[0002] During the construction process in the construction industry, it is necessary to frequently inspect the concrete used. Concrete test block inspection is one of the conventional means of inspection. When making concrete test blocks, after pouring the concrete in the mold, it needs to be placed on a concrete specimen vibration device for compaction.

The specimen mold box in the prior art is only placed on the upper end surface of the concrete specimen compaction device. During the concrete compaction process, the specimen mold is prone to slip on the vibration table, thereby causing the concrete in the specimen mold to spill out, and it is also easy to cause the specimen mold to tip over;
