This work is about a kind of "hair sensor" which is applied to the soft and hard tissue of organism.The firing mechanism comprises a shell.Bottom cover,Drive assembly,Spring line and sensing assembly,Among them,The drive assembly has different degrees of rigidity of the firing spring and the return spring.And a top cover,Press handle and rotating seat,After firing the sensing component of the firing mechanism,Move the trigger unit and the connected sensing assembly to a specific travel distance and release the compression of the "engine spring".And when the force is released, it shows a positioning state.Contact the sensing component with the tissue under test.When the sensing is complete,Press the handle again to release the return spring from compression.At the same time, the pull rod will automatically stretch and reset.For the next measurement.本創作係有關於一種應用於生物體內組織軟硬度之撃發感測裝置，該擊發機構包含外殼、底蓋、驅動組件、彈簧管線以及感測組件，其中，該驅動組件具有不同程度剛性之擊發彈簧及復位彈簧，並設置有頂蓋、壓柄及旋動座，使擊發機構之感測組件擊發後，讓扳機組與連動之感測組件移動至特定行程距離並使撃發彈簧解除壓縮，且於解除施力時呈現定位狀態，使感測組件接觸於被測組織，而感測完成後，則再次下壓壓柄使復位彈簧解除壓縮狀態，同時將拉桿自動拉伸復位，以便進行下一次量測動作。
