In an embodiment of the invention, referring to Fig. 1, the device according to the invention comprises two parts, namely a cylinder A comprising a built-in (integrated) injection needle and a cylinder B cooperating with the cylinder, the cap B being placed over Above the cylinder to protect the exposed needle. The cylinder A is divided into two parts - the upper part 1 and the lower part 2, wherein the lower part 2 is fitted with the needle. The upper portion 1 and the lower portion 2 can be tightly coupled together, and when the upper portion 1 and the lower portion 2 are joined together, the needle can be exposed to the outside of the cylinder at an appropriate length to facilitate the injection.

Further, referring to Figures 1 and 2, the lower portion 2 of the cylinder A is composed of a needle 21 and a needle casing 22. The needle casing 22 is divided into three parts, a front section 23, a middle section 24, and a final section 25. The front section 23 is cylindrical and the outer wall of the front section is provided with an external thread, and the top wall of the front section 23 is provided with a circular hole 26. The middle section 24 has a truncated cone shape and extends downward and outward from the bottom of the front section 23. Formed. The last section 25 is still cylindrical and is connected to the middle section 24. The tail portion of the needle 21 extends to both sides and is integrally coupled to the inner wall of the needle casing 22 such that the needle 21 and the needle casing are inseparable. The front portion of the needle 21 extends through the circular hole 26 out of the lower portion 2. The inner diameter of the end section 25 is substantially the same as the barrel diameter of the used syringe, whereby when the cylinder A is coupled to the barrel, the end section 25 of the needle casing 22 can be used with appropriate tightness. A part of the syringe is placed in the end section, so that the syringe can be prevented from falling off when the device is held by hand.

The upper portion 1 of the cylinder A is also cylindrical, and the upper portion 1 is provided at the center of the lower end with a hollow cylinder 11 that cooperates with the front portion 23 of the lower portion 2. The inner wall of the cylinder 11 is formed with an internal thread that cooperates with the external thread of the front section 23 of the lower portion 2. When the upper portion 1 and the lower portion 2 of the cylinder A are connected, the internal thread of the cylinder 11 is engaged with the external thread of the front section 23, so that the upper portion 1 and the lower portion 2 of the cylinder A can be tightly joined together. The bottom end 14 of the upper portion 1 has a truncated cone shape and is formed to extend outward and downward from the cylinder 11. The bottom end 14 cooperates with the middle section 24 of the lower portion 2 so as to be able to be tightly connected when the upper portion 1 and the lower portion 2 are joined. Corresponding circular holes 12 and 13 are respectively formed on the top end wall of the upper portion 1 and the top end wall of the cylinder 11, and when the upper portion 1 is connected to the lower portion 2, the needle 21 can be exposed to the cylindrical barrel A through the circular holes 12 and 13 outer.
