Saw-band quick replacement mechanism for bandsaw machine

A saw-band quick replacement mechanism for a bandsaw machine, the saw-band quick replacement mechanism comprising:

• an immovable rack, defining a lift space that extends along a first direction;
• a sliding seat, being accommodated in the lift space and configured to move upward and downward along the first direction, wherein the sliding seat has a bottom provided with a first incline;
• a support member, having a second incline that is configured to abut against the first incline;
• and
• a control device, including a link, an eccentric member, and a handle, in which the link has one end connected to the support member and an opposite end connected to the eccentric member, and the handle is connected to the eccentric member to switch the eccentric member between a first position and a second position, so that when the eccentric member is in the first position, the support member props up the sliding seat, and when the eccentric member is rotatably switched from the first position to the second position, the eccentric member makes the link push the support member to move along a second direction that is perpendicular to the first direction, so that the second incline and the first incline slidingly move with respect to each other to make the sliding seat move downward.
