One end of the screw has a head, which is housed in a second groove. The outer diameter of the head is larger than the outer diameter of the first threaded portion. A fourth flange is provided on one side of the head. The other end of the screw has a fitting portion. A first washer is housed in the second groove and abuts against the second flange. The first washer has a through hole through which the screw passes. A first spring is fitted onto the screw and housed in the second groove. The first spring abuts against the fourth flange and the first washer. The spring's elasticity causes the head to abut against the third flange. A control group is configured with the sliding group and the screw group. The rotation of the screw group can drive the control group and the sliding group to move linearly, thus having a fine-tuning displacement function. Actuating the control group disengages it from the screw group, so that the rotation of the screw group can no longer drive the control group and the sliding group to move. Actuating the control group drives the sliding group to move linearly at the first receiving groove, thus having a rapid displacement function. The screw group prevents the control group from disengaging from the sliding group.A rotating component, pivotally mounted outside the main body, is assembled with the screw assembly. Rotation of the rotating component drives the screw assembly to rotate. The elastic force of the first spring body enables the screw assembly to return to its original position. A workpiece is provided, and the cutting wheel rests against the workpiece using the elastic force of the first spring body. When the cutting wheel cuts the workpiece, the outer diameter of the workpiece decreases due to the cutting, and the cutting wheel, under the elastic force of the first spring body, then automatically feeds.

The first central axis and the second central axis are located on different planes. The second central axis and the third central axis are parallel to each other. The two roller assemblies are respectively pivotally mounted at the second central axis and the third central axis. The roller assemblies are wheel-shaped and will roll naturally.

5. The pipe cutter structure as described in claim 3, wherein, The sliding seat abuts against the first abutment, and the sliding seat partially protrudes from the space. One end of the sliding seat has a fourth receiving groove facing the third receiving groove. The fourth receiving groove has a fifth pivot portion, which is shaped like a through-hole and communicates with the fourth receiving groove. The sliding seat also has a sixth pivot portion, which is aligned with the first and second pivot portions and penetrates the sliding seat. The sliding seat has a fifth receiving groove at its other end, which communicates with the sixth pivot and is aligned with the space. The cutting wheel system is pivotally mounted at the fourth receiving groove and is aligned with the roller assembly. The cutting wheel shifts towards and away from the roller assembly. The cutting wheel system is circular in the shape of a blade. The cutting wheel shaft system passes through the fifth pivot and is pivotally mounted with the cutting wheel. The cutting wheel shaft has a T-shaped long rod cross-section.

6. The pipe cutter structure as described in claim 5, wherein, The first threaded part is pivotally mounted at the first pivot, the second pivot and the sixth pivot. The first threaded part and the sixth pivot have a loose fit structure. The fitting part is a non-circular column or a hexagonal column. The first elastic system is a spring body.

7. The pipe cutter structure as described in claim 6, wherein, The control assembly is housed in the fifth accommodating groove and is movable within the fifth accommodating groove. Part of the control assembly protrudes from the fifth accommodating groove and the space for pressing. The control assembly protruding from the space is positioned on the two sides of the main body and the sliding assembly, respectively, along with the cutting wheel.

8. The pipe cutter structure as described in claim 7, wherein, The control assembly includes a pressing member, a control member, and a second spring; the sliding assembly is linearly displaced within the main body, and the control assembly is linearly displaced on the sliding assembly, with the displacement direction of the control assembly perpendicular to the displacement direction of the sliding assembly; the pressing member is housed in the fifth receiving groove and can be moved within the fifth receiving groove, with a portion of the pressing member protruding outside the fifth receiving groove and the space; the pressing member has a sixth receiving groove for the screw to pass through; the pressing member also has a seventh receiving groove... The groove is open, giving the pressing member a slightly U-shaped form. The pressing member has a first slide rail located between the seventh and sixth receiving grooves, and the first slide rail is a series of opposing grooves. The control member is assembled with the pressing member and is housed within the seventh receiving groove. One end of the control member has a second threaded portion that engages with the first threaded portion. The control member has a second slide rail on both its upper and lower sides, which accommodates the first slide rail. The slide rail is convex in shape, and the other end of the control component has a spring groove. This spring groove is not connected to the second threaded part. The control component is non-circular. The second spring is housed in the spring groove, with one end abutting against the spring groove and the other end abutting against the bottom of the fifth groove. The second threaded part is engaged with the first threaded part by the elastic force of the second spring. The second spring is a spring body. The screw assembly restricts the control component, and the control component further restricts the pressing component. The control assembly is thus assembled into the sliding assembly. The control group is not disengaged, meaning it is constrained by the screw assembly. Pressing the control group causes the pressing element and the control element to displace within the fifth groove, compressing the second elastic body and disengaging the second threaded portion from the first threaded portion. The operator can then push the control group, thereby displacing the sliding assembly to adjust the distance between the cutting wheel and the roller assembly. Releasing the press on the control group causes the elastic force of the second elastic body to engage the second threaded portion with the first threaded portion, thereby positioning the sliding assembly and the control group.

9. The pipe cutter structure as described in claim 3, wherein, At least one ring is provided, which is assembled on the third pivot. The ring and the third pivot are tightly fitted. There are two rings, which are colored rings. The rotating member is pivotally mounted on the fourth pivot, and the two rings are hidden inside the rotating member.

10. The pipe cutter structure as described in claim 9, wherein, A workpiece is placed at the two roller sets, aligned with the cutting rollers in preparation. The cutting rollers can then be moved to approach the workpiece. By pressing the control group, the operator can continuously press and push the control group to move the sliding group, thereby adjusting the distance between the cutting rollers and the workpiece. When the cutting rollers cut into or approach the workpiece, the control group is released and positioned. The rotating component is then rotated to fine-tune the displacement effect. After the cutting rollers abut against the workpiece, the rotating component is rotated further. The sliding group cannot be moved. The sliding group forces the screw assembly and the rotating component to rotate in the opposite direction, causing the head to move and not abut against the third abutment. The first elastic body is compressed. After the rotating component is displaced, the two rings are exposed.

11. The pipe cutter structure as described in claim 8, wherein, The outer side of the main body is provided with a receiving groove and a label.
