[0033] like Figures 1 to 5 As shown, the utility model provides a pipeline cutting auxiliary device, including a locking ring 100, a sliding seat 200, an arc-shaped rotating handle 300 and a cutting handle fixing seat 400. The locking ring 100 is used to be sleeved on the pipeline; the sliding seat 200 is slidably arranged on the outer ring of the locking ring 100, and the sliding seat 200 can slide along the circumference of the locking ring 100; the inner side of the arc-shaped rotating handle 300 is fixedly connected to the sliding seat 200; the cutting handle fixing seat 400 is slidably arranged on one side of the sliding seat 200, and the cutting handle fixing seat 400 can slide relative to the sliding seat 200 along the radial direction of the locking ring 100, and the cutting handle fixing seat 400 is provided with a cutting handle fixing hole 410, and the cutting handle fixing hole 410 is used to fix the cutting handle.

[0034] The pipe cutting auxiliary device provided by the utility model is used by sleeved the locking ring 100 on the pipe, the cutting handle is installed in the cutting handle fixing hole 410, and the arc-shaped rotating handle 300 is rotated to make the sliding seat 200 slide along the circumference of the locking ring 100, and the sliding seat 200 drives the cutting handle fixing seat 400 to move relative to the circumference of the pipe, so that the cutting handle can flexibly cut the pipe close to the wall and the ground completely, ensuring that the incision surface is smooth and flat, reducing repeated trimming of the incision after the pipe is cut, shortening the maintenance time, and reducing the maintenance cost, and the cutting handle fixing seat 400 can slide relative to the sliding seat 200 along the radial direction of the locking ring 100, and by sliding the cutting handle fixing seat 400 close to or away from the pipe, the depth of the cutting operation surface of the cutting handle can be adjusted, which can meet the cutting requirements of pipes of different thicknesses.

[0035] In some embodiments, the locking ring 100 includes a first locking half ring 110 and a second locking half ring 120, wherein a first connecting portion 111 is provided at one end of the first locking half ring 110, and a first locking portion 112 is provided at the other end of the first locking half ring 110, and the first locking portion 112 is provided with a first circular hole; a second connecting portion 121 is provided at one end of the second locking half ring 120, and the second connecting portion 121 is rotatably connected to the first connecting portion 111, and a second locking portion 122 is provided at the other end of the second locking half ring 120, and the second locking portion 122 is provided with a second circular hole aligned with the first circular hole, and the locking bolt 130 passes through the first circular hole and the second circular hole and is threadedly connected to the locking nut 140. When the locking ring 100 is put on the pipe, first buckle the first locking half ring 110 on the pipe, then rotate the second locking half ring 120 until it is buckled on the pipe, and then pass the locking bolt 130 through the first circular hole and the second circular hole to be threadedly connected with the locking nut 140, and tighten the locking nut 140 so that the first locking half ring 110 and the second locking half ring 120 firmly clamp the pipe.

[0036] Specifically, the radius of the first locking half ring 110 is the same as the radius of the second locking half ring 120, and the width of the first locking half ring 110 is the same as the width of the second locking half ring 120, so that the sliding seat 200 can slide relative to the locking ring 100. The first connecting portion 111 is provided with a first connecting hole, and the second connecting portion 121 is provided with a second connecting hole. The rotating shaft 150 is rotatably penetrated through the first connecting hole and the second connecting hole, so as to realize the rotatable connection between the first connecting portion 111 and the second connecting portion 121.
