The present invention provides a support frame. The support frame comprises: a housing (10) having a plurality of rotation grooves (12); an operational module (50) installed on the housing (10) and rotated by an operating force; legs (20) inserted into the rotation grooves (12) and provided with rotary units (22) installed and rotated on the housing (10); an upper fixing member (60) which is installed on the housing (10), receives the operating force from the operational module (50) to be moved downwards, and produces mutual friction with the rotary units (22); and a lower fixing member (70) which is installed on the housing (10), receives the operating force from the operational module (50) to be moved upwards, and produces mutual friction with the rotary units (22). A high strength friction member (61) is arranged on at least one among the rotary units (22) and the housing (10) producing mutual friction to form a frictional force when coming in contact with each other. The support frame in accordance with the present invention can provide a constant frictional force at all times even if used repeatedly since the high strength friction member is tightly attached to the rotary units. |
