[0059] When it is not necessary to loosen the fixing component 4, the paddle 43 rotates by a certain angle on the bolt 42, so that the paddle 43 fits against the rocker arm 24, reducing the volume of the rocker arm 24; when it is necessary to loosen the fixing component 4, by pulling the notch 431, the paddle 43 rotates 90° on the bolt 42, and the rotation of the paddle 43 drives the bolt 42 to rotate, so that the cooperation between the bolt 42 and the nut 41 is loosened, enabling the sliding plate 32 to slide away from the first jaw 31 in the installation groove 25. The first limit block 321 disengages from the first limit groove 311, and the first coil spring 313 pulls the first jaw 31 to rotate 90° and unfold. The second limit block 332 disengages from the second limit groove 312, and the second coil spring 331 pulls the second jaw 33 to rotate 90° and unfold. The unfolded first jaw 31 and the unfolded second jaw 33 are parallel to each other.
