In the present application, the user holds the handle and extends the lower end of the collection tube into the concrete. When it reaches the specified depth, the user rotates the handwheel above the lifting rod to rotate the Z-axis screw, and then the linkage slide drives the outer lifting block to move upward, and the pulling rod drives the movable sealing plate to move up to release the blockage of the sampling port. Then the concrete flows into the collection tube from the sampling port. After the sampling is completed, the handwheel is rotated in the opposite direction to reset the movable sealing plate and move it downward to seal the sampling port. The collection tube can be pulled out of the concrete. Concrete of different depths can be sampled. It is flexible to use, easy to clean, and can be reused.
