Dig the earth, push the handle, and then the head will arise with dig sands. The point is an added stick at the body frame; a support fixture. With this little change, which does not affects the whole manufacture process of normal spades, the seesaw spade is able to use the principle of the lever, transferring pushing down power with the gravity to the pulling up power at the head of the seesaw spade, having more power to lift the spade up, making people be able to lift more sands with less power and easier action; just pushing down.
