[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] This utility model provides a portable PVC pipe cutter. Please refer to [link / reference]. Figures 1-4 The system includes a wooden mold 10, on which two sets of first square plates 20 are fixedly installed on each of the four sides by self-tapping screws. One end of the side of the first square plate 20 is rotatably connected to a second square plate 30 by a rotary bolt, and the other end of the side of the first square plate 20 is connected to the second square plate 30 by a snap-fit ​​assembly. A handle 11 is fixedly installed in the middle of the wooden mold 10 by glue to facilitate rotation of the wooden mold 10. A first semi-circular groove 21 is formed on the side of the first square plate 20 facing the second square plate 30, and a second semi-circular groove 21 is formed on the side of the second square plate 30 facing the first square plate 20. Two semi-circular grooves 31, and the first semi-circular groove 21 and the second semi-circular groove 31 form a circular hole that matches the diameter of the PVC pipe. A blade 22 is fixedly installed between the two sets of first square plates 20 by glue, and the sharp end of the blade 22 is located in the first semi-circular groove 21. The wooden mold 10 is square in shape and made of wood. The handle 11 is made of wood, and the blade 22 is made of stainless steel. The four sets of circular holes formed have different diameters, and the diameters are preferably 50mm, 75mm, 110mm, and 200mm, respectively.

[0026] The buckle assembly includes: a first notch 40, a positioning rod 41, a barb 42, a second notch 43, and a hook groove 44;

[0027] The second square plate 30 has a first notch 40 at the end away from the rotating bolt. The positioning rod 41 is rotatably connected to the first notch 40 by the rotating bolt. The barb 42 is integrally provided on the end of the positioning rod 41. The first square plate 20 has a second notch 43 at the end away from the rotating bolt, and the positioning rod 41 can be inserted into the second notch 43. The first square plate 20 has a hook groove 44 at the end away from the rotating bolt, and the hook groove 44 is connected to the second notch 43. The barb 42 is inserted into the hook groove 44.

[0028] In practical use, the specific operating steps for those skilled in the art are as follows:

[0029] According to the diameter of the PVC pipe, place the PVC pipe in the corresponding first semi-circular groove 21 and second semi-circular groove 31. Then, bring the first square plate 20 and the second square plate 30 into contact. After the first square plate 20 and the second square plate 30 are in contact, rotate the positioning rod 41 so that the positioning rod 41 is inserted into the second notch 43. When the positioning rod 41 is inserted into the second notch 43, its barb 42 will be inserted into the hook groove 44. At this point, the first square plate 20 and the second square plate 30 can be fixedly connected together. When the first square plate 20 and the second square plate 30 are fixed together, the sharp end of its blade 22 will pierce into the PVC pipe. Then, have a person hold the handle 11. After holding it, force can be applied to make the wooden mold 10 rotate around the PVC pipe as the center point. When the wooden mold 10 rotates around the PVC pipe as the center point, its blade 22 will also rotate around the PVC pipe as the center point. When the blade 22 rotates around the PVC pipe as the center point, the PVC pipe will be cut.
