The internal rotation of the second adjustment hole is connected to the second adjustment member 14, and the second adjustment member 14 is used in conjunction with the connecting seat 1.

[0025] As a technical optimization solution of the present invention, by setting the first adjusting member 13 and the second adjusting member 14, the positions of the first adjusting member 13 and the second adjusting member 14 can be controlled so that they can respectively press against the rotating seat 7 and the connecting seat 1, thereby achieving the adjustment of the gap and shaking amount during the folding process.

[0026] refer to Figure 7 The connecting seat 1 and the supporting member 2 are manufactured as one piece.

[0027] As a technical optimization solution of the present invention, the setting in which the connecting seat 1 and the support member 2 are manufactured as one body reduces the complexity of the production of the connecting seat 1 and the support member 2 and the probability of more failures, and the appearance looks simple and clear.

[0028] refer to Figure 5 and Figure 6 The top of the position-limiting clamping member 10 is in the form of a barb, and the top of the position-limiting clamping member 10 is in a clamping connection with the rotating seat 7 .

[0029] As a technical optimization solution of the present invention, the top of the limiting clamping member 10 is set as a barb, which can clamp and position the rotating seat 7, thereby preventing it from rotating independently and achieving a secondary protection effect.
