Referring to fig. 1, the fixing portion includes a fixing portion outer surface 9 and a fixing portion inner surface 12, wherein the fixing portion inner surface 12 is used for positioning the adaptor in a radial direction (coaxiality), a first glue groove 10 for accommodating fixing glue is provided on the fixing portion inner surface 12, i.e. an inner wall of the fixing portion, and further preferably, a glue injection hole 11 communicated with the first glue groove 10 is provided on an outer wall of the fixing portion, so that glue injection is conveniently performed after assembly, as shown in fig. 3. Of course, the glue injection hole 11 is not required, and when the glue injection hole 11 is not provided, the fixing glue is coated in the first glue groove 10, and then the assembly and the fixation are performed.
Further preferably, the second glue groove 14 for containing the fixing glue is also provided on the inner side of the outer port of the fixing portion, as shown in fig. 4, and the fixing glue is also provided on the outer port of the fixing portion, i.e., the tail end, so that the fixing effect of the fixing portion and the syringe 1 can be further enhanced. Ribs 13 may be provided in the inner surface 12 of the fixing portion, as shown in fig. 5, the ribs 13 also functioning as glue grooves.
It should be noted that, the inner surface 12 of the fixing portion and the outer wall of the syringe 1 may be in a transition fit or an interference fit.
As shown in fig. 1, preferably, the limiting part is a snap ring structure, the snap ring structure comprises a shoulder limiting surface 16 used for limiting and abutting against the syringe shoulder 2 and used for axially positioning the adapter, the surface, facing the opening end of the screwing part, of the other side of the snap ring structure is a protective cap limiting surface 15 used for limiting the screwing depth of the protective cap into the adapter, a fixing adhesive is arranged between the inner ring of the snap ring structure and the syringe cone 3, and the inner ring of the snap ring structure is a snap ring adhesive injecting surface 17, as shown in fig. 2.

It should be noted that the first glue groove 10, the second glue groove 14, the rib 13 and the snap ring glue injection surface 17 may be annular or discrete grooves.
Because the adapter in the prior art is shorter, medical staff can only pinch the outer surface of the adapter by two fingers when screwing the cap, and the operation is inconvenient. And because the outer surface of the adapter is provided with hard ribs, hand fatigue or discomfort can occur after the cap is continuously screwed. In order to solve the technical problem, the length of the original adapter can be greatly prolonged by the fixing part of the adapter, medical staff can grasp the outer surface of the adapter by hands when screwing the cap, the contact area between the hands and the outer surface of the adapter is increased, the operation is convenient, and the comfort level is improved.

The screw cap portion outer surface 6 and the fixing portion outer surface 9 may be provided with handle transverse ribs 18, longitudinal ribs 19 or frosting 20.
Because the contact part of the adapter and the needle cylinder cone part 3 in the prior art is smaller, the coaxiality is not guaranteed during assembly. The existing adapter is clamped on the syringe cone part 3 of the injector, so that the contact length (area) between the rubber in the protective cap and the outer wall of the syringe cone part 3 is limited, and the tightness is not guaranteed. The fixed part inner surface 12 in this scheme and the outer wall large tracts of land contact of cylinder 1 can be transition fit or interference fit, is favorable to guaranteeing axiality, and the adapter need not block at cylinder cone 3, can use the longer helmet of screw thread and inner core, makes the product have good leakproofness.
The glass syringe handles of the prior art are at the syringe end due to the inability of the glass article to be shaped at will. In fact, some syringe handles are most suitable in the middle of the syringe due to the hand size. In order to facilitate the injection operation of the medical staff, as shown in fig. 6, it is preferable that the fixing portion is connected with an elongated sleeve for cooperation with the outer wall of the cylinder 1, and the end of the elongated sleeve is provided with an outwardly protruding handle 23. It should be noted that, along the length direction of the syringe 1, the inner wall of the extension sleeve may be provided with a plurality of annular glue grooves or longitudinal glue grooves, and fixedly connected with the outer periphery of the syringe 1 through fixing glue.
