[0011] Furthermore, a hinge slot is formed through the engaging portion between the first fixing clamping plate and the second fixing clamping plate, and a hinge bolt rod is installed in the hinge slot.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The present application can limit the two connecting rods by the limiting hinged fixing member through the cooperation between the first fixed clamp plate, the second fixed clamp plate, the first clamp block, the second clamp block, the limiting clamp head and the fixing bolt, without the need to limit the position through the combination between the connecting rods, so that the two connecting rods will not slip between them, thereby reducing the wear of the connecting accessories and increasing the service life.
