摘要：
A kind of syringe with extension type needle cover includes a syringe, a syringe needle and an extension type needle cover. Syringe includes a nozzle. Syringe needle is arranged what nozzle. Extension type needle cover covers sleeve, a trigger member and an elastic element including a basal wall, a fixed trip, a fixes sleeve, one, covers sleeve with an opening, trigger member has one to trigger trip, and defines a press section. Trigger member can be relative to mobile one stowed position of what of the fixed trip of what and an extended position, what stowed position, trip is triggered far from fixed trip, it covers sleeve and fixes sleeve covers syringe needle jointly, what extended position, trigger card joggle closes the fixed trip of what, covers sleeve and covers fixes sleeve, is open exposed for syringe needle. Using Hou, the press section for only pressing trigger member returns to stowed position, prevents that syringe needle is exposed and more safety.一種具有可伸縮式針蓋的注射器，包含一針筒、一針頭及一可伸縮式針蓋。針筒包括一噴嘴。針頭套設於噴嘴。可伸縮式針蓋包括一基壁、一固定卡榫、一固定套筒、一遮覆套筒、一觸發件，及一彈性元件，遮覆套筒具有一開口，觸發件具有一觸發卡榫，並定義一按壓部。觸發件可相對於固定卡榫移動於一收合位置與一伸出位置，於收合位置，觸發卡榫遠離固定卡榫，遮覆套筒與固定套筒共同遮覆針頭，於伸出位置，觸發卡榫接合於固定卡榫，遮覆套筒遮覆固定套筒，開口供針頭外露。使用後，僅按下觸發件的按壓部回到收合位置，杜絕針頭外露而更具安全性。
