A toothed ring sleeve 12 is installed at the bottom of the limiting rotating ring 11. A toothed ring is provided at the lower part of the toothed ring sleeve 12, meshing with the gear 13. The lower left side of the top seat 2 is... The device is equipped with a drive box 14, which is connected to the drive cavity. A drive gear 15 is rotatably installed inside the drive box 14. The input end of the drive gear 15 is connected to the output end of the drive motor 16. The drive gear 15 meshes with the outer edge of the toothed ring sleeve 12. The outer wall of the arc-shaped support plate 8 is movably connected to both ends of the X-shaped push rod 7. Multiple support frames 9 are fixedly installed on the arc-shaped support plate 8. Guide support wheels 10 are rotatably installed on the support frames 9. Multiple support arms 18 are axially rotatably installed at the bottom of the fixed cylinder 1 through the rotating seat 17. The lower end of the support arm 18 is rotatably installed with a guide clamping wheel 21 through the rotating shaft 20. A spring 19 is fixedly installed at the top of the middle part of the support arm 18. The top of the spring 19 is fixedly connected to the bottom of the fixed cylinder 1. Limiting grooves are symmetrically opened at the front and rear ends of the adjustment groove of the fixed cylinder 1. Guide sliders 6 are fixedly installed at the front and rear ends of the push block 5. The guide sliders 6 are slidably installed in the limiting grooves.

[0019] The drive motor 16 is started, driving the drive gear 15 to rotate. The drive gear 15 drives the gear ring sleeve 12 to rotate, which in turn drives multiple gears 13 to rotate. These gears 13 then drive the rotating rod 3 to rotate. As the gear ring sleeve 12 rotates, it causes the limiting rotating ring 11 to rotate within the annular rotating groove, guiding and limiting the gear ring sleeve 12 to ensure stability.

The distance between the multiple support arms 18 can be adjusted by the rotating seat 17 and the spring 19, which is suitable for drill rods of different sizes. The drive motor 16 is started to drive the drive gear 15 to rotate, which drives the gear ring sleeve 12 to rotate, causing the gear ring sleeve 12 to drive multiple gears 13 to rotate, which in turn drives the rotating rod 3 to rotate. When the rotating rod 3 rotates, it can push the push block 5 to move in the adjustment groove through the threaded groove. The movement of the push block 5 in the adjustment groove drives the guide slider 6 to move in the limit groove, which guides and limits the push block 5.
