2. The limiting tool according to claim 1, wherein a surface of each bearing plate, which is in contact with the sample plate, is provided with a barrier strip, and the barrier strips extend along the second direction;

the glue overflow groove is positioned at two sides of the barrier strip along the first direction and is close to the barrier strip.

3. The spacing tool of claim 2, wherein the barrier strip is located in a middle portion of the carrier plate along the first direction.

4. The spacing tool of claim 2, further comprising a plurality of locating pin assemblies, wherein the locating pin assemblies are positioned at two ends of the carrier plate along the second direction, and wherein the locating pin assemblies are configured to limit the sample plate along the second direction.

5. The limiting tool according to claim 4, wherein a surface of the bearing plate, which is in contact with the sample plate, is provided with a plurality of positioning holes;

the positioning pin assembly comprises a plurality of positioning pins, wherein the positioning pins are in one-to-one correspondence with the positioning holes and are respectively inserted into the corresponding positioning holes; and each locating pin inserted into each locating hole is used for limiting the sample plate along the second direction.

6. The limit tooling of claim 5, wherein the positioning pin is fixed to an upper one of the two adjacent bearing plates, and the positioning hole is located in a lower one of the two adjacent bearing plates.

7. The spacing fixture of any one of claims 1-6, wherein each of the carrier plates is provided with an machined prep groove located on a surface of each of the carrier plates in contact with the sample plate, and the machined prep groove is proximate to the spacing assembly.

8. The limit tooling of claim 2, wherein each limit assembly comprises two stop blocks disposed at two ends of the corresponding carrier plate along the first direction.

9. The limit tooling of claim 8, wherein each stop is detachably connected with the corresponding carrier plate through a threaded connection; in the same limiting assembly, the distance between the two stop blocks and the barrier strips along the first direction is adjustable.

10. The limit tooling according to claim 8 or 9, wherein each stop is provided with a support block, the support block is located at one end of each stop along the first direction, and the support block is close to one end of each bearing plate along the first direction;
