σ [Prior Art] When the test item of simple blood type test or blood glucose measurement is used, it is not necessary to use a syringe to extract venous blood, and a lancet with a needle tip is used. Very inconvenient, the rotation of the wrist makes the blood collection needle penetrate the road to be taken, and it is impossible to pierce the fingertip. Therefore, some people have designed a pen to make the needle penetrate the fingertips of the person to be collected. The needle can be repeatedly pressed to make the needle stick out. Therefore, it is possible to replace the new needle without directly replacing the new needle. Dangerously, some biological sensors need only a small amount of blood. Therefore, a small amount of blood-collecting person should take a fingertip at the early fingertips. Therefore, a little bit of liquid can be used for examination. The force-like blood collection device is only convenient for taking blood. However, if the blood collection personnel do not use the needle, it needs to be improved. It is necessary to use this kind of blood collection to pay attention to the second use. [Invention content] The invention can be reused after being used once, in order to improve the conventional use, the present invention provides a method of pressing again, and the new needle holder must be reassembled. Safety blood collection device. In order to achieve the above object, the present invention provides a safety blood collection device, wherein the 1246911 comprises a housing group, an actuation group assembled in the housing, and a needle holder assembled in the housing group via a seat motion control, wherein: the actuation group The utility model comprises a fixing seat, a pressing seat, a control component, a pushing component and a second elastic component; wherein the fixing seat has a tubular shape and an inner diameter conforms to the outer diameter of the needle seat, and a circle is formed inwardly at the middle section The block has an open channel on the wall at the upper edge of the block, and the 4-pin seat group is inserted into the lower end of the fixed seat.
