Support stand for flat-panel display monitor and elevating support used for support stand

An elevating support, used for a support stand of a flat-panel display monitor, the elevating support comprising:

• a first link bracket comprising a first end portion and a second end portion;
• a second link bracket comprising a first end portion and a second end portion;
• a connecting piece rotatably connecting the first end portions of the first and the second link brackets;
• and
• a supporting block rotatably connecting the second end portions of the first and the second link brackets;
• wherein the first link bracket forms a first limiting protrusion on the first end portion, and a second limiting protrusion on the second end portion;
• the connecting piece forms a restricting flange;
• the supporting block forms a restricting pole;
• the first limiting protrusion of the first link bracket abuts the restricting flange and the second limiting protrusion of the first link bracket abuts the restricting pole, thus adjusting the elevating support to move between a first utmost position and a second utmost position.

A support stand for a flat-panel display monitor, comprising:

• a rotatable bracket;
• a hinge assembly comprising a connecting piece, and a pivotal shaft inserted through the connecting piece and the rotatable bracket;
• a base member comprising a supporting block;
• a first link bracket comprising a first end portion and a second end portion;
• and
• a second link bracket comprising a first end portion and a second end portion, the first end portions of the first and the second link brackets rotatably connecting to the connecting piece, the second end portions of the first and the second link brackets rotatably connecting to the supporting block;
• wherein the first link bracket forms a first limiting protrusion on the first end portion, and a second limiting protrusion on the second end portion;
• the second link bracket defines a first limiting groove in the first end portion, and a second limiting groove in the second end portion;
• the pivotal shaft forms a restricting flange;
• the supporting block forms a restricting pole;
• when the support stand is in a first utmost position, the second limiting protrusion abuts the restricting pole, and the first limiting groove abuts the restricting flange;
• when the support stand is in a second utmost position, the first limiting protrusion abuts the restricting flange, and the second limiting groove abuts the restricting pole.
