Preferably, the locking assembly comprises a stud 26 passing through the housing 21, and a clamping plate 27 fixedly connected to the end of the stud 26 passing through the housing 21.
Therefore, the ultrasonic probe is placed in the wall cylinder of the clamping plate and the seat cylinder, the stud is manually screwed, the clamping plate is forced to approach the ultrasonic probe, and the ultrasonic probe is clamped to prevent the ultrasonic probe from moving relative to the seat cylinder.
Preferably, the rotating part is provided with a clamping groove 24, and the puncture needle 3 is arranged in the clamping groove 24.
Therefore, the puncture needle is clamped in the clamping groove and can move back and forth along the clamping groove, and the depth of the puncture needle in a target blood vessel is convenient to adjust.
Preferably, the rotating member is a rotating disc 23, and the engaging groove 24 is convexly disposed on the upper surface of the rotating disc 23.
Preferably, the rotating disc 23 is provided with a handle 25 for rotating the rotating disc 23.
The puncture needle is fixed on the central plane of the length direction of the cylinder wall of the seat cylinder for puncture, so that the puncture efficiency is improved, the puncture positioning is more accurate, and the pain of a patient is reduced.
