The adjusting device comprises an operating rod fixed to the object to be adjusted; a rope; and a movable plate pivotally connected to the connector. The pull end and the pressure applied end of the movable plate are not at the same line. It is only necessary to rotate the operating rod, the rope will be pulled to drive the pressure applied end of the movable plate to touch a touch moving end of the movable plate of the air pressure rod, causing the air pressure rod to move telescopically to drive the object to move upwards or downwards so as to adjust the position of the object. |
