When folding the diverting needle body 403, first drag the rubber ring 404 at the outer end of the lightning protection ball 402 upward, then the rubber ring 404 will tighten the diverting needle body 403, then the spring 405 will press down to retract the diverting needle body 403, then rotate the connecting rod 401 and place it in the inner end of the card slot 304, and after closing the cover plate 307, the folding of the diverting needle body 403 can be realized.

[0033] By dragging the rubber ring 404, pressing down the spring 405, and rotating the connecting rod 401 and other steps, the folding of the shunt needle body 403 can be achieved, and the operation is simple and convenient. In this way, the shunt needle 4 can be easily retracted, saving time and labor costs.
