Patent ID: 8456822

Claim:
A support assembly, comprising: a base comprising at least one sliding rail; a slidable member able to slide along the at least one sliding rail of the base, wherein the slidable member defines a pair of blind holes facing the base; a pair of positioning shafts mounted on the base to slide along in a direction perpendicular to the at least one sliding rail, wherein when the slidable member is caused to slide along the at least one sliding rail of the base, one of the positioning shafts can be pressed to slide to cause one end of the one of the positioning shafts to be received in one of the blind holes; an operational member and a pair of clasps, wherein the operational member is movably mounted on the base, the clasps are secured to the base, each of the clasps comprises two elastic sidewalls with two ends that abut each other, one end of each of the positioning shafts passes through one of the clasps, when the operational member is pressed to cause one end of the operational member to be clasped by one of the clasps, the one end of the operational member presses one end of the positioning shaft passing through the one of the clasps, causing an opposite end of the positioning shaft to be received in one of the blind holes; and a pair of second elastic portions being placed over one end of each of the positioning shafts, wherein when one end of one of the positioning shafts is received in one of the blind holes, the second elastic portion placed over the one of the positioning shafts is compressed, and when the end of the one of the positioning shafts moves out of the one of the blind holes, the second elastic portion rebounds.
