The present invention relates to a blood sugar and fruit sugar tester, comprising a cannula, a testing device and a probe. The cannula has a hollow tube on which a presser is provided； the presser extends inward the hollow tube to form a hook part which can be engaged with the tenon of the testing device； the top opening of the hollow tube is screwed with a top cover, and an elastic member is disposed between the top cover and a slide block； the slide block of the testing device is received in the hollow tube, and the outer portion of the slide block is protrudingly provided with a tenon for engagement with the hook part； a detector is disposed in the slide block, and the bottom of the slide block is passed through by a chamber upwardly, in which a probe can be placed for connection with the detector. The present invention uses a hollow tube in which a slide block is arranged, wherein the slide block can be shifted and triggered by an elastic member, such that the probe on the slide block may carry residual glucose of the specimen, and the detector may detect and calculate the sugar concentration and display the same on the display board. Thus, the present invention provides the advantages of high portability, rapid detection of sugar content and reduced production costs so as to increase the practicability.本發明係有關一種血糖及水果糖份測試機，其包括套管、檢測裝置與探針所構成，該套管之中空管體上設置有一壓塊，其壓塊向中空管體內部延伸有一勾部，而勾部係可與檢測裝置之凸榫相互扣合，另外該中空管體頂側開口端螺固有一上蓋，其上蓋與滑動塊之間則裝設有一彈性元件，而檢測裝置之滑動塊係容置於中空管體內部，且滑動塊外側凸設有一凸榫可與勾部相互扣合，而滑動塊內部設置有一檢測器，另外該滑動塊底側向上穿設有一容室，其容室內可供置放一探針接合至檢測器上者，其發明係藉由一中空管體的內部容置有一滑動塊，而滑動塊可藉由一彈性元件的彈移作動擊發，使得滑動塊上的探針殘有檢體之葡萄糖，進而讓檢測器偵測運算糖份濃度並顯示於顯示板上，藉之，該發明具有方便攜帶、快速檢測糖份含量及節省製造成本之優點，進而提升其實用價值。
