Problems solved by technology

[0002] It is inconvenient to study and modern history. When events and related characters need to be compared and memorized, but this kind of memory is relatively boring. Many students have a hard time remembering, and they need to first correspond to time, events and characters It takes time to organize. For example, who participated in a large group and what resolutions were made. If everyone organizes a copy, it will cause a waste of resources. How to share resources and facilitate memory is a problem that needs to be solved

Embodiment 1

[0026] A modern history time, event and character corresponding query device, which consists of: a circular rotating disk 1, said circular rotating disk is provided with a central hole 2, said central hole is connected to a round rod 3, and said round rod The front end is connected with a fixed circular plate 4, the diameter of the fixed circular plate is larger than the diameter of the central hole, the fixed circular plate fixes the round rod, and the rear part of the round rod is connected with the fixed round rod 5 , the diameter of the fixed round rod is smaller than the diameter of the round rod, the fixed round rod is connected to the magnetic sleeve 6, the magnetic sleeve is attracted to the fixed iron sleeve 7, and the fixed iron sleeve is connected to the supporting device , the front of the circular rotating disk is provided with a ring groove 8, the bottom of the ring groove is connected to a magnetic ring 9, an iron ring 10 is inserted into the ring groove, and the...

Embodiment 2

[0029] In the modern history time, event and person correspondence inquiry device described in Embodiment 1, a group of split slots 12 are opened around the circumference of the circle, and a magnetic strip 13 is glued to the bottom of the split slot, and the magnetic strip 13 is attached to the bottom of the split slot. The strip attracts the iron plate 14, the iron plate is inserted into the split slot, the iron plate is vertically connected to the pressing plate 15, and the middle position of the pressing plate is vertically connected to the iron plate, A time card 16 is inserted between the pressing plates, and the split slot is located inside the circular groove.

[0030] The convenient and firm connection between the iron insert plate and the circular rotating disk can make the pressing plate firmly fix the time card, and the gap between the pressing plate and the circular rotating disk facilitates the insertion of the time card.

Embodiment 3

[0032] In the modern history time, event and person correspondence query device described in Embodiment 1, a set of mosaic grooves 17 are opened around the circumference of the circular rotating disk, and the mosaic grooves are connected to a magnetic plate 18, and the magnetic plate attracts and closes the magnetic sheet 19. The magnetic sheet is connected to the bottom of the character description board 20, and the character description board corresponds to the time card.

[0033] The magnetic plate attracts the magnetic sheet to fix the character description board, which is very convenient when the character description board needs to be replaced, and it is also very firm after the suction and bonding.
