Purtroppo non ho trovato nessuna traduzione in Italiano, ma leggendo le istruzioni di alcuni siti in Inglese dove si parla di chiodatrici, sono giunto alla conclusione che si tratta della molla che serve alla chiodatrice per tirare e portare in posizione il chiodo (spostando in alto la striscia di chiodi) seguente a quello che viene sparato.
Di seguito alcuni link dove si parla di come caricare la pistola sparachiodi o chiodatrice.

For load and draw models, once you insert the fasteners into the base of the magazine, you will pull the pusher back until the nail follower drops behind the end of the nail strip. Let go of the pusher, and the follower will push the nail strip up into the base of the driving mechanism, loading your tool.

How to Load a Best Electric Nail Gun?
First, consider whether you can feed nails from top or bottom of a magazine. You can judge whether a nail is top- or bottom-loading by looking at the point of nail exit, and finding a release button. The location of the latter is usually opposite of the nozzle.

Second, ensure you’ve the right size or head type of nails. Third, switch off power supply, and ensure that the nozzle faces away from you. For a top loading nail gun, lock a magazine follower into position by pulling it back.

Then, place nail strips over a rail so that there’s free movement of the nails. Lastly, unlock and release the follower to push nails toward the nozzle.
