Design can produce a variety of flexible changes that increase complexity.

In this way, if the thief wants to use the straight bar-shaped unlocking tool to steal the screw-type lock core structure, the lock cylinder 21 of the screw-type lock core structure is in a spiral state, resulting in a straight-rod unlocking tool. It is difficult to move in the lock passages 21, so that it cannot effectively explore or push the lock pieces 31 of the card set 3 to move radially, and there are a plurality of the lock passages 21 (two are shown in this embodiment). In order to achieve the unlocking state, all the locking pieces 31 must be synchronously reached to the set position. If the same number of unlocking tools are not used in synchronization with the locking passages 21, all the locking pieces 31 cannot be moved synchronously, which also increases the spiral type. The difficulty in stealing the lock cylinder structure has indeed improved the anti-theft effect of the screw-type lock core structure.

In summary, the present invention has a screw-type lock core structure with a locking piece and a screw-type key, and the spiral lock of the screw-shaped key is matched by the locking lock 21 of the lock core 2 The leaf 61 and the uniquely designed locking pieces 31 and the locking groups 3 are used to improve the difficulty of theft and to improve the safety of the locking device, so that the purpose of the novel can be achieved.

However, the above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, that is, the simple equivalent changes and modifications made in accordance with the scope of the present patent application and the contents of the patent specification, All remain within the scope of this new patent.
