1) the nail pulling opening is thicker, and when the nail is tightly nailed, the nail opening cannot clamp the nail, so that the nail pulling effect cannot be realized;
2) the nail pulling port is the surface after forging or casting, the surface is rough, the appearance quality is poor, and the product grade is low;
3) the cutting edge is manually polished by a grinder or an abrasive belt machine, the uniformity of polishing size is poor, the surface is rough, the polishing surface is uneven, the appearance quality is poor, and the product grade is low.
Secondly, nail pulling openings and cutting edges of other nail extractors (see fig. 2) have the following main defects:
1) the nail pulling port is the surface after forging or casting, and has rough surface, poor appearance quality and low grade;
2) the end surface of the nail mouth is too sharp, the strength is low, and the defects of edge curling and the like are easy to occur;
3) the cutting edge is manually polished by a grinder or an abrasive belt machine, the uniformity of polishing size is poor, the surface is rough, the appearance quality is general, and the product grade is not high.
