[0037] The outer end of the connecting portion 22 is connected to the hand-held portion 21, and the outer end of the connecting portion 22 is connected to the middle part of the hand-held portion 21. In this way, when using, when holding the hand-held portion 21, it helps to balance the overall weight and improve the stability of the use of the veterinary color ultrasound machine.

[0038] The inner and outer ends of the connection part 22 are both arranged in a flared shape, which increases the connection area between the connection part 22 and the body 1, and increases the connection area between the connection part 22 and the hand-held part 21; and improves the connection stability between the body 1, the connection part 22 and the hand-held part 21.

[0039] The hand-held portion 21 is arranged in an ellipsoidal shape, which is convenient for holding.

[0040] The control button 3 is arranged at the top of the hand-held part 21; according to the usage habits, the user can control the control button 3 by corresponding the index finger or the middle finger on the control button 3; in this way, during use, the required detection image can be captured by applying pressing pressure by the index finger or the middle finger, which is simple and quick to operate, and greatly facilitates the use of the veterinary color ultrasound machine.

[0041] The cross-sectional area of ​​the hand-grip portion 21 gradually increases and then decreases from the inner end to the outer end of the hand-grip portion 21 , which makes it easier for the hand to tightly grasp the hand-grip portion 21 , maximizes the contact area between the hand and the hand-grip portion 21 , and improves the firmness of the grip of the hand-grip portion 21 .

[0042] The top of the hand-held portion 21 includes a horizontal section and two inclined sections, the two ends of the horizontal section are respectively connected to the inner ends of the inclined section, and the outer ends of the inclined sections are gradually inclined downward in a direction away from the horizontal section; the control button 3 is set on the horizontal section; in this way, when the hand-held portion 21 is tightly grasped, the fingers correspond to the horizontal section, and the index finger and the ring finger correspond to the two inclined sections respectively; it is convenient for the middle finger to be arranged correspondingly to the control button 3, so that the middle finger can operate the control button 3.

In this way, according to the size of the user's palm, different stacked bonding arrangements are selected for the outer belt strip 42 and the inner belt strip 41 to meet different usage requirements.

[0046] That is to say, if the user's palm is small, the diameter of the inner strip 41 is reduced until the inner strip 41 is able to apply the tightening force. If the user's palm is large, the diameter of the inner strip 41 is expanded to avoid excessive tightening force applied by the inner strip 41, which may cause squeezing of the hand and injury to the hand.

[0047] Alternatively, the fastening belt 4 is elastically arranged, and the fastening belt 4 applies a fastening force through elasticity; under the effect of the elasticity of the fastening belt 4, the firmness of the grip of the handheld portion 21 is enhanced.

[0057] The alignment layer 12 is elastically arranged to play a buffering role, thereby preventing the weight of the body 1 from being applied to the arm during use, thereby reducing damage to the arm caused by the body 1.

[0058] The outer end surface of the alignment layer 12 is convexly provided with a plurality of protrusions to enhance the friction between the alignment layer 12 and the arm and enhance the safety of use.

[0059] The shoulder strap 6 includes an inner shoulder strap 6 and an outer shoulder strap 6. The inner shoulder strap 6 and the outer shoulder strap 6 are respectively arranged in a long strip shape. Along the width direction, the inner shoulder strap 6 and the outer shoulder strap 6 are connected. The outer end surface of the inner shoulder strap 6 and the outer end surface of the outer shoulder strap 6 are arranged flush, and the inner end surface of the inner shoulder strap 6 and the inner end surface of the outer shoulder strap 6 have a thickness difference. When worn, the inner end surface of the inner shoulder strap 6 and the inner end surface of the outer shoulder strap 6 are respectively attached to the shoulders; and when worn, the inner shoulder strap 6 is arranged inwardly, and the outer shoulder strap 6 is arranged outwardly.

[0060] In this way, when the veterinary color ultrasound machine is worn, the inner shoulder strap 6 and the outer shoulder strap 6 can prevent the shoulder strap 6 from sliding outward, thereby improving the wearing and using stability of the veterinary color ultrasound machine.

[0061] The handheld veterinary color ultrasound machine includes a detector, which is used to scan the patient's test part. The test data is transmitted to the body 1 and the image is presented through the display screen 11.
