Abstract

The invention relates to a pushpin safe to use. The pushpin safe to use comprises a pushpin cap and a needle body. The tail portion of the needle body is connected with the pushpin cap, the pushpin cap is provided with a deformation cover which is made of soft materials and formed at one end of the needle body, the deformation cover is provided with a cavity, one end of the cavity is opened, the needle body is located in the cavity, and a needle point faces the cavity to be opened. The soft deformation cover with a groove is adopted to automatically wrap the needle body to prevent the needle body from pricking people, meanwhile the deformation cover automatically separates to expose the needle body as long as the needle body is pressed to a fixing face when the pushpin safe to use is used, and the pushpin safe to use is convenient to use.

Description

technical field [0001] The invention relates to an office product, in particular to a safety thumbtack. Background technique [0002] At present, most pushpins on the market are straight pushpins, including nail pins and nail caps, which are used to attach paper or other items to objects. Straight pushpins are convenient to use. When users want to use pushpins to fix Things are easy to puncture and easy to take out when things are on the wall or bulletin board, but this kind of thumbtack is easy to fall off during use, and the thumbtack falls on the ground and it may not be easy to be found, but it will cause harm to the human body inadvertently. [0003] For example, Chinese patent publication CN 102862432 A relates to an anti-pricking thumbtack, including a nail cap, a nail needle and a sheath, the nail cap is a columnar structure, and the nail needle is fixed at the center of the bottom of the nail cap; The sheath is a sleeve-like structure, and its inner section corresp...
