Adjust the height of the goal by pulling the pull plate (48) toward the side surface away from the movable chamber (43), so that the pull plate (48) drives the slider (44) to slide in the movable chamber (43) through the insertion rod (45), and the insertion rod (45) slides out of the slot (46) and slides into the movable chamber (43). At the same time, the slider (44) continuously presses the spring (47) toward the inner wall of the movable chamber (43), so that the spring (47) is compressed and deformed, and then the connecting rod (42) is slid in the guide groove (41) to make the connecting rod (42) slide in the movable chamber (43). The connecting rod (42) drives the sleeve (51) and the slide bar (52) to rise, and when the sleeve (51) and the slide bar (52) are moved to a suitable height, the pull plate (48) is released, and the slide bar (44) is pushed to slide in the movable bin (43) by the restoring force generated by the spring (47) being squeezed by the slide bar (44), and the slide bar (44) is synchronously driven by the insertion rod (45) to slide into another group of slots (46), so that the height of the goal can be adjusted. When it is necessary to adjust again, the above steps can be operated in the same way; S2. To adjust the width of the goal, the positioning groove (57) is rotated to make the positioning groove (57) drive the gear (55) to rotate in the fixed plate (54), and the gear (55) acts on the rack (53) synchronously, so that the rack (53) drives the slide bar (52) to slide in the sleeve (51), and when the width of the football is adjusted to a suitable width by the slide bar (52) sliding in the sleeve (51), the connecting plate (59) is screwed with the threaded rod (58), and the positioning rod (510) on the connecting plate (59) is aligned with the positioning groove (57), and then the pull plate (48) is loosened, and the restoring force of the spring (47) is used to synchronously drive the positioning rod (510) through the threaded rod (58) to insert into any group of positioning grooves (57) on the brake disc (56), so as to achieve the purpose of adjusting the width of the goal. When it is necessary to adjust again, the above steps are operated in the same way.
