[0004] After the cutting is completed, the insulated pipe cutting device of the above patent needs to manually remove the cut material from the inside of the device. Long pipes cannot be cut continuously and the clamping position needs to be continuously adjusted, which affects the cutting efficiency of long pipes. Utility Model Content
[0005] The purpose of the utility model is to provide an air-conditioning insulation PE pipe cutting device. Through the transmission of the threaded rod and the support of the connecting frame, the roller can extend out of the storage groove, extend out and contact the cut pipe, and the rotation of the roller can facilitate the user to directly extract the pipe, so that the pipe can be taken out from the inside of the device, avoiding the reciprocating movement of the clamping piece to adjust the clamping position, thereby solving the problems raised in the above-mentioned background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an air-conditioning insulation PE pipe cutting device, comprising a bracket, a first hydraulic telescopic rod is fixedly connected to the middle position of the bracket by bolts, a cutting blade is arranged at the lower end of the outside of the first hydraulic telescopic rod, a pair of clamping plates are arranged on both sides of the lower end of the cutting blade, storage grooves for storage are arranged at the upper and lower ends of the clamping plates, rollers are arranged inside the storage grooves, a connecting frame is arranged inside the storage grooves facing the rollers, an inner connecting pipe is welded to one end of the connecting frame, and a threaded rod is arranged on the outside of the inner connecting pipe.
[0007] Preferably, a connecting piece for connection is provided between each pair of the clamping pieces, and a second hydraulic telescopic rod for clamping is provided between the connecting piece and the clamping piece.
[0008] Preferably, the interior of the connecting frame is rotatably connected to the exterior of the roller, and the exterior of the threaded rod is matched with the internal thread of the inner connecting tube.
[0009] Preferably, a first connecting block is welded to one end of the second hydraulic telescopic rod facing the clamping piece, and a second connecting block is welded to one end of the clamping piece facing the first connecting block.

[0010] Preferably, a spring is provided inside the movable cavity.
[0011] Preferably, an external connecting tube for wrapping is provided on the outside of the internal connecting tube, and sliding rails for restriction are provided at the upper and lower ends of the external connecting tube and the inside of the movable cavity, and sliding bars are provided inside the sliding rails, and the sliding bars are connected to the sliding rail slots, and the sliding bars are welded and fixed to the corresponding second connecting block and the internal connecting tube.
[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0013] 1. In the utility model, after both sides of the pipe are clamped by the clamping pieces and the cutting blade contacts and completes the cutting, the threaded rod inside the storage groove rotates clockwise. The rotation of the threaded rod and the restriction of the sliding rail on the sliding bar can make the roller extend out of the storage groove. After extending and contacting the pipe, the cut pipe can be directly manually pulled out to avoid frequent extension and contraction of the clamping piece and complete the clamping and unfolding. After manually sliding and taking out the cut pipe, the threaded rod inside the storage groove rotates counterclockwise to be stored in the clamping piece. The clamping of the clamping piece can cope with the subsequent cutting of the cutting blade. The clamping piece keeps the same position after being extended and pushed. The user does not need to hold the pipe and wait for the clamping piece to unfold and adjust the position and clamp it again, which reduces the work intensity of the user when using the device. On the other hand, during the extension of the roller, the clamping piece will drive the second connecting block at one end to be stored in the active cavity, and the resetting of the roller can be pushed by the spring to reset the clamping piece. The device adapts to the extension and clamping of the threaded rod, and the cutting efficiency and cutting effect of the long pipe can be improved by the rotation of the roller.

An inner connecting tube 18 is welded to one end of the connecting frame 16, and a threaded rod 17 is provided on the outside of the inner connecting tube 18. The outside of the threaded rod 17 is matched with the internal thread of the inner connecting tube 18. The connection frame 16 can be pushed through the inner connecting tube 18 by the rotation of the threaded rod 17, and the roller 15 is driven to extend out of the storage groove 8 through the connecting frame 16;
[0024] In this embodiment, the second hydraulic telescopic rod 5 is welded with a first connecting block 9 at one end facing the clamping piece 6, and the clamping piece 6 is welded with a second connecting block 11 at one end facing the first connecting block 9. Figure 2 and Figure 3 As shown, a movable cavity 10 for movement is provided on one side of the first connecting block 9 facing the second connecting block 11, and the inside of the movable cavity 10 is connected to the external sliding slot of the second connecting block 11.

[0027] Working principle: When the device is used to cut the air-conditioning insulation pipe, before cutting, the second hydraulic telescopic rod 5 is extended and retracted after being supported by the connecting piece 4 to push the clamping piece 6, so that the two clamping pieces 6 move relative to each other to achieve clamping. The extension and retraction of the first hydraulic telescopic rod 2 can push the cutting blade 3 in a rotating state to move, so that the cutting blade 3 moves toward the fixed pipe to complete the cutting. After the cutting is completed, the cutting blade 3 is reset, and the motor 7 is started. The output shaft of the motor 7 can drive the threaded rod 17 to rotate. The rotation of the threaded rod 17 can push the inner connecting pipe 18 to move horizontally. The inner connecting pipe 18 can pass through the connecting frame 1 6 drives the roller 15 to move horizontally and extend out of the storage groove 8. After extending out of the storage groove 8 and contacting the pipe, the impact force will cause the clamping piece 6 to rebound, so that the second connecting block 11 at one end of the clamping piece 6 shrinks into the movable cavity 10. With the support of the roller 15, the cut pipe can be directly extracted, and the pipe to be cut is subsequently pushed so that the pipe is extended between the two pairs of clamping pieces 6 again. The roller 15 shrinks to the inside of the storage groove 8 after transmission. The contraction of the roller 15 and the resilience of the spring 13 can make the clamping piece 6 fit the pipe, respond to the contact of the cutting blade 3 again and complete the cutting again.
