While the bidirectional threaded rod 6 is rotating, the first clamping bracket 7 and the second clamping bracket 8 can be adjusted using the sliding rod 5, thereby fixing the connecting mechanism 2 to the frame 1. This method is applicable to the mechanical installation of frames 1 of different specifications, improving practicality. After the connecting mechanism 2 is fixed, hold the first handle 16 and rotate it to drive the first threaded shaft 15 from the first sleeve. Adjusting the first threaded shaft 15 from the second sleeve 18, the first pressure plate 17 can be adjusted to fit tightly against the connecting mechanism 2. Holding the second handle 20 and rotating it will cause the second threaded shaft 19 to be adjusted out of the second sleeve 18. The second pressure plate 21 can be adjusted to fit tightly against the connecting mechanism 2. The cooperation of the first pressure plate 17 and the second pressure plate 21 can achieve the purpose of fixing.
