[0031] Specifically, the limit assembly includes a limit rod 8, a limit box 9, a limit slot 1 10, a limit slot 2 11, and a limit plate 12. The limit rods 8 are fixedly arranged at the four corners of the lower end surface of the connecting plate 6, and the limit plate 12 is fixedly arranged on the lower end surface of the limit rod 8. The advantage is that the limit rod 8 and the limit plate 12 will also drop synchronously when the tube is expanded.

[0032] Specifically, the four corners of the upper end surface of the base 1 are fixedly provided with a limit box 9, the upper end surface of the limit box 9 is provided with a limit slot 10, the interior of the limit box 9 is provided with a limit slot 2 11, the limit slot 10 and the limit slot 2 11 are communicated, the limit rod 8 is arranged inside the limit slot 10, and the limit plate 12 is arranged inside the limit slot 2 11. The advantage is that the opening of the limit slot 10 can play a role in limiting the limit rod 8, and the opening of the limit slot 2 11 can play a role in limiting the limit plate 12, so that the limit rod 8 and the limit plate 12 can move downward steadily, and then the expansion head 7 can move downward steadily.

[0033] Embodiment 2:

[0034] like Figure 1 , Figure 2 , Figure 4 As shown, as an improvement to the previous embodiment. Specifically, the clamping assembly includes a mounting groove 16, a protrusion 17, a mounting groove 2 18, and a spring 19. The interior of the placement groove 14 is provided with a tube 15. The interior of the placement groove 14 is provided with mounting grooves 16 all around, and the interior of the mounting groove 16 is provided with a protrusion 17. The advantage is that the opening of the mounting groove 16 facilitates the setting of the protrusion 17, and the setting of the protrusion 17 can play a role in centering the tube 15.

[0035] Specifically, two upper and lower mounting grooves 18 are formed on the outer side of the protrusion 17, and a spring 19 is fixedly arranged on the inner side of the mounting groove 18, and the other end of the spring 19 is mounted on the side wall inside the mounting groove 16. The advantage is that when a person places the pipe 15 in the placement groove 14, the protrusions 17 around are squeezed and move toward the inside of the mounting groove 16, and the spring 19 is compressed, and the rebound force of the spring 19 reacts on the protrusion 17, so that the protrusions 17 around can center and clamp the pipe 15.

At this time, the protrusions 17 around it are squeezed and move toward the inside of the installation groove 16. The spring 19 is compressed, and the rebound force of the spring 19 reacts on the protrusion 17. The protrusions 17 around it can thus center and clamp the tube 15. Then, the expansion mechanism 5 is started through the control panel 20. The expansion mechanism 5 can drive the connecting plate 6, the expansion head 7, the limit rod 8, and the limit plate 12 to move downward. At this time, the limit rod 8 is limited by the limit groove 10, and the limit plate 12 is limited by the limit groove 2 11 and can move downward smoothly, so that the expansion head 7 can also move downward smoothly, thereby ensuring that the position of the expansion head 7 can always match the tube head of the tube 15, so that the expansion operation can be carried out on it, ensuring the quality of processing.
