摘要： An angle adjusting assembly of a stand tube comprises a stand tube having a front end; a penetrating unit passing through the front end; a rear end of the stand tube being formed with a combining portion; an ejection device including a screw rod; a top of the screw rod having an ejection block; a quick-detaching unit having a driving unit and a positioning control unit; the positioning control unit being interacted with the ejection block of the ejection device; and a front forked unit having a pivoted shaft which can be pivotally installed to the combining portion of the stand tube. When the ejection block is driven by the driving unit to move upwards and downwards, the elastic unit below the ejection block will compress the limiting element. Thus the angle between the front forked unit and the stand tube is adjustable.
