The interiors of the two cavities 2 are respectively fixedly connected with fixed columns 3, which increase the stability of the structure. The exterior of the fixed columns 3 is provided with a plurality of springs 4, which serve as shock-absorbing elements and can absorb and buffer the vibrations generated during the drilling process, thereby reducing noise. The exterior of the fixed columns 3 is slidably connected to two sliders 5, and the far sides of the two sliders 5 are respectively fixedly connected to two fixed blocks 6, which are connected to the sliders 5 to form a fine-tunable connection system. The interiors of the two fixed blocks 6 are rotatably connected with connecting rods 7, which are a connecting rod mechanism for transmitting force and movement. The right side of the connecting rod 7 is rotatably connected to two right side fixed blocks 6, and the right sides of the two right side connecting rods 7 are fixedly connected to movable blocks 8, and the right side of the movable blocks 8 are fixedly connected to protrusions 9. The protrusions 9 are used to limit or lock a certain component to ensure the stability of the mechanism. The interior of the guide cylinder 1 is provided with a plurality of openings 10, which are used for heat dissipation, exhaust, noise reduction or providing maintenance channels for internal mechanical components. The interior of the guide cylinder 1 is rotatably connected to a rotating shaft 11, and the bottom end of the rotating shaft 11 is fixedly connected to a drill bit 12. The rotating shaft 11 is the main shaft that drives the drill bit 12 to rotate. The outside of the guide cylinder 1 is fixedly connected to a reinforcement component for support.

[0032] Reference Figure 4 The reinforcement assembly includes two fixed rods 13, which ensure the stability of the entire power head. The bottom ends of the two fixed rods 13 are fixedly connected to a connecting plate 14, and the top ends of the connecting plates 14 are fixedly connected to an electric push rod 15. The connecting plate 14 provides a mounting base for the electric push rod 15, and also strengthens the connection between the fixed rods 13, thereby improving the overall rigidity. The output end of the electric push rod 15 is fixedly connected to a half-slip ring 17. The electric push rod 15 is used to apply force on the half-slip ring 17 to adjust or lock the position of certain mechanical components to adapt to different working conditions or reduce vibration. The interior of the two fixed rods 13 is respectively provided with a slide groove 16, which is used to guide and limit the movement path of certain components, or to facilitate maintenance and adjustment. The left sides of the two fixed rods 13 are fixedly connected to a fixed half ring 18, and the top ends of the two fixed rods 13 are respectively fixedly connected to a reinforcement rod 19. The fixed half ring 18 and the reinforcement rod 19 further enhance the structural strength of the entire reinforcement assembly. A support plate 20 is fixedly connected to the right side of the two reinforcement rods 19. This plate provides a wide connection surface for securing and supporting external interfaces 21, thereby enhancing the structural stability of the entire power head. Two external interfaces 21 are fixedly connected to the right side of the support plate 20. These interfaces are used to connect to external equipment or systems, such as hydraulic systems, electrical control systems, or other auxiliary equipment.

[0033] Reference Figure 2 、 Figure 3 、 Figure 4 , the outside of multiple movable blocks 8 are slidably connected to the inner wall of the guide cylinder 1, and the guide cylinder 1 allows the movable blocks 8 to adjust their positions within a certain range to adapt to different working conditions or reduce vibration and noise. The left and right sides of the two fixed columns 3 are fixedly connected to the outside of the uterine cavity 2 respectively. The fixed columns 3 help to disperse the force and improve the structural stability of the entire power head. The left side of the connecting rod 7 is rotatably connected to the inside of the left fixed block 6, and the right side of the connecting rod 7 is rotatably connected to the inside of the right fixed block 6. The connecting rod 7 and the fixed block 6 form a connecting rod mechanism that can transmit motion and force, which helps the efficient operation of the power head. The inside of the two sliders 5 are slidably connected to the outside of the fixed column 3 respectively. The slider 5 and the fixed column 3 cooperate to absorb impact and vibration, thereby reducing noise and improving the durability of the mechanism. The right side of the protrusion 9 contacts the outside of the rotating shaft 11. The protrusion 9 is used to transmit the noise and vibration generated when the rotating shaft 11 is working to the subsequent components. The adjacent sides of the two fixed rods 13 are respectively fixedly connected to the front and rear sides of the guide cylinder 1, and the outside of the fixed half ring 18 is in contact with the outside of the guide cylinder 1. The fixed rods 13 help to increase the rigidity and stability of the overall structure. The front and rear ends of the half slip ring 17 are respectively slidably connected to the outside of the two slide grooves 16. The slide grooves 16 allow the half slip ring 17 to adjust its position within a certain range to adapt to different working conditions or reduce vibration and noise. The bottom end of the electric push rod 15 is fixedly connected to the top of the connecting plate 14. The left inner side of the half slip ring 17 is in contact with the outside of the guide cylinder 1. The half slip ring 17 is used to stabilize the position of the guide cylinder 1 or reduce its vibration. The right sides of the two fixed rods 13 are fixedly connected to the left side of the support plate 20. The fixed rods 13 and the support plate 20 help to increase the rigidity and stability of the overall structure.

[0034] Working principle: When the device is in use, the rotating shaft 11 moves with the drill bit 12, and the rotating shaft 11 contacts the protrusion 9, so that the rotating shaft 11 will exert a force on the protrusion 9 during movement, so that the protrusion 9 moves with the movable block 8, and the movable block 8 rotates on the fixed block 6 with the connecting rod 7, so that the fixed block 6 drives the slider 5 to slide on the fixed column 3, and the connecting rod 7 is used to transfer the external force to the slider 5, and make the slider 5 compress the spring 4, thereby offsetting the noise generated by the device when in use and reducing the impact of the noise on the surrounding environment. At the same time, the staff can communicate more clearly, reduce the risk of misunderstandings and accidents, and thus improve construction efficiency.

[0035] When the device is continuously fixed, the electric push rod 15 slides with the half slip ring 17 in the slide groove 16 on the fixed rod 13, so that the half slip ring 17 is in close contact with the guide cylinder 1, thereby achieving the fixation of the device, keeping the device from being easily displaced during operation, and improving the rigidity of the entire machine, thereby maintaining the stability of the equipment and the drilling quality when facing complex formations. Strengthening the fixation can reduce the vibration of the power head during operation, thereby reducing structural fatigue and failure caused by vibration.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
