Abstract
A supporting frame includes at least one supporting element, a base and a light-permeable pillar. The supporting element has a first through-hole. A cam is disposed in the supporting element and has a second through-hole and a turning portion. The second through-hole is disposed corresponding to the first through-hole. The base extends to form a sleeve. The light-permeable pillar passes through the first through-hole and the second through-hole and is inserted into the sleeve. The supporting element is capable of sliding along the light-permeable pillar. The turning portion is configured for pushing against an inner wall of the supporting element for fixing the supporting element on the light-permeable pillar.
