ABSTRACT:
A type of angle/height adjusting device for electronic organ stand, comprising a leg stand and a position adjusting device, the leg stand being composed of two tubes of I-shaped legs that are hinged in their middle parts to form an "X" configuration, so the cross rods on top of the leg stand will support an electronic organ; characterized in that: the position adjusting device is composed of a control rod, a spring and two positioning discs; the control rod is fitted inside the upright tube of one of the I-shaped legs, with a handle bar and a positioning block protruding out of the top part and lower part of the upright rod, and the spring is fitted between the top part of the control rod above the handle bar and the cross rod on the I-shaped leg, the two positioning discs are respectively fixed at the joint of the two I-shaped legs. Thus, the positioning block below the control rod will be accommodated in the vent on the positioning disc, to fix the two I-shaped legs; in order to adjust the angle and/or height of the entire stand, the handle bar is grasped to lift the control rod, so the positioning block is disengaged from the vent on the positioning disc, so the positioning block is accommodated in another vent on the positioning disc, thus the objective of adjusting the height of the leg stand can be accomplished.
