A pressing type disposable safety lancet with spring pilot structure consists of a shell, a lancet core, a spring and a trigger； wherein: the spring is provided with a pilot structure at the outside to make the elastic force of the spring act along the ejection direction of the lancet core； the locking mechanism is formed by the cooperation of the elastic clamp at the tail of the trigger and the lancet core； the unlocking mechanism is formed by the front of pilot structure and the end of the elastic clamp through the unlocking bevel； when it's pressed during the use, the trigger moves backwards in the shell, the front of the pilot structure forces the end of the elastic clamp to open under the action of the unlocking bevel, and the lancet core is fired for puncturing under the action of the spring after the hook unhooks from the locking critical point. The solution associates the spring pilot structure and the unlocking mechanism and skillfully uses one structure for two functions, thereby achieving the dual effect of piloting and unlocking and reducing the shaking of the needle tip, simplifying the structure and reducing the cost.
