The second drive device further includes a first linear slide rail fixedly and symmetrically arranged on the second support frame, a first slider slidably connected on the first linear slide rail, a platform bracket fixedly connected to the first slider, and the reducer mounted on the platform bracket.

5. The support mechanism for a stone cutting machine blade that is easy to quickly replace according to claim 1, characterized in that: It also includes a third driving device for horizontally translating the second support frame in a direction closer to / away from the first support frame. The third driving device includes a second linear slide rail and a reducer fixedly and symmetrically arranged on the first support frame. A second slider is slidably connected to the second linear slide rail, and a platform bracket is fixedly connected to the second slider. The reducer is mounted on the platform bracket. A hydraulic cylinder is provided on the first support frame at the position of the second linear slide rail for driving the second support frame to move back and forth, so as to drive the hydraulic cylinder to extend and retract, thereby moving the second support frame closer to / away from the first support frame.

6. The support mechanism for a stone cutting machine blade that is easy to quickly replace according to claim 1, characterized in that: A first locking assembly for locking the bearing housing and the second support frame is provided between them. The first locking assembly includes a first locking hole provided on the bearing housing, a second locking hole provided on the second support frame and corresponding to the position of the first locking hole, and a stop member locked between the first locking hole and the second locking hole.

7. The support mechanism for a stone cutting machine blade that is easy to quickly replace according to claim 1, characterized in that: A second locking assembly for locking the first support frame and the second support frame is provided between them. The second locking assembly includes a first locking groove provided at one end of the first support frame near the second support frame, a second locking groove provided on the second support frame and corresponding to the position of the first locking groove, and a stop member locking the first locking groove and the second locking groove.

8. The support mechanism for a stone cutting machine blade that is easy to quickly replace according to claim 7, characterized in that: It also includes a stop seat disposed on the first support frame or the second support frame. The stop member is hinged to the stop seat and can rotate relative to the stop seat in a direction toward or away from the first locking groove and / or the second locking groove, and cooperate with or separate from the first locking groove and the second locking groove, thereby locking or releasing the first support frame and the second support frame.

9. The support mechanism for a stone cutting machine blade that is easy to quickly replace according to claim 1, characterized in that: The first support frame includes a first support plate connected to the lifting frame and a second support plate connected to the second support frame. The first support plate and the second support frame are both vertically arranged, the second support plate is horizontally arranged, and the lower end of the first support plate is connected to the second support plate, and the upper end of the second support frame is connected to the second support plate. The lifting frame and the first support plate are respectively provided with a plurality of corresponding assembly holes, and each pair of corresponding assembly holes is equipped with an assembly part; wherein, each of the assembly holes on the support plate is an adjustment waist hole or a through hole.

10. A support mechanism for a stone cutting machine blade that is easy to quickly replace according to claim 9, characterized in that: The first support plate and the second support plate are each equipped with multiple reinforcing ribs.
