The embodiment of the present invention is described in detail below, and referring to fig. 1 to 6, the embodiment of the present invention provides a reusable resin plughole mat, which includes a substrate 100 and a plurality of support modules 200 with different sizes and shapes, wherein the substrate 100 has a plurality of predetermined through holes 110, and the plurality of support modules 200 can be spliced into a plurality of abdicating spaces 300 according to a desired plughole pattern and can be detachably fixed on the substrate 100. During the use, as shown in fig. 6, according to the required plug hole pattern, the multi-block support module 200 is used for combining and splicing the abdicating space 300 required by the plurality of resin plug holes, and the support module 200 is fixed on the substrate 100, so that the preset through holes 110 below the abdicating space 300 and the abdicating space 300 are utilized for resin plug hole, meanwhile, the multi-block support module 200 can also provide support for the resin plug hole, after the substrate 100 and the plurality of support modules 200 are manufactured for the first time, when the support module is used again, only different plug hole patterns need to be used, different support modules 200 are adopted for combination, so that different abdicating spaces 300 are obtained, the drilling file of the cushion plate does not need to be manufactured, the cushion plate does not need to be drilled again, the processing cost can be reduced, the time for processing is shortened, and the processing efficiency is improved.

Specifically, referring to fig. 1, the preset through holes 110 are provided with a plurality of rows, and every two adjacent rows of the preset through holes 110 are distributed in a staggered manner, so that the preset through holes 110 are densely distributed on the substrate 100, and therefore, the hole plugging patterns can be obtained in the later stage when resin is plugged, specifically, the size of the gap between every two adjacent preset through holes 110 is 0.2mm, and the gap of 0.2mm can make the preset through holes 110 on the substrate 100 distributed more densely, and can make the substrate 100 still have a certain supporting strength, so that the multiple support modules 200 can be stably installed in the later stage. Specifically, the aperture size of the through hole 110 is preset to be 1.5 mm-2.0 mm, the aperture of the through hole 110 is larger than the aperture of the through hole drilled on the traditional cushion plate, when the resin is plugged, the plugging pattern can be conveniently corresponded, although the number of the through holes 110 is preset to be more, the aperture is larger, certain drilling time is needed, after the substrate 100 is manufactured, the substrate can be repeatedly used for many times, drilling files and operation drilling are not required to be manufactured again, and the overall efficiency can be greatly improved.
