A push pin is a type of inclined plane, where the sharp end acts as the wedge. By applying force to the head of the pin, the sharp end easily penetrates into surfaces.
A board pin is a type of fastener and can be considered a type of simple machine known as a wedge. The pointed end of the pin helps it exert force to push materials apart, making it easier to fasten objects together.
A pin is classified as a type of fastener and not a simple machine. It is often used to secure two materials together.
Edwin Moore invented the push pin in 1900 as a way to securely attach papers together without causing damage. The design of the push pin allowed it to easily pierce through paper and hold it in place, making it a convenient alternative to traditional pins or clips.
A clothespin is considered a double lever simple machine. It consists of two rods (levers) hinged together to grip an object when squeezed.
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.

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.
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.
