[0026] The present invention will now be further described with reference to the accompanying drawings and exemplary embodiments. The illustrative embodiments and descriptions herein are used to explain the invention, but are not intended to limit the invention. Furthermore, detailed descriptions of known technologies that are unnecessary to illustrate the features of the present invention are omitted.

[0027] Example: Reference Figures 1-10 The diagram shows a rapid demonstration device for financial and economic education, comprising a frame 1 and three display devices. Each display device is located inside the frame 1 and includes a bar display mechanism 2, a digital display mechanism 3, an adjustment mechanism 4, a knob reset mechanism 5, and a return mechanism 6. The frame 1 includes a digital display window 101 and a bar display window 102. The bar display mechanism 2 includes a damping seat 201 and a winding plate 203. The digital display mechanism 3 includes a traction rope 301 and a digital display shaft 305. The adjustment mechanism 4 includes a bevel gear 401 and a displacement plate 411. The return mechanism 6 includes a return spring 604. The frame 1 has a digital display window 101 and a bar display window 102. The digital display window 101 is used to observe the numbers on the units digit display 307 and the tens digit display 309. The bar display window 102 is used to observe the length of the bar display winding 202. The traction rope 301 is fixedly connected to the winding plate 203, and the bevel gear 401 is fixedly mounted on the digital display shaft 305.

[0028] The bar display mechanism 2 also includes a damping seat 201, a bar display tape 202, and a return spring 204. The damping seat 201 is fixedly installed inside the plate frame 1. The circular portion of the bar display tape 202 is rotatably mounted on the damping seat 201. A torsion spring is provided between the bar display tape 202 and the damping seat 201. Optionally, the bar display tape 202 is a colored tape, and the color of the bar display tape 202 is red. A tape winding plate 203 is fixedly installed at the end of the bar display tape 202. One end of the return spring 204 is connected to the tape winding plate 203, and the other end of the return spring 204 is fixed to the plate frame 1.

[0029] Specifically, when the winding plate 203 moves upward, it drives the bar display winding 202 to rise, and the bar display window 102 is used to observe the rising height of the bar display winding 202; when the winding plate 203 moves downward, the bar display winding 202 is retracted and wound up under the action of the torsion spring between the bar display winding 202 and the damping seat 201.

[0030] The digital display mechanism 3 also includes a guide wheel 302, a wheel frame 303, a drum 304, a digital display frame 306, a units digit display panel 307, a notched gear 308, a tens digit display panel 309, a tens digit driven gear 310, an intermediate transmission shaft 311, a tens digit driving gear 312, and a units digit gear 313. The guide wheel 302 guides the traction rope 301 and is mounted on the wheel frame 303. The wheel frame 303 is fixed inside the plate frame 1. The other end of the traction rope 301 is wound around the drum 304, which is fixed on the digital display shaft 305. The digital display shaft 305 is rotatably mounted on the digital display frame 306, which is fixed inside the plate frame 1. A unit display is fixed in the middle of the digital display shaft 305. The unit display disk 307 has Arabic numerals "1" to "10" arranged sequentially on it. A notched gear 308 is fixedly mounted on the unit display disk 307. The tens display disk 309 is rotatably mounted on the rotating cylinder 3061 of the digital display frame 306. The tens display disk 309 has Arabic numerals "1" to "10" arranged sequentially on it. The tens driven gear 310 is fixedly mounted on the tens display disk 309. The tens driving gear 311 is rotatably mounted on the digital display frame 306. The tens driving gear 312 and the units gear 313 are fixedly mounted sequentially on the intermediate transmission shaft 311. The tens driving gear 312 and the tens driven gear 310 form a gear mesh, and the notched gear 308 and the units gear 313 form a gear mesh.

[0031] The notched gear 308 and the tens driven gear 310 have the same module and direct drive, and the number of teeth of the notched gear 308 is one-tenth of the number of teeth of the tens driven gear 310; the tens driving gear 312 and the units gear 313 have the same module, direct drive, and number of teeth.

[0032] Specifically, the digital display shaft 305 drives the units display disk 307 to rotate. When the number changes from "9" to "0", the notched gear 308 drives the units gear 313 to rotate. The units gear 313 drives the intermediate transmission shaft 311 and the tens drive gear 312 to rotate. The tens drive gear 312 drives the tens driven gear 310 to rotate one-tenth of a turn, thus achieving the effect that the units gear 313 rotates one turn and the tens drive gear 312 rotates one-tenth of a turn.

