10. The feed mechanism as claimed in any one of claims 2 to 9, further comprising a drive portion for driving the slide box to ascend and descend, the drive portion being mounted on the mounting portion and connected to the slide box.

11. The feed mechanism of claim 10, wherein the drive portion includes a power assembly and a transmission assembly, the power assembly being fixedly mounted to the mounting portion, the power assembly being coupled to the slide box via the transmission assembly.

12. The feed mechanism as set forth in claim 11, wherein the transmission assembly includes a lead screw and a nut engaged with each other, the lead screw being connected to the power assembly, the nut being connected to the slide box; or

13. The feed mechanism as recited in claim 10, wherein the drive portion is located on one of two sides on which the elevator portion is mounted.

14. The feed mechanism as recited in claim 10, wherein a side of the slide box corresponding to the mounting portion is formed with a first recessed feature that at least partially receives the drive portion.

15. The feed mechanism as recited in claim 10, further comprising a buffer portion disposed between the mounting portion and the slide box, the buffer portion configured to prevent the slide box from descending under its own weight.

16. The feed mechanism as set forth in claim 15, wherein the number of the buffer portions is two, and two buffer portions are mounted to two side surfaces of the slide case which are opposite to each other.

17. The feed mechanism as claimed in claim 16, wherein the two mutually opposed sides of the slider box on which the buffer portions are mounted are aligned in a direction perpendicular to a direction of reciprocation of the diamond wire.

18. The feed mechanism as recited in claim 16, wherein each of two sides of the slide box corresponding to the buffer portion is formed with a second recessed structure that at least partially receives the buffer portion.

19. The feed mechanism of claim 15, wherein the buffer is a pneumatic, hydraulic, or electric cylinder.

20. A wire cutting machine characterized by comprising the feed mechanism of any one of claims 1 to 19.
