AI Technical Summary

Problems solved by technology

[0005] However, since these door locks can only be opened and closed by the rotating operation of the handle, it is difficult to rotate and operate the above-mentioned handle when the user's hand is stained with slippery substances such as water, soap, or oil, causing the problem of inconvenient opening / closing

It is also difficult to open / close the door, especially for young children who cannot rotate the operating handle

[0006] Furthermore, since these door locks can only be opened / closed by rotating the handle, friction and wear between the same parts continue to occur during opening / closing, shortening the service life, and causing cost increases and frequent failures due to too many parts. The problem is that even if the above door is locked, the door can be opened with a blade, awl, iron wire, etc., which causes user anxiety and poor locking effect, etc.
