At the same time, the front end of the brake lever 24 is pushed up, causing the rear end of the brake lever 24 to rotate downward and contact and press the driven wheel 12, so that the driven wheel 12 decelerates and stops.

[0064] The convex parts of the cam I 50 and the cam II 51 are staggered, and the staggered position is exactly one step turning distance stroke. The convex parts of the cam II 51 and the cam III 52 are staggered, so that the cutting tool 43 cuts first, and then the driven wheel 12 decelerates and stops, enabling the pipe material feeding mechanism to feed.

[0065] The second pipe processing device further includes a finished product conduit 56. The finished product conduit 56 is clamped and installed at the rear part of the left end of the bottom plate 1 by a conduit clamp 57. It is provided with a V-shaped groove 58. The center of the V-shaped groove 58 is a finished product channel. The front end of the pipe material extends into the center of the V-shaped groove 58. The cutting tool 43 enters the center of the V-shaped groove 58 under the push of the cam I 50 to complete the cutting. The step turning tool 35 enters the V-shaped groove 58 under the push of the cam II 51 to perform step turning on the pipe material.

[0066] In the description of this embodiment, the orientation or positional relationship terms such as "upper", "lower", "right", "left", "rear", "front", etc. are based on the Figure 1 orientation or positional relationship shown. It is only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, so it cannot be understood as a limitation of the present invention.
