[0002] The impeller of a washing machine is an important rotating component in the washing machine, usually made of plastic or metal. Its main function is to help wash clothes. It generates water flow and friction through high-speed rotation, so that the clothes can be fully stirred and cleaned in the water. During the production and processing of the impeller, in order to ensure the balance of the impeller when it rotates at high speed, an impeller balance tester is needed to perform rotational balance test on the produced impeller workpiece. When installing and testing the impeller workpiece on the impeller balance tester, a testing tool is needed.

During the high-speed rotation test, if the impeller workpiece is of poor quality and breaks and flies out, it may easily cause harm to external personnel. The use safety is insufficient and it is not convenient to perform safety protection to prevent the impeller workpiece from flying out during the test.

[0004] Now, a novel washing machine impeller balance detection tool is proposed to solve the above-mentioned shortcomings. Utility Model Content
