Overview
Usage
This tester is used to test fatigue of the reciprocating rod for the l age. During the test, the rod would be stretched and then test whether there will be backlash, loose, connecting problems and transformation of the rod.
Theory
Under certain pulling and pressing frequency, To check the reciprocating fatigue performance of the pull rod, rod structure of fastness and durability of the switch through the l age lever lock with a pull rod is continuously pulling switch, reciprocating and pressing.



III.Design Criteria

Design criteria: QB/T 2919-2007。




IV.Equipment Instruction
