摘要： A band saw quickly changing device for a band saw machine is pivotally connected to a turning wheel of the machine body, including a sliding base, two limiting bases, a spring, a support plate, a micro-adjusting rod, a quickly adjusting device and a bottom base. The quickly adjusting device is composed of a shifting block, an eccentric block and a handling rod. The eccentric block has an eccentric shaft hole for pivotally connected on the shifting block, and the handling rod has a pivotal member formed in its upper end to fit in the eccentric shaft hole and fixed therein with a bolt. When the handling rod is swung backward, the sliding base is moved down to let the upper turning wheel move down, loosening the band saw extending around the two turning wheels of the machine.
