Adjustable board support for easel

The present invention relates to board supports, and particularly to a easel board support, wherein by a large contact surface between the press piece and the supporting leg, the board support is positioned stably; and by the resisting effect between a resisting block and the sleeve, the board support will not fall downwards. An easel board support is installed on an easel supporting leg for suspending and supporting objects and the height thereof is adjustable. The easel board support comprises a sleeve and a board support body. The sleeve is capable of being inserted by an easel supporting leg and have two pivotal ears each having through hole. A part of the sleeve at an inner side of the pivotal ear has a slot. An elastic press is formed between the two slots. By a large contact surface between the press piece and the supporting leg, the board support is positioned stably; and by the resisting effect between a resisting block and the sleeve, the board support will not fall downwards. The press can be replaced by a receiving groove formed between the two pivotal ears and a cambered pressing block installed in the receiving groove.
