Locking device for scanning assembly of ultrasound imaging apparatus and ultrasound imaging apparatus

An ultrasound imaging apparatus, comprising:

• an ultrasound transducer;
• and
• a locking apparatus, comprising:
• a scanning assembly connecting apparatus having a ball-head structure on a first end and a second end connected to the scanning assembly;
• a fixing member, connected to a main body of the ultrasound imaging apparatus, and comprising a hollow cavity, the ball-head structure being accommodated within the hollow cavity and movable within the hollow cavity;
• a pressing assembly, comprising a motor assembly, a cylinder assembly, and a pressing member, the cylinder assembly being disposed between the motor assembly and the pressing member, and cylinder gas pressure of the cylinder assembly being increased under the driving of the motor assembly, to drive the pressing member to press against the ball-head structure, thereby locking the scanning assembly;
• and
• a pressing assembly housing surrounding the pressing assembly,
• wherein the pressing assembly housing and the fixing member provide a common housing containing the pressing assembly and at least a portion of the ball-head structure.
