The clamping unit includes a base, a plurality of arc-shaped clamping members, an elastic ring, and a shaft cover. The base is fixed in the receiving space. The base has a circular cavity. The circular cavity is provided with a plurality of elongated grooves. The arc-shaped clamping members each have a first axle to slide in a corresponding one of the elongated grooves and a second axle. A center of the arc-shaped clamping members is formed with an adjustable clamping opening. The shaft cover is formed with a plurality of axle grooves arranged annularly. The second axles of the arc-shaped clamping members are pivotally connected to the respective axle grooves. The quick-release unit has a shaft. After the shaft passes through the adjustable clamping opening, the adjustable clamping opening subjected to the elastic force of the elastic ring is retracted to clamp the shaft.
