The invention discloses a gear shifting speed reducer for an electric container lifting appliance and the electric container lifting appliance. The gear shifting speed reducer comprises a motor, a gear shifting mechanism and a speed reducer, the gear shifting mechanism comprises a supporting box body, a connecting sleeve, a planetary speed reducing mechanism and a shifting fork assembly. The supporting box body comprises an upper shell, a lower shell and a fixed gear ring; the connecting sleeve is connected with a motor output shaft of the motor, and an outer tooth surface and an inner tooth surface are arranged on the connecting sleeve; the planetary reducing mechanism comprises a sun gear, a planet gear and a planet carrier; the planet gear is connected with the sun gear and the fixed gear ring through a tooth surface on the planet gear; the shifting fork assembly drives the connecting sleeve to slide up and down along the output shaft of the motor, and switching of a high-speed gear and a low-speed gear of the gear shifting speed reducer is achieved. The speed reducer is connected with a planet carrier of the planet speed reducing mechanism. The high-speed gear and the low-speed gear can be switched through the gear shifting mechanism, so that the problem of matching of driving force and speed between single-box stretching and double-box translation is solved.
