US Patent 7330349 Docking apparatus

A docking apparatus includes a port replicator (50), a base (30) for supporting the port replicator thereon, a fixing member (60), a resilient member (80), and a button (10). An accommodating hole (51) is defined in the port replicator, and a hole (351) is defined in the base corresponding to the accommodating hole of the port replicator. In use, the resilient member drives the fixing member upwardly to extend through the hole of the protrusion to engage in the accommodating hole of the port replicator thereby fixedly attaching the port replicator to the base. The button 10 is to drive the fixing member to retract from the accommodating hole of the port replicator to release the port replicator from the base.
