A safe blood lancet structure, applicable in the field of medical instruments, comprising a housing (1), a release apparatus (3), a power apparatus (4), a lancet fixing rod (2) arranged within the housing (1), and a blood lancet (8) fixed at the lancet fixing rod (2). A lancet outlet (11) is provided on either the release apparatus (3) or the housing (1). A positioning block for fixing the lancet fixing rod (2) is arranged between the lancet fixing rod (2) and the housing (1), or a connecting point having an easily split opening (12) is arranged between the lancet fixing rod (2) and the housing (1), or the lancet fixing rod (2) and the housing (1) are arranged independent of each other. This safe blood lancet, by arranging at the lancet outlet (11) a cocking plate (31) that issues a trigger signal for releasing the power apparatus (4) when moved to a blood sampling site, allows the housing (1) and the lancet outlet (11) to come into contact with the blood sampling site only towards the end of a blood sampling process, thus preventing changes in blood components and composition due to squeezing and pressing, ensurs detection precision, also allows the attention of a patient to be diverted, thus reducing pain, and is structurally simple, inexpensive to manufacture, and capable of effectively ensuring safe blood sampling.Linvention concerne un modèle de lancette de sécurité, relevant du domaine des instruments médicaux, et comprenant un boîtier (1), un dispositif de libération (3), un dispositif dentraînement (4), une tige de fixation de lancette (2) agencée à lintérieur du boîtier (1) et une lancette (8) fixée sur la tige de fixation de lancette (2). Un orifice de sortie de lancette (11) est prévu soit sur le dispositif de libération (3), soit sur le boîtier (1). Un bloc de positionnement servant à fixer la tige de fixation de lancette (2) est disposé entre la tige de fixation de lancette (2) et le boîtier (1), ou un site de raccordement à ouverture facile (12) est di
