In this embodiment, the rotary electricity taking mechanism 136 includes a power supply disc 1361, a rotating frame 1362, a second end cover, a first spring 1363, a first positive plate 1364, and a plurality of second positive plates 1365, a plurality of negative plates 1366, and a plurality of ground plates 1367 that are all distributed in a circumferential array;
