Zusammenfassung:	A linear actuator comprises a main shell, a tail cover, a reinforcing seat, a power module and a transmission module. The main shell comprises an inner space and an opening, the tail cover is detachably connected to the main shell, and the reinforcing base is arranged in the inner space and connected to the tail cover. The power module is arranged in the internal space and comprises a motor. The transmission module is arranged in the internal space and comprises a bearing element, a screw rod, a main gear and an elastic element. And the bearing element is arranged in the reinforcing seat. One end of the screw penetrates through the bearing element and protrudes out of the inner space from the opening of the shell. The main gear sleeves the screw and is driven by the motor to rotate. One end of the elastic element is connected to the main shell and surrounds the screw. And when the motor stops driving the screw rod to rotate, the inertia acting force on the screw rod is eliminated by the elastic force of the e
