Description

Fire scene cutting machine convenient to change blade Technical Field The utility model relates to the technical field of cutting machines, in particular to a fire scene cutting machine with blades convenient to replace. Background In the prior art, conventional fire cutters often have problems during blade replacement and installation. Firstly, the replacement of the blade is inconvenient, often requiring the use of complex tools and more steps, which not only increases maintenance time, but also results in a lower operating efficiency for the operator. In emergency environments such as fire, time is critical, and any delay may affect the progress of the operation and even the rescue effect. Therefore, a need exists for a cutting machine that has a quick and more convenient blade change mechanism. Secondly, the fixed effect of installation of blade is poor, and in some current designs, the blade probably relies on traditional bolt or joint device to fix, and these fixed modes often are not firm enough, and in long-time use, the blade can appear not hard up condition, influences the cutting effect, brings the potential safety hazard even.
