[0024] The working principle of the above technical solution is as follows:

[0025] During use, after the external driving component drives the driving block 2, it can drive the drill barrel body 1 to rotate, drill holes in the concrete to take samples. After the drilling is completed, the drill barrel body 1 is taken out, and then the movable jacking mechanism 5 is put on the outer surface of the drill barrel body 1 to jack up the concrete block inside the drill barrel body 1, so that the concrete block is straightened inside the drill barrel body 1, which is convenient for the concrete block to be discharged to the outside.

[0026] In another embodiment, if Figure 1 As shown, a threaded ring 6 is symmetrically provided on the top of the drill tube body 1, and a threaded rod 7 is connected to the inner side of the threaded ring 6 through threads.

[0027] It is convenient to rotate the threaded rod 7 so that the threaded rod 7 moves downward inside the threaded ring 6, so that the bottom of the threaded rod 7 can push the concrete block so that the concrete block is discharged to the outside.

[0028] In another embodiment, if Figure 3 As shown, the movable jacking mechanism 5 comprises a first connecting sleeve block 8 , a connecting jacking block 9 is arranged on the inner side of the first connecting sleeve block 8 , and a fixed connecting block 10 is symmetrically arranged on the outer side of the surface of the first connecting sleeve block 8 .

[0029] It is convenient to sleeve the first connecting sleeve block 8 on the outer surface of the drill tube body 1, so that the connecting top block 9 can be inserted into the inner side of the fixed through groove 4, and the concrete block can be pushed and straightened, which is easy to operate.

[0030] In another embodiment, if Figure 3 As shown, a fixed connecting rod 12 is fixedly connected to the inner side of the fixed connecting block 10, and a second connecting sleeve block 11 is movably sleeved on the surface of the fixed connecting rod 12. An end of the fixed connecting rod 12 away from the fixed connecting block 10 is fixedly connected to a fixed connecting disk 13, and a force spring 14 is fixedly connected between one side of the fixed connecting disk 13 and an inner end of the second connecting sleeve block 11.

[0031] The fixed connection plate 13 is convenient to move under the action of the force spring 14, and pull the fixed connection rod 12, and then pull the fixed connection block 10, so that the first connection sleeve block 8 can be tightly stuck on the outer surface of the drill tube body 1, which is easy to operate.

[0032] In another embodiment, if Figure 3 As shown, a connecting spring 15 is fixedly connected to a side of the fixed connecting block 10 away from the fixed connecting rod 12 .

[0038] The working principle of the utility model is as follows: during use, the driving device drives the driving block 2 to drive the drill barrel body 1 to rotate, so that the concrete block can be drilled, and then the drill barrel body 1 is taken out of the concrete, and then the connecting spring 15 is pulled to drive the fixed connecting block 10, the first connecting sleeve block 8, the fixed connecting rod 12 and the fixed connecting plate 13 to move, and the force spring 14 is compressed between the fixed connecting plate 13 and the second connecting sleeve block 11, and the first connecting sleeve block 8 is sleeved on the outer surface of the drill barrel body 1, and the connecting spring 15 is loosened, and the fixed connecting plate 13 is compressed. It moves under the action of the force spring 14, and pulls the fixed connecting rod 12, and then pulls the fixed connecting block 10, so that the first connecting sleeve block 8 can be tightly stuck on the outer surface of the drill tube body 1, and the connecting top block 9 can be stuck on the inner side of the fixed through groove 4, to straighten the concrete block inside the drill tube body 1, so that the concrete block is easy to discharge. If it still gets stuck, the threaded rod 7 is rotated so that the threaded rod 7 can move on the inner side of the threaded ring 6, so that the bottom end of the threaded rod 7 can quickly push the top of the concrete, so that the concrete block is easy to discharge to the outside, and the operation is convenient.
