By putting the pipe fitting on the inner supporting rod 202 and then positioning the position to be punched above the through hole 203, the outer wall of the pipe fitting can be prevented from being sunken when punching.

[0026] A square hole 101 is provided on the workbench 1 , and the square hole 101 corresponds to the through hole 203 , so that waste generated after punching can be discharged easily through the square hole 101 .

[0027] The clamping mechanism 3 comprises a first mounting plate 301 . The first mounting plate 301 is arranged on the workbench 1 , and two first mounting plates 301 are provided.

[0028] The first mounting plate 301 is provided with a mounting hole 307 , and the interior of the mounting hole 307 is fitted with a slide bar 302 .

[0029] An "L"-shaped block 303 is provided at one end of the slide rod 302, and a return spring 306 is sleeved on the "L"-shaped block 303. The two ends of the return spring 306 are respectively connected to the "L"-shaped block 303 and the first mounting plate 301. The pipe fitting is clamped by the "L"-shaped block 303, and the return spring 306 can drive the "L"-shaped block 303 to reset after punching.
