[0033] In order to improve the stability of the first positioning rod 41, please refer to Figure 1 In a preferred embodiment, the first positioning rod 41 is inclined at 30 degrees toward the side close to the bent section 31 of the curved pipe 3.

[0034] During use, when the first positioning rod 41 abuts against the side of the curved section 31 of the curved pipe 3 away from the drilling machine 12 , a downward pressure is applied to the curved section 31 of the curved pipe 3 , making the fixation more stable.

[0035] In order to facilitate the installation and removal of the first positioning rod 41, please refer to Figure 2 In a preferred embodiment, a base plate 13 is fixedly connected to the frame 11 on one side of the first support rod 21, and a positioning groove 14 for accommodating the first positioning rod 41 is provided on the base plate 13. A socket 15 is provided on one side of the base plate 13, and an insertion rod 16 is slidably inserted into the socket 15. A slot for accommodating the insertion rod 16 is provided at the bottom end of the first positioning rod 41.

[0036] During use, the first positioning rod 41 is easily worn by the impact of the drilling machine 12 and needs to be replaced regularly to ensure drilling accuracy. When installing the first positioning rod 41, slide the first positioning rod 41 into the positioning groove 14, align the socket 15 with the slot, slide the insertion rod 16 into the socket 15 and the slot, and the first positioning rod 41 is fixed.

[0038] During use, after first positioning rod 41 is slid into positioning slot 14 and insertion hole 15 is aligned with slot, rod 16 automatically rebounds into insertion hole 15 and slot under the restoring force of spring 17, making operation more convenient. Furthermore, under the restoring force of spring 17, rod 16 is firmly pressed against insertion hole 15 and slot, making it less likely to come loose and more secure.

[0039] To drill holes at different locations on the elbow 3, please refer to Figure 3 In a preferred embodiment, the second positioning rod 42 is slidably connected to the frame 11 , and the frame 11 is provided with an adjustment component 5 for adjusting the position of the second positioning rod 42 .

[0040] When in use, the position of the second positioning rod 42 can be adjusted using the adjustment component 5 according to the processing requirements of the drilling position, thereby adjusting the angle of the elbow 3, which has a wide range of applications and strong practicality.

[0041] To adjust the position of the second positioning rod 42, please refer to Figure 3 In a preferred embodiment, the adjustment assembly 5 includes a screw rod 51 rotatably connected to the frame 11 , the screw rod 51 is parallel to the second support rod 22 , and the screw rod 51 passes through the second positioning rod 42 and is threadedly connected to the second positioning rod 42 .

[0042] When in use, the screw rod 51 is rotated, and the screw rod 51 drives the second positioning rod 42 to slide, thereby adjusting the position of the second positioning rod 42. Not only is the adjustment convenient, but the screw rod 51 also has a self-locking function and a simple structure.

[0043] To facilitate the rotation of the screw 51, please refer to Figure 3 In a preferred embodiment, the end of the screw rod 51 is fixedly connected to a handle 52.

[0044] When in use, gripping the handle 52 and rotating the screw rod 51 reduces the possibility of slipping and makes the operation more convenient.

[0045] To reduce the possibility of screw 51 rotating loose, please refer to Figure 3In a preferred embodiment, a locking tooth ring 53 is coaxially fixedly connected to the screw rod 51, and a slot 54 is provided on the frame 11. A locking tooth block 55 engaged with the locking tooth ring 53 is clamped in the slot 54.

[0046] During use, after adjusting the second positioning rod 42 to a predetermined position, the anti-loosening tooth block 55 is inserted into the card slot 54, and the anti-loosening tooth block 55 is engaged with the anti-loosening tooth ring 53. Under the limiting action of the anti-loosening tooth block 55 and the anti-loosening tooth ring 53, the possibility of the screw rod 51 rotating and loosening is reduced, making the position of the second positioning rod 42 more accurate.
