本试验机专门试验插头引出线及电线之耐折强度。试法是将试样固定在夹具上，并加一定荷重，试验时夹具左右摆动，经一定次数后检视其断线率，或至全部断线无法通电时查看其总计摆动次数。本机能自动计数，试样弯折至断线无法通电时，并能自动停止操作。
this tester is specialized in testing the flexing endurance betweenpower cord and blades，and is capable of testing the flexibilityresistance of the cord itself。samples are to be secured in the jawsof the flexing apparatus，and cord is to hang vertically with theweight tied on the lower end of it。the rotating jaws are to beadjusted to rotate to the angle of 90 degree to each side of thecentered position。after a certain cycles is reached or untilspecimen is broken，detect the breakage ratio or calcuate the totalcycles。this machine is able to auto-count and auto-stop duringspecimen broken。
