Cutter body with replaceable blade and cutter

Abstract

The invention provides a cutter body capable of replacing a blade and a cutter, the cutter body comprises a cutter handle (1) and a cutter holder (2) connected to the cutter handle, the cutter holder (2) comprises two opposite clamping parts (21), and a blade groove (23) used for containing the blade (3) is formed between the two clamping parts (21); wherein the cutter holder (2) can rotate relative to the cutter handle (1) so as to be switched between a locking position and an unlocking position, in the locking position, the two clamping parts (21) clamp the blade (3), and rotation of the cutter holder (2) relative to the cutter handle is blocked; in the unlocked position, the width of the blade slot is greater than the thickness of the blade to allow the blade to be inserted into or removed from the blade slot. The knife body and the knife avoid knife sharpening operation, so that a knife sharpener does not need to be carried, the knife body and the knife are convenient to carry and operate, and cost is reduced; when the blade is abraded, only the blade needs to be replaced, the cutter body can be repeatedly used, and waste is avoided.

Description

technical field [0001] The present invention relates to a cutter, in particular to a cutter body capable of conveniently replacing blades and a cutter including the cutter body and the cutter. Background technique [0002] For existing knives with non-replaceable inserts, the cutting edge wears out during use. When the blade is not sharp enough, you need to sharpen the knife on the sharpener. And after many sharpenings, the blade gets narrower and narrower until the entire tool is discarded. Therefore, there are problems of complicated operations requiring sharpening and waste caused by discarding the entire tool. [0003] Moreover, for some knives, such as knives for repairing reeds (it should be noted that although the knives for repairing reeds are used as an example for description, the knives of the present invention are not limited to knives for repairing reeds, and can be used for In various uses and application occasions, and various specifications can be formed a...

And after many sharpenings, the edge gets narrower and narrower until the entire knife is discarded

Therefore, there is the problem of complex operation and the need to sharpen the knife, as well as the waste caused by discarding the entire knife

[0003] Moreover, for some knives, such as the knife for repairing the reed (it should be noted that although the knife for repairing the reed is used as an example in this paper, the cutter of the present invention is not limited to the knife for repairing the reed, and it can be used for In various uses and applications, and can be formed into various specifications according to needs), users often need to carry the knife with them for use at any time, and the existing knives are not portable enough due to the need to carry a sharpener at the same time
