Adjustable board support for easel

An easel board support installed to an easel supporting leg for suspending and supporting objects, the height of easel board support being adjustable;

• characterized in that:
• 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;
• a receiving groove is formed between the two pivotal ears;
• a cambered pressing block is installed in the receiving groove;
• another end of the board support body has a pivotal seat with an axial hole;
• a surface of the pivotal seat facing the sleeve and a top surface of the pivotal seat have respective first and second protrusions;
• a lower side of the protrusion on the surface of the pivotal seat has a resisting block;
• thereby, when the two pivotal ears are pivotally installed to the pivotal seat and the first protrusion and the board support body are horizontally arranged;
• the first protrusion resists against the press of the sleeve so that the press resists against the easel supporting leg;
• by a large contact surface between the pressing block and the supporting leg, the board support is positioned stably;
• and by the resisting effect between the resisting block and an outer wall of the sleeve, the board support will not fall downwards so as to increase the supporting strength;
• the receiving groove and the cambered concave surface are formed with a positioning block and a positioning trench, respectively, which are conformed to one another so as to prevent the pressing block from falling into the sleeve in assembly.
