Meanwhile, the existing ultrasonic probe suspension device cannot store and organize the data cable connected to the probe when the probe is suspended. The data cable is much larger and hangs down directly. The hanging data cable may get tangled, affecting subsequent use.

At this time, two places on the ultrasonic probe are clamped and limited, which further improves the stability of the ultrasonic probe suspension; (4) The user can move the data cable of the ultrasound probe downward along the center of the two sets of shielding blocks. At this time, the data cable will push the shielding blocks to move to both sides. At this time, the shielding blocks are limitedly moved inside the sliding block along the fixed rod through the sleeve rod. At this time, the data cable is horizontally stored in the storage groove. The storage groove can limit the data cable to reduce the twisting and entanglement of the data cable when the device is in use. When the data cable does not squeeze the shielding block, the shielding block will reset under the elastic force of the reset spring. At this time, the shielding block blocks the upper side of the storage groove, thereby reducing the possibility of the data cable falling from the storage groove. (5) After the ultrasonic probe is suspended, the data cable can be folded and rolled up through the rotating shaft. At this time, the data cable can be stored under the rolling action of the rotating shaft, and the data cable can be further prevented from being entangled. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The user can place the ultrasonic probe in the hanging cavity 15 opened in the fixed box 2. At this time, the fixed box 2 can provide preliminary protection for the ultrasonic probe to reduce the damage of the ultrasonic probe caused by external impact. The user can move the ultrasonic probe data line down along the center of the two sets of shielding blocks 10. At this time, the data line will push the shielding block 10 to move to both sides.
