Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Please refer to fig. 1-3, a syringe that conveniently operates prevents thorn protective sheath, including interior protective sheath 1, 1 overcoat of interior protective sheath is equipped with outer protective sheath 2, 1 one end of interior protective sheath is provided with location layer board 3, and location layer board 3 can be fixed convenient to use to the syringe. The inner protective sleeve comprises an inner protective sleeve 1 and is characterized in that a first elastic plate 4 is arranged on an outer ring close to one side of a positioning supporting plate 3, a clamping block 5 protruding outwards is arranged on the upper portion of the first elastic plate 4, a limiting block 6 is arranged on an outer ring far away from one side of the positioning supporting plate 3 of the inner protective sleeve 1, a clamping hole 7 matched with the clamping block 5 is formed in the upper portion of the outer protective sleeve 2, a second elastic plate 8 is arranged below the clamping hole 7, an inwards protruding abutting block 9 is arranged above the second elastic plate 8, and a first protrusion 10 and a second protrusion 11 are annularly distributed on an inner ring of the inner protective sleeve 1.
