DC, the output voltage is the working voltage of the device, which controls the voltage and current output of the entire system and provides a start signal for the water level sensor 6.
