In the field of chemical tests, stirring bars are one of the basic test tools for long-term use. In the chemical test process, the stability of the stirring rod largely determines whether the test can be successfully performed. Many chemical tests require a relatively fast stirrer speed due to the long reaction time. However, during the test, problems of stirring rod instability occurred. The stirring rod falls off and stops rotating in the high-speed rotation process, so that the test fails, and even the reaction explosion can cause irreversible serious consequences such as injury to operators. Meanwhile, stirring bars of different sizes are often required to be used according to the test contents. The stirring rod is a vulnerable article, and the stirring rods with different sizes use the same-size connecting device, so that not only can the tool storage space be saved, but also the cost can be reduced and the resources can be saved.
