[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments.

[0041] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following combines Figures 1 to 7 to make a detailed description of the specific embodiments of the present utility model.

[0042] As Figures 1 to 7 shown, an embodiment of the present utility model provides a syringe protection device, including: an outer protection sleeve 100, the outer protection sleeve 100 is provided with a propulsion port 110 and a protection port 120; an inner protection sleeve 200, the inner protection sleeve 200 is arranged inside the outer protection sleeve 100; a propulsion member 300, the propulsion member 300 is arranged inside the outer protection sleeve 100 on the side close to the propulsion port 110; wherein, the inner protection sleeve 200 is movable inside the outer protection sleeve 100; a spring 310 is arranged between the propulsion member 300 and the inner protection sleeve 200; at least one propulsion groove 330 is arranged on the propulsion member 300.

[0043] Preferably, the syringe protection device includes an outer protection sleeve 100, an inner protection sleeve 200, and a propulsion member 300. The outer protection sleeve 100 is sleeved outside the inner protection sleeve 200.
