All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0024] Example: like Figure 1-5 As shown, this embodiment provides a multi-purpose collar-type rotatable ruler, including a main ruler 1, a dividing ruler, a secondary ruler 2, a rotating assembly, and a sliding assembly; The main scale component 1 is provided with a placement cavity 3 for placing the dividing scale component. The dividing scale component is rotatably engaged with the main scale component 1 through a rotating assembly. The sliding assembly includes a slider 4 and a support 5. The support 5 is hinged to the slider 4. The measuring tool is provided with a slot 18 for placing the support 5 and a groove 19 that slides with the slider 4. The auxiliary ruler 2 is detachably connected to the main ruler 1; The main scale piece 1, the dividing scale piece, and the auxiliary scale piece 2 are equipped with a scale section 6.

[0025] This embodiment of the multi-purpose rotatable ruler with a collar has a placement cavity 3 for storing the measuring parts. The measuring parts can be inserted into the placement cavity 3 through the rotating component, thereby folding and reducing the overall area for easy carrying by the user. The size of the entire ruler can be changed by rotating the measuring parts to meet different measurement requirements. At the same time, the measuring parts are equipped with a slider 4 and a support 5 to measure the concrete spread. The auxiliary ruler 2 can measure the concrete slump, thus expanding the applicability of the measurement.

[0026] The specific structure of the rotating component in this embodiment is as follows: It includes a connecting seat 7, a connecting ring 8, and a nut 9. The connecting ring 8 is located on the connecting seat 7, and one end of the connecting ring 8 is threadedly connected to the nut 9. The main scale component 1 and the dividing scale component are provided with connecting holes 10 that mate with the connecting ring 8. The size of the connecting hole 10 is smaller than the size of the connecting seat 7.

[0027] Specifically, the main scale piece 1 has openings on both sides and one end that communicate with the placement cavity 3; The measuring component can enter and exit through the opening and rotate relative to the main measuring component 1.

[0028] In this embodiment, to ensure the relative positional relationship between the main scale component 1 and the dividing scale component during rotation, a limiting structure is provided, as follows: A first limiting component is provided on the main scale member 1. The first limiting component has a retractable or extendable limiting part. When one end of the dividing scale member is outside the placement cavity 3 and the other end of the dividing scale member abuts against the first limiting part in the extended state, the included angle between the dividing scale member and the main scale member 1 is 90°.

[0029] The first limiting component includes a limiting seat 11 and a limiting bolt 12. The limiting seat 11 is located on the main scale 1. The limiting bolt 12 is threadedly engaged with the limiting seat 11 and the main scale 1. One end of the limiting bolt 12 is a limiting part. When one end of the limiting bolt 12 is inside the placement cavity 3, the limiting part is in an extended state.

[0030] Meanwhile, a second limiting component is provided on the main scale component 1. The second limiting component has the same structure as the first limiting component.

The support 5 on the slider 4 is then aligned with the two endpoints of the maximum diameter of the concrete spread surface, thereby achieving the measurement of the maximum diameter of the concrete spread surface. Moreover, the support 5 ensures that the first measuring component 13 and the second measuring component 14 accurately read the maximum diameter of the concrete spread surface, facilitating accurate confirmation of the midpoint position of the maximum diameter of the concrete spread surface.

[0032] When the angle between the measuring tool and the main measuring tool 1 is 180°, the entire ruler can be lengthened to measure a longer range of dimensions.

[0033] In this embodiment, a magnetic suction part 16 is provided on the main ruler 1 along its length extension direction, and a magnetic suction seat 17 is provided on the secondary ruler 2 that is magnetically attracted to the magnetic suction part 16.

[0034] Based on the above structure, the auxiliary ruler 2 is attached to the magnetic suction part 16 by the magnetic suction seat 17 to form a setting structure perpendicular to the main ruler 1. By adjusting the relative position of the auxiliary ruler 2 and the main ruler 1, the highest point of the collapsed concrete can be measured.

[0035] In this embodiment, the support member 5 is T-shaped, and the slot is also T-shaped.

[0036] Specifically, the measuring range of the scale section 6 on the main scale component 1, the dividing scale component, and the auxiliary scale component 2 is 50CM, and the length of the main scale component 1, the dividing scale component, and the auxiliary scale component 2 is greater than 50CM.

[0037] Specifically, the length of the support member 5 is 15-20CM, and the length of the sliding groove is 15-45CM.

[0038] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way.
