5) if the handle (402) is positioned in the first positioning pin hole of the working position '1 bit' or '0 bit' of the second dial (403), the situation that the latch hook of the unlocking mechanism to be tested is not released or the release angle is not satisfactory occurs, the handle (402) is slowly rotated to find the standard release position of the latch hook, the handle (402) is fixed at the position by using a first locking bolt (406), the corresponding angle of the rocker arm on the second dial (403) is read by a scale reading part (407) on the handle (402), then the angle difference value between the angle and the standard false locking position '1 bit' and the standard unlocking position '0 bit' is calculated, and then the size of the related connecting rod in the unlocking mechanism product to be tested is adjusted according to the corresponding relation of the angle.
