Problems solved by technology

At present, there are mainly the following ways to carry keys: one is to hang multiple keys on the waist with key rings or key chains. Rubbing each other, making some unpleasant sounds, making people uncomfortable, and when people are walking, the keys and trousers will be damaged due to friction, and sometimes the keys will be lost due to the opening of the belt loop; The keys are strung together with key rings or keychains and placed directly in the pockets.

In addition, there are also the number of keys stored in the box. less disadvantages

The disadvantages of this structure are: the number of parts is large, the installation is cumbersome, and the spring force is prone to failure after repeated use, so the reliability of the action is poor, which affects the service life and increases the manufacturing cost; the number of stored keys is limited and the practicability is not strong
