Disclosed is a press-type disposable blood collector with a retractable-type head, comprising a shell (1), a stylet (3), a spring (4) and a pushing device (5), characterized in that the pushing device (5) is provided with a head-on combination of an inclined plane and a vertical plane corresponding to an elastic claw (7). The inclined plane is at the back and the vertical plane is at the front. The vertical plane is higher than the position of a critical unhooking point of the elastic claw (7), and at the same time is lower than the position of an end position point where the elastic claw (7) opens laterally. A space-occupying space (11) is provided between the vertical plane and the shell (1). During use, the head of the blood collector is aimed at a blood collecting location and is pressed the pushing device (5) moves backwards relative to the shell (1) the elastic claw (7) climbs along the inclined plane after the elastic claw (7) opens laterally at the critical unhooking point, the stylet (3) is ejected under the action of the spring (4) then, the elastic claw (7) slides to the vertical plane and the elastic claw (7) enters the space-occupying space (11), and at this moment, each elastic claw (7) clamps the pushing device (5) under the action of an elastic clamping force, and enables a protruding end of the pushing device (5) to be in a retracted state relative to the head of the shell (1). The present invention solves the problem of being unable to retract that head of a blood collector after same has been used, so that it is easy for a user to recognize the appearance of a blood collector head before and after same is used.Linvention porte sur un collecteur de sang jetable de type à pression avec une tête de type rétractable, comprenant une coque (1), un stylet (3), un ressort (4) et un dispositif de poussée (5), caractérisé en ce que le dispositif de poussée (5) est pourvu dune combinaison frontale, dun plan incliné et dun plan vertical correspondant à une gr
