A spring 16 is sleeved on the outside of the guide rod 14 below the slider 15. A through hole adapted to the insertion rod 13 is opened on the top of the pressing cylinder 10. The setting of the connecting mechanism can drive the insertion rod 13 to move above the connecting plate 8 by synchronously pressing the two pressing cylinders 10 downward, so that the drill bit 6 can be disassembled. The operation is convenient and quick, and the drill bit 6 can be quickly disassembled and assembled, which is more efficient and more practical. In this example, the splash-proof component includes a limit frame 18, which is movably mounted on the outer side of the lower part of the box body 4. A protective cover 21 is movably mounted on the outer side of the limit frame 18 and above the limit frame 18 on the outer side of the box body 4.

[0024] The working principle of the utility model is as follows: when in use, the hydraulic cylinder 3 is started to push the box 4 downward, and the motor 5 is started to drive the drill bit 6 to rotate, so that the workpiece can be cut and processed. During the cutting process, the protective cover 21 cooperates with the base 1 to intercept the debris to prevent the debris from splashing and injuring the surrounding workers. As the drill bit 6 moves downward, the base 1 pushes the protective cover 21 to slide upward along the connecting rod 19, and the debris generated by the processing will fall through the gap on the grid plate 22 and be collected in the collection box 23; when the drill bit 6 needs to be removed and replaced, the two pressing cylinders 10 can be pressed downward synchronously, so that the tooth grooves on the inner wall of the pressing cylinder 10 will drive the tooth grooves with the pressing cylinder 10 to move downward. The meshing gear 12 drives the rotating shaft 11 to rotate, and then cooperates with the tooth groove 2 on the insertion rod 13, so that the gear 12 drives the insertion rod 13 to move upward, and the pressing cylinder 10 moves downward, which drives the slider 15 to slide along the guide rod 14 and squeeze the spring 16 until the lower end of the insertion rod 13 is moved above the connecting plate 8, and the connecting plate 8 and the drill bit 6 can be removed from the installation groove 24 to complete the removal of the drill bit 6; when installing the drill bit 6, the above steps can be repeated to move the lower end of the insertion rod 13 above the installation groove 24, and then after the connecting plate 8 and the drill bit 6 are installed in the installation groove 24, the pressing force applied to the pressing cylinder 10 is released, so that the slider 15 drives the guide rod 14 to slide along the guide rod 14 and squeeze the spring 16 under the elastic force of the spring 16. The pressing cylinder 10 is reset and moved upward, so that the tooth groove-driving gear 12 in the pressing cylinder 10 rotates in the opposite direction, thereby driving the insertion rod 13 to reset and move downward, so that the lower end of the insertion rod 13 passes through the connecting plate 8 and is inserted into the corresponding insertion hole, completing the limit fixation of the connecting plate 8, thereby completing the installation of the drill bit 6, making the disassembly and assembly operation of the drill bit 6 convenient, and the drill bit 6 can be quickly disassembled and replaced, and the work efficiency is higher; and when it is necessary to disassemble and replace the protective cover 21, the handle can be twisted to drive the connecting rod 19 to rotate, so that the connecting rod 19 is separated from the limit frame 18, and at the same time, the limit block 20 will be driven to move upward. When the lower end of the connecting rod 19 is separated from the limit frame 18, the limit frame 18 and The limit block 20 and the box body 4 are separated, and then the protective cover 21 can be removed; when installing the protective cover 21, the protective cover 21 is sleeved on the outer side of the lower part of the box body 4, and then the limit frame 18 is sleeved on the inner side of the protective cover 21 at the lower end of the box body 4, and then the lower end of the connecting rod 19 is passed through the protective cover 21, and at the same time, the lower end of the limit block 20 is inserted into the limit groove, and then the handle is twisted to drive the connecting rod 19 to rotate, so that the lower end of the connecting rod 19 is threadedly connected and fixed with the threaded groove on the limit frame 18, thereby connecting and fixing the limit block 20 and the limit frame 18 to the box body 4, completing the limiting of the protective cover 21. This structure can facilitate the replacement of the protective cover 21, is easy to use, and is more practical.
