Abstract: A support mechanism includes a bracket and a rotary unit including a base and at least one adjustment subassembly. The adjustment subassembly includes an elastic member and a ball. The elastic member resists the ball to contact the bracket. The bracket is rotatable relative to the base.

Abstract: An adjustment module includes a frame, a sliding member, at least one coiled spring, a pair of guide rails, and a supporting member. The frame includes a main plate. The at least one coiled spring includes an extending portion and a sleeved coiled portion. The guide rails are positioned on opposite sides of the frame. The supporting member is fixed on the frame and has at least one supporting surface. The sliding member is slidably positioned between the guide rails. The coiled portion of the at least one coiled spring is positioned on the at least one supporting surface. An end of the extending portion of the at least one coiled spring is fixed on the sliding member, and an axis of the coiled portion of the at least one coiled spring is substantially perpendicular to the main plate.

Abstract: A hinge assembly includes a base, a joint member, a pintle, and a coiling spring. The joint member is rotatably connected to the base. The pintle runs through the base and the joint member. The coiling spring has a first end and a second end. The first end is fixed relative to the base, and the second end is fixed relative to the joint member.

Abstract: A hinge assembly includes a pivot shaft, a rotary member and a steady member sleeved on the pivot shaft. The rotary member and the steady member faces each other and are rotatable relative to each other. The rotary member forms a first peak, and the steady member forms a second peak. A friction portion is formed between the rotary member and the steady member. A thickness of the friction portion exceeds or equals to a thickness of either of the first peak or the second peak, and is less than the combined thickness of the first peak and the second peak. A support mechanism using the hinge assembly is also provided.

Abstract: An adjustable mechanism includes a first bottom plate, a second bottom plate, a receiving block positioned, a receiving block, and an elastic member. The receiving block is positioned between the first bottom plate and the second bottom plate. The receiving block defines a receiving cavity. The connecting member includes an inserted portion. The inserted portion defines a latching groove therein. The elastic member includes an elastic protrusion. The inserted portion and the elastic member are received in the receiving cavity in such manner that the elastic protrusion is received in the latching groove.
