[0012] Preferably, the method for using the auxiliary teaching aid for financial economics teaching comprises the following steps:

[0013] S1: In the process of financial teaching, the driving motor drives the driving gear to rotate, and the driving gear rotates the transmission gear so that the driving rod can rotate. The rotation of the driving rod can make the three driving bevel gears rotate synchronously, and the three driving bevel gears and the three linear statistical mechanisms are matched with each other, so that when the driving bevel gears rotate, the corresponding linear statistical mechanisms can realize the data content to be counted, which is convenient for operators to operate and use;

[0014] S2: When the driving rod rotates under the drive of the driving motor, the driving rod drives the driving bevel gear to rotate, and the driving bevel gear drives the transmission bevel gear to rotate. At this time, the sleeve rod is driven by the elastic spring so that the sleeve rod and the rotating rod are not in a clamping state. When the operator needs to display linear statistics, the three sub-controllers correspond to the three linear statistical mechanisms. After the operator sets the value, one of the sub-controllers moves toward the bottom of the teaching aid box under the transmission of the electrical signal. The sub-controller moves downward to drive the positioning rod to move in the limit slot and the wedge-shaped slot on the adjustment plate. When the positioning rod moves downward, it contacts the wedge-shaped slot so that the adjustment plate can slide in the teaching aid box until the positioning rod moves down to the clamp on the bottom of the wedge-shaped slot. When the interface is reached, the positioning rod is engaged with the card interface, and the elastic springs arranged on the adjustment plate and the inner wall of the teaching aid box will restrict the positioning rod in the card interface, limit the positioning rod, and thus limit the corresponding sub-controller. At this time, the wedge block on the positioning rod will squeeze the sphere on the sleeve rod, so that the sleeve rod moves toward the position of the rotating rod. At this time, the sleeve rod and the rotating rod are engaged, so that when the transmission gear rotates, the rotating rod can be rotated through the sleeve rod, and the rotation of the rotating rod drives the rotating gear to rotate. The rotating gear will move the statistical rod upward in the linear statistical cylinder through the tooth groove on the statistical rod, thereby realizing the effect state of linear statistics in the linear statistical cylinder, and intuitively observing the data required for linear statistics through the movement of the statistical rod;

[0015] S3: When one of the linear statistics is finished and another set of linear statistics needs to be observed, the other sub-controller is moved down under the drive of the electrical signal. At this time, the positioning rod on the other sub-controller moves in the corresponding wedge-shaped slot and drives the adjustment plate to move again. At this time, the positioning rod in the previous wedge-shaped slot will be separated from the card interface. The sub-controller will move up and reset the previous sub-controller under the drive of the pressure spring, so that the wedge block of the previous positioning rod is no longer in contact with the ball. At this time, after the other sub-controller moves down, the positioning rod on the other sub-controller will be engaged with the card interface in the corresponding wedge-shaped slot, so that the wedge block on the other positioning rod is in contact with the ball on the corresponding linear statistical mechanism. At this time, when the driving rod rotates, the driving bevel gear on the driving rod will drive the statistical rod on the other linear statistical mechanism to move toward the linear statistical cylinder, so as to demonstrate another data. Through this setting, the operator can control different data for demonstration, which improves the convenience in the teaching process. The demonstration switching of different linear statistical mechanisms can be realized through the sub-controller, and the convenience of operation is effectively improved;

[0016] S4: When the electrical signal controls the main controller to move downward, the positioning rod on the main controller contacts the corresponding wedge-shaped slot, which drives the adjustment plate to move, thereby releasing the limit of the positioning rod on the adjustment plate that is engaged by the card interface. Since the wedge-shaped slot corresponding to the positioning rod on the main controller is not provided with a card interface, when the positioning rod moves downward and the engaged positioning rod is released from the limit, the main controller will rise under the action of the pressure spring. At this time, the main controller and the sub-controller will be at the top of the teaching box at the same time, which is convenient for the operator to control.

