A stapler is designed in such a way that it can be used with power at the middle or work at the middle. Mostly it is used with power at the middle; in this case it is class 3. If the power is applied at the end it is class 2.
Because you move the upper part of it up and down.
It is a third class lever.
Third class
Yes, it is.
yes it is but only a lever. a wedge has at least one wedged side. as you can see a normal stapler does not.
Third class lever. Here power lies in between load and fulcrum.
The stapler has its top and bottom joined at the hinge. Pressure applied on the top forces it against the bottom as the staple is pushed out. There is no mechanical advantage as with similar devices, such as the nutcracker.
It is not. A stapler is a third class lever. Simply because the the effort is in the middle. The fulcrum is the screw that allows it to move, the resistance is the staple wire that needs to press, and the effort came from your hand that is pressing the stapler - which is in the middle.
Yes, it is.

It has a pivot point
A stapler is a compound machine. It is made up of a lever and a wedge.
No, because the fulcrum is not in the middle
A stapler. It has a wedge and a lever.
Wheelbarrows, nail clippers, nutcracker, stapler, can opener, etc.

Pull the spring loaded band out by the 2 looped ears and then remove the saddle that pushes the staples. Slide the staples in and place the saddle back inot the slide. Hook the band over the saddle and your are good to go.
some lever simple machines are a stapler, scissors are a lever and wedge, there is lever machines is a car.
