[0044] Optionally, as shown in the figure, Figure 1As shown, the fixing tool of the oil drill bit further comprises a buffer protection piece 6. The buffer protection piece 6 is arranged in the first mounting groove 13. When the oil drill bit is clamped and fixed, the buffer protection piece 6 is in contact with the outer wall of the oil drill bit, which can improve the fixing effect of the oil drill bit, prevent the oil drill bit from shaking and moving, and absorb part of the impact energy when the fixing tool is impacted or vibrated from outside, so as to reduce the damage to the oil drill bit and protect the oil drill bit from or reduce the damage caused by impact or extrusion.

The buffer air bag 61 is arranged in the first mounting groove 13, and one end of the connecting air pipe 62 is in communication with the buffer air bag 61 and the other end is configured to be in communication with the air pump. The air pump fills the buffer air bag 61 with gas through the connecting air pipe 62 to make the buffer air bag 61 expand and tightly abut against the oil drill bit. When the oil drill bit is tightened by the tightening assembly 2, the air pump can be controlled to fill the buffer air bag 61 with gas through the connecting air pipe 62 to make the buffer air bag 61 expand, so as to further abut against the oil drill bit and prevent the oil drill bit from shaking, thereby improving the clamping and fixing effect.

[0046] Optionally, as shown in the drawings, Figure 1 and Figure 3 The tightening assembly 2 comprises a tightening piece 21, a first magnet 22, a second magnet 23 and a reset piece 24. The tightening piece 21 is arranged in the mounting chamber 7, the first magnet 22 is arranged on the bottom wall of the mounting chamber 7, the second magnet 23 is arranged on the side of the tightening piece 21 away from the containing chamber and opposite to the first magnet 22, and one end of the reset piece 24 is connected to the bottom wall of the tightening piece 21 and the other end is connected to the bottom wall of the mounting chamber 7. The first magnet 22 is an electromagnet, and the first magnet 22 and the second magnet 23 have a mutual approaching state and a mutual moving away state, so that the second magnet 23 drives the tightening piece 21 to move radially. When the mutual moving away state, the electromagnet is configured to be connected to the power supply.

[0047] When the oil drill bit needs to be tightened, the electromagnet is connected to the power supply, so that a magnetic field is generated around the electromagnet, the first magnet 22 generates a repulsive force on the second magnet 23, the second magnet 23 moves away from the first magnet 22, and at this time the second magnet 23 drives the tightening piece 21 to move radially, so that the tightening piece 21 can abut against the outer wall of the oil drill bit, and at the same time the reset piece 24 is deformed and elongated under the driving of the tightening piece 21. When the oil drill bit needs to be taken out, the electromagnet is disconnected, at this time the repulsive force between the first magnet 22 and the second magnet 23 disappears, the reset piece 24 drives the tightening piece 21 to move radially and away from the oil drill bit, so as to release the oil drill bit and facilitate taking out.

[0048] Exemplarily, the reset piece 24 comprises a spring.

[0049] Optionally, as shown in Figure 1 and Figure 3 The top pressing assembly 2 further comprises a top pressing roller 25. The top pressing roller 25 is rotatably arranged on the side of the top pressing piece 21 facing the accommodating chamber. When the oil drill bit needs to be pressed, the top pressing roller 25 is driven by the top pressing piece 21 to move along the radial direction under the action of the first magnet 22 and the second magnet 23, so that the top pressing roller 25 gradually approaches the oil drill bit until the top pressing roller 25 abuts against the outer wall of the oil drill bit. By arranging the top pressing roller 25, rolling contact with the oil drill bit can be realized, so as to reduce the abrasion of the outer wall of the oil drill bit and prevent damage thereof.

[0050] Exemplarily, the top pressing roller 25 comprises a rubber roller or the like.

The guide rod 26 is arranged in the mounting chamber 7 and extends along the radial direction of the accommodating chamber. The top pressing piece 21 is provided with a connecting through hole, and the guide rod 26 is arranged in the connecting through hole. When the top pressing piece 21 moves along the radial direction, it will simultaneously move along the axial direction of the guide rod 26 through the connecting through hole. By arranging the guide rod 26 and the connecting channel to cooperate with each other, the guide rod 26 can provide a guide function for the top pressing piece 21, so as to improve the movement accuracy of the top pressing piece 21, prevent deviation of the top pressing piece 21, and ensure the pressing effect on the oil drill bit.

[0052] Optionally, the inner wall of the connecting through hole is provided with a connecting protrusion. The outer wall of the guide rod 26 is recessed with a sliding groove extending along the axial direction of the guide rod 26, and the connecting protrusion is slidably arranged in the sliding groove. When the top pressing piece 21 moves along the radial direction, the connecting protrusion slides along the sliding groove of the guide rod 26. By arranging the connecting protrusion and the sliding groove to cooperate with each other, the top pressing piece 21 can be further limited, so as to prevent the top pressing piece 21 from being inclined and displaced, thereby ensuring that the top pressing piece 21 is pressed along the radial direction to the outer wall of the oil drill bit and ensuring the clamping and fixing effect on the oil drill bit.
