Benefits of technology

"The present invention is a drawing pin that automatically draws back to its original position when moved. This solves problems that arise when trying to securely hold items in place. The pin has a containing portion and a pin portion that can be extended from the containing portion. The containing portion provides a resilient force that allows the pin portion to automatically move back to its original position when the pin portion is moved. This invention provides a more convenient and secure way to hold items in place."

Problems solved by technology

The feelings that the skin touched by the pins when users take out drawing pins to be used from the box or take down them from a billboard and put them on the palm are very unpleasant.
When the drawing pins drop on the ground, they will incur dangers if a person passed by steps on it inadvertently.
In addition, the way of receiving the drawing pins was not desirable, since the drawing pins will be always scattered in the box disorderly, leading to great inconvenience when taking drawing pins.
