Abstract
An assembled-type fastener unit includes a base, a handling member movably fitted in the base, and a locking device movably received in the handling member. The handling member can be operated for the locking device to extend out of the base to form a locked state or for the locking device to retract into the base to form an unlocked state. To use the fastener unit, the base is firstly connected to an object. Then, the handling member is operated for the locking device to extend out of the base and lock to a target object to form the locked state; or the handling member can be operated for the locking device to retract into the base to separate from a target object and form the unlocked state. Thus, at least two objects can be repeatedly and quickly connected to or disconnected from one another using the fastener unit.
