In order to make carousel 2 rotate, fixed box 1 upper end be equipped with and place box 10, coaxial rotation is connected with pivot 11 in fixed box 1, pivot 11 and carousel 2 fixed connection, the upper end of pivot 11 runs through fixed box 1 and coaxial be equipped with and be located the worm wheel 12 of placing in the box 10, place the box 10 internal rotation and be connected with worm wheel 12 meshed worm 13, the front end of worm 13 runs through and places box 10 and be equipped with knob 14.

In order to improve the comfort of the infant, the splint 6 is an arc-shaped plate which is axially and outwards protruded from the upper part and the lower part, and a soft cushion 15 is arranged on the inner edge surface of the splint 6.

In order to improve the fixing effect, an elastic band 16 is arranged between the clamping plates 6 at the left side and the right side.

In order to limit the cover plate 9, a buckle 17 is arranged at the upper end of the cover plate 9, and a clamping block 18 capable of being inserted into the buckle 17 is arranged at the upper end of the clamping plate 6 at the front side.

In order to put the infusion tube into the placing groove 7, the left and right side walls of the placing groove 7 are respectively provided with a connecting groove 19 with a forward opening.

When the utility model is used, the initial state of the device is that the outer edge surface of the sliding shaft 4 is contacted with the inner side wall of the arc-shaped groove 3, and the cover plate 9 shields the placing groove 7;

when the puncture needle is inserted into the head of the infant, the device is taken out, the knob 14 is rotated clockwise, the knob 14 drives the worm 13 to rotate clockwise, the worm 13 drives the worm wheel 12 to rotate clockwise, the worm wheel 12 drives the rotating disc 2 to rotate clockwise through the rotating shaft 11, the rotating disc 2 drives the sliding shaft 4 to move outwards through the arc-shaped groove 3, the sliding shaft 4 drives the splint 6 and the soft cushion 15 to move outwards through the push rod 5,
