[0016] 2. In the present invention, by rotating the insert C, after the insert C is rotated out of the positioning insert C, the shift block B can be shifted upward, and the shift block B will drive the connecting plate B to move upward, so that the operation panel will rise upward, so that the operation panel can be more closely fitted to the arm of a small child. After adjusting the height of the operation panel, the motor is turned on, and the motor will drive the screw rod B to rotate. When the screw rod B rotates, it will drive the slider B to slide inside the operation panel, and the slider B will drive the partition to slide on the surface of the operation panel. After the partition completely blocks the child's sight, the child can be vaccinated. The adjustable design of the operation panel makes the operation panel suitable for people of different body shapes, including adults who are afraid of sharp objects or uncontrolled small children, and the movable design of the partition can prevent children from being frightened and distressed during vaccination.

[0017] 3. In the present invention, by placing electronic products such as mobile phones in the card slot and making the mobile phones such as electronic products fit on the surface of the support block, and then pulling the clamping block A outward, the clamping block A will drive the clamping block B to move outward, and then release the clamping block A. The clamping block A will be clamped by the tension of the tension spring A to clamp the mobile phone or electronic product, and then pull the clamping block B outward. After the mobile phone is placed inside the clamping block B, the clamping block B will be released. At this time, the clamping block B will clamp the surface of the mobile phone or other electronic products. After the mobile phone or other electronic products are fixed, the mobile phone can play cartoons for children who need to be vaccinated, thereby achieving the effect of diverting the children's attention, and also avoiding the situation that the mobile phone is knocked over when the child cries due to pain.
