[0002] PE pipes are a common type of pipe, often used in home renovation and infrastructure construction. After each batch of PE pipe fittings is produced, sampling inspection is required to ensure that the pipe fittings leaving the factory meet quality requirements. The inspection methods include pressure resistance test and bending test. The bending test is often carried out by the operator bending the PE pipe until a predetermined angle is reached to observe whether the pipe fitting breaks. This method has poor accuracy and high labor intensity for the operator. Therefore, it is particularly necessary to develop a pipe fitting bending test device that can save manpower and has high accuracy. Summary of the Invention
