[0030] According to an embodiment of the utility model, a handheld pipe cutter for air-conditioning copper pipes is provided.

[0031] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figure 1-4 As shown, according to an embodiment of the utility model, a handheld pipe cutter for air-conditioning copper pipes comprises a support plate 1 and a cutting ring 9. An adjusting rod 5 is fixedly installed at the top position of the surface of one side of the support plate 1. The cutting ring 9 is slidably connected to the outer periphery of the adjusting rod 5. Positioning holes 6 are provided on the surface of the adjusting rod 5 and the surface of the cutting ring 9, and a fixing pin 8 is inserted in the inner position of the positioning hole 6. Several groups of positioning scales 7 are evenly engraved on the surface of the adjusting rod 5. A support rod 3 is welded to the middle position of the surface of the support plate 1. Several groups of cutting grooves 4 are evenly provided on the surface of the support rod 3. The cutting groove 4 is provided to provide a space for the cutting blade 12 to cut smoothly.

[0032] In one embodiment, a gear ring 16 is rotatably connected to the inside of the cutting ring 9, and a plurality of connecting seats 11 are evenly welded on the surface of one end of the gear ring 16. A cutting blade 12 is installed on the surface of the connecting seat 11. The other end of the gear ring 16 is meshingly connected to a driving gear 15. The driving gear 15 is located at the bottom end of the cutting ring 9. One end of the driving gear 15 passes through one side of the cutting ring 9 and is connected to a motor 13. The motor 13 is configured to provide power for the rotation of the driving gear 15.

[0033] In one embodiment, support legs 14 are symmetrically installed on both sides of the bottom of the support plate 1 and the bottom of the cutting ring 9. The support legs 14 can support and fix the device for subsequent use, which can effectively reduce the long-term holding time of personnel and reduce the labor intensity of personnel.

[0034] In one embodiment, a battery and a controller are disposed inside the support plate 1 and are electrically connected to the motor 13 via wires. The controller and the battery are common structures and thus will not be described in detail.

[0035] In one embodiment, the support plate 1 and the cutting ring 9 are both made of metal material, and the metal material ensures the strength of the structure.

[0036] In one embodiment, a driving groove 10 for installing the gear ring 16 is provided on the surface of the cutting ring 9 .

[0037] In one embodiment, a handle 2 is welded on one side of the support plate 1. The provision of the handle 2 facilitates personnel to hold the entire structure, and facilitates movement and subsequent use.

[0038] In one embodiment, the diameter of the support rod 3 is the same as the inner diameter of the air-conditioning copper tube. The size is set to ensure that the support rod 3 can support the air-conditioning copper tube after being inserted into it, thereby avoiding deformation of the tube during cutting and ensuring subsequent use effects.

[0039] Working principle: In actual use, personnel can move the cutting ring 9 according to the required cutting length, and accurately move it to the specified position through the positioning scale 7 on the surface, and then insert the positioning pin into the positioning hole 6 to fix it to avoid movement during subsequent cutting. Then the device can be placed on the ground through the support legs 14, and the air-conditioning copper tube is inserted into the outside of the support rod 3. At this time, the inside of the air-conditioning copper tube will be supported by the support rod 3, and then the motor 13 can drive the driving gear 15 to rotate, and the driving gear 15 can drive the gear ring 16 meshing with it to rotate. The rotation of the gear ring 16 can drive the cutting blade 12 on its surface to rotate along the air-conditioning copper tube to achieve the cutting operation. Since the two ends of the air-conditioning copper tube are supported by the support rod 3, the deformation of the copper tube during cutting can be effectively avoided, thereby ensuring the subsequent use effect. The device as a whole has the advantages of anti-flattening during cutting, high cutting accuracy, and double support for cutting.
