[0002] With the development of the automobile industry, new technologies and processes for automobile parts are changing with each passing day. The replacement of automobile air-conditioning parts products is also getting faster and faster, and the requirements for their performance and quality are also getting higher and higher. Automobile air-conditioning parts generally include air-conditioning HVAC, condensers, compressors, operating mechanisms and pipelines, etc. Among them, automobile air-conditioning HVAC is composed of a heating system, a refrigeration system, a fan, an air circulation duct, a conversion control device for the air outlet mode, and a circulation control system for the internal and external air. The above-mentioned control and adjustment is completed by controlling the adjustment mode conversion actuator. The mode actuator must rotate the valve plate of the corresponding control and adjustment HVAC air circulation to a specified angle under a certain ventilation resistance.

[0003] Therefore, the torque and rotation angle values ​​output by the output shaft of the actuator are directly related to the effectiveness and accuracy of the control and adjustment of various functional modes of the air conditioner HVAC. A Chinese patent (Announcement No.: CN 207730429U) discloses a mode conversion actuator tester for an automobile air conditioner HVAC. By comparing the actual rotation angle of the actuator to be inspected with the actual rotation angle of the angle pointer in real time, the detection result of the actuator to be inspected can be obtained. The result is more intuitive and clear through comparison. However, in the above document, the actuator to be inspected is placed on the part to be inspected for inspection, and there is no structure on the part to be inspected to clamp and fix the actuator to be inspected, which results in the actuator being easily falling off when the actuator to be inspected is placed on the part to be inspected for inspection.

[0025] In addition, two fixing holes 411 are provided on opposite sides of the two anti-slip plates 43, and the cross bar 42 is located on the inner side of the fixing hole 411 and fixed thereto, so that the cross bar 42 can be fixed inside the anti-slip plate 43, making it convenient for the threaded rod 44 to be connected to the inner cavity wall of the cross bar 42, so that when the threaded rod 44 rotates, the cross bar 42 can move on the outer surface of the threaded rod 44.

[0026] Furthermore, the crossbar 42 is in the shape of a hollow cylinder, and the opposite sides of the left and right sets of crossbars 42 are both missing, so that the threaded rod 44 can move into or out of the interior of the crossbar 42 .
