It should be noted that, in the conventional hardware cutting device 100, only one saw blade 14 is used, and when an object to be cut is cut, multiple operations are usually required to be performed back and forth to cut the whole object to be cut into multiple pieces, which is inconvenient. On the other hand, when the saw blades 14 of different sizes are required to cut the object to be cut, the conventional hardware cutting device 100 is inconvenient to replace the saw blades 14. The hardware cutting device 100 that this application document provided sets up a plurality of saw bits 14 in saw bit 14 group through setting up saw bit 14 group, can make a plurality of saw bits 14 cut one simultaneously and wait to cut the object, need not the operation of making a round trip many times again, just can become the polylith with waiting to cut the object cutting whole. The hardware cutting device 100 that this application document provided has solved only one saw bit 14 in having the technique, cuts inconvenient problem.

Optionally, the driving motor 10 may be a brushless dc motor, so as to avoid fire accidents caused by sparks generated at the electric brush. The brushless direct current motor is composed of a motor main body and a driver, and is a typical mechatronic product. Because the brushless DC motor is operated in a self-control mode, a starting winding is not additionally arranged on a rotor like a synchronous motor which is started under the condition of heavy load under the condition of frequency conversion and speed regulation, and oscillation and step-out can not be generated when the load suddenly changes. The permanent magnet of the brushless DC motor with medium and small capacity is mostly made of rare earth neodymium iron boron material with high magnetic energy level at present, and the volume of the rare earth permanent magnet brushless motor is reduced by one machine base number compared with a three-phase asynchronous motor with the same capacity.
