[0012] As a further improvement of this utility model, the support frame is fixedly connected to the side support rod.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] After the pipe to be cut is fitted onto the outside of the support mechanism, the two tool mounting brackets above the adjustable bracket are adjusted according to the reading of the scale. Then, the cutting tool is slidably positioned closer to the pipe by the sliding guide block on the tool mounting bracket. This allows for easy control of the cutting size.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] like Figure 1-5 As shown, this embodiment provides a pipe end cutting device, including a cutting mechanism 1. The cutting mechanism 1 includes: an adjustable bracket 2, a cutting blade 3, and a support mechanism 4. The support mechanism 4 includes: a threaded rod 401, a pipe support pad 402, and a side support rod 406. The pipe support pad 402 is movably connected to the threaded rod 401. Support screws 403 are arrayed on the outer side of the pipe support pad 402, and the support screws 403 are meshed and rotatably connected to the pipe support pad 402. Positioning nuts 404 are installed on both sides of the pipe support pad 402 outside the threaded rod 401 for positioning. Nut 404 is engaged and rotatably connected to threaded rod 401. A scale 201 is provided on the upper surface of the adjusting bracket 2. A tool mounting bracket 301 is installed below the cutting tool 3 on the outside of the adjusting bracket 2. A sliding guide block 302 is installed on the upper surface of the tool mounting bracket 301. The cutting tool 3 is slidably connected to the sliding guide block 302. The tool mounting bracket 301 is slidably set with the adjusting bracket 2. A positioning bolt 303 is installed on the lower surface of the tool mounting bracket 301. The positioning bolt 303 is engaged and rotatably connected to the tool mounting bracket 301. The tool mounting bracket 301 is a U-shaped structural component.
[0024] like Figure 2-3 As shown, in this embodiment, threaded rod mounting pads 405 are installed at both ends of the threaded rod 401. A rotating bearing 408 is installed on the outer end of the threaded rod mounting pad 405. The rotating bearing 408 is fixedly connected to the threaded rod mounting pad 405. An movable groove 407 is opened on the inner wall of the side support rod 406 on the outer side of the rotating bearing 408. A support frame 6 is installed on the lower surface of the side support rod 406. The support frame 6 is fixedly connected to the side support rod 406. A pipe 5 to be cut is provided on the outer side of the support mechanism 4.
[0025] The working principle of this utility model is as follows: In use, firstly, two positioning nuts 404 are installed at both ends of the threaded rod 401 according to the overall length of the pipe 5 to be cut. Then, the pipe support pad 402 is fitted onto the outside of the threaded rod 401. Next, another positioning nut 404 is installed to clamp and fix the pipe support pad 402. Then, the pipe 5 to be cut is fitted onto the outside of the support mechanism 4. The pipe 5 is positioned by rotating the support screw 403. Finally, the rotating bearing 408 at the end of the threaded rod mounting pad 405 is inserted into the movable groove 407 inside the side support rod 406. The required pipe length is then controlled within the adjustable distance. After adjusting the position of the two tool mounting brackets 301 above the bracket 2 according to the reading of the scale 201, the positioning bolts 303 at the bottom of the tool mounting bracket 301 are rotated and positioned. Then, the sliding guide block 302 on the tool mounting bracket 301 is controlled to slide and position the cutting tool 3 closer to the pipe 5 to be cut. The support mechanism 4 is controlled to rotate inside the movable groove 407 using the rotating bearing 408. The pipe 5 to be cut is rotated and contacts the cutting tool 3 to cut the unevenness at the end of the pipe 5. At the same time, by controlling the two cutting tools 3 to be installed in different positions above the adjustable bracket 2, the pipe 5 to be cut above can be cut in multiple segments.