[0017] S5: When the driving rod rotates to drive the linear statistics mechanism to display the linear statistics, the driving rod rotates to synchronously rotate the moving bevel gear, and the moving bevel gear rotates to make the annular bevel gear drive the rotating cylinder to rotate. The mounting opening on the moving frame is provided with a disassembly-set chalk. When the rotating cylinder rotates, the moving frame rotates around the circumference of the rotating cylinder, and the chalk on the moving frame is smeared around the display card disk in an annular manner;

[0018] S6: When one of the sub-controllers performs linear statistics, the rotating cylinder rotates to make the chalk on the mobile frame apply in a circular shape around the display card disk, and when the other sub-controller performs the next set of linear statistics, the sub-controller moves downward to move the adjustment plate toward the direction of the large gear, and the adjustment tooth plate on the adjustment plate drives the large gear to rotate. The transmission ratio between the large gear and the small gear makes the small gear rotate 180 degrees, and the small gear drives the adjustment cylinder to rotate. When the adjustment cylinder rotates, the arc-shaped slide groove provided on the adjustment cylinder drives the card rod to extend the adjustment rod toward the rotating cylinder. At this time, the limit frames at the ends of the two adjustment rods will move toward the end face of the rotating cylinder. Because the adjustment frame is rotatably arranged on the limit frame, when the limit frame moves, the adjustment frame can be pushed toward the direction of the rotating cylinder, and the rifle rod on the adjustment frame will rotate the adjustment gear, and the adjustment gear will drive the teeth on the mobile frame to move the mobile frame on the end face of the rotating cylinder. At this time, the chalk located in the installation port on the mobile frame will move toward the center of the circle of the end face of the rotating cylinder, thereby marking the display card disk.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] In the present invention, when the driving rod rotates under the drive of the driving motor, the driving rod drives the driving bevel gear to rotate, and the driving bevel gear drives the transmission bevel gear to rotate. At this time, the sleeve rod is driven by the elastic spring so that the sleeve rod and the rotating rod are not in a clamping state. When the operator needs to display linear statistics, the three sub-controllers correspond to the three linear statistical mechanisms. After the operator sets the numerical value, one of the sub-controllers moves toward the bottom of the teaching aid box under the conduction of the electrical signal. The sub-controller moves downward to drive the positioning rod to move in the limit groove and the wedge-shaped groove on the adjustment plate. When the positioning rod moves downward, it contacts the wedge-shaped groove so that the adjustment plate can slide in the teaching aid box until the positioning rod moves down to the bottom of the wedge-shaped groove. When at the card interface, the positioning rod is carded with the card interface, and the elastic springs arranged on the adjustment plate and the inner wall of the teaching box will restrict the positioning rod in the card interface, limit the positioning rod, and thus limit the corresponding sub-controller. At this time, the wedge block on the positioning rod will squeeze the sphere on the sleeve rod, so that the sleeve rod moves toward the position of the rotating rod. At this time, the sleeve rod and the rotating rod are carded, so that when the transmission gear rotates, the rotating rod can be rotated through the sleeve rod. The rotation of the rotating rod drives the rotating gear to rotate, and the rotating gear will move the statistical rod upward in the linear statistical cylinder through the tooth groove on the statistical rod, thereby realizing the effect state of linear statistics in the linear statistical cylinder, and the data required for linear statistics can be intuitively observed through the movement of the statistical rod.

[0021] In the present invention, when one of the linear statistics is completed and another set of linear statistics needs to be observed, the other sub-controller is moved downward under the drive of the electrical signal. At this time, the positioning rod on the other sub-controller moves in the corresponding wedge-shaped slot and drives the adjustment plate to move again. At this time, the positioning rod in the previous wedge-shaped slot will be separated from the card interface, and the sub-controller will move the previous sub-controller upward and reset under the drive of the pressure spring, so that the wedge block of the previous positioning rod is no longer in contact with the ball. At this time, after the other sub-controller moves downward, the positioning rod on the other sub-controller will be engaged with the card interface in the corresponding wedge-shaped slot, so that the wedge block on the other positioning rod will contact the ball on the correspondingly set linear statistical mechanism. At this time, when the driving rod rotates, the driving bevel gear on the driving rod will drive the statistical rod on the other linear statistical mechanism. It moves toward the linear statistical cylinder to demonstrate another data. Through this setting, the operator can control different data for demonstration, which improves the convenience in the teaching process. The demonstration switching of different linear statistical mechanisms can be realized through the sub-controller, and the convenience of operation is effectively improved. When the electric signal controls the main controller to move downward, the positioning rod on the main controller contacts the corresponding wedge-shaped slot, which will drive the adjustment plate to move, and then the positioning rod on the adjustment plate that is clamped by the card interface is released from the limit. Since the wedge-shaped slot corresponding to the positioning rod on the main controller is not provided with a card interface, when the positioning rod moves downward and the clamped positioning rod is released from the limit, the main controller will rise under the action of the pressure spring. At this time, the main controller and the sub-controller will be at the top of the teaching box at the same time, which is convenient for the operator to control.

