Because the contact part of the adapter and the cone part 3 of the syringe in the prior art is small, the coaxiality is not favorably ensured during assembly. The existing adapter is clamped on the cone part 3 of the syringe, so that the contact length (area) of rubber in the protective cap and the outer wall of the cone part 3 of the syringe is limited, and the tightness is not guaranteed. The inner surface 12 of the fixing part in the scheme is in large-area contact with the outer wall of the needle cylinder 1, transition fit or interference fit is adopted, coaxiality is guaranteed, the adapter is not clamped on the conical part 3 of the needle cylinder, a protective cap with longer threads and inner cores can be used, and the product has good sealing performance.
The prior art glass syringe handles are at the syringe tip due to the inability of the glass article to be randomly shaped. In fact, some sizes of syringe handles are most suitable in the middle of the syringe due to the size of the hand. To facilitate the injection operation of the medical staff, as shown in fig. 6, preferably, an elongated sleeve for engaging with the outer wall of the needle cylinder 1 is connected to the fixing part, and a handle 23 protruding outwards is provided at the end of the elongated sleeve. 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 is fixedly connected with the outer periphery of the syringe 1 through fixing glue.

The invention has the following beneficial effects:
1) the problem that the adapter is not firmly connected with the outer sleeve of the glass syringe is solved by adopting colloid for fixation;
2) this adapter structure is longer than current adapter, and medical personnel can grasp the adapter surface with the hand when twisting the cap, and convenient operation and area of contact are big. After the cap is continuously screwed, the discomfort of hands can not occur.
3) The adapter is in large-area contact with the outer wall of the needle cylinder and is in transition fit or interference fit, coaxiality can be guaranteed, and the adapter has good sealing performance.
4) The adapter does not need to be clamped on the cone part of the syringe, can be suitable for a protective cap with longer threads and inner cores, and is favorable for the sealing property of products.
The invention also provides a syringe comprising the adapter. The derivation process of the beneficial effect of the syringe is substantially similar to the derivation process of the beneficial effect brought by the adapter, and therefore, the description is omitted. Preferably, the syringe provided by the invention is a glass syringe.
