When the frame 21 is subjected to an upward tension, as... Figure 9 As shown, when the rotating block 23 contacts the top side of the abutment hole 101, it can rotate, so that the rotating block 23 can flip from the lower abutment hole 101 to the upper abutment hole 101. After the rotating block 23 flips into the upper abutment hole 101, the tension of the tension spring 25 will also cause the rotating block 23 to quickly return to its original position, preventing the rotating block 23 from sliding from the upper abutment hole 101 to the lower abutment hole 101.
