The control board fixing base 8 is fixedly installed on the epoxy resin insulating board 5 by a hexagonal isolation copper pillar 7. The adjusting base 4 isolates the epoxy resin insulating board 5 and the control board fixing base 8 into an independent space, so that the lithium battery 6 is prevented from contacting moisture.

[0024] Specifically, the adjusting base 4 includes a base plate 41 that is fixedly connected to the baffle 24. The base plate 41 is hollow at both ends. A lower cylinder 42 that is fixed to the vertical cylinder side 23 is provided at the bottom of the base plate 41.
