[0034] In operation, first, the torsion plate 66 is twisted to drive the screw rod 64 to rotate inside the one-side adjusting slot 61. The screw rod 64 is threadedly connected with the one-side sliding block 62, so that the one-side sliding block 62 drives the connecting rod 7 and the rotating rod 4 to move inside the rotating slot 2 through the rotating sleeve 5, thereby adjusting the connection between the abutting plate 3 and the end of the long rod 101 and the short rod 102, and making the toothless gear 10 disengage from the fixed seat 8, so that the abutting plate 3 is disconnected from the end of the supporting rod 1.
