[0025] In order to make the purpose, technical scheme and advantage of the utility model more clearly, the following is further detailed to the utility model by combining with drawing and embodiment.It should be understood that the specific embodiment described here is only used to explain the utility model, and is not used to limit the utility model.
[0026] Embodiment;
[0027] As Figures 1-4 The plastic pipe cutting line marker shown in the drawing, including shell 1, the upper end of shell 1 is through and movably connected with pressing rod 2, the lower end of pressing rod 2 is fixedly connected with connecting block 3, the upper end of connecting block 3 is fixedly connected with a pair of springs 4, the upper end of a pair of springs 4 is fixed with the inner top end of shell 1, the lower surface of connecting block 3 is fixedly connected with evenly distributed connecting rod 5, the lower end of connecting rod 5 is sleeved with adjusting rod 6, the lower end of adjusting rod 6 is embedded with talc pencil 7;
[0028] One side of shell 1 is screw connected with threaded rod 8, one end of threaded rod 8 is rotatably connected with clamping block 9, one side of clamping block 9 is in contact with adjusting rod 6.
[0029] In use, first select the correction point on the pipe, the line marker is placed above the pipe, and the pressure rod 2 is pressed down, the pressure rod 2 cooperates with the connecting rod 5 and the adjusting rod 6 to drive the chalk 7 to move down, when the adjusting rod 6 contacts the pipe surface, the connecting rod 5 continues to move down and is retracted into the adjusting rod 6, until the chalk 7 at the lower end of the adjusting rod 6 fully matches the outer arc of the pipe, then the threaded rod 8 is rotated, so that the clamping block 9 tightly clamps the adjusting rod 6, and the chalk 7 is kept stable under the matching outer arc of the pipe, then if the pipe needs to be marked and cut, the line marker is pressed on the pipe surface to leave a long effective cutting point line, which is efficient and can be operated by a single person.
[0030] It should be noted that a single chalk 7 can only leave one mark point on the pipe surface, and multiple chalks 7 of the line marker can leave multiple mark points on one side of the pipe in use, and then the pipe can be rotated as needed, and the other side of the pipe can be marked again using the line marker. Then, the pipe is cut along the multiple mark points, and the cutting work is completed. In actual use, the number of chalks 7 can be adjusted according to the precision required, to increase the density of mark points and improve the marking precision of the point line formed by the mark points.
[0031] As shown in Figure 4 , the lower end of the connecting rod 5 is fixedly connected with a limiting sliding block 501, and the inner wall of the adjusting rod 6 is provided with a sliding groove 602, one end of the limiting sliding block 501 extends into the sliding groove 602, and the lower end of the connecting rod 5 is further fixedly connected with a rubber plug 502, and the outer circumferential surface of the rubber plug 502 is in close contact with the inner wall of the adjusting rod 6.
[0032] In use, the sliding groove 602 and the limiting sliding block 501 are used to prevent the adjusting rod 6 from accidentally falling off and being lost, and the rubber plug 502 is used to increase the friction between the connecting rod 5 and the adjusting rod 6, so that the adjusting rod 6 can be kept stable after adjustment, and the threaded rod 8 can be easily tightened.
[0033] As shown in Figure 4 , the inner wall of the shell 1 is fixedly connected with a stop rod 10, the upper end of the connecting rod 5 is fixedly connected with a limiting block 503, and the upper end of the limiting block 503 is in contact with the stop rod 10.
[0034] When in use, when the threaded rod 8 is loosened, the clamping block 9 is not clamped on the adjusting rod 6, the adjusting rod 6 will be reset under the pulling force of the spring 4, and since the leather plug 502 makes the connecting rod 5 and the adjusting rod 6 have a certain stability, after reset, the connecting rod 5 and the adjusting rod 6 will also remain in the adjusting state, which is inconvenient for secondary adjustment, therefore, through the limiting of the limiting block 503 by the stop rod 10, the adjusting rod 6 cannot continue to move upwardly along with the connecting rod 5 after reaching the initial position, until all the adjusting rods 6 are flush again, which is convenient for personnel to adjust again.
[0035] As shown in Figure 1 and 4 , one end of the threaded rod 8 is fixedly connected with a pair of force columns 801, and the pair of force columns 801 are symmetrically distributed on the outer circumferential surface of the threaded rod 8.

[0038] In use, when the slate pencil 7 is worn out, the slate pencil 7 can be disassembled and replaced.
[0039] In summary, the specific working process of the scheme is as follows: first, select the correction point on the pipe, place the line marker above the pipe, and press down the pressure rod 2, and the pressure rod 2 drives the adjusting rod 6 to move downwardly through the cooperation of the link block 3 and the connecting rod 5, when the adjusting rod 6 contacts the pipe surface, the connecting rod 5 continues to move downwardly and is retracted into the adjusting rod 6, until the slate pencil 7 at the lower end of all the adjusting rods 6 fully matches the outer arc of the pipe, then rotate the threaded rod 8, so that the clamping block 9 fully clamps the adjusting rod 6, and then the slate pencil 7 remains stable under the matching of the outer arc of the current pipe, then if the pipe needs to be marked and cut, the line marker only needs to be pressed on the pipe surface to leave a long effective cutting line, which is high in efficiency and can be completed by a single person.
[0040] The above merely describes a preferred specific embodiment of the present application; however, the protection scope of the present application is not limited thereto. Any skilled person in the art, according to the technical scheme and improvement concept of the present application, can make equivalent replacement or change within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
