At least two link units each have a fixing plate, a first link and a second link. Each of the fixing plates has two first holes defined in two ends thereof, each of the first links has two second holes defined in two ends thereof, and each of the second links has two third holes defined in two ends thereof. A pin extends through the overlapped first, second and third holes. The at least two link units are connected to two sides of the side plates of the base. Another pin extends through the first hole in one of two ends of each of the fixing plates and the adjustment hole of each of the side plates. Yet another pin extends through the overlapped first, second and third holes and the curved slot of each of the side plates. A clamp unit has a guiding member, two pivotal holes and two through holes. A pin extends through the pivotal holes and the third holes of two respective free ends of the second links. A support unit has a bar, a positioning part and a support frame. The bar has a fixing hole. The positioning part has two pivotal holes on two sides thereof and the two pivotal holes are located corresponding to the through hole of the clamp unit and the fixing holes of the base. A pin extends through the fixing holes, the through holes and the pivotal holes. A pin extends through the fixing hole of the bar and the second holes of two respective free ends of the first links. |
