The syringe needle is promoted behind syringe inside, is stuck in the outside of the push rod；
The syringe needle is exited after the syringe, is spun off after the syringe needle, and the place that the safety pole retreats to the push rod is held with it
It is flat；The rubber stopper is in closed form；
The length of the safety pole is more than the length sum of the push rod and syringe needle.
A kind of safe syringe as described above, wherein, the outside of the connecting hole is provided with connecting seat, the connecting seat
It is integrally formed with the syringe.
A kind of safe syringe as described above, wherein, an in addition to needle cap, needle cap is connected to the connecting seat
On.
Compared with prior art, the beneficial effect that the utility model is produced is mainly reflected in：
1st, a kind of safe syringe of the present utility model, when injection, the syringe needle connects with the syringe for screw thread
Connect, will not be excessive because of pin cylinder pressure so as to cause the imagination that syringe needle comes off；
2nd, a kind of safe syringe of the present utility model, syringe needle is placed on the inside of syringe, is prevented before and is made
Medical personnel are stabbed after to cause unnecessary infection；
3rd, a kind of safe syringe of the present utility model, it has simple in construction, easy to use, low manufacture cost, profit
The characteristics of being widely popularized.

Embodiment
, now will be in conjunction with the embodiments to this practicality for the ease of understanding the purpose of this utility model, technical scheme and its effect
It is new to be elaborated further.
As depicted in figs. 1 and 2, a kind of safe syringe of the present utility model, including syringe 1 and push rod 3, the push rod
3 inside the syringe 1, and the push rod 3 is to be provided with hollow lever, the push rod 3 before safety pole 5, the safety pole 5
End is connected with syringe needle 2, and its rear end is provided with push handle 6, and the push handle 6 is located at the outside of the push rod 3；The syringe 1 insert
The side wall for entering syringe needle 2 is provided with connecting hole 7；The inwall of the connecting hole 7 is provided with internal thread；The remote needle point of the syringe needle 2
One end be provided with connecting rod 8, the safety pole 5 is set in the end of the connecting rod 8 of the syringe needle 2；The safety pole 5 with it is described
