Yo-yo is a technical sport in hand which is popular around the world. In a nation, yo-yo due to quality light, flexibility, the parents always think that is educational toys, but they don’t know, there are hidden safety hazards inside.

According to the statistics, asphyxiation caused by yo-yo always happened around age 3-6, so it’s important to the physical and mechanical safety inspection of children's toys.
Yo-yo tester is used to test the yo-yo Initial length and elastic constants, including steel ruler, measuring and scale, weights, the length test system (used to calculate the elongation length), and the yo-yo are mounted in many places and rotated on the same spindle.
The instruments accord the standard of ASTM F963, adopt intelligent micro controller control, encoder and intelligent control signal transmission system, high measurement accuracy, simple operation, high level of automation.
