5. The damped rebounder of claim 1, wherein, The driving part on the anti-rebound trigger movable element is a straightly arranged rack, and the anti-reversing driving shaft is provided with a gear matched with the rack on the anti-rebound trigger movable element.

6. The damped rebounder of claim 1, wherein, A sliding track changing mechanism is arranged between the rebound pusher and the shell, and comprises a sliding groove and a circular sliding block arranged on the rebound pusher and matched with the sliding groove, wherein the sliding groove comprises an arc segment arranged at the front end of the shell and a horizontal segment arranged at the rear end of the shell, the arc segment is curved upward, and the horizontal segment extends linearly along the length direction of the shell; when the circular sliding block in the rebound pusher enters the arc segment, the rebound pusher rotates upward, so that the drawer can be pulled out of the hook groove of the rebound pusher; when the circular sliding block in the rebound pusher enters the horizontal segment, the rebound pusher rotates downward, so that the hook groove of the rebound pusher hooks the drawer.

7. The damped rebounder of claim 1, wherein, The side of the locking block opposite to the locking groove is also provided with a groove of the same structure as the locking groove.

8. The damped rebounder of claim 7, wherein, A limiting groove is further arranged on the trigger block, and the limiting groove is arranged outside the first locking part; when the trigger mechanism is triggered, the locking block enters the limiting groove, so as to limit the angle of reverse rotation of the reverse driving shaft.

9. A functional drawer comprising the press-synchronous pop-up and soft-close damping rebounder according to any one of claims 1-8.
