In this embodiment, the mounting frame 7 facilitates the rotation of the auxiliary cylinder 8, and the support bearing 10 reduces friction.
[0034] Reference Figure 4 , Figure 5 and Figure 6A support structure 11 is provided on the outer side of the mounting ring 1. The support structure 11 includes a support plate 12. A threaded cylinder 13 is provided inside the support plate 12. A threaded rod 14 is provided inside the threaded cylinder 13. A fixing nut 15 is provided on the outer side of the threaded rod 14. An internal hexagonal groove 16 and a ball groove 17 are provided inside the threaded rod 14. A connecting ball 18 is provided inside the ball groove 17. A connecting rod 19 is provided at the bottom of the connecting ball 18. A connecting plate 20 is provided at the bottom of the connecting rod 19. A positioning pin 21 is provided at the bottom of the connecting plate 20. In this embodiment, the support plate 12 serves as both the threaded cylinder 13 and the mounting ring. The threaded cylinder 13 facilitates the adjustment of the mounting ring 1.
[0035] Reference Figure 4 , Figure 5 and Figure 6 The support plate 12 is fixedly connected to the outside of the mounting ring 1, the threaded cylinder 13 is fixedly connected to the inside of the support plate 12, the threaded rod 14 is adapted to the threaded cylinder 13, and the fixing nut 15 is snapped onto the outside of the threaded rod 14. In this embodiment, the threaded rod 14 serves to facilitate the adjustment of the angle.
[0036] Reference Figure 4 , Figure 5 and Figure 6 The connecting ball 18 is rotatably connected to the inside of the ball groove 17, the connecting rod 19 is fixedly connected to the bottom of the connecting ball 18, the connecting plate 20 is fixedly connected to the bottom of the connecting rod 19, and the positioning pin 21 is fixedly connected to the bottom of the connecting plate 20. In this embodiment, the connecting ball 18 facilitates the rotation of the connecting plate 20, and the fixing pin 21 serves to clamp the material.
[0037] The implementation principle of this embodiment is as follows:
[0038] When drilling into materials with uneven surfaces, place the mounting ring 1 and other structures on the surface of the material and use a tool to snap it into the interior hexagonal slot 16. Then rotate the threaded rod 14. During the rotation of the threaded rod 14, the length of the threaded rod 14 on both sides of the threaded cylinder 13 can be changed by using the threaded engagement between the threaded rod 14 and the threaded cylinder 13, so as to adjust the angle of the mounting ring 1. When the mounting ring 1 is in a horizontal state, use a tool to rotate the fixing nut 15, so that the fixing nut 15 moves towards the threaded cylinder 13 and guides the fixing nut 15 to fit into the threaded cylinder 13. At this time, the fixing of the threaded rod 14 is completed, preventing the threaded rod 14 from shifting during use.
[0039] When the mounting ring 1 and other structures are placed on the material, the positioning pin 21 needs to be engaged inside the material. Since the surface of the material is irregularly inclined, the connecting ball 18 will rotate inside the ball groove 17, while the connecting plate 20 will be parallel to the surface of the material.
[0040] After adjusting the mounting ring 1 to a horizontal position, the drill rod is locked inside the auxiliary cylinder 8. Since the auxiliary cylinder 8 is equipped with a limit block 9, the drill rod can be locked inside the auxiliary cylinder.
[0041] After the drill rod is clamped inside the auxiliary cylinder 8, the equipment is started to drive the drill rod to rotate rapidly. During the rapid rotation of the drill rod, the operator can move the drill rod equipment. During the movement of the drill rod equipment, since the installation ring 1 has a guide hole 6 inside and the guide hole 6 is included on the outside of the guide rod 4, the installation ring 1 will slide on the outside of the guide rod 4. There are three guide rods 4, and each guide rod is T-shaped, which can effectively prevent the lifting ring 5 from tilting during the sliding process.
[0042] Compared with the prior art, the present invention has the following advantages:
[0043] The addition of mounting plate 3 serves to fix guide rod 4. The cooperation between guide rod 4 and guide hole 6 facilitates the up-and-down sliding of lifting ring 5. The cooperation between mounting bracket 7 and support bearing 10 facilitates the rotation of auxiliary cylinder 8. The addition of support bearing 10 reduces friction. The installation of limit block 9 inside auxiliary cylinder 8 facilitates the locking of drill rod. Using the above structure, the drill rod can be assisted to slide, thereby preventing the drilling from tilting. The internal hexagonal hole of threaded rod 14 facilitates the rotation of threaded rod 14. The cooperation between threaded rod 14 and threaded cylinder 13 facilitates the tilting angle of mounting ring 1. The cooperation between ball groove 17, connecting ball 18 and connecting rod 19 facilitates the tilting of connecting plate 20. The addition of positioning pin 21 at the bottom of connecting plate 20 provides positioning. The installation of fixing nut 15 on the outside of threaded rod 14 fixes threaded rod 14. Using the above structure, displacement during drilling can be effectively prevented.
