Snippet from Wikipedia: Hammer (firearms)

The hammer is a part of a firearm that is used to strike the percussion cap/primer, or a separate firing pin, to ignite the propellant and fire the projectile. It is so called due to the fact that it resembles a hammer in both form and function. The hammer itself is a metal piece that forcefully rotates about a pivot point.

The hammer of a firearm was given its name for both resemblance and functional similarity to the common tool. The function of the hammer is to strike the firing pin in a firearm, which in turn detonates the impact-sensitive cartridge primer.

When the trigger of a firearm is depressed, it acts on the sear, which in turn releases the spring-tensioned hammer. Some firearms have a striker instead of a hammer and firing pin.
