[0029] In this embodiment, the user uses the three-jaw chuck 16 to clamp the metal pipe, and then uses the adjustment structure to adjust the height of the adjustment platform 19, and uses the downward pressing structure to press down at the same time to improve the stability of the metal pipe during the knurling process. After the preparation is completed, the first rotating motor 15 is started to drive the three-jaw chuck 16 to rotate, the metal pipe rotates synchronously, and the moving structure is started synchronously, so that the outer surface of the metal pipe is fully knurled.

[0030] In one embodiment, Figure 2 and Figure 4 As shown, the adjustment structure includes a left mounting plate 17 and a right mounting plate 18, a second rotary motor 22 is mounted on the upper end of the left mounting plate 17, the output end shaft of the second rotary motor 22 extends to the lower end of the left mounting plate 17 and is fixedly connected to a first screw rod 23, the first screw rod 23 is threadedly connected to a left bottom plate 20, the left bottom plate 20 is fixedly connected to the left side of the adjustment platform 19, a right bottom plate 21 corresponding to the left bottom plate 20 is fixedly connected to the right side of the adjustment platform 19, the right bottom plate 21 is slidably connected to a first limiting rod 24, the bottom end of the first limiting rod 24 is fixedly connected to the upper end of the base 11, and the top end of the first limiting rod 24 is fixedly connected to the lower end of the right mounting plate 18. The second rotary motor 22 drives the first screw rod 23 to rotate, and due to the limiting effect of the first limiting rod 24, the first screw rod 23 drives the adjustment platform 19 to rise and fall, and when the adjustment platform 19 rises and falls, the moving structure is driven to rise and fall.

[0031] In one embodiment, Figure 1 and Figure 5As shown, the mobile structure includes a third rotating motor 25, which is installed on the left side of the front end of the adjustment platform 19. The output end shaft of the third rotating motor 25 extends to the inside of the adjustment platform 19 and is fixedly connected to the second screw rod 26. The right side of the adjustment platform 19 is fixedly connected to the second limiting rod 27. The second screw rod 26 is threadedly connected to the moving platform 28.

Due to the limiting effect of the first limiting rod 24, the first screw 23 drives the adjustment platform 19 to rise and fall, and the moving platform 28 rises accordingly, and the two knurled guide rollers 29 also rise accordingly. At the same time, the user starts the first push rod 35 and the second push rod 37. The first electric push rod 35 pushes the top plate 36 to rise to a certain height, and the second electric push rod 37 drives the top plate 36 to rise to a certain height. 37 pushes the pressure roller 39 downward until the two knurled guide rollers 29 and the pressure roller 39 apply a certain pressure to the metal pipe. Next, the user starts the first rotating motor 15 to drive the three-jaw chuck 16 to rotate, and the metal pipe rotates synchronously. At the same time, the third rotating motor 25 is started, and the third rotating motor 25 drives the second screw 26 to rotate.
