The present invention discloses an anti-acupuncture structure and an anti-acupuncture intravenous infusion puncture needle, the anti-acupuncture structure comprising: a needle base, a first end of the needle base is used for fixing a needle head； a needle handle, the needle handle is fixed at a second end of the needle base； multiple sliding members, multiple sliding members are cylindrical with two open ends and mutually nested, and the sliding member in an innermost layer is slidably sleeved on the needle base, total length of multiple said sliding members in sliding direction is larger than length of the needle head； a first limit mechanism, the first limit mechanism is able to restrict relative slip between the sliding member in the innermost layer and the needle base, and is able to restrict relative slips among multiple said sliding members； a second limit mechanism, the second limit mechanism is arranged on the needle handle and the sliding member in the innermost layer, the second limit mechanism is able to restrict relative rotation between the sliding member in the innermost layer and the needle handle. With multiple sliding members being sleeved on the needle base in a layered way, improving safety and alleviating the pain of patients, meanwhile, the second limit mechanism is arranged, such that the sliding member in the innermost layer is unable to rotate relative to the needle base, thereby operating more easily.本發明揭露一種防針刺結構及防針刺靜脈輸液穿刺針。該防針刺結構包含：針座，針座的第一端用於固定針頭；針柄，針柄固定於針座的第二端；複數個滑件，複數個滑件為兩端開口的筒形並且相互嵌套，最裡層的滑件可滑動地套設於針座上，複數個滑件在滑動方向上的總長度大於針頭的長度；第一限位機構，第一限位機構能夠限制最裡層的滑件相對於針座的滑動，並且能夠限制複數個滑件之間的相互滑動；第二限位機構，第二限位機構設置於針柄和最裡層的滑件，第二限位機構能夠限制最裡層的滑件相對於針柄的轉動。藉由設置複數個滑件層套於針座，提高了安全性並減輕了患者的痛苦，同時，設置了第二限位機構，使得最內層的滑件不能相對於針座轉動，從而更易操作。