[0022] In the present invention, when the driving rod rotates to drive the linear statistical mechanism to display linear statistics, the rotation of the driving rod will synchronously rotate the mobile bevel gear, and the rotation of the mobile bevel gear causes the annular bevel gear to drive the rotating cylinder to rotate. A disassembly-mounted chalk is provided in the mounting opening on the mobile frame. When the rotating cylinder rotates, the mobile frame will rotate around the circumference of the rotating cylinder, and the chalk on the mobile frame will be smeared in a circular shape around the display card disk. Therefore, when the linear statistical mechanism performs linear statistics on the data, the annular statistics of the data can be displayed on the display card disk. The two expressions of annular statistics and linear statistics can more intuitively display the data.

[0023] In the present invention, when one of the sub-controllers performs linear statistics, the rotating cylinder rotates to make the chalk on the moving frame smear in a circular shape around the display card disk, and when the other sub-controller performs the next group of linear statistics, the sub-controller moves downward to make the adjustment plate move toward the direction of the large gear, and the adjustment tooth plate on the adjustment plate drives the large gear to rotate. The transmission ratio between the large gear and the small gear makes the small gear rotate 180 degrees, and the small gear drives the adjustment cylinder to rotate. When the adjustment cylinder rotates, the arc-shaped slide groove arranged on the adjustment cylinder drives the card rod to extend the adjustment rod toward the rotating cylinder. At this time, the limit frames at the ends of the two adjustment rods will move toward the end surface of the rotating cylinder. Because the adjustment frame is rotated and arranged on the limit frame, when the limit frame moves When the gear is moved, the adjustment frame can be pushed toward the direction of the rotating cylinder, and the rifle rod on the adjustment frame can rotate the adjustment gear, and the adjustment gear can drive the teeth on the mobile frame to make the mobile frame move on the end face of the rotating cylinder. At this time, the chalk located in the installation port on the mobile frame will move toward the center of the circle of the end face of the rotating cylinder, thereby marking the display card disk, so that when the first linear statistics is switched to the second linear statistics, the display card disk can be marked, and when the switching is driven by the sub-controller, the adjustment plate is moved, and the adjustment plate adjusts the chalk on the mobile frame through the adjustment member, so that the chalk can be marked, thereby realizing the synchronous marking of the circular statistics when the linear statistics are switched, thereby improving the practicability of teaching.

The two ends of the elastic spring 39 are respectively connected to the transmission bevel gear 38 and the ball 37, and the transmission bevel gear 38 is meshed with the driving bevel gear 25;

[0040] The control mechanism 4 includes a main controller 41 and three sub-controllers 42 which are slidably arranged on the top of the teaching tool box 1. The main controller 41 and the three sub-controllers 42 are arranged at equal intervals on the top of the teaching tool box 1. The main controller 41 and the three sub-controllers 42 are electrically connected to each other and are provided with electrical signals. The three sub-controllers 42 are correspondingly arranged on the sides of the three linear statistical mechanisms 3. The main controller 41 and the three sub-controllers 42 are sleeved with pressure springs 43, and the pressure springs 43 are connected to the inner bottom of the teaching tool box 1. The inner wall of the teaching tool box 1 An adjustment plate 44 is provided on the upper sliding surface, and a tension spring 45 is connected between the adjustment plate 44 and the inner wall of the teaching aid box 1. The outer wall of the teaching aid box 1 facing the adjustment plate 44 is provided with limit grooves 46 corresponding to the main controller 41 and the three sub-controllers 42 at equal intervals. The adjustment plate 44 is provided with wedge-shaped card grooves 47 corresponding to the limit grooves 46.

[0041] A card interface 471 is provided in a wedge-shaped card slot 47 provided on the adjustment plate 44 toward the three sub-controllers 42, and a wedge-shaped block 49 is provided at one end of the positioning rod 48 on the sub-controller 42 away from the wedge-shaped card slot 47, and the wedge-shaped block 49 abuts against the ball 37 on the corresponding sleeve rod 36;

[0042] When the driving rod 23 rotates under the drive of the driving motor 21, the driving rod 23 drives the driving bevel gear 25 to rotate, and the driving bevel gear 25 drives the transmission bevel gear 38 to rotate. At this time, the sleeve rod 36 is driven by the elastic spring 39 so that the sleeve rod 36 and the rotating rod 34 are not in a locked state. When the operator needs to display linear statistics, the three sub-controllers 42 correspond to the three linear statistical mechanisms 3. After the operator sets the numerical value, one of the sub-controllers 42 moves toward the bottom of the teaching aid box 1 under the transmission of the electrical signal. The sub-controller 42 moves downward to drive the positioning rod 48 to move in the limit groove 46 and the wedge-shaped groove 47 on the adjustment plate 44. When the positioning rod 48 moves downward, it contacts the wedge-shaped groove 47 so that the adjustment plate 44 can slide in the teaching aid box 1 until the positioning rod 48 moves down to the card interface 471 at the bottom of the wedge-shaped groove 47.

