The related a kind of injection needle tube for having needle tip protection cap of this creation system a comprising cylinder, a push element, a needle body and a needle tip security component. Cylinder has a cylinder first end and a cylinder the second end； Push element has one to push end, and plugs in what cylinder and can move corresponding thereto. Needle body has the needle body connector and a hollow needle tube being connected, and needle body connector has a needle tip to fixed what cylinder the second end, hollow needle tube. Needle tip security component plugs in the hollow stack shell of what and hollow needle tube, and can move corresponding thereto, and there is needle tip security component a syringe needle to hide set portion. The process that end is moved to cylinder the second end from cylinder first end is pushed, is that can contact and push needle tip security component, and so that syringe needle is hidden set portion and stretch out hollow needle tube, and be that can cover and prevent needle tip to outer contacting when being more than needle tip. Therefore this case has both automatic capping raising safety, needle tip security component quite can be assisted especially with having many advantages, such as upper cover direction guiding towards needle tip automatically.本創作係有關一種具針頭尖端保護蓋之注射針筒，其包括一筒體、一推壓元件、一針體及一針頭尖端安全組件。筒體具有一筒體第一端部及一筒體第二端部；推壓元件具有一推壓端部，並插設於筒體內而可與其相對移動。針體具有相連通的一針體接頭及一中空針管，針體接頭用以固定於筒體第二端部，中空針管具有一針頭尖端。針頭尖端安全組件插設於中空筒身與中空針管內，並可與其相對移動，針頭尖端安全組件具有一針頭遮套部。推壓端部從筒體第一端部移動至筒體第二端部的過程，係可接觸而推動針頭尖端安全組件，而使針頭遮套部伸出中空針管，並當超過針頭尖端時，係可遮蓋而防止針頭尖端對外接觸。故，本案兼具自動上蓋提高安全性、針頭尖端安全組件可自動朝向針頭尖端相當特別與具有上蓋方向導引輔助等優點。
