The output shaft of the drive motor 16 is connected to the middle part of the guide plate 12.

[0027] like Figures 4 to 6As shown, the sliding locking assembly 2 includes a slider 21, a guide rail 22, a moving member 23, a locking member 24, a return spring 25, a telescopic spring 26, a cam 27 and a locking motor 28.
