[0034] A specific application of this embodiment is as follows: first, when the center net 2 needs to be replaced, the staff member toggles the toggle plate 46 fixed on the circumferential surface of the sleeve 45 to apply force to the sleeve 45, driving the torsion spring rod 44 rotating on the inner wall of the concave block 43 to rotate, thereby rotating the sleeve 45 and driving the contact plate 47 fixed on the circumferential surface of the sleeve 45 to make an arc movement. When the contact plate 47 makes an arc movement, it no longer contacts the fixing plate 42 fixed on one end of the fixing rod 41. Then the staff member pulls the center net 2 to the rear side, thereby driving the fixing plate 42 to rotate. The sliding plate 34 on the front side slides in the slide groove 33 provided on the rear side of the connecting plate 32. When the middle net 2 moves, it drives the groove 35 provided on the front side to move, thereby contacting the limit block 38 sliding inside, so that the spring 39 fixed at one end of the sliding rod 37 is forced to shrink, and at the same time drives the sliding rod 37 to slide into the interior of the hollow rod 36. Finally, when the sliding rod 37 slides, it drives the limit block 38 to move and no longer contacts the inner wall of the groove 35. At the same time, when the middle net 2 moves, it drives the sliding plate 34 to separate from the inner wall of the slide groove 33.
