[0085] On both side walls of the rear drive slider 5, there is a rear protruding end 5.2 each. The drive sliding sleeve 15 is installed on the rear protruding end 5.2 of the shaft and slides in the lower chute of the slide rail by a distance d. The rear drive slider 5 is automatically centered in the slide rail through the two rear protruding ends 5.2.

[0086] On the drive flexible shaft plastic package part 4, there are two rotating shaft structures which are clamped with the front drive slider 3 and the rear drive slider 5. The front drive slider 3 and the rear drive slider 5 can rotate on the drive flexible shaft plastic package part. The drive flexible shaft plastic package part 4 is driven by a motor, thereby driving the front drive slider 3 and the rear drive slider 5 to move.

[0087] As Figure 18 shown, the front lifting arm shaft - the second front fulcrum 2.2, the first front fulcrum 2.1, the third front fulcrum 2.3, the front drive slider 3 and the turning chute 9 form a self-locking device. When the motor drives the drive flexible shaft plastic package part 4 to slide backward, the drive flexible shaft plastic package part 4 drives the front drive slider 3 and the rear drive slider 5 to slide backward. The third front fulcrum 2.3 will gradually move downward along the chute track 18 of the front drive slider, and the first front fulcrum 2.1 will rotate upward along the turning chute track line 19 with the second front fulcrum 2.2 as the center. When the motor is not running, the front drive slider 3 is pulled by the drive flexible shaft plastic package part 4 and remains stationary. Then the third front fulcrum 2.3 cannot move downward, and the first front fulcrum 2.1 cannot rotate upward with the second front fulcrum 2.2 as the center. The front lifting arm 2 cannot lift, and the movable glass is pulled by the front lifting arm 2 and will not move.
