[0002] Petrochemical industry refers to the processing industry that uses oil and natural gas as raw materials to produce petroleum products and petrochemical products. Instruments are needed in petrochemical work, and the instruments need to be tested before use. In order to assist the instrument to be tested stably, a petrochemical instrument testing device is needed.

[0003] During use, traditional petrochemical instrument testing devices mostly place petrochemical instruments inside the testing device, and then use electric push rods to limit the instruments, and assist in testing the instruments stably. However, during use, the traditional devices are susceptible to the impact stress of the electric push rods, which can easily cause damage to the internal components of the instruments. On the other hand, traditional devices use motors to drive the instruments to rotate, and assist in testing the instruments stably. As a result, during the rotation of the instruments, position deviation is prone to occur, and it is difficult to be stably limited and tested after movement, which affects the stable use of the device.
