摘要：
An administration assembly is presented having a plunger rod, a first resilient member biasing the plunger rod, an elongated plunger rod holder configured to receive the plunger rod, an activation sleeve receiving a portion of the plunger rod holder, and configured to move axially from a first position relative to the plunger rod holder to a second position. The activation sleeve is biased towards the first position and the plunger rod holder has a first hold and release structure and the plunger rod has a second hold and release structure, wherein in the first position the activation sleeve is configured to maintain the first hold and release structure in an axially locking contact position with the second hold and release structure in which the second hold and release structure is prevented from movement relative to the first hold and release structure, thereby locking the plunger rod axially relative to the plunger rod holder.
