[0025] The following gives specific embodiments.
[0026] Please refer to Figure 1 - Figure 5, the present utility model provides a core bit, including a first hollow bit 1; a mounting block 102 is fixedly connected to the top of the first hollow bit 1; a second hollow bit 101 is arranged on one side of the first hollow bit 1; connection blocks 103 are fixedly connected to the tops of both the first hollow bit 1 and the second hollow bit 101; a mounting stud 104 is threadedly connected to the surface of the connection block 103; a fixing nut 105 is threadedly connected to the surface of the mounting stud 104; tooth segments 106 are fixedly connected to the bottoms of both the first hollow bit 1 and the second hollow bit 101; a limiting clamping post 107 is fixedly connected to one side of the first hollow bit 1; a limiting clamping groove for cooperating with the limiting clamping post 107 is formed on one side of the second hollow bit 101; a sliding post 108 is slidably connected inside the first hollow bit 1 and the second hollow bit 101; a moving plate 109 is fixedly connected to one end of the sliding post 108; the moving plate 109 is slidably connected to the first hollow bit 1 and the second hollow bit 101; a reinforcing component is arranged at the bottom of the first hollow bit 1; the number of the tooth segments 106 is several; the tooth segments 106 are evenly distributed at the bottoms of the first hollow bit 1 and the second hollow bit 101; the number of the limiting clamping posts 107 is several; the number of the limiting clamping grooves is the same as that of the limiting clamping posts 107; the limiting clamping posts 107 are evenly distributed on one side of the first hollow bit 1; during operation, when coring, by rotating the blocking cap 5; making the blocking cap 5 disengage from the sliding post 108, the user rotates the fixing nut 105 to make the fixing nut 105 disengage from the mounting stud 104, then the user pushes the sliding post 108 to make the sliding post 108 disengage from the first hollow bit 1 and the second hollow bit 101, then the user disengages the reinforcing component and removes the second hollow bit 101, and then pushes the sliding post 108 again to push out and take out the object inside the core bit, thus facilitating the user to take out.
[0027] Further, as Figure 1 and Figure 5 shown, the reinforcing component includes a reinforcing plate 2; the bottom of the first hollow bit 1 is fixedly connected to the top of the reinforcing plate 2; a fixing stud 201 is threadedly connected to the surface of the reinforcing plate 2; the surface of the fixing stud 201 is threadedly connected to the bottom of the second hollow bit 101; during operation, by rotating the fixing stud 201, the reinforcing plate 2 is connected to the second hollow bit 101 to reinforce the connection between the first hollow bit 1 and the second hollow bit 101.
[0028] Further, as Figure 4As shown in the figure, a connecting and fixing block 301 is provided at the top of the moving plate 109; an arc-shaped cleaning scraper 302 is fixedly connected to one side of the fixing block 301; a limiting stud 3 is threadedly connected to the surface of the fixing block 301; the bottom of the limiting stud 3 is threadedly connected to the moving plate 109.

During operation, the moving plate 109 squeezes the reset buffer spring 4. After the core drill bit is taken out, under the action of the reset buffer spring 4, the moving plate 109 is reset and lifted, so that the object in the core drill bit is pushed out, thus assisting the user to take it out.
[0030] Further, as Figure 3 shown in the figure, a blocking cap 5 is threadedly connected to the top of the sliding column 108; the material of the blocking cap 5 is stainless steel. During operation, the sliding column 108 is blocked by the blocking cap 5, reducing the probability of the sliding column 108 detaching from the first hollow drill bit 1 and the second hollow drill bit 101 and reducing the impact on its operation.
[0031] Working principle: When taking a core, by rotating the blocking cap 5 to make the blocking cap 5 disengage from the sliding column 108, the user rotates the fixing nut 105 to make the fixing nut 105 disengage from the mounting stud 104. Then the user pushes the sliding column 108 to make the sliding column 108 disengage from the first hollow drill bit 1 and the second hollow drill bit 101. Then the user detaches the reinforcement assembly and removes the second hollow drill bit 101. Then the user pushes the sliding column 108 again to push out and take out the object in the core drill bit, thus facilitating the user to take it out. By rotating the fixing stud 201, the reinforcement plate 2 is connected to the second hollow drill bit 101 to reinforce the connection between the first hollow drill bit 1 and the second hollow drill bit 101. The moving plate 109 drives the arc-shaped cleaning scraper 302 to scrape and clean the inside of the first hollow drill bit 1 and the second hollow drill bit 101, reducing the residue of the core sample. The moving plate 109 squeezes the reset buffer spring 4. After the core drill bit is taken out, under the action of the reset buffer spring 4, the moving plate 109 is reset and lifted, so that the object in the core drill bit is pushed out, thus assisting the user to take it out. The sliding column 108 is blocked by the blocking cap 5, reducing the probability of the sliding column 108 detaching from the first hollow drill bit 1 and the second hollow drill bit 101 and reducing the impact on its operation.
