Abstract
The invention provides a safety needle component which structurally comprises a needle base, an injection needle and an anti-stabbing safety device for preventing a needle head of the injection needle from being exposed. The needle base is provided with a liquid inlet cavity. A needle tail of the injection needle is fixed to the needle base and communicated with the liquid inlet cavity. The position, close to the needle head, of the injection needle is provided with a limiting groove. The anti-stabbing safety device is connected to the injection needle in a sleeving mode so that the injection needle can move on the anti-stabbing safety device. The anti-stabbing safety device comprises a sleeve and an elastic limiting piece, wherein the elastic limiting piece is fixed in the sleeve and used for being clamped in the limiting groove. When the injection needle finishes the injection work, the needle base is pulled to drive the injection needle to move, and the elastic limiting piece is clamped in the limiting groove, so that the needle head of the injection needle is contained in the sleeve, and problems existing in the prior art are solved. When the injection needle finished injection, the needle head of the injection needle is contained by the anti-stabbing safety device and prevented from being exposed, and the function of preventing the injection needle from stabbing the human body is achieved.
