[0015] The following will be described in detail in combination with the accompanying drawings. Figure 1 - the accompanying drawings Figure 4 The present application will be further described in detail.

[0016] Embodiment I:

[0017] A pipe diameter bushing structure for pipe processing, referring to Figures 1-4 ​, including a support disc 11, a fixed sleeve 12 and a support sleeve 13, the other side of the support disc 11 is welded with a handle 4, the handle 4 can be used for the position movement of the support disc 11, and the support disc 11 can also be temporarily supported by hand, the support sleeve 13 is welded at the middle of one side of the support disc 11, the support sleeve 13 is inserted into the pipe, and the outer side wall of the support sleeve 13 is attached to the inner side wall of the pipe, so that the support sleeve 13 plays a role of radial support to the pipe, the fixed sleeve 12 is welded at the edge of one side of the support disc 11, the fixed sleeve 12 is located outside the support disc 11, the inner side wall of the fixed sleeve 12 is provided with two arc-shaped grooves, the two arc-shaped grooves are movably provided with arc-shaped clamping blocks 21, the opposite side of the two arc-shaped clamping blocks 21 is bonded with +2, the two +2 can avoid the direct contact between the two arc-shaped clamping blocks 21 and the outer surface of the pipe, thereby avoiding the abrasion of the outer surface of the pipe caused by the resistance of the arc-shaped clamping blocks 21, the top end of the two arc-shaped clamping blocks 21 is welded with a movable block 22, the two movable blocks 22 movably penetrate the fixed sleeve 12, one side of the support disc 11 is welded with two limiting blocks 23, the two movable blocks 22 are movably sleeved outside the two limiting blocks 23, and the two inner side walls of the two movable blocks 22 are attached to the two outer side walls of the two limiting blocks 23, so that the two movable blocks 22 can only drive the two arc-shaped clamping blocks 21 to move linearly, the opposite side of the two limiting blocks 23 is threadedly penetrated by a screw 24, the thread self-locking condition of the two screws 24 depends on the helix angle, the friction coefficient and the load, the thread self-locking condition can be calculated by the following formula: self-locking condition = friction coefficient x tan (helix angle) ≥ 1, when this condition is met, the thread connection is self-locking, the above contents are all prior art, and in actual application, the corresponding self-locking angle can be set according to the friction coefficient of the material, which will not be described hereinafter, after the movable block 22 on one side of the two arc-shaped clamping blocks 21 contacts with the outer surface of the pipe, the two screws 24 are rotated, the two screws 24 exert a resistance force on the two movable blocks 22, so that the two movable blocks 22 drive the two arc-shaped clamping blocks 21 to approach each other to extrude the pipe, and at the same time, the two rubber blocks 25 are in complete resistance with the outer surface of the pipe after being pressed, so that the support disc 11 can be limited at the end of the pipe, and the support sleeve 13 can be limited inside the pipe to prevent it from moving inside the pipe.
