The line width of the light red water-colored paint line 3011 is about 1 mm, and the light red water-colored paint line 3011 does not affect the reflection of the mirror light. The light receiver board B302 is made of transparent acrylic material, and is penetrated by an oblong hole 3021 with a width of about 1.3 mm.

The light receiver board C303 is also made of transparent acrylic material. As a base board, the angle between the light receiver board C303 and the light receiver board B302 is 90°.

[0049] Below, refer to Figure 1-Figure 21 Combined with the description of the above structural features, the specific operation method of the portable positioning tool for marking and drawing lines on the factory floor of the utility model is briefly described:

[0050] The purpose of the two workers is to carry out 90° and 45° angle marking and line laying work.

[0051] In the first step, two workers marked the reference line 4 and used it as the reference line for determining the 90° and 45° lines later;

[0052] In the second step, the worker places two infrared laser pens 2 on the circular holes A1011 and B1012 on the fixed column 101 in the light emitting frame 1, and adjusts the positions of the two infrared laser pens 2 so that the central axis coincides with the 0° and 90° scale lines of the angle disk 102 in the light emitting frame 1 in the top view. After that, the worker places the light emitting frame 1 at the identification reference line 4, and adjusts the conical screw head 1042 and the screw rod 1041 by rotation, so that the bubble 1033 in the level 103 placed in the light emitting frame 1 is centered on the circular scale line 1032 to achieve the leveling of the light emitting frame 1. Finally, the position is fine-tuned so that the extension line of the 0° scale line of the angle disk 102 in the light emitting frame 1 visually coincides with the identification reference line 4 in the top view, and a marking pen is used to make a 90° angle reference point 5, a 45° angle reference point 6, and a 0° angle reference point 7 on the ground.

[0053] The third step is to turn on the infrared laser pen 2 so that the infrared light beam passes through the oblong hole 3021 in the light receiver board B302 in the light receiver 3 and illuminates the light red watercolor paint line 3011 in the light receiver board A301. The light passes through the oblong hole 3021 again and reflects on the ground to form a point, which coincides with the ray of the infrared light beam in the bird's-eye view. This is used as the standard method of using the light receiver 302 to determine the point position.

[0054] The fourth step is to turn on the infrared laser pen 2 placed in the circular hole B1012. The light receiver 302 can reflect a point on the ground as the 0° angle reflection point 10. This point coincides with the identification reference line 4, indicating that the position adjustment of the light emitting frame 1 has been completed and the angle point measurement can be carried out.

[0055] The fifth step is to turn on the infrared laser pen 2 placed in the circular hole A1011, and the light is projected onto the light receiver 302. By adjusting the light receiver 302, the light is smoothly reflected on the ground to form a 90° angle reflection point 8.

[0056] Step 6: Form a 90° positioning line through the 90° angle reference point 5 and the 90° angle reflection point 8.

[0057] Step 7: If you need to place a 45° line, just turn on the infrared laser pen 2 placed on the circular hole C 1013. By adjusting the position of the light receiver 302, a 45° reflection point 9 is formed on the ground to mark it.

[0058] Step 8: Connect the 45° angle reference point 6 and the 45° angle reflection point 9 to form a 45° positioning line.

[0059] In the ninth step, the ground marking line 11 can be drawn freely based on the identification reference line 4, the 90° positioning line and the 45° positioning line. The ground marking line is drawn according to the requirements of the drawing, and the angle positioning point method is determined according to the above method.

[0060] The above is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be understood by anyone familiar with the technology within the technical scope disclosed by the present invention should be included in the scope of the present invention.
