本机专门测试插头引线及电机之耐折强度
试验标准：符合；UL-817标准
试验方法：将试料固定在夹具上，并加一定荷重，试验时夹具左右推动，经一定次数
后，检视其断线率；或至无法通电时，查看其总计推动次数。本机能自动计数，试料弯折至
无法通电时，并自动停止工作。
This machine is specially used to test the anti-folding intensity of the plug leading wire and the
electrical machine。
Test standard：meets the standard of UL-817。
Test Method：fixing the test material in the jig and plusing a certain load。When doing the test，
promotes the jig from the left to the right。After a certain number of times，examine its
disconnection rate；or in the failure of electricity，examine its total number of impetus。
This machine can count automatically and automatically stop working in the condition of
the specimen bend and in the failure of electricity。
