     Several definitions that apply throughout this disclosure will now be presented. 
     The term “coupled” is defined as connected, whether directly or indirectly through intervening components, and is not necessarily limited to physical connections. The connection can be such that the objects are permanently connected or releasably connected. The term “substantially” is defined to be essentially conforming to the particular dimension, shape, or other feature that the term modifies, such that the component need not be exact. For example, “substantially cylindrical” means that the object resembles a cylinder, but can have one or more deviations from a true cylinder. The term “comprising,” when utilized, means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in the so-described combination, group, series and the like.

The first segment  42  of the linking assembly  40  is fixed in the groove  362  and the second segment  44  pivots on the first connecting pillar  122  or on the second connecting pillar  222 . The linking assembly  40  links the first fixing member  10  and the second fixing member  20  together, across the third fixing member  30  and the assembly is thus complete. 
     When the first fixing member  10  is rotated, the second segment  44  connected with the first fixing member  10  rotates relative to the first fixing member  10 , one of the two first segments  42  slides in the groove  362  of the flake  36 , the linking gear  3822  is driven by the teeth portion  422  to rotate to drive another of the two first segments  42  to slide in the groove  362 . The second segment  44  connected with the second fixing member  20  is driven to rotate the second fixing member  20 . When the first fixing member  10  is rotated, the linking assembly  40  drives the second fixing member  20  to rotate. When the second fixing member  20  is rotated, the linking assembly  40  drives the first fixing member  10  to rotate (referring to the  FIG. 9 ). 
     Although the features and elements of the present disclosure are described as embodiments in particular combinations, each feature or element can be used alone or in other various combinations within the principles of the present disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