[0033] The adjusting mechanism 4 also includes a second bevel gear 402, a drive shaft 403, a third bevel gear 404, a fourth bevel gear 405, a handle 406, a handle plate 407, a pin block 408, a pin spring 409, a limit plate 410, and an adjusting spring 412. The first bevel gear 401 meshes with the second bevel gear 402. The second bevel gear 402 is fixedly mounted on one end of the drive shaft 403, and the other end of the drive shaft 403 is fixedly mounted on the third bevel gear 404. The drive shaft 403 is rotatably mounted inside the frame 1. The third bevel gear 404 meshes with the fourth bevel gear 405. The fourth bevel gear 405 is fixedly mounted on the handle 406, which is rotatably mounted on the frame 1. A handle plate 407 is provided at the end of the handle 406. Ten sliding grooves are arranged in sequence. There are two pin blocks 408. The two pin blocks 408 are symmetrically slidably arranged on the sliding groove of the handle plate 407. The pin spring 409 is located inside the sliding groove of the handle plate 407. One end of the pin spring 409 is fixedly connected to the pin block 408, and the other end of the pin spring 409 is fixedly connected to the handle plate 407. The limiting plate 410 is adapted to the handle plate 407. The limiting plate 410 is provided with ten opening slots. The pin blocks 408 are adapted to the opening slots of the limiting plate 410. The limiting plate 410 is slidably arranged on the displacement plate 411. One end of the adjusting spring 412 is connected to the displacement plate 411, and the other end of the adjusting spring 412 is fixedly connected to the limiting plate 410. The displacement plate 411 is slidably arranged on the plate frame 1.

[0034] Specifically, when the pin block 408 is inserted into the opening slot of the limiting plate 410, the handle 406 and the handle plate 407 can rotate but cannot rotate. When the displacement plate 411 moves with the limiting plate 410, causing the opening slot of the limiting plate 410 to disengage from the pin block 408, the handle 406 and the handle plate 407 can rotate freely.

[0035] The adjustment mechanism 4 also includes a branching cord 413, a bonding plate 414, a bonding cord 415, and a sliding plug 416. One end of the branching cord 413 is fixedly mounted on the pin block 408, and the other end of the branching cord 413 is fixedly connected to the bonding plate 414. The bonding plate 414 is slidably mounted in the internal cavity of the handle 406. One end of the bonding cord 415 is fixedly connected to the bonding plate 414, and the other end of the bonding plate 414 is fixedly connected to the sliding plug 416. The sliding plug 416 is slidably mounted on the handle 406.

[0036] Specifically, the movement of the piston 416 tightens the cable 415, causing the cable plate 414 to slide inside the handle 406. Power is transmitted through the cable 413 to pull the pin block 408 out of the opening slot of the limit plate 410, thereby allowing the handle 406 and the handle plate 407 to rotate.

[0037] The adjustment mechanism 4 also includes a handle rotating sleeve 417, a rotating ring 418, a drive slide plate 419, a connecting plate 420, a hand grip plate 421, and a grip plate spring 422. The handle rotating sleeve 417 is rotatably mounted on the handle 406. The rotating ring 418 is rotatably connected to the sliding plug 416. One end of the drive slide plate 419 is fixedly connected to the rotating ring 418. The other end of the drive slide plate 419 is rotatably connected to one end of the connecting plate 420. The drive slide plate 419 is slidably mounted on the handle rotating sleeve 417. The other end of the connecting plate 420 is rotatably connected to the hand grip plate 421. The hand grip plate 421 is slidably mounted on the handle rotating sleeve 417. The grip plate spring 422 is fixedly connected between the handle rotating sleeve 417 and the hand grip plate 421.

[0038] Specifically, by pinching the grip plate 421 with your hand, the grip plate 421 is brought closer to the handle swivel sleeve 417. Power is transmitted through the connecting plate 420, causing the drive slide plate 419 to move in a straight line, thereby driving the rotating ring 418 and the sliding plug 416 to be pulled out of the handle 406.

[0039] The knob reset mechanism 5 includes a knob 501, a locking strip 502, a locking platform 503, a push rod 504, a push rod slide plate 505, and a knob spring 506. The knob 501 is rotatably mounted on the plate frame 1. The end of the knob 501 is provided with a locking strip 502, which is adapted to the locking platform 503. One end of the push rod 504 is rotatably connected to the locking strip 502, and the other end of the push rod 504 is fixedly mounted on the displacement plate 411. The push rod 504 slides on the push rod slide plate 505, which is fixedly mounted inside the plate frame 1. The knob spring 506 passes through the push rod 504. One end of the knob spring 506 is fixedly connected to the push rod slide plate 505, and the other end of the knob spring 506 is fixedly connected to the displacement plate 411.

[0040] Specifically, pressing the knob 501 will drive the push rod 504 to position, thereby driving the displacement plate 411 to produce displacement; pressing and rotating the knob 501 will cause the locking strip 502 to lock onto the locking table 503, so that the displacement plate 411 will continuously produce displacement.

