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.

Referring to fig. 1, fig. 2, fig. 3 and fig. 4, the present invention provides a technical solution: the utility model provides a medical syringe with adjustable, including urceolus 1, the lateral wall top of urceolus 1 is equipped with arc wall 11, arc wall 11 is fifteen, the inside wall slidable mounting of urceolus 1 has piston 2, the right-hand member fixed mounting of piston 2 has push rod 3, the lateral wall right-hand member of push rod 3 is equipped with mounting 4, mounting 4 is used for making things convenient for the dismantlement of pole setting 5 and push rod 3, be equipped with pole setting 5 on mounting 4, the top fixed mounting of pole setting 5 has horizontal pole 6, the left end fixed mounting of horizontal pole 6 has solid fixed ring 7, gu fixed ring 7's inside wall slidable mounting has slide bar 8, slide bar 8's bottom is equipped with elastic component 9, elastic component 9's bottom is equipped with arc piece 10, arc piece 10 is pegged graft.

Specifically, the fixing member 4 includes a snap ring 12, the top end of the snap ring 12 is fixed to the bottom end of the vertical rod 5, the right end of the side wall of the push rod 3 is provided with an annular groove 13, the snap ring 12 is snapped in the annular groove 13, the left and right width of the snap ring 12 is equal to the left and right width of the inside of the annular groove 13, the snap ring 12 shown in fig. 3 is in a normal state, and is in a deformed state when being snapped in the annular groove 13, and the two ends are away from the.
