The invention relates to a novel propulsion interlocking mechanism for a low-pressure draw-out type drawer. The novel propulsion interlocking mechanism comprises an operation interlocking mechanism, an operation locking structure unit, an electric operating auxiliary joint structure unit, a position control auxiliary joint structure unit, a tri-position display structure unit, a rotary propulsion structure unit and a rotary propulsion interlocking structure unit. The novel propulsion interlocking mechanism has the characteristics that the operation locking structure unit with the structure is simple, can be completely matched with a common hand mechanism, and is consistent in assembly mode, operation mode and position display; and the troubles in production and use of a low-pressure cabinet body are eliminated.
