[0033] In the embodiment, the first clamping part 103 of the first clamping block 1 is provided with a plurality of second clamping parts 203 corresponding to the position of each first clamping part 103. By setting a plurality of first clamping parts 103 of different diameters, the corresponding size of the pipe 11 can be added, so that the local forming of the pipe 11 of different specifications can be realized, and the adaptability is good.

[0034] In the embodiment, the first upper clamping piece 101 or the second upper clamping piece 201 is movably fixed on the corresponding first lower clamping piece 102 or the second lower clamping piece 202 through the locking device 5.

[0036] In the embodiment, the first clamping block 1 and the second clamping block 2 are provided with a limiting block 7.
