The size and shape of the outer surface of the convex rod 22 are adapted to the size and shape of the inner wall of the rectangular groove 24. A rectangular rod 25 is fixedly connected to one side of the cylinder 23. One end of the rectangular rod 25 away from the cylinder 23 is fixedly connected to one side of the conical cylinder 4. By arranging the cylinder 23, the slump of concrete can be detected. During testing, the cylinder 23 can be sleeved on the outer surface of the round rod 21 so that the convex rod 22 on the outer surface of the round rod 21 is located inside the rectangular groove 24 inside the cylinder 23. The cylinder 23 is controlled to slide downward so that the bottom end of the conical cylinder 4 is placed on the surface of the table body 1. Concrete is added to the inside of the conical cylinder 4. When the conical cylinder 4 is lifted after tamping the concrete, the outer surface of the rectangular rod 25 can be held to push the cylinder 23 to slide upward on the outer surface of the round rod 21, so that the conical cylinder 4 can move vertically upward, and the impact of the conical cylinder 4 on the concrete inside when moving upward is avoided as much as possible, which affects the collapse result of the concrete.

[0031] Reference Figure 1-4As shown, in this embodiment: a groove ring 27 is provided on the outer surface of the cylinder 23, and a groove rod 28 is fixedly connected to one side of the groove ring 27. A through hole 29 is opened on the outer surface of the groove rod 28, and a threaded cylinder 210 is rotatably connected to one side of the groove ring 27. Two screws 211 are threadedly connected to the inner wall of the threaded cylinder 210. The thread directions of the two screws 211 are opposite. One end of the two screws 211 is respectively fixedly connected to an L-shaped rod 212, and one end of the L-shaped rod 212 slides on the inner wall of the groove ring 27. The end of the L-shaped rod 212 away from the screw 211 is fixedly connected to a fan-shaped block 213. When the concrete inside the conical cylinder 4 is inserted and tamped, the groove ring 27 can be sleeved on the outer surface of the cylinder 23 to adjust the height position of the groove rod 28, and then the threaded cylinder 210 is rotated to make the two screws 211 move in the same direction on the inner wall of the threaded cylinder 210, and the fan-shaped block 213 is driven to move by the L-shaped rod 212. The two fan-shaped blocks 213 are close to each other and are pressed against the outer surface of the cylinder 23 to fix the position of the groove rod 28 outside the cylinder 23. The tamping rod is pushed through the through hole 29 to make the top of the tamping rod rotate inside the through hole 29, which can more conveniently control the tamping rod. One side of the fan-shaped block 213 is fixedly connected with a plurality of rectangular strips 214, and the rectangular strips 214 are rubber strips made of rubber.
