The synchronizer finishes the one-time gear shifting process, after gear shifting is finished, the integrated hydraulic actuator moves leftwards to drive the sliding gear sleeve 9 to move leftwards, the sliding gear sleeve 9 drives the swing pin spring device to swing leftwards, and when the left end face of the swing pin 13 is in contact with the right end m face of the large disc of the gear hub positioning pressure plate 10, the swing pin 13 cannot pop up due to the fact that the sliding gear sleeve 9 moves leftwards to influence the next circulating normal gear shifting of the synchronizer.
