[0055] In this embodiment, the conversion of voltage is realized through the cooperation of the above circuit elements.

[0056] The utility model discloses a working principle is as follows: when the connecting port 3 on the shell 1 is connected with the connecting port on the connecting line, the connecting port on the connecting line is screwed, the connecting port on the connecting line is gradually screwed with the connecting port 3 gradually, and the connecting port of connecting line gradually enters the inside of the protection pipe 4, the clamping rod 7 contacts the outside of the connecting port of connecting line at this time, and the friction between the clamping rod 7 and the connecting port on the connecting line is increased through the effect of the non-slip mat on the clamping rod 7, so as to reduce the probability of the connecting port of connecting line rotating relative to the connecting port 3 due to jolt;
