[Prior art]

 A key is a tool that modern people need to use universally in their daily lives, and if you have too many keys in pieces, it will take time to find them when needed, and it is very inconvenient to carry. , A key holder that skews keys has been invented. In terms of gathering the keys that they own, it is relatively orderly in terms of the overall spatial form, is relatively convenient to use, and eliminates the need to spend excessive time searching for keys. Therefore, various key holders are designed.

Early key chains were relatively time consuming and inconvenient, requiring the key to be placed or removed from the metal ring in two layers one by one. Therefore, a key collection device with a control button was designed in the past. It made it even more convenient to put or remove individual keys. However, a key collection device with a control button requires an exposed control button to be installed, and operating the extremely small control button with a finger is not ideal in operation.

Also, recently, a design has been made in which a key can be directly put in or taken out and the correlated exposure control button is effectively omitted. One example is the "compression lock type keyboard structure". It is provided with one collecting board having a lock groove in the periphery, and a storage tank and one spring switch which communicate with the lock groove are provided in the board. Such a structure is quite convenient when putting a key on the keyboard, and the movable key ring slide member that holds the key can be easily press-fitted into the storage tank of the keyboard via the spring switch, or it can be operated in the opposite direction. I was able to take it out. However, after a large number of keys have been placed in the keyboard, if you try to take out the rear key, it has only a single exit, so after removing the front key one by one, For the first time, the key could be taken out, which was quite troublesome and needed improvement.
