[0021] In the present solution, a retractable positioning member 3 is provided on the outside of the drill barrel 52, so that the moving direction of the drill barrel 52 can be positioned during the sampling process of the drill barrel 52, so that during the drilling process, the center line of the drill barrel 52 and the center lines of the first sealing cylinder 31, the second sealing cylinder 32 and the third sealing cylinder 33 are always on the same horizontal line, thereby ensuring the sampling quality of the device, and a closed space can be formed between the first sealing cylinder 31, the second sealing cylinder 32 and the third sealing cylinder 33 and the wall or the ground, so that the drill barrel 52 can drill in a closed space, so that the dust generated by the drill barrel 52 during the sampling process will not spread to the outside, thereby improving the dustproof effect of the device, and at the same time, the first sealing cylinder 31, the second sealing cylinder 32 and the third sealing cylinder 33 can be used to collect the dust generated during the sampling process, thereby reducing the subsequent cleaning work of the user, making it more convenient for people to use.

[0022] exist Figure 1Middle: A fixing plate 2 is fixedly installed on one side of the mounting plate 1, and a positioning piece 3 is fixedly installed on the other side of the fixing plate 2. A sampling piece 5 is fixedly installed at the center of the side of the mounting plate 1 away from the fixing plate 2, and a handle 11 is provided above the sampling piece 5. The handle 11 is fixedly installed on one side of the mounting plate 1. When sampling the wall or the ground, the handle 11 is manually gripped to drive the device to move along the inside of the concrete, thereby driving the sampling piece 5 to sample the concrete. A pad 4 is fixedly installed on the side of the third sealing cylinder 33 away from the second sealing cylinder 32 to increase the contact area between the third sealing cylinder 33 and the concrete surface to prevent the third sealing cylinder 33 from having a small contact area with the concrete surface and a large pressure, thereby causing damage to the concrete.

[0023] exist Figure 2 Middle: The sampling component 5 includes a driving motor 51 and a drill barrel 52 . The driving motor 51 is electrically connected to an external power source. The output end of the driving motor 51 passes through the mounting plate 1 , the fixing plate 2 and is fixedly connected to the drill barrel 52 . The drill barrel 52 is located inside the first sealing tube 31 .

[0024] exist Figure 3In the figure, the positioning member 3 includes a first sealing cylinder 31, a second sealing cylinder 32 and a third sealing cylinder 33. The first sealing cylinder 31, the second sealing cylinder 32 and the third sealing cylinder 33 are connected. The outer wall of the first sealing cylinder 31 is provided with a connecting port 311, and the connecting port 311 can be connected to an external dust collection device. When the sampling amount is large and the dust is large, the dust can be transported to the outside through the connecting port 311. The second sealing cylinder 32 is sleeved on the outside of the first sealing cylinder 31, and the third sealing cylinder 33 is sleeved on the outside of the second sealing cylinder 32. The second sealing cylinder 32 is slidably connected to the first sealing cylinder 31, and the third sealing cylinder 33 is slidably connected to the outside of the second sealing cylinder 32, so that the positioning member 3 is pressed against the concrete. Since the positioning member 3 is retractable, when it is manually pressed downward, the third sealing cylinder 33 slides toward the inside of the second sealing cylinder 32 through the slider 36, and the second sealing cylinder 32 is received in the inside of the first sealing cylinder 31 through the slider 36, thereby realizing the contraction of the positioning member 3. A placement cavity 35 is provided on the inner wall of the sealing cylinder 33, and a slider 36 is fixedly installed on the outer wall of the end of the first sealing cylinder 31 and the second sealing cylinder 32 away from the mounting plate 1. The slider 36 is slidably connected inside the placement cavity 35. The placement cavity 35 is used to place an elastic member 37 to provide space for the installation of the elastic member 37. A sealing ring 34 is fixedly installed on the end of the first sealing cylinder 31 and the second sealing cylinder 32 away from the mounting plate 1. The first sealing cylinder 31 is sealedly connected to the second sealing cylinder 32 through the sealing ring 34, and the second sealing cylinder 32 is sealedly connected to the third sealing cylinder 33 through the sealing ring 34. Since the sealing ring 34 is fixedly installed on the end of the first sealing cylinder 31 and the second sealing cylinder 32 away from the mounting plate 1, a closed space can be formed between the first sealing cylinder 31, the second sealing cylinder 32 and the third sealing cylinder 33 and the wall or the ground, so that the drill tube 52 can drill in a closed space, so that dust generated by the drill tube 52 during the sampling process will not spread to the outside, thereby improving the sealing performance of the positioning member 3.

[0025] exist Figure 4In the figure, an elastic member 37 is fixedly installed inside the placement cavity 35, and the other end of the elastic member 37 is fixedly connected to the slider 36. The elastic member 37 includes an inner rod 371, an outer rod 372 and a spring 373. The inner rod 371 is slidably connected to the inside of the outer rod 372, and the spring 373 is sleeved on the outside of the inner rod 371 and the outer rod 372. Under the action of the spring 373 inside the elastic member 37, the positioning member 3 is always in an open state when it is not subjected to force. After the sampling is completed, under the action of the spring 373, the first sealing cylinder 31, the second sealing cylinder 32 and the third sealing cylinder 33 are restored to their original states. When the drill tube 52 is moving for sampling, the first sealing cylinder 31, the second sealing cylinder 32 and the third sealing cylinder 33 are contracted, and the slider 36 can squeeze the spring 373 to provide a buffer for the contraction of the positioning member 3. In the process of contraction of the positioning member 3, the inner rod 371 slides inside the outer rod 372 to provide a guiding function for the compression direction of the spring 373.

[0026] The working principle of the present invention is as follows: when sampling a wall or the ground, the handle 11 is manually gripped to press the positioning member 3 against the concrete. Since the positioning member 3 is retractable, when the positioning member 3 is manually pressed downward, the third sealing cylinder 33 slides toward the inside of the second sealing cylinder 32 through the slider 36, and the second sealing cylinder 32 is received into the inside of the first sealing cylinder 31 through the slider 36, thereby realizing the contraction of the positioning member 3 until the drill tube 52 is pressed against the surface of the concrete, and then the driving motor 51 is started to drive the drill tube 52 to rotate, and then the driving motor 51 is manually pressed downward to drive the drill tube 52 to move toward the inside of the concrete, thereby performing the sampling operation. During the sampling process of the drill tube 52 rotating, the first sealing cylinder 31, the second sealing cylinder 32 and the third sealing cylinder 33 can provide positioning for the moving direction of the drill tube 52, so that during the drilling process, the center line of the drill tube 52 is aligned with the first sealing cylinder 33. The center lines of the sealing cylinder 31, the second sealing cylinder 32 and the third sealing cylinder 33 are always on the same horizontal line, preventing the drill tube 52 from shifting during the sampling process and affecting the sampling effect, thereby ensuring the sampling quality of the device. The first sealing cylinder 31 and the second sealing cylinder 32 are fixedly installed with a sealing ring 34 at one end away from the mounting plate 1, so that a closed space can be formed between the first sealing cylinder 31, the second sealing cylinder 32 and the third sealing cylinder 33 and the wall or the ground, so that the drill tube 52 can drill in a closed space, so that the dust generated by the drill tube 52 during the sampling process will not spread to the outside, thereby improving the dustproof effect of the device. At the same time, the first sealing cylinder 31, the second sealing cylinder 32 and the third sealing cylinder 33 can be used to collect the dust generated during the sampling process, thereby reducing the subsequent cleaning work of the user, making it more convenient for people to use.
