[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3This utility model provides a technical solution: a grinding device for the head of a live sampling forceps, including a connecting frame 1, an inclined block 2 installed on the inner wall of the bottom of the connecting frame 1, a triangular blocking groove on the right side of the inclined block 2 to prevent debris from spilling out when the connecting frame 1 is tilted, a blocking layer 3 slidably connected inside the connecting frame 1, a fixing plate 4 provided inside the connecting frame 1, connecting strips 5 installed on the inner sides of the blocking layer 3 and the fixing plate 4, an auxiliary fan 6 (model FAG-400F) passing through the inside of the fixing plate 4, and a fixing pin 7 passing through the outer side of the connecting frame 1, with one end of the fixing pin 7 passing through the inside of the connecting frame 1. Inserted into the fixing plate 4, a plug-in rod 8 is inserted through the left side of the connecting frame 1. A transparent shell 9 is installed at the left end of the plug-in rod 8. Connecting posts 10 are installed on the outer sides of both the transparent shell 9 and the connecting frame 1. A fixing frame 11 is sleeved on the outer surface of the connecting post 10 on the right side. A buffer spring 12 is installed inside the fixing frame 11. The rebound of the buffer spring 12 causes the moving post 13 to move to the right along the fixing frame 11, which in turn causes the transparent shell 9 to move to the right, thereby moving the plug-in rod 8 to the right. After the plug-in rod 8 moves to the right, it is inserted into the connecting frame 1. This makes it easier for the components inside the device to protect the operator and prevent the breakage of the components during the grinding process. The device's safety during operation is improved by minimizing the risk of debris splashing onto people. This further enhances the effectiveness of its internal components. A movable column 13 is slidably connected inside the fixed frame 11. The left end of the buffer spring 12 is mounted on the right side of the movable column 13. The left side of the movable column 13 is sleeved onto the outer surface of the connecting column 10 located on the left side. A connecting piece 14 is installed inside the connecting frame 1, and a transmission rod 15 is rotatably connected inside the connecting piece 14. A grinding disc 16 is mounted on the left end of the transmission rod 15. A drive motor 17, model Y80M1-2, is mounted on the right side of the connecting piece 14. The drive motor 17 is started, causing the drive rod 15 to rotate and drive the grinding disc 16 to rotate to grind the workpiece. Then, the output end of the auxiliary fan 6 rotates and draws air in through the placement slot, which makes it easier for the operator to operate the components inside the device to collect the debris. This shortens the time required for the operator to operate the components inside the device to collect debris, reduces the impact of debris accumulation on the operator's normal grinding, and further improves the operator's work efficiency in the process of operating the components inside the device to collect debris. The output end of the drive motor 17 is keyed to the right end of the drive rod 15, and the outer side of the transparent shell 9 is provided with a placement slot.

[0022] In this utility model, to make the device more stable, a threaded hole is provided on the outer side of the fixing plate 4, and an external thread is provided on the outer surface of the fixing pin 7. The fixing pin 7 is threadedly connected to the fixing plate 4. A sliding groove is provided inside the connecting frame 1. The fixing plate 4 is a square sliding plate. The fixing plate 4 is slidably connected to the connecting frame 1. A round hole is provided on the outer side of the connecting frame 1. The size of the round hole is adapted to the size of the fixing pin 7. A blocking mesh is fixedly connected inside the blocking layer 3. The blocking mesh is made of polytetrafluoroethylene material to prevent the parts from becoming loose.

[0023] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0024] In use, the fixed plate 4 is slid in along the connecting frame 1, allowing the blocking layer 3 to extend into the connecting frame 1. The fixed pin 7 is inserted into the fixed plate 4 through the connecting frame 1, and then rotated clockwise to fix the fixed plate 4 in the connecting frame 1. The transparent shell 9 is moved to the left, causing the insertion rod 8 to move to the left and be pulled out of the connecting frame 1. The transparent shell 9 moves to the left, causing the moving column 13 to move to the left. The moving column 13 moves to the left along the fixed frame 11, stretching the buffer spring 12. The transparent shell 9 is then opened outward, causing the fixed frame 11 to flip along the connecting column 10 on the right side, allowing the fixed workpiece to be inserted into the placement slot. The transparent shell 9 is then flipped inward to close it. The transparent shell 9 is then released, allowing... The buffer spring 12 rebounds, causing the moving column 13 to move to the right along the fixed frame 11. The moving column 13 moves to the right, causing the transparent shell 9 to move to the right. The transparent shell 9 moves to the right, causing the plug rod 8 to move to the right. The plug rod 8 moves to the right and inserts into the connecting frame 1. The drive motor 17 is started. The output end of the drive motor 17 rotates, causing the drive rod 15 to rotate. The rotation of the drive rod 15 causes the grinding disc 16 to rotate. The grinding disc 16 rotates to grind the workpiece. The auxiliary fan 6 is started. The output end of the auxiliary fan 6 rotates and draws in air through the placement slot. The air enters the connecting frame 1 along the inclined block 2. The air passes through the blocking layer 3 to block the debris it carries. The air is discharged along the auxiliary fan 6.

[0025] In summary, the grinding device for the live sampling forceps head, through the rebound of the buffer spring 12, drives the moving column 13 to move to the right along the fixed frame 11, causing the transparent shell 9 to move to the right, which in turn drives the insertion rod 8 to move to the right. The insertion rod 8 then moves to the right and inserts into the connecting frame 1, thus making it easier for the components inside the device to protect the operator. This prevents debris from splashing onto the operator during the grinding process, improving the safety of the device during use and further enhancing the effectiveness of the components inside the device during operation.

[0026] The grinding device of the live sampling forceps head, by starting the drive motor 17, causes the drive rod 15 to rotate, which drives the grinding disc 16 to rotate and grind the workpiece. Then, the output end of the auxiliary fan 6 rotates and draws air in through the placement slot, which makes it easier for the operator to operate the internal parts of the device to collect the debris. This shortens the time required for the operator to operate the internal parts of the device to collect debris, reduces the impact of debris accumulation on the operator's normal grinding, and further improves the operator's work efficiency in the process of operating the internal parts of the device to collect debris.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
