Anti-sawing lock tongue
The invention relates to the technical field of lock tongues, and discloses an anti-sawing lock tongue which comprises a shifting piece, an anti-sawing structure and a plurality of patches, wherein the anti-sawing structure is arranged on the shifting piece, and the multiple patches are arranged on the two sides of the shifting piece in an overlapped mode respectively; the anti-sawing structure comprises a movably arranged metal block which can move relative to the shifting piece; when a person uses a tool to saw off the lock tongue to the position of the metal block, due to the fact that the position of the metal block is not fixed and the metal block can roll relative to the shifting piece and the connecting shaft, when the tool saws the metal block, the metal block rolls, the sawed position is changed continuously, and the sawing difficulty is increased; and the patches ware convenient to dismount and replace, and the thickness of the lock tongue can be changed by selecting the number of the mounted patches, so that lock slots of different dimensions are conveniently adapted.
本发明涉及锁舌的技术领域，公开了防锯断的锁舌，包括拨片、防锯断结构以及多个贴片；防锯断结构设置在拨片上，多个贴片分别叠合布置在拨片的两侧；防锯断结构包括活动布置的金属块，金属块可相对于拨片活动；当有人使用工具对锁舌进行锯断时，当锯至金属块的位置时，由于金属块的位置不固定，且可相对于拨片和连接轴滚动，当工具锯至金属块时，金属块滚动，导致被锯的位置不断改变，从而增大被锯断难度，且多个贴片的布置结构，便于拆装与更换，且可通过选择安装贴片的数量改变锁舌的厚度，从而便于适应不同尺寸的锁槽。
