As utility model further sets up to: the connecting piece is in a strip shape, one surface of the connecting piece is concave along the length direction, and the other surface of the connecting piece is convex relative to the concave surface.

As utility model further sets up to: the connecting piece is a rubber strip, and the initial length of the rubber strip is not more than the length from the tail end of the needle seat to the top end of the needle head.

As utility model further sets up to: the acupuncture part is cylindrical.

As utility model further sets up to: the metal groove is formed in the acupuncture part corresponding to the top end of the needle head, and anti-falling objects for preventing the needle head from being separated from the metal groove are filled in the metal groove.

As utility model further sets up to: the anti-dropping object is rubber.

As utility model further sets up to: the outer surface of the handle is provided with anti-skid grains.

As utility model further sets up to: the anti-skid lines are arranged in a cross shape.

Compared with the prior art, the utility model discloses following profitable technological effect has:

1. after the blood taking needle is used up, the needle puncturing part is pulled to puncture the needle into rubber in the metal groove, then the blood taking needle is thrown away, after blood taking, the needle is not easy to puncture medical workers or other personnel, the subsequent treatment of the blood taking needle is more convenient, and the safety of the blood taking needle is improved.

2. The connecting piece is rolled on the needle base, so that the operation of medical staff is not easily hindered when the blood taking needle is used.

3. After the needle head penetrates into the rubber in the metal groove, the needle head can be bent under the rolling force action of the connecting piece, so that the used blood taking needle is prevented from being recycled by some lawless persons, and the blood taking needle is recycled or sold.
