A support device includes a base, a bracket for supporting an object, and an arm and a lever pivotally secured between the base and the bracket for forming a parallelogrammic structure. The arm is pivotally secured to the base with a shaft. The lever is secured to the base with a rod and has a curved groove for slidably receiving the shaft. The lever has an orifice for loosely receiving the rod. The base has a stop for engaging and latching the lever to the base, without additional fasteners, when the lever is elevated relative to the base. |
