[0002] Head circumference refers to the circumference from the center of the eyebrows to the midline of the back of the head, which is usually closely related to the growth and development of the brain and skull. The growth of a baby's head circumference is closely related to the growth and development of the brain and skull. Generally, as the baby grows older, the head circumference will gradually increase.
[0003] The traditional way to measure a child's head circumference is to put a tape measure on the child's head, then pinch one end of the tape measure and the marked line with the hand, and finally observe the reading of the marked line. However, in actual use, young children are prone to move around during the measurement process. On the one hand, the tape measure shakes with the child's head, making it difficult to read the reading. On the other hand, it is easy to cause the pinching part to shift, which reduces the accuracy of the reading. There is still a certain inconvenience in actual use. Therefore, a tape measure for measuring the head circumference of children is urgently needed to solve the above problems. Utility Model Content
