The upper part of the cylinder 7 is connected to the upper part of the housing 1. The lower part of the telescopic part of the cylinder 7 is connected to the pressure plate 8. The extension of the cylinder 7 causes the pressure plate 8 to move downwards. The pressure plate 8 performs an impact test on the concrete. Limiting plates 9 are connected to the lower left and right sides of the inner shell 1. First tie rods 10 are slidably connected to the lower left and right sides of the outer shell 1. Clamping plates 14 are connected to the inner side of the first tie rods 10. The clamping plates 14 are located above the limiting plates 9 and are used to fix the concrete. Multiple openings are opened on the outer side of the first tie rods 10. Cleaning mechanisms for cleaning clamping plates 14 are provided on the left and right sides of the outer shell 1. Fixing mechanisms for fixing clamping plates 14 are provided on the outer walls of the left and right sides of the outer shell 1.

[0022] like Figure 3 As shown, the fixing mechanism includes a second fixing plate 11, a fixing rod 12, and a first elastic element 13. The lower part of the outer walls on both sides of the outer shell 1 is fixedly connected to the second fixing plate 11. The outer side of the second fixing plate 11 is slidably connected to the fixing rod 12. The second fixing plate 11 and the fixing rod 12 on the same side are fixedly connected to the first elastic element 13. The first elastic element 13 is wrapped around the fixing rod 12. The fixing rod 12 passes through one of the openings of the first pull rod 10. By passing the fixing rod 12 through one of the openings of the first pull rod 10, the first pull rod 10 is fixed, thereby fixing the clamping plate 14.

[0023] like Figure 3As shown, the cleaning mechanism includes a second pull rod 15, a second elastic element 16, and a push plate 17. The lower parts of the left and right sides of the outer casing 1 are slidably connected to the second pull rod 15. The inner side of the second pull rod 15 is fixedly connected to the push plate 17. The push plate 17 is used to clean the concrete debris in the clamping plate 14. The inner side of the second pull rod 15 passes through the upper part of the clamping plate 14.

Cylinder 7 and pressure display 2 are activated. The extension of cylinder 7 moves the pressure plate 8 downwards, compressing the concrete. Pressure display 2 monitors the pressure on the concrete. When the pressure reading on pressure display 2 reaches the construction standards or the concrete cannot withstand the pressure of pressure plate 8 and breaks, the extension of cylinder 7 retracts, moving pressure plate 8 upwards. Cylinder 7 and pressure display 2 are then deactivated. Pushing the second pull rods 15 on both sides inward, the second elastic elements 16 are both compressed. The second pull rods 15 drive the push plate 17 to move inward, cleaning the concrete in the clamping plate 14. Releasing the second pull rods 15 on both sides, the second elastic elements 16 reset, driving the second pull rods 15 to move outward. The second pull rods 15 drive the push plate 17 to move outward, and the storage box 3 collects the concrete after the test. After the test, pull out the storage box 3 by the handle 4, clean the concrete in the storage box 3, and push back the storage box 3. Drive the second pull rods 15 to drive the push plate 17 to move outward. 7. Move inward to clean the concrete inside the clamping plate 14, making the concrete impact test more convenient and reducing the burden of the concrete impact test.
