Workstation with height adjustable desk

A workstation, comprising:

• a front partition member having a first end and a second end opposite to the first end;
• a first wall member connected to the first end of the front partition member and a second wall member connected to the second end of the front partition member to enclose a workspace;
• a desk board provided in the workspace;
• a first lifting mechanism fixed to the first wall member and connected to the desk board;
• and
• a second lifting mechanism fixed to the second wall member and connected to the desk board;
• wherein the first lifting mechanism and the second lifting mechanism are moved to lift and lower the desk board;
• wherein the second lifting mechanism includes a second linkage set, a second gear member, a second rail, and a second movable member;
• the second rail is fixed to the second wall member;
• the second linkage set includes a main linkage and two support linkages, wherein each of the support linkages has an end pivoted on the main linkage;
• an end of one of the support linkages movably engages the second rail, and an end of the other one of the support linkages movably engages the second movable member;
• an end of the main linkage is connected to the second gear member, and an opposite end of the main linkage movably engages the second movable member;
• the second movable member is connected to the desk board, so that a movement of the second linkage set moves the second movable member to lift and lower the desk board.
