[0039] Working principle: When it is necessary to limit the patient's wrist, simply press switch 21 to start motor 11, which causes the central shaft 10 to rotate, thereby driving the rotating column 3 to rotate. The first gear 4 in the middle rotates, which drives the meshing second gear 5 to rotate, causing the threaded column 6 in the middle to rotate. This causes the silicone column 8 on the outer wall to extend to the right, thereby achieving the effect of fixing and limiting the movement of the arm, ensuring that it will not easily shift during the puncture process, and making the staff more efficient.

[0040] When the patient's arm is placed inside the placement slot 13, it first contacts the central support bar 206 and the side support bar 207. Then, the downward pressure causes the top sleeve 204 to slide to the bottom, and the internal spring 203 is compressed, causing the entire arm to sink in. There are multiple such structures inside the placement slot 13. This structure is highly comfortable and can freely adapt to the different sizes of the patient's arm to meet the needs of different people.
