Equip animation but part of the body stays somewhere?

Hey,

I try making a game where the player has a camera in his hands. Now I´d like to add an animation when the player “activates” the camera. I already have the HUD etc. prepared. I also created an animation where the hand moves towards the head.

Now I want the hand to stay where the head is, as if he´s holding the camera infront of his eyes and is watching through.
I don´t know how to fix that the hand is always going to its original place after playing the animation. I can´t figure out how to make it stay fixed to the head.

I´d love if anyone could help me.
