Description

Scissor with easy disassembly and automatic reset function

The invention relates to a pair of scissors, in particular to a pair of scissors that can be easily disassembled and has an automatic reset function, and belongs to the field of manual cutting tools.

Background technique

There are different types of scissors on the market, such as labor scissors for general paper cutting, gardening scissors for cutting branches, kitchen scissors for cutting food, bones, and so on. Kitchen scissors are in frequent contact with food. To ensure the hygiene of food and utensils, the two blades of kitchen scissors are usually detachable for easy cleaning.

Gardening scissors and kitchen scissors are generally used to cut 'hard' objects. Compared with labor scissors for paper cutting, users often need to open and close the scissors with greater effort. Therefore, 'the two handles of some gardening or kitchen scissors are connected by a spring. The maximum separation angle of the two handles is the state when the spring is relaxed. To cut the object, the user only needs to place the object on two blades. Between the mouth, and then force the finger to close the handle. If there is no spring between the handles, the user will need to spend extra effort to reopen the handle, and the spring between the handles saves this part of the user's strength. Once the user closes the scissors without force, the spring will automatically Bounce back and reopen the handle. However, 'Because a spring is installed between the two handles of this type of scissors, the user cannot separate the handle for cleaning', especially for kitchen scissors for food processing, which not only causes inconvenience to the user, but also affects hygiene . Therefore, a kind of scissors that can easily detach the handle and have the function of automatic reset is the market demand °
