[0030] Depend on Figure 1 A PE water supply pipe 21 cut-off device shown includes:

[0031] A positioning assembly is used to position the cutting position of the PE water supply pipe 21. The positioning assembly includes a clamp and a positioning plate 1. One end of the clamp is sleeved on the outside of the PE water supply pipe 21 and is detachably connected thereto. The other end of the clamp is fixedly connected to the positioning plate 1.

[0032] The fixing unit is used to assist in cutting off the PE water supply pipe 21. The fixing unit includes a connecting component. The two ends of the connecting component are respectively hinged with adjusting components. The adjusting component includes an adjusting plate 2. One end of the adjusting plate 2 is hinged with the connecting component. The other end of the adjusting plate 2 is hinged with a locking component. The side of the adjusting plate 2 is symmetrically rotated and connected with a first roller 3. The first roller 3 and the connecting component are respectively in rolling contact with the outer side of the PE water supply pipe 21. The end face of the first roller 3 is in sliding contact with one side of the positioning plate 1.

[0033] The cutting assembly is used to cut off the PE water supply pipe 21 . The cutting assembly passes through any one of the adjustment plates 2 and is disposed in contact with the outer side surface of the PE water supply pipe 21 .

[0034] Furthermore, a sliding roller 22 is embedded and rotatably connected to a side of the positioning plate 1 away from the clamp, and the sliding roller 22 is in sliding contact with the first roller 3, thereby reducing the guiding friction between the positioning plate 1 and the fixing unit and improving the rotation efficiency of the fixing unit.

[0035] Furthermore, the fixing unit is made of aluminum alloy, which can greatly reduce the weight of the device and improve the convenience of transferring the device.

[0036] To further optimize the solution, Figure 1 As shown, the clamp includes a conical sleeve 4, which is sleeved on the outside of the PE water supply pipe 21, and a gap is set between the inner side of the conical sleeve 4 and the outer side of the PE water supply pipe 21. One end of the conical sleeve 4 is provided with a plurality of clearance grooves 5, so that one end of the conical sleeve 4 is divided into a plurality of arc-shaped clamping pieces, one end of the conical sleeve 4 is screwed with a fastening sleeve 6 adapted thereto, and the other end of the conical sleeve 4 is fixedly connected to the positioning plate 1, and the PE water supply pipe 21 is respectively passed through the conical sleeve 4 and the positioning plate 1. The clamping piece at one end of the conical sleeve 4 is synchronously clamped to the PE water supply pipe 21 by rotating the fastening sleeve 6, so as to facilitate the positioning of the positioning plate 1.

[0037] To further optimize the solution, Figure 2-3 As shown, the connection assembly includes a connection plate 7, both ends of which are respectively hinged to one end of two adjustment plates 2, and both ends of the connection plate 7 are respectively symmetrically connected to second rollers 8, and the second rollers 8 are in rolling contact with the outer side of the PE water supply pipe 21. An extension plate 9 is hinged to one end of the connection plate 7, and one end of the extension plate 9 is hinged to one end of the adjustment plate 2. By adding the extension plate 9, the adaptability of the first roller 3 and the second roller 8 to the positioning of PE water supply pipes 21 with different pipe diameters can be improved.

[0038] To further optimize the solution, Figure 2 As shown, the locking assembly includes a hinged rod 10, one end of which is hinged to one end of the adjusting plate 2, and the other end of the hinged rod 10 is fixedly connected to a fixing column 11, and screws 12 are passed through and screwed at both end surfaces of the fixing column 11, and nuts 13 are screwed at both ends of the screw 12. By tightening the nuts 13 at both ends of the screw 12, the two fixing columns 11 can be pushed closer, thereby shortening the distance between the other ends of the two adjusting plates 2, thereby completing the covering of the outer side of the PE water supply pipe 21.

[0039] To further optimize the solution, Figure 4 As shown, the cutting assembly includes a fixed cylinder 14, which passes through the side of the adjustment plate 2 and is fixedly connected to the adjustment plate 2. The inner cavity of the fixed cylinder 14 is provided with a square hole, and a knife handle 15 is adapted and slidably connected in the square hole. One end of the knife handle 15 is fixedly connected to a flange 16, and the other end of the knife handle 15 is fixedly connected to a cutter head 17. The cutter head 17 is set to abut against the outer side of the PE water supply pipe 21. The cutter head 17 is an ordinary flat-head cutting knife, and its structure is a prior art and will not be repeated here. The top surface of the flange 16 is detachably connected to a push rod 18, and the side of the push rod 18 is screwed to the top of the inner cavity of the fixed cylinder 14. The push rod 18 can be used to adjust the feed size of the cutter head 17.

[0040] Furthermore, the end of the push rod 18 is a regular hexagonal end, which is convenient for screwing. This is a prior art and will not be described in detail here or shown in the drawings.

[0041] To further optimize the solution, a strong magnetic block 19 is embedded at one end of the push rod 18, and the handle 15 is detachably connected to the flange 16 via the strong magnetic block 19. The strong magnetic block 19 can adsorb the iron flange 16, which facilitates the maintenance and replacement of the cutter head 17.

[0042] As a further optimization scheme, a lever 20 is fixedly connected to one side of the adjustment plate 2, and a sleeve can be sleeved on the outer side of the lever 20 to increase the torque of the force applied and improve the cutting force of the cutter head 17 on the PE water supply pipe 21. The sleeve is a traditional force rod, which is a prior art and will not be described in detail here.

[0043] The working process of this embodiment is as follows:

[0044] The utility model is sleeved on the outside of one end of the PE water supply pipe 21, and the gap between the inner arc surfaces of the clamping pieces at one end of the conical sleeve 4 is reduced by tightening the fastening sleeve 6, and then the conical sleeve 4 is fitted and clamped with the PE water supply pipe 21. At this time, the position of the positioning plate 1 can be fixed, and then the fixing unit is sleeved on the outside of the PE water supply pipe 21. First, the two second rollers 8 of the connecting assembly are respectively fitted with the outside of the PE water supply pipe 21, and at the same time, the second rollers 8 are fitted with the side of the positioning plate 1 to maintain smooth sliding, and then the nuts 13 at both ends of the screw 12 are tightened to push the two fixing columns 11 closer, thereby shortening the distance between the other ends of the two adjustment plates 2. At this time, one end of the two adjustment plates 2 is close to each other, which will prompt the first roller 3 connected to the side of the adjustment plate 2 to contact with the PE water supply pipe 21, thereby completing the covering of the outer side of the PE water supply pipe 21.

[0045] Furthermore, it is necessary to ensure that at least one of the first rollers 3 of each adjusting plate 2 is in contact with the outer side surface of the PE water supply pipe 21 .

[0046] Insert the knife handle 15 into the square hole of the fixed tube 14. At this time, the knife head 17 fixedly connected to the bottom end of the knife handle 15 slides down and contacts the outer side of the PE water supply pipe 21. Rotate the push rod 18 to push the knife handle 15 downward for a certain amount of cutting, and stop rotating. Then use your hands or tools such as sleeves to insert it into the outside of the lever 20 and rotate it. At this time, the first roller 3 and the second roller 8 slide along one side of the positioning plate 1, and the knife head 17 eats into the outer wall of the PE water supply pipe 21, and the PE water supply pipe 21 is cut off layer by layer and cut through, thereby cutting off the PE water supply pipe 21.

[0047] The above are only preferred specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
