[0036] Specifically, such as Figure 1-3 As shown, the adjusting device 5 includes a connecting plate 51 with a limiting hole 52. An arc-shaped plate 53 is connected to one side of the connecting plate 51, and a groove 54 is provided in the arc-shaped plate 53. A sliding plate 55 is slidably connected in the groove 54. By setting the groove 54 and the sliding plate 55, the sliding plate 55 can slide freely in the groove 54 and can be limited by the housing 56 to prevent the sliding plate 55 from detaching from the groove 54 during sliding. The housing 56 is connected to the outside of the sliding plate 55, and the telescopic plate 6 is connected to one side of the housing 56. The limiting hole 52 is sleeved on the outside of the sliding rod 4. The two sides of the sliding plate 55 are tightly attached to the groove 54. A locking block is installed in the connecting cylinder 3. Several limiting holes 52 are provided in the sliding rod 4, and the locking block is locked in one of the limiting holes 52. By setting the connecting cylinder 3 and the sliding rod 4, the limiting block 83 in the connecting cylinder 3 can limit the limiting hole 52 in the sliding rod 4 to prevent the sliding rod 4 from shaking or moving.

[0037] During operation, when the injection offset needs to be adjusted, simply rotate the telescopic plate 6. The telescopic plate 6 will cause the housing 56 and the slide plate 55 to slide within the slide groove 54. After rotating to the appropriate offset, stop rotating the telescopic plate 6. Then, by pulling the telescopic plate 6, it can be extended above the target area. Stop extending the telescopic plate 6. At this point, the height of the connecting cylinder 3 can be adjusted to insert the injection needle 9 into the patient's body. After fixing the slide rod 4, the doctor can push the fixed injection needle 9. This ensures that the injection needle 9 will not shake or deviate during the injection process, and the positioning process can be quickly and accurately positioned to the target area through observation.

[0038] Second embodiment:

[0039] Specifically, such as Figure 3-4 As shown, the steering device 7 includes a connecting shell 71, which is fixedly connected to one side of the telescopic plate 6. A ball 72 is provided inside the connecting shell 71. A connecting rod 73 is connected to one side of the ball 72. A long rod 74 is connected to one side of the connecting rod 73. A threaded rod 75 is provided inside the connecting shell 71 and is locked outside the ball 72. A ball groove is opened inside the connecting shell 71. The size of the ball groove is slightly larger than the size of the ball 72, and the ball 72 is movably connected inside the ball groove. A through hole is provided inside the connecting shell 71, and an internal thread is provided inside the through hole. A threaded engagement is formed between the threaded rod 75 and the connecting shell 71. The fixing device 8 includes a long plate 81, which is connected to one side of the long rod 74. A pull plate 82 is connected below the long plate 81. A limit block 83 is connected to one side of the long plate 81. An injection needle 9 is locked inside the limit block 83. The shape of the limit block 83 is set as a semi-circle that is convenient for locking the injection needle 9 and has a certain degree of elasticity.

[0040] During operation, when different injection angles are required, the threaded rod 75 can be rotated counterclockwise to move the threaded rod 75 away from the ball 72. Then, the long rod 74 can be rotated to adjust the angle of the injection needle 9. When the appropriate angle is reached, the threaded rod 75 can be rotated clockwise to fix the ball 72, thereby achieving the adjustment of different angles of the injection needle 9.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
