Safety cutter knife that doesn't cut hands

摘要

The present invention relates to a cutter knife widely used mainly for stationery/office work for cutting thin objects such as paper, vinyl, film, string, thread, etc. It relates to a safety cutter knife that does not cut hands that can prevent accidents. The present invention has the effect of preventing the cutter blade from sliding arbitrarily regardless of the user's intention by allowing the cutter blade to be fixed during use. As the operator's hand falls, the spring's elasticity acts as the safety cover automatically protrudes so that the tip of the cutter blade (the end protruding outside the body housing) can be safely covered. The protruding cutter blade is safely protected by the safety cover, and there is an effect to prevent a safety accident. While holding the cutter knife horizontally, the pencil is seated in the incision for the pencil sharpener, and the pencil is pushed and pulled with your finger. The expected effect, such as safe and easy cutting, is a really beneficial design.
