It is worth noting that the specific structure of the flanging machine body 1 and the flanging assembly 12 and their working methods are all existing technologies currently disclosed on the market, and do not belong to the main technical problems to be solved in this technical solution, so they are not described in detail in this utility model.

[0023] In addition, the auxiliary clamping assembly 3 includes a fixing ring 31, a through hole is opened through the middle part of the fixing ring 31, extension plates 32 are symmetrically arranged on both sides of the fixing ring 31, and cavities are symmetrically opened in the fixing ring 31 between two adjacent extension plates 32 at equal distances, a limiting plate 333 is movably arranged in the cavity, three connecting rods 332 are equidistantly arranged on one side of the limiting plate 333, one side of the connecting rod 332 extends to the through hole and is connected to the clamping plate 331, and a limiting assembly 34 is movably arranged on the other side of the limiting plate 333.

[0024] At the same time, the limiting assembly 34 includes a fixed rod 341, one side of the fixed rod 341 is a left and right auxiliary limiting ring 342, the other side of the fixed rod 341 passes through the fixed ring 31 and is connected to a handle assembly 344, and the outer wall of the fixed ring 31 is close to the side of the handle assembly 344 with a clamping block assembly 343.

[0025] At the same time, the handle assembly 344 and the clamping block assembly 343 both include a limiting fixing ring, and extending protruding rods are symmetrically provided on both sides of the limiting fixing ring, and the diameter of the limiting fixing ring is larger than the diameter of the fixing rod 341.

[0026] When the limiting plate 333 is located on the side of the through hole in the cavity, the clamping block assembly 343 is located in the fixed ring 31, and the fixed ring 31 is provided with a movable cavity at the clamping block assembly 343. At the same time, a feed through hole is provided on the outer wall of the fixed ring 31 at the movable cavity. The cross-sectional area of the feed through hole is consistent with the cross-sectional area of the clamping block assembly 343.

[0027] Furthermore, a clamping cavity is defined in the limiting plate 333 at the auxiliary limiting ring 342 , a through hole is defined in the limiting plate 333 at the fixing rod 341 , and a sliding through hole is defined in the fixing ring 31 at the fixing rod 341 .
