On one side of the inner wall of the working box 1, a gear 5 is rotatably connected. On the circumferential side of the surface of the gear 5, two racks 4 are meshed and connected. The two racks 4 are slidably connected with the working box 1. The connecting plate 3 is tightly connected with one side rack 4. On one side of the top walls of the two racks 4, a connecting shaft 9 is tightly connected. On one side of the top wall of the connecting shaft 9, a slider 6 is tightly connected. On one side of the top wall of the slider 6, a clamping plate 7 is tightly connected. On one side of the top wall of the working box 1, two movable grooves 10 are opened. On one side of the top wall of the working box 1, a first guide rail 11 is tightly connected. The first guide rail 11 is slidably connected with the slider 6. On one side of the surface of the clamping plate 7, a waterproof soft rubber pad 8 is tightly connected. On one side of the surface of the waterproof soft rubber pad 8, a concrete test block 12 is movably connected.

[0024] In this embodiment, the user starts the first cylinder 2 installed inside the working box 1. Under the action of the first cylinder 2, the output end of the first cylinder 2 moves to drive the connecting plate 3 to move. The connecting plate 3 moves to drive one side rack 4 to move. The rack 4 is slidably connected with the working box 1 through a rack guide rail. One side rack 4 moves to drive the gear 5 to rotate. The gear 5 rotates to drive the two racks 4 to move. Under the action of the movable groove 10, the rack 4 moves to drive the connecting shaft 9 to move inside the movable groove 10.
