[0024] When it is necessary to close the two elevator door panels 10 to the passage slot 3, the self-locking motor 4 is started so that its output end drives the transmission rod 6 to rotate in the transmission slot 5, so that the two No. 1 gears 7 rotate and respectively engage to drive the No. 2 gear 8 to rotate, and the two No. 2 gears 8 respectively drive the two bidirectional threaded rods 9 to rotate in the slide slot 2. At this time, the two elevator door panels 10 threadedly sleeved on the two bidirectional threaded rods 9 move relatively along the threads of the two bidirectional threaded rods 9 under the rotation of the two bidirectional threaded rods 9. The multiple rolling wheels 15 arranged under the two elevator door panels 10 slide synchronously in the slide slot 2 and assist the movement of the two elevator door panels 10 in the slide slot 2. At this time, the relative movement of the two elevator door panels 10 in the slide slot 2 is achieved when only one self-locking motor 4 is used, and the use and maintenance costs are lower;
