A push pin is a fastener. As a minimum, it fastens a very visible head to a surface. Even used symbolically on e.g. Google maps.
Alternately it may fasten one surface (paper) to another.
I would say a wedge.

it depends on the type of the pin
A Credit Card Pin is a 4 digit number that you can use in combination with your physical card, to access your bank account from an automated teller machine (ATM).

Grab a pin, a pendulum (weight on the end of a piece of string), a ruler and pencil. Push the pin through the object and attache the pendulum to the pin. Make sure that the irregular object hangs freely on the pin. Allow pendulum and object to settle. Carefully mark where the pendulum crosses the bottom edge of your object, then join that mark with the original hole using a ruler. If you repeat this experiment the lines should all cross at the cengre of gravity because that will always come to rest under the pin. This assumes that the flatness is uniform.

the type of machine that a clothes pin is, is a lever
A wedge because it wedges it's self through fabrics and other materials.

Moore worked at a photo lab and was missing a simple solution to hang up film to dry so he invented the push pin.
Pressure is inversely proportional to area. A sharp pin has lesser area compared to a blunt pin. Therefore we require lesser pressure to push the pin with lesser area.Hence it's easier to push a sharp pin which has lesser area.
The safety pin has a pin that goes into the head of the pin, and you push the point in or out of the head of the pin.

A "regular" rolling pin is a wheel and axle. The "wheel" here is the broad surface of the roller, and the handles are on the ends of the axle.