[0041] The top return mechanism 6 also includes a power inclined block 601, a connecting rod 602, and a top return rod 603. The middle part of the power inclined block 601 is slidably disposed inside the plate frame 1. One end of the connecting rod 602 is rotatably connected to the power inclined block 601, and the other end of the connecting rod 602 is rotatably connected to the top return rod 603. The top return rod 603 is slidably disposed inside the plate frame 1. The top return rod 603 passes through the plate frame 1. One end of the top return spring 604 is fixedly connected to the top return rod 603, and the other end of the top return spring 604 is fixedly connected to the plate frame 1. The top return spring 604 is used to drive the card bar 502 to rotate.

[0042] When the winding plate 203 descends to the bottom, the winding plate 203 acts on the power inclined block 601, causing the power inclined block 601 to move. The power is transmitted through the connecting rod 602, causing the return rod 603 to rise. The return spring 604 is compressed, and the return rod 603 acts on the locking strip 502, causing the locking strip 502 to disengage from the locking table 503.

[0043] Working principle: When data comparison needs to be displayed during teaching, the hand grip plate 421 is held and brought closer to the handle rotating sleeve 417. Power is transmitted through the connecting plate 420, causing the drive slide plate 419 to move linearly. This drives the rotating ring 418 and the sliding plug 416 to be pulled out of the handle 406. The sliding plug 416 tightens the wire connecting rope 415, causing the wire connecting plate 414 to slide inside the handle 406. Power is transmitted through the wire separating rope 413, causing the pin block 408 to be pulled out of the opening slot of the limiting plate 410. At this time, the handle 406 is rotated, which drives the fourth bevel gear 405 to rotate. The fourth bevel gear 405 drives the third bevel gear 404, the transmission shaft 403, and the second bevel gear 402 to rotate, further driving the bevel gear 401 to rotate. Therefore, the digital display shaft 305 rotates synchronously with the handle 406.

[0044] The digital display axis 305 rotates the units digit display dial 307. When the number changes from "9" to "0", the notched gear 308 drives the units digit gear 313 to rotate. The units digit gear 313 drives the intermediate transmission shaft 311 and the tens digit drive gear 312 to rotate. The tens digit drive gear 312 drives the tens digit driven gear 310 to rotate one-tenth of a turn, thus achieving the effect that the units digit gear 313 rotates one turn and the tens digit drive gear 312 rotates one-tenth of a turn. The digital display window 101 observes the numbers on the units digit display dial 307 and the tens digit display dial 309.

[0045] The digital display shaft 305 rotates the drum 304, and the drum 304 retracts the traction rope 301, so that when the winding plate 203 moves upward, the winding plate 203 drives the bar display winding 202 to rise. The bar display window 102 is used to observe the rising height of the bar display winding 202.

[0046] Reverse handle 406. Following the same principle, the units display 307 and tens display 309 rotate in the flip direction. At the same time, the digital display shaft 305 rotates the drum 304 in the opposite direction, releasing the traction rope 301. Under the action of the return spring 204, the winding plate 203 moves downward. Under the action of the torsion spring between the bar display winding 202 and the damping seat 201, the bar display winding 202 is wound up.

[0047] Therefore, the height of the numbers observed in the digital display window 101 and the height of the bar display strip 202 observed in the bar display window 102 are matched, and the size of the data can be represented by both numbers and bars, which can improve the teaching effect.

[0048] When the displayed data needs to be quickly zeroed, pressing the knob 501 will drive the push rod 504 to position, thereby driving the displacement plate 411 to move. At the same time, rotating the knob 501 will cause the locking strip 502 to lock onto the locking table 503, causing the displacement plate 411 to continuously move. The displacement plate 411 drives the limit plate 410 to move. When the opening slot of the limit plate 410 is disengaged from the pin block 408, the handle 406 and the handle plate 407 can rotate freely. Then, under the action of the reset spring 204, the winding plate 203 moves downward. Under the action of the torsion spring between the bar display winding 202 and the damping seat 201, the bar display winding 202 is wound up.

[0049] When the winding plate 203 descends to the bottom, the winding plate 203 acts on the power inclined block 601, causing the power inclined block 601 to move. The power is transmitted through the connecting rod 602, causing the return rod 603 to rise. The return spring 604 is compressed, and the return rod 603 acts on the locking strip 502, causing the locking strip 502 to disengage from the locking table 503. Then, under the action of the knob spring 506, the knob 501 is reset, the displacement plate 411 is reset, and under the action of the adjusting spring 412, the limiting plate 410 is pressed tightly against the handle plate 407, so that the pin block 408 can enter the opening slot of the limiting plate 410.