At this time, the wedge block 49 on the positioning rod 48 will squeeze the ball 37 on the sleeve rod 36, so that the sleeve rod 36 moves toward the position of the rotating rod 34. At this time, the sleeve rod 36 and the rotating rod 34 are engaged, so that when the transmission gear 24 rotates, the rotating rod 34 can be rotated through the sleeve rod 36, and the rotation of the rotating rod 34 drives the rotating gear 35 to rotate. The rotating gear 35 will move the statistical rod 32 upward in the linear statistical cylinder 31 through the tooth groove 33 on the statistical rod 32, so as to realize the effect state of linear statistics in the linear statistical cylinder 31, and the data required for linear statistics can be intuitively observed through the movement of the statistical rod 32;

[0043] When one of the linear statistics is completed and another set of linear statistics needs to be observed, the other sub-controller 42 is moved down under the drive of the electrical signal. At this time, the positioning rod 48 on the other sub-controller 42 moves in the corresponding wedge-shaped slot 47, which will drive the adjustment plate 44 to move again. At this time, the positioning rod 48 in the previous wedge-shaped slot 47 will be separated from the card interface 471, and the sub-controller 42 will move up and reset the previous sub-controller 42 under the drive of the pressure spring 43, so that the wedge block 49 of the previous positioning rod 48 is no longer in contact with the ball 37. At this time, after the other sub-controller 42 moves down, the positioning rod 48 on the other sub-controller 42 will be engaged with the card interface 471 in the corresponding wedge-shaped slot 47, so that the wedge block 49 on the other positioning rod 48 is in contact with the ball 37 on the corresponding linear statistical mechanism 3. At this time, when the driving rod 23 rotates, the driving bevel gear 25 on the driving rod 23 will drive the statistics on the other linear statistical mechanism 3 The meter rod 32 moves toward the linear statistical cylinder 31 to demonstrate another data. Through this setting, the operator can control different data for demonstration, which improves the convenience of the teaching process. The demonstration switching of different linear statistical mechanisms 3 can be realized through the sub-controller 42, and the convenience of operation is effectively improved. When the electrical signal controls the main controller 41 to move downward, the positioning rod 48 on the main controller 41 contacts the corresponding wedge-shaped card slot 47, which will drive the adjustment plate 44 to move, and then the positioning rod 48 on the adjustment plate 44 that is clamped by the card interface 471 is released from the limit. Since the wedge-shaped card slot 47 corresponding to the positioning rod 48 on the main controller 41 is not provided with a card interface 471, when the positioning rod 48 moves downward and the clamped positioning rod 48 is released from the limit, the main controller 41 will rise under the action of the pressure spring 43. At this time, the main controller 41 and the sub-controller 42 will be at the top of the teaching aid box 1 at the same time, which is convenient for the operator to control.

[0045] When the driving rod 23 rotates, it drives the linear statistics mechanism 3 to display linear statistics. The rotation of the driving rod 23 will synchronously rotate the mobile bevel gear 53. The rotation of the mobile bevel gear 53 causes the annular bevel gear 52 to drive the rotating cylinder 51 to rotate. The mounting port 56 on the mobile frame 55 is provided with a disassembly-mounted chalk. When the rotating cylinder 51 rotates, the mobile frame 55 will rotate around the circumference of the rotating cylinder 51. The chalk on the mobile frame 55 will be smeared in a circular shape around the display card disk 54. Therefore, when the linear statistics mechanism 3 performs linear statistics on the data, the annular statistics of the data can be displayed on the display card disk 54. The two expressions of annular statistics and linear statistics can more intuitively display the data.

