secondly, fixing the top cover main body (31) and the shell (1), applying a pressing force to the top of the surface of the high-voltage resistor main body (4) through the cambered surface limiting plates (32), forming a V-shaped structure with a downward opening by the two laterally symmetrical cambered surface limiting plates (32), further limiting the high-voltage resistor main body (4), and tightly attaching the anti-skid layer (33) to the top of the surface of the high-voltage resistor main body (4), so that the high-voltage resistor main body (4) is not easy to move randomly and has good stability;
thirdly, the pressing device (34) moves downwards along with the cambered limiting plate (32), the cambered pressure plate (221) is pressed through the cambered pressure head (342), and rolling friction is adopted in combination with rolling of continuous downward movement after the balls (343) are contacted with the surface of the cambered pressure plate (221), so that friction is reduced, the cambered pressure plate (221) is pressed, the elastic air bag (223) is compressed at the moment, and the air inside the elastic air bag enters the expansion bag body (233), so that the supporting plate device (231) is elastically supported;
step four, the rubber protrusions (2312) which are uniformly distributed on the surface of the cambered surface supporting plate main body (2311) are contacted with the bottom of the high-voltage resistor main body (4), so that flexible support is realized, and meanwhile, under the elastic action of the cambered elastic pieces (232), the cambered surface supporting plate main body (2311) is elastically supported by combining the expanded expansion bag body (233), so that the high-voltage resistor main body (4) is buffered, damped and protected.
