Embodiment 1
[0031] Such as Figure 1 to Figure 6 As shown, a mind-mapping tool for economic management includes a housing 1. The lower side of the housing 1 is provided with a first suction cup 2 located in the center of the housing 1 for fixing the housing 1. The first suction cup 2 can hold the housing 1 for fixing, adopting the structure of the suction cup, unlike the node block in the prior art, which must be placed on the magnetic plate before it can be used, it can be used on any smooth or flat screen, expanding the scope of use of the device; the shell 1 There are a plurality of recyclable paper rolls 3 protruding outward from the circumference. The paper rolls 3 are fixed in the housing 1 through the paper roll tightening device 4. When in use, the paper rolls 3 are pulled out from the housing 1 for use. Finally, the roll paper tightening device 4 collects the roll paper 3 into the housing 1 for collection and storage to avoid loss; the roll paper tightening device 4 is fixed on t...
Embodiment 2
[0036] Embodiment 2: On the basis of Embodiment 1, the outer side of the column 5 is sleeved with a rotating shaft 34 through the first bearing 33, the rotating shaft 34 is fixedly connected to the disc 16, and the disc 16 is connected to the column 5 through the rotating shaft 34 in rotation , so that the disk 16 can rotate on the column 5, and the direction in which the roll cloth 3 protrudes from the housing 1 also changes, which can be quickly realized when an angle change is required when drawing some maps.
[0037] In this embodiment, the slot 32 is a fan-shaped structure that gradually increases from the center of the housing 1 to the outside. The slot 32 is provided with a shaft protruding from the outside of the housing 1 and one end is fixed to the rotating shaft 34. The operating rod 35 is fixedly connected to the rotating shaft 34 so that the operating rod 35 can control the rotation of the rotating shaft 34, and indirectly control the change of the output angle of ...
Embodiment 3
[0041] Embodiment 3: On the basis of Embodiment 1 or 2, the housing 1 is elongated, and the lower side of the housing 1 is provided with a first sucker 2 located in the center of the housing 1 for fixing the housing 1. Paper rolls 3 protrude from both ends of the body 1 , a plurality of paper rolls 3 protrude from one side of the housing 1 , and fixed blocks 6 are provided at the ends of the paper rolls 3 .
[0042] The casing 1 is in the shape of a long strip, and there is a paper roll 3 on one side. The casing 1 can be used as an intermediate node or a final node. When arranging a pyramid-shaped mind map, the casing 1 will be very convenient.
