The working principle is as follows:
the first step is as follows: when the inside and the outside of the stainless steel pipe need to be clamped and fixed, the rotating handle 20 is rotated, the rotating handle 20 rotates to drive the second threaded rod 14 to rotate, the second threaded rod 14 rotates to drive the bevel gear 29 to rotate, the bevel gear 29 drives the bevel gear 29 on the first threaded rod 7 to rotate, the bevel gear 29 drives the first threaded rod 7 to rotate, the first threaded rod 7 rotates to drive the convex block 9 and the concave block 11 to move relatively, and the convex block 9 and the concave block 11 move relatively to drive the clamping plate 12 to move relatively, so that the stainless steel pipe is clamped;
the second step is that: further, the rotation of the second threaded rod 14 will drive the gear 28 to rotate at the same time, and further, when the gear 28 rotates, the gear 28 on the telescopic rod 8 is driven to rotate, and further, when the gear on the telescopic rod 8 rotates, the gear 28 drives the worm 31 to rotate, and further, the rotation of the worm 31 drives the pushing rod 17 to move back and forth inside the supporting rod 16, and further, since the right end of the pushing rod 17 is tapered, the pushing rod 17 is continuously enlarged, and further, the limiting plate 26 is forced to drive the clamping rod 25 to extend out from the inside of the clamping hole 23, and further, when the clamping rod 25 extends out, the clamping plate 21 is driven to disengage from the inside of the clamping groove 22, so that the contraction plate 18 is opened inside the stainless steel pipe, thereby completing the clamping of the inside of the stainless steel pipe, and further facilitating the punching of the stainless steel pipe, and further preventing the stainless steel pipe from sliding, the punching position is more accurate, and meanwhile, when the stainless steel pipe is punched due to the fact that the wall surface of the stainless steel pipe is too thin, the punching position is easy to dent, and further, the phenomenon of dent punching position during punching is avoided through the support of the contraction plate 18, so that the punching precision is improved, and the appearance of the stainless steel pipe is guaranteed not to be damaged;
the third step: when the hole is punched, the second threaded rod 14 is rotated anticlockwise, and the rotation of the second threaded rod 14 drives the gear 28 to rotate, so that the gear 28 drives the worm 31 to rotate, and then the anticlockwise rotation of the worm 31 drives the push rod 17 to move leftwards in the support rod 16, so that the limiting plate 26 is driven to be continuously reduced along with the right end of the push rod 17, and then the clamping rod 25 contracts, so that the contraction plate 18 is driven to contract, so that the inside of the stainless steel pipe is not supported any more, meanwhile, the second threaded rod 14 drives the first threaded rod 7 to rotate anticlockwise when rotating anticlockwise, so that the convex block 9 and the concave block 11 move reversely, so that the outside of the stainless steel pipe is not clamped any more, and the punched stainless steel pipe is conveniently taken down;
the fourth step: the other end of the stainless steel pipe can be supported through the supporting groove 3 formed in the supporting block 2, so that two ends of the stainless steel pipe are always kept on a horizontal line, and the phenomenon that one end of the stainless steel pipe is not supported when the stainless steel pipe is punched and the stainless steel pipe is bent is avoided, the rubber pad 4 is arranged, so that the surface of the stainless steel pipe is prevented from being abraded when the stainless steel pipe is clamped by the clamping plate 12, the brightness and the attractiveness of the stainless steel pipe are guaranteed, and the clamping can be more compact through the arranged teeth 27;
the fifth step: as the second threaded rod 14 rotates, the first threaded rod 7 and the worm 31 are simultaneously driven to rotate, so that the inner expansion fixing and the outer clamping are completed, and the pipe wall with only one thickness can be clamped, as an improvement, when facing stainless steel pipes with different pipe wall thicknesses, the gear 28 on the telescopic rod 8 can be pulled, the gear 28 is stressed to drive the telescopic rod 8 to extend, the gear 28 is not meshed with the gear 28 on the connecting rod 30, the worm 31 can be independently rotated, the rotation of the worm 31 drives the push rod 17 to move back and forth in the supporting rod 16, and as the contact area between the push rod 17 and the limiting plate 26 is continuously increased or decreased, the limiting plate 26 drives the clamping rod 25 to move up and down in the clamping hole 23, and the movement of the clamping rod 25 drives the contraction plate 18 to open and close, so as to adjust the opening and closing diameters of the contraction plate 18, after the adjustment is completed, the gear 28 on the telescopic rod 8 is pushed, and the gear 28 is forced to drive the telescopic rod 8 to contract, so that the gear 28 is engaged with the gear on the connecting rod 30 and the gear 28 on the second threaded rod 14 again.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
