When the saw band 13 is replaced, the cover 14 must be opened. Therefore, the timing of the cover 14 to be opened is also quite frequent. After multiple insertion and removal processes, the tenon 141 is prone to gradually lose its ability to buckle due to wear and tear. Therefore, it is known that after using the wrong machine 10 for a period of time, the cover 14 cannot be closely connected to the body. The robot 10 will generate vibration during operation, and it is more likely to cause the compliance cover 14 to be loosened from the body 11 and expose the flywheel 12 and the saw belt 13 in operation. This will cause danger to the operator. 5 200533460 [Summary of the invention] Therefore, the main object of the present invention is to provide a cover locking device of a band saw machine capable of sealing the cover tightly.
