It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model. Example

[0032] like Figure 1-8As shown, this utility model discloses a magnetic ruler capable of horizontal calibration, comprising a ruler body 1 and an insert plate 13. The ruler body 1 has grooves 2 on one side near the other two sides. Each groove 2 has a bearing 3 on both sides inside. Rotating rods 4 are connected to opposite sides of the four bearings 3. Two magnets 5 are connected to opposite sides of the four bearings 3 via the four rotating rods 4. A circular groove 6 is provided on one side of the ruler body 1 near the opposite sides of the two grooves 2. A groove is provided between the top and bottom surfaces of each circular groove 6. A first bubble level 7 is provided. A placement groove 8 is provided at the center of one side of the ruler body 1. A second bubble level 9 is provided between opposite sides inside the placement groove 8. A first slot 10 is provided at the center of the bottom of the ruler body 1. A second slot 11 is provided near both sides of the bottom of the ruler body 1. A fixing component 12 is provided on one side of the ruler body 1. A mounting plate 14 is provided on the top of the insert plate body 13. A toggle area 15 is provided on the bottom of the insert plate body 13. Two moving ports 16 are provided on one side of the mounting plate 14. Example

[0033] like Figure 1-8 As shown, the fixing component 12 includes a mounting groove 121, which is located on one side of the ruler body 1. Two storage slots 122 are provided on one side of the mounting groove 121. A spring 123 is provided on one side of the interior of each storage slot 122. A circular plate 124 is provided on one side of each spring 123. A second bearing 125 is provided on one side of each circular plate 124. A rotating rod 126 is connected to one side of each second bearing 125.

[0034] In this embodiment, the mounting groove 121 facilitates the fitting and fixing of the mounting plate 14, the storage groove 122 can store the spring 123, the spring 123 can support the circular plate 124, the circular plate 124 can facilitate the support of the second bearing 125, the second bearing 125 can facilitate the fixing of the rotating rod 126, allowing the rotating rod 126 to rotate, and the rotating rod 126 can support the rotating plate 127. Example

[0035] like Figure 1-8 As shown, each rotating rod 126 has a rotating plate 127 on one side, and each rotating plate 127 has a handle 128 on one side. The ruler body 1 has a rotating opening 17 on one side near one of the circular grooves 6. The rotating opening 17 has a rotating shaft 18 inside, and the rotating shaft 18 has a protective sleeve 19 outside.

[0036] In this embodiment, the rotating plate 127 can easily support the connecting handle 128, and the handle 128 can make it easy for personnel to pull the rotating plate 127 to rotate, so that the rotating plate 127 can be pulled out and the spring 123 can be used to elastically squeeze the mounting plate 14. The rotating port 17 can easily set the rotating shaft 18, and the protective cover 19 can be rotated through the rotating shaft 18, so that the top of the ruler body 1 can be protected by the protective cover 19 when not in use.

[0037] Working principle:

[0038] When the ruler body 1 needs to be used, the protective sleeve 19 can be rotated to one side by rotating the shaft 18. By pulling the handle 128, the rotating plate 127 can be rotated and moved. The second bearing 125 and the rotating rod 126 allow the rotating plate 127 to rotate freely. When the rotating plate 127 is rotated to a position where it can pass through the moving opening 16, the elasticity of the spring 123 pulls the circular plate 124 and the second bearing 125 back to their original positions, allowing the rotating plate 127 and the handle 128 to pass through the moving opening 16. Without the elasticity of the spring 123 pulling the rotating plate 127 and locking the mounting plate 14, the mounting plate 14 can be installed in the mounting slot 121. The mounting plate 14 can be pulled out laterally, and the mounting plate 14 can move laterally along with the insert plate body 13. The actuating area 15 under the insert plate body 13 can help the personnel to push out the insert plate body 13 inserted into the first slot 10 and the second slot 11. In this way, the first bearing 3 inside the groove 2 of the ruler body 1 can be used to allow the rotating rod 4 to rotate freely. The rotating rod 4 is connected to the magnet body 5, which can be easily attached to the three-dimensional building objects, eliminating the need for personnel to manually support and fix the measurement. The fixation method of adsorption can prevent slippage caused by personnel holding, and can improve the accuracy of measurement as much as possible. This is suitable for use in a variety of scenarios and improves the flexibility of the ruler body 1.

[0039] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
