Abstract
The present disclosure illustrates a fastening device including a sleeve, a rotary knob device and a drive cap. The sleeve is formed with a through-hole which defines a rotation space at a side thereof. A fastening part and a position-limiting ring are formed on an outer side of the sleeve, and the position-limiting ring includes multiple position-limiting fastening grooves on a periphery thereof. The rotary knob device includes a rotary rod movably inserted through the through-hole. The assembly space of the sleeve is formed with a sliding inner hole for covering the position-limiting ring of the sleeve, and the position-limiting ring is longitudinally movable in the sliding inner hole, and the sliding inner hole includes two long protrusion rods and two short protrusion rods formed on the sidewall thereof and separately fastened in the position-limiting fastening grooves. Therefore, the fastening device can be operated for locking or unlocking easily.
