The cutting knife 7 is clamped in the mounting groove 6, and the fixing block 9 and the first spring 10 limit the cutting knife 7. When beveling is required, the cutting knife 7 is pulled downward and replaced to another mounting groove 6. The first spring 10 is released to drive it to reset and fix the cutting knife 7 in the mounting groove 6. The lower end surface of the fixed frame 4 is fixedly connected to a plurality of sliding rods 11, and the sliding rods 11 are slidably connected to the base 1. The base 1 is provided with matching through holes, and a plurality of sliding rods 11 are distributed at the four corners of the fixed frame 4. The side walls of the sliding rods 11 are fixedly connected to sliding columns 12, and a clamping assembly is slidably connected to the sliding columns 12.

[0026] The clamping assembly includes a slider 13, a limiting rod 14, a clamping plate 15 and a straight groove 16. The straight groove 16 is provided on the side wall of the slider 13. The slide column 12 is slidably connected in the straight groove 16. The straight groove 16 has a certain inclination angle. A through hole is provided on the side wall of the slider 13. The limiting rod 14 is slidably connected in the through hole. The clamping plate 15 is fixedly connected to the side wall of the limiting rod 14. When the cylinder 3 is started to drive the fixed frame 4 to descend, thereby driving the cutting knife 7 to descend for cutting, the fixed frame 4 descends and drives the sliding rod 11 to descend. The sliding rod 11 drives the sliding column 12 to descend. The sliding column 12 drives the slider 13 to slide toward the cylinder 3 through the straight groove 16, thereby driving the clamping plate 15 to clamp and fix the line groove. The limiting rod 14 limits it and can adjust the distance between it and the slider 13 so that it can clamp and fix line grooves of different widths.

[0027] In this embodiment, as a preferred solution, the clamping assembly also includes a second spring 17, one end of the second spring 17 is fixedly connected to the side wall of the clamping plate 15, the other end of the second spring 17 is fixedly connected to the slider 13, the second spring 17 is sleeved on the outer surface spring of the limiting rod 14, the second spring 17 applies a certain pressure to the clamping plate 15, when the clamping plate 15 contacts the line groove, and the slider 13 is still sliding, the clamping plate 15 moves away from the line groove under the action of the limiting rod 14, and the second spring 17 applies a certain pressure to the clamping plate 15, so that it can clamp and fix the line groove, and enable it to adapt to line grooves of different widths.

The end of the limit rod 14 away from the clamping plate 15 is fixedly connected to the limit block 19. The limit block 19 limits the limit rod 14 to prevent it from detaching from the slider 13.

[0030] In this embodiment, as a preferred solution, a groove is opened on the upper end surface of the base 1, and a conveyor belt is arranged in the groove. The conveyor belt is located in the center of the base 1, and the upper end surface of the conveyor belt is parallel to the upper end surface of the base 1. The conveyor belt will not be damaged when the line groove is cut. The line groove is placed on the conveyor belt for automatic loading, without the need for frequent manual operation, which is more labor-saving.

The scale is located on the side of the conveyor belt and is embedded in the base 1, so as to facilitate measuring the length of the line trough as needed.

[0032] When the utility model is used, the line groove is placed in the conveyor belt. When the line groove moves to the distance required for cutting, the cylinder 3 is started. The cylinder 3 drives the fixing frame 4 to descend, thereby driving the mounting block 5 to descend, and driving the cutting knife 7 arranged on the mounting block 5 to cut the line groove. When the fixing frame 4 descends, the fixing frame 4 descends and drives the slide bar 11 to descend. The slide bar 11 drives the slide column 12 to descend. The slide column 12 drives the slide block 13 to slide toward the cylinder 3 through the straight groove 16, thereby driving the clamping plate 15 to clamp and fix the line groove, so that the two ends of the line groove are clamped and fixed during cutting, so that the edge of the cut line groove is neat and has no burrs, which is very beautiful. By adjusting the mounting groove 6 at different positions of the cutting knife 7, the cutting angle can be adjusted so that the cutting angle of the tangent or bevel cutting is consistent, which is convenient for subsequent splicing and installation.
