The invention discloses a double-worm-gear gear shifting execution mechanism for a mechanical automatic gearbox. The mechanism is characterized by comprising a first-gear and second-gear gear shiftingmechanism and a third-gear and fourth-gear gear shifting mechanism. The first-gear and second-gear gear shifting mechanism comprises a first worm rod, a first worm wheel, a first poking finger and afirst turning sensor, wherein the first worm rod is driven by a first motor; the first worm wheel is in key connection with a first transmission shaft; the first worm wheel and the first worm rod forma worm-gear transmission pair; the first poking finger is in pin connection to the first transmission shaft; and the first turning sensor is mounted at the end part of the first transmission shaft. The third-gear and fourth-gear gear shifting mechanism comprises a second worm rod, a second worm wheel, a second poking finger and a second turning sensor, wherein the second worm rod is driven by a second motor; the second wor