[0046] In this embodiment, Figure 1 , Figure 8 , Fig. 9 and Fig.10 As shown, the annular statistical mechanism 5 also includes an adjusting member 6 arranged on the teaching tool box 1, and the adjusting member 6 includes an adjusting cylinder 61 rotatably arranged on the inner wall of the teaching tool box 1, and the outer wall of the adjusting cylinder 61 is provided with a corresponding arc-shaped slide groove 611 and a vertical groove 612, and the arc-shaped slide groove 611 and the vertical groove 612 are connected. The inner wall of the teaching tool box 1 is provided with adjusting rods 62 on opposite sides of the adjusting cylinder 61, and the adjusting rod 62 is provided with a clamping rod 63 extending in the direction of the adjusting cylinder 61. The clamping rod 63 is in sliding contact with the arc-shaped slide groove 611 and the vertical groove 612. The adjusting rod 62 is also sleeved with a connecting spring 64. The two ends of the connecting spring 64 are respectively connected to the inner wall of the teaching aid box 1 and the adjusting rod 62. A small gear 65 is fixedly provided on the outer wall of the adjusting cylinder 61. A large gear 66 meshing with the small gear 65 is rotatably provided on the inner wall of the teaching aid box 1. The adjusting plate 44 is extended toward the direction of the large gear 66 and is provided with an adjusting tooth plate 67, and the adjusting tooth plate 67 is meshed with the large gear 66.

[0047] The two adjusting rods 62 both extend toward the inside of the rotating cylinder 51, and the ends of the two adjusting rods 62 are fixedly connected to the limiting frame 68, and the limiting frame 68 is provided with an annular groove 681. The end of the rotating cylinder 51 facing the display card disk 54 is fixedly connected to a limiting rod 69 arranged oppositely, and the two limiting rods 69 are slidably provided with an adjusting frame 610, and the adjusting frame 610 is snap-fitted into the annular groove 681 on the limiting frame 68. The adjusting frame 610 is fixedly provided with a rifle rod 6101, and the rotating cylinder 51 is provided with an adjusting gear 6102 rotatably provided on the end surface of the moving frame 55, and the adjusting gear 6102 is provided with a spiral line matched with the rifle rod 6101, and the moving frame 55 is provided with teeth 6103 meshing with the adjusting gear 6102;

[0048] When one of the sub-controllers 42 performs linear statistics, the rotating cylinder 51 rotates to make the chalk on the moving frame 55 smear in a circle around the display card disk 54, and when the other sub-controller 42 performs the next set of linear statistics, the sub-controller 42 moves down to make the adjustment plate 44 move toward the direction of the large gear 66, and the adjustment tooth plate 67 on the adjustment plate 44 drives the large gear 66 to rotate. The transmission ratio between the large gear 66 and the small gear 65 makes the small gear 65 rotate 180 degrees, and the small gear 65 drives the adjustment cylinder 61 to rotate. When the adjustment cylinder 61 rotates, the arc-shaped slide groove 611 set on the adjustment cylinder 61 drives the card rod 63 to extend the adjustment rod 62 toward the rotating cylinder 51. At this time, the limit frames 68 at the ends of the two adjustment rods 62 will move toward the end surface of the rotating cylinder 51. Because the adjustment frame 610 is rotated and set on the limit frame 68, when the limit frame 6 When the adjusting plate 44 is driven by the sub-controller 42, the adjusting plate 44 moves, and the adjusting plate 44 adjusts the chalk on the movable frame 55 through the adjusting member 6, so that the chalk can be marked, thereby realizing synchronous marking of the circular statistics when the linear statistics are switched to the second linear statistics.

[0049] The use method and advantages of the present invention: The use method of the auxiliary teaching aid for financial economics teaching, the working process is as follows:

[0050] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 As shown:

[0051] S1: During the financial teaching process, the driving motor 21 drives the driving gear 22 to rotate, and the driving gear 22 rotates the transmission gear 24 so that the driving rod 23 can rotate. The rotation of the driving rod 23 can make the three driving bevel gears 25 rotate synchronously, and the three driving bevel gears 25 are in transmission cooperation with the three linear statistical mechanisms 3, so that when the driving bevel gears 25 rotate, the corresponding linear statistical mechanisms 3 can realize the data content to be counted, which is convenient for operators to operate and use;

