Description

Hand tool structure with replaceable blade

Technical Field

The utility model relates to a hand tool, in particular to a cutting hand tool with a replaceable blade.

Background

Before assembling a model, parts of the model are usually integrated on one or more model plates in an integrally formed manner, and therefore, when assembling the model, a user needs to use a hand tool such as scissors or scissors pliers to cut off a link between the part and the model plate so as to take the part off the model plate.

However, the use of common scissors or cutting pliers is prone to produce unevenness in the cut surface, and even because the scissors or cutting pliers are not sharp enough to make the cut surface white and not beautiful, users often choose special diagonal pliers with thin cutting edge and tight jaw engagement.

In order to meet the requirements of the precision operation, the existing commercially available model special-purpose diagonal pliers have the characteristics of complex manufacturing process and high cost, and the characteristics of thin cutting edge and tight jaw occlusion cause the inclined diagonal pliers to be easily damaged due to improper operation, so that the cutting edge is damaged or the occlusion is not tight. If the problems occur, the user can only buy a new special diagonal pliers, which causes waste. .
