Adjusting apparatus for release member

Abstract

An adjusting apparatus includes a driver, a drive shaft attached to the driver, an adjusting wheel, and a clipping member. The clipping member is engaged with the adjusting wheel. The adjusting wheel and the clipping member are configured to clamp a release member together. The adjusting wheel relative to the drive shaft has a first position and a second position. When the adjusting wheel is in the first position, the adjusting wheel is engaged with the drive shaft. The drive shaft with the clipping member and the release member are rotated by the driver together. When the adjusting wheel is in the second position, the adjusting wheel disengages from the drive shaft and is rotatable relative to the drive shaft rotating the release member. The release member is configured to push out merchandise.
