Abstract
Claims
1. A method of manufacturing a lock that secures an unlocked key inside a box, comprising the following steps: (A) providing a box having a box body, a lid detachably connected to the box body, and a lock body disposed within a storage space defined by the box body; (B) inserting a key protrusion from the box body into a keyhole of the lock body and a keyhole of the box body, such that an extension of the key protrusion protrudes outside the box; (C) closing the lid and engaging it with the box body, and rotating the extension of the key protrusion to lock the box; (D) cutting off a portion of the extension to leave a key inside the box; (E) pushing the key into the storage space of the box.
2. The manufacturing method for locking the unlocked key inside the box as described in claim 1, wherein: In step (C), the extension of the key precursor is non-cylindrical, and the extension is rotated using an auxiliary tool.
3. The manufacturing method for locking the unlocked key inside the box as described in claim 1, wherein, Between step (B) and step (C), the following steps are also included: (F) After the key precursor is inserted into the keyhole, a thin rope is wrapped around one end of the key precursor and opposite to the extension and a rotating part with a through hole, so that both ends of the thin rope protrude outside the box.
4. A manufacturing method for locking the unlocked key inside a box as described in claim 3, wherein: In step (D), the key precursor also includes a shaft and a narrowing section. The extension transitions to the shaft via the narrowing section, the two ends of the string are tightened, a portion of the extension is cut off from the narrowing section, and the remaining extension becomes a stump, leaving the key inside the box.
5. The manufacturing method for locking the unlocked key inside the box as described in claim 4, wherein, Between step (D) and step (E), the following steps are also included: (G) After cutting off a portion of the extension, the ends of the rope are tightened and the stubble is smoothed with a file.
