The elastic pushing piece (2) drives the movable piece (14) to slide towards the direction of the heart-shaped sliding groove (1) when sliding into the rebound bracket, the sliding part (17) limits sliding into the first limit sliding area (50) through elastic friction force when the movable piece (14) slides to a certain position, the sliding part (17) slides along the track of the first conversion position (51) when the first limit sliding area (50) slides to a certain position, and limits sliding onto the inclined guide area (52) through the cooperation of the elastic friction force and the pushing elastic piece (16), and finally slides into and stays in the heart-shaped stay area (53) through the inclined guide effect of the inclined guide area (52); wherein the elastic pushing piece (2) and the extending piece (3) are positioned and closed on the rebound bracket when the sliding part (17) stays in the heart-shaped stay area (53);
When the sliding part (17) stays in the heart-shaped stay area (53) and the elastic pushing piece (2) and the extending piece (3) slide relative to the rebound bracket in a pressing way, the sliding part (17) slides out of the heart-shaped stay area (53) and slides along the track of the second conversion bit (54) and slides to the second limit sliding area (55) in a limited way through the cooperation of elastic friction force and the pushing elastic piece (16); when the sliding part (17) slides to the second limit sliding area (55), the elastic pushing part (2) drives the extending part (3) to extend elastically through the pushing elastic part (16) and open outside the rebound bracket.
6. The adjustable energy storage rebound device of claim 1 wherein: the rebound bracket is also provided with a control circuit board (27), a power supply element (29) and a reset driving assembly (30) which are respectively and electrically connected with the control circuit board (27); the reset driving assembly (30) is in driving connection with the elastic pushing piece (2) and/or the extending piece (3); the control circuit board (27) acquires working power through the power supply element (29) and drives the reset driving assembly (30) to reciprocate on the rebound bracket;
When the extension piece (3) is elastically extended and opened for a certain time, the reset driving assembly (30) drives the elastic pushing piece (2) and/or the extension piece (3) to automatically reset and slide in through the control of the control circuit board (27) and is positioned and closed on the rebound bracket; the reset driving assembly (30) is reset to the initial position by the control of the control circuit board (27) when the elastic pushing piece (2) and/or the protruding piece (3) are/is closed.
