Example two:
the applicant finds in practice that when the movable rod 10 is pulled by the operating handle 16 to drive the clamping plate 7 to move and adjust to a proper position, the clamping pin 12 moves downwards to be clamped into the clamping groove 11, so that the movable rod 10 is fixed, and then the motor to be tested is fixed. However, inevitably, a gap exists between the bayonet 12 and the bayonet 11, and the existence of the gap may cause the clamping plate 7 to be unable to complete the clamping of the motor or the clamping effect is limited. On the other hand, there is a gap between the movable shaft 9 and the movable rod 10, which also results in poor clamping effect for the tested motor, and although the fixing spring 14 is designed in the first embodiment to overcome this defect, the practical effect is limited.
