When the moving plate 4 moves, it will drive the driving member to move downward together, and then drive the torque sensor 8 and the plug-in module 9 to move downward together, so that the plug-in module 9 is inserted into the automotive clock spring. By the work of the driving member, the torque sensor 8 and the plug-in module 9 are driven to rotate together, and then the torque and angle of the automotive clock spring are tested. After the torque and angle tests are completed, the release and clamping step is carried out, and the fixture drives the automotive clock spring to rotate to the lower position.
