En Yo-Yo Tester

The yo-yo ball rope extension test instrument makes the length measuring system( to calculate the elongation length) and the yo-yo ball is installed in the same spindle for rotating. When the yo-yo ball rotates at the speed of 80r/min, the line of the ball will stretch along the centrifugal direction, and the test line(one end fixed in the ball, the other end fixed on the trolling reel) is connected with the encoder, the trolling reel and the spindle of the encoder are free states, and the bearing friction can be ignored.
