[0002] The transmission is a mechanism used to change the speed and torque from the engine. It can fix or change the transmission ratio of the output shaft and the input shaft in stages. The transmission consists of a speed transmission mechanism and an operating mechanism. Some cars also have a power output mechanism.

[0003] When the transmission is assembled, the gears will be installed in the transmission. When the gears are assembled, the transmission needs to be positioned. The transmission will be placed on a base, and then the transmission will be clamped from both sides through limit plates. The gears will be installed in the transmission. When the limit plates limit the transmission, the transmission cannot be in a suspended state. This requires manual flipping of the gears during assembly, which increases the operator's workload. The specifications of the transmission make it inconvenient to flip it, which in turn affects the efficiency of transmission assembly. Utility Model Content
