Description

A portable pineapple paring knife [Technical Field]

The present invention relates to the field of pineapple paring knives and, more particularly, to a portable pineapple paring knife.

【Background technique】

Pineapple is a common fruit in people's daily life. Because it tastes sweet and sour, it is rich in vitamin C, and it also has the effect of promoting digestion, so it is deeply loved by people. Before eating a pineapple, you first need to cut off the skin of the pineapple. However, because the outer surface of the pineapple is more potent, it is not easy to peel.

In the prior art, a variety of pineapple paring knives are used to cut pineapple skin for consumption. Existing pineapple paring knives generally include a body and a blade that is integrally formed with the body. If the main body is set too long, the pineapple can be peeled off with a small force when using the pineapple paring knife, but the long body portion is easy to place and carry. If the main body is set short to facilitate placement and carrying, it is necessary to use a large force when peeling with a pineapple paring knife, which is difficult for some people with less effort.
