The invention discloses a disposable safe blood collection anti-acupuncture device, which includes a protective shell, including a first accommodating cavity formed by pressing the first upper shell and the head end of the lower shell, and the second upper shell and the second upper shell. The second accommodating cavity formed by pressing the tail end of the lower case; the needle holder is movable in the first accommodating cavity formed by the protective shell, the needle holder is a hollow tubular structure, the needle The inner wall of the seat axially passes through the blood collection needle, and the blood collection needle protrudes from the needle seat towards the tail end of the lower housing and enters the second accommodating cavity, and the first accommodating cavity and the second accommodating cavity The distance between the accommodating cavities is smaller than the length of the needle holder; wherein, the inner wall of the first accommodating cavity is provided with a card platform, and the outer wall of the needle holder is provided with a rib matching the card platform, and the blood collection is completed. Finally, the needle seat drives the blood collection needle to move from the second accommodating cavity to the first accommodating cavity, and when the convex rib passes through the card table, the blood collection needle completely enters the in the second accommodating cavity.
