5) continue to move lever downwards, stay cord continues to pull drag hook downwards, and drag hook moves down and drives door font support and upper insulation plate to move down, and the claw of drag hook stretches in the snap ring of elastic wire clamp, again move lever to draw high and continue to move down, drag hook continues to move down to be opened elastic wire clamp;
6) elastic wire clamp is snapped in wire, now slowly upwards move lever, the pulling force that elastic force due to elastomeric spring is greater than spring makes upper insulation plate and door font support first move up, after the claw of drag hook stretches out snap ring, spring pulls claw to make drag hook around door font holder pivots to support side, now takes off insulating bar;
7) insulation cylinder of another clamping device is inserted insulating bar upper end, and p-wire is inserted p-wire socket;
8) repeat 3) ~ 6) step, the clamping device in step 7 is installed on wire;
9) to be tested complete, maintainer lifts insulating bar makes elastic wire clamp be in wire place, and insulation cylinder inserts in insulating bar;
10) operating personnel presses the lever of insulating bar lower end, lever pulls stay cord to move down, the pulling force that elastic force due to elastomeric spring is greater than spring makes stay cord spring when moving down first be stretched and then makes drag hook be in vertical state around the cross bar rotation of door font support, continue to move lever downwards, stay cord continues to pull drag hook downwards, drag hook moves down and drives door font support and upper insulation plate to move down, the claw of drag hook stretches in the snap ring of elastic wire clamp, again move lever to draw high and continue to move down, drag hook continues to move down to be opened elastic wire clamp, take off clamping device.
