Professional Office Basic Style Desktop Paper Stapler

The working principle of an ordinary stapler is that when the hand presses the stapler end cover hard, the thimble, needle, and clip will rotate around the connector pin. As the manpower force continues to be applied, the top will rotate out of its natural state. At this point, the top will move up and down around the connecting pin slightly more than a needle height, the spring compression of the end cover, and the compression of the shrapnel, which will then drive the downward movement of the needle. After a certain distance of movement, the needle will come into contact with the object that needs to be bound and pass through the object under the action of manpower. The needle will touch the mold and the needle will bend after passing through the object, so as to achieve penetrating binding between the needle and the object.
After the binding is completed, the person removes the force on the end cover of the needle. At this time, the shrapnel bounces back. The needle, clip, top, and end cover will rebound under the action of elasticity, and then the end cover spring bounces back. The top and end cover rebound again. The top is detached from the clamp; The expansion of the push spring allows the needle to be given again, so that the stapler returns to its initial state and waits for binding again.
