The invention discloses a six-gear control mechanism suitable for an automobile-direct-control-manner manual transmission. The six-gear control mechanism comprises the manual transmission and a gear shifting lever matched with the manual transmission. The gear shifting lever is characterized in that an upper control rod is connected with a lower control rod through a damping rubber sleeve. The peripheral face of the damping rubber sleeve and the peripheral face of the upper control rod are sleeved with a sliding sleeve, positioning pins for preventing rotation are arranged between the sliding sleeve and the damping rubber sleeve, the upper portion of the upper control rod is sleeved with a limiting gasket, and the portion, located below the limiting gasket, of the upper control rod is sleeved with a pulling return spring. A limiting support is connected to a transmission control cover of the manual transmission through a positioning bolt. The positioning bolt is sleeved with a sector-shaped limiting plate and a belleville spring. A limiting block is arranged on the upper control rod. An adjustment bolt is arranged on the limiting support. The six-gear control mechanism has the beneficial effects of being simple and compact in structure and capable of being conveniently arranged in a cab.
