[0024] In this embodiment, the drill body 2 is controlled to insert the square rod 3 into the square hole so that the top of the square rod 3 is against the top of the square hole. At this time, the ring 8 is slid downward to make the ring 8 slide on the wedge block 6 and squeeze the wedge block 6. At the same time, the sliding rod 5 pushes the clamping block 4 to move into the clamping groove. The square rod 3 can be clamped in the square hole by the clamping block 4. The ring 8 can be limited by the limiting assembly. Therefore, when the drill body 2 is used, the possibility of excessive movement of the ring 8 can be reduced. The wedge block 6 and the clamping block 4 are reset, making it impossible for the square rod 3 to fall off, thereby making the drill body 2 more stably installed. When disassembly is required, the limit assembly is opened, and the ring 8 is slid on the connecting rod 1 in the direction away from the drill body 2, so that the ring 8 and the wedge block 6 are no longer in contact, and the wedge block 6 and the clamping block 4 are reset by the first spring 7, so that the clamping block 4 is out of the slot, so the drill body 2 can be easily disassembled, thereby providing a geological drilling drill bit installation structure that can be easily and quickly disassembled and installed.
[0025] See also Figure 1-Figure 5The limiting assembly includes four groups of first limiting plates 9, limiting columns 10 and second springs 11. The four groups of first limiting plates 9 are symmetrically installed on the connecting rod 1. The bottom end of the collar 8 fits with the four groups of first limiting plates 9. A third groove is provided on the connecting rod 1. The limiting column 10 is slidably connected with the third groove. The limiting column 10 and the collar 8 are slidably fitted. The third groove is connected to a fourth groove. The two ends of the second spring 11 are respectively connected with the fourth groove and the limiting column 10. When the collar 8 slides downward, the collar 8 can be pressed against the first limiting plate 9 to reduce excessive sliding of the collar 8 toward the drill body 2. The movement reduces the possibility of the collar 8 and the wedge block 6 being separated. When the collar 8 slides downward, the inner wall of the collar 8 slides and fits with the limiting column 10. When the collar 8 contacts the first limiting plate 9, the limiting column 10 is separated from the inner wall of the collar 8, so that the limiting column 10 is pushed out a certain distance by the second spring 11. The collar 8 is limited by the limiting column 10, so that when the drill body 2 is in use, the collar 8 cannot move upward smoothly. When the collar 8 needs to be slid upward, it is only necessary to press the limiting column 10 completely into the third groove first, and then slide the collar 8.
[0026] See also Figure 2 , Figure 3 and Figure 5 , four groups of arcuate surfaces 12 are arranged on the clamping block 4; when the square rod 3 is not against the square hole, and the top end of the square rod 3 is not far away from the top end of the square hole, the square rod 3 can be driven to reach the specified position through the sliding between the arcuate surface 12 and the clamping slot, so that the clamping block 4 is clamped with the clamping slot to realize the installation and fixation of the square rod 3.
[0027] See also Figure 2 , Figure 3 , Figure 4 and Figure 5 , and also includes a second limiting plate 13, the second limiting plate 13 is connected to the limiting column 10, and the second limiting plate 13 is slidably clamped with the fourth groove; the second limiting plate 13 can reduce the possibility of the limiting column 10 being separated from the third groove.
[0028] See also Figure 2 , Figure 3 , Figure 4 and Figure 5 , two sets of inclined surfaces 14 are provided on the limiting column 10; by providing the inclined surface 14 on the limiting column 10, when the sliding collar 8 is in progress, the limiting column 10 does not need to be fully pressed into the third groove in advance to slide the collar 8.
[0029] See also Figure 1 , Figure 3 and Figure 4, and also includes two groups of handles 15. Two groups of card holes are set on the ring 8, and the two groups of handles 15 are respectively carded with the two groups of card holes; the two groups of handles 15 are convenient for sliding the ring 8 up and down, and the card holes are convenient for disassembly and assembly of the handles 15.
[0030] See also Figure 1 , Figure 3 and Figure 4 , both sets of handles 15 are provided with multiple sets of anti-skid ribs 16 , and the multiple sets of anti-skid ribs 16 are used for anti-skid; by providing the anti-skid ribs 16 on the handles 15 , the possibility of slipping can be reduced.
[0031] In summary, when the geological drilling drill bit installation structure is in use, the drill bit body 2 is controlled to insert the square rod 3 into the square hole, so that the top of the square rod 3 is against the top of the square hole. At this time, the ring 8 is slid downward to make the ring 8 slide on the wedge block 6 and squeeze the wedge block 6. At the same time, the sliding rod 5 pushes the block 4 to move into the slot. The square rod 3 can be clamped in the square hole by the block 4, and the ring 8 can be limited by the limiting assembly. Therefore, the ring can be lowered when the drill bit body 2 is used. 8 is less likely to move too much, thereby reducing the possibility of the wedge block 6 and the block 4 being reset when the drill body 2 is in use, so that the possibility of the square rod 3 falling off can be reduced, thereby making the drill body 2 more stably installed. When it is necessary to disassemble, by opening the limit assembly, the ring 8 is slid on the connecting rod 1 in the direction away from the drill body 2, and the ring 8 is no longer in contact with the wedge block 6, and the wedge block 6 and the block 4 are reset by the first spring 7, so that the block 4 is out of the slot, so the drill body 2 can be easily disassembled.

The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
