As a further technical scheme, sawteeth are respectively arranged on two opposite side surfaces in the infant umbilical clamp and the umbilical clamp, and strip-shaped grooves are formed in the middle positions of the sawteeth on the infant umbilical clamp. Whether the umbilical cord is clamped by the infant umbilical clamp is firm or not is the most important index for determining the quality of an umbilical cord cutter, the strip-shaped groove is arranged in the middle of the saw teeth, so that when the umbilical cord is extruded by the saw teeth of the infant umbilical clamp, the content of the umbilical cord can enter the strip-shaped groove to form middle bulge, and the shape of the umbilical cord is favorable for firmly clamping the umbilical cord by the infant umbilical clamp.

As a further technical scheme, the saw teeth on the two opposite side surfaces in the infant umbilical clamp and the umbilical clamp are meshed with each other. Therefore, the contact area for clamping the umbilical cord is increased, and the reliability of firm clamping of the umbilical cord is improved.

As a further technical scheme, the blade is obliquely and fixedly connected to the cutting part. The inclined arrangement of the blades allows the umbilical cord to be converted from a pure cut to a combination of a saw and a cut, which makes it easier to cut the umbilical cord.

As a further technical scheme, the closed ends of the infant umbilical clamp and the umbilical clamp are connected by an elastic piece extending in an arc shape. Thus, the umbilical cord clamp and the umbilical cord clamp are in an open state before clamping the umbilical cord, and the umbilical cord can be conveniently placed into the umbilical cord.

As a further technical scheme, one end of the elastic piece extends outwards in an arc shape to form a barrier strip which can prevent an umbilical cord from entering the infant umbilical clamp and the closed end of the umbilical clamp. This may block the umbilical cord from entering the closed end without the clamping function.

As a further technical scheme, the sliding guide mechanism comprises a bar-shaped guide structure and a convex-shaped guide structure, the bar-shaped guide structure comprises a bar-shaped bulge which is arranged on the upper side surface of the infant umbilical clamp and the umbilical clamp and extends along the length direction and a bar-shaped chute which is arranged on the lower side surface of the upper clamp plate and is matched with the bar-shaped bulge, and the convex-shaped guide structure comprises a convex-shaped bulge which is arranged on the lower side surface of the infant umbilical clamp and the umbilical clamp and extends along the length direction and a convex-shaped chute which is arranged on the upper side surface of the lower clamp plate and is matched with the convex-shaped bulge. The sliding guide mechanism is only provided with one of a strip-shaped guide structure and a convex-shaped guide structure, and the arrangement positions can be exchanged as long as the guiding function can be achieved. The utility model simultaneously arranges the strip-shaped guide structure and the convex guide structure and aims to improve the reliability of the guide function.

As a further technical scheme, a push rod extends out of one pressing strip of the umbilical clamp to the outer side of the opening end of the umbilical clamp, and a push part capable of pushing the infant umbilical clamp and the umbilical clamp to synchronously slide in the sliding guide mechanism is arranged on one side of the push rod facing the infant umbilical clamp. Therefore, the midwife can conveniently carry out umbilical cord cutting and the locking operation of the umbilical cord cut.

As a further technical scheme, the clamping frame is provided with pulling parts which can be matched with the pushing parts to act on two outer side surfaces of the upper clamping plate and the lower clamping plate respectively. Therefore, the midwife can conveniently carry out umbilical cord cutting and the locking operation of the umbilical cord cut.