[0052] S2: When the driving rod 23 rotates under the drive of the driving motor 21, the driving rod 23 drives the driving bevel gear 25 to rotate, and the driving bevel gear 25 drives the transmission bevel gear 38 to rotate. At this time, the sleeve rod 36 is driven by the elastic spring 39 so that the sleeve rod 36 and the rotating rod 34 are not in a clamping state. When the operator needs to display linear statistics, the three sub-controllers 42 correspond to the three linear statistical mechanisms 3. After the operator sets the value, one of the sub-controllers 42 moves toward the bottom of the teaching aid box 1 under the transmission of the electrical signal. The sub-controller 42 moves downward to drive the positioning rod 48 to move in the limit groove 46 and the wedge-shaped clamping groove 47 on the adjustment plate 44. When the positioning rod 48 moves downward, it contacts the wedge-shaped clamping groove 47 so that the adjustment plate 44 can slide in the teaching aid box 1 until the positioning rod 48 moves down to the clamping interface 471 at the bottom of the wedge-shaped clamping groove 47. The positioning rod 48 is engaged with the card interface 471, and the elastic spring 39 provided on the adjustment plate 44 and the inner wall of the teaching aid box 1 will restrict the positioning rod 48 in the card interface 471, and limit the positioning rod 48, so that the corresponding sub-controller 42 is limited. At this time, the wedge block 49 on the positioning rod 48 will squeeze the ball 37 on the sleeve rod 36, so that the sleeve rod 36 moves toward the position of the rotating rod 34. At this time, the sleeve rod 36 and the rotating rod 34 are engaged, so that when the transmission gear 24 rotates, the rotating rod 34 can be rotated through the sleeve rod 36, and the rotation of the rotating rod 34 drives the rotating gear 35 to rotate. The rotating gear 35 will move the statistical rod 32 upward in the linear statistical cylinder 31 through the tooth groove 33 on the statistical rod 32, so as to realize the effect state of linear statistics in the linear statistical cylinder 31, and the data required for linear statistics can be intuitively observed through the movement of the statistical rod 32;

[0053] S3: When one of the linear statistics is finished and another set of linear statistics needs to be observed, the other sub-controller 42 is moved down under the drive of the electrical signal. At this time, the positioning rod 48 on the other sub-controller 42 moves in the corresponding wedge-shaped card slot 47, which will drive the adjustment plate 44 to move again. At this time, the positioning rod 48 in the previous wedge-shaped card slot 47 will be separated from the card interface 471. The sub-controller 42 will move up and reset the previous sub-controller 42 under the drive of the pressure spring 43, so that the wedge block 49 of the previous positioning rod 48 is no longer in contact with the ball 37. At this time, after the other sub-controller 42 moves down, the positioning rod 48 on the other sub-controller 42 The rod 48 will be engaged with the card interface 471 in the corresponding wedge-shaped card slot 47, so that the wedge block 49 on the other positioning rod 48 will contact the ball 37 on the corresponding linear statistical mechanism 3. At this time, when the driving rod 23 rotates, the driving bevel gear 25 on the driving rod 23 will drive the statistical rod 32 on the other linear statistical mechanism 3 to move toward the linear statistical cylinder 31, so as to demonstrate another data. Through this setting, the operator can control different data for demonstration, which improves the convenience of the teaching process. The demonstration switching of different linear statistical mechanisms 3 can be realized through the sub-controller 42, and the convenience of operation is effectively improved.

[0054] S4: When the electrical signal controls the main controller 41 to move downward, the positioning rod 48 on the main controller 41 contacts the corresponding wedge-shaped slot 47, which drives the adjustment plate 44 to move, thereby releasing the limit of the positioning rod 48 engaged by the card interface 471 on the adjustment plate 44. Since the wedge-shaped slot 47 corresponding to the positioning rod 48 on the main controller 41 is not provided with a card interface 471, when the positioning rod 48 moves downward and the engaged positioning rod 48 is released from the limit, the main controller 41 will rise under the action of the pressure spring 43. At this time, the main controller 41 and the sub-controller 42 will be at the top of the teaching aid box 1 at the same time, which is convenient for the operator to control.

[0055] S5: When the driving rod 23 rotates to drive the linear statistics mechanism 3 to display the linear statistics, the driving rod 23 rotates to synchronously rotate the moving bevel gear 53, and the moving bevel gear 53 rotates to make the annular bevel gear 52 drive the rotating cylinder 51 to rotate. The mounting opening 56 on the moving frame 55 is provided with a disassembled chalk. When the rotating cylinder 51 rotates, the moving frame 55 rotates around the circumference of the rotating cylinder 51, and the chalk on the moving frame 55 is smeared in an annular manner around the display card disk 54;

[0056] S6: When one of the sub-controllers 42 performs linear statistics, the rotating cylinder 51 rotates to make the chalk on the moving frame 55 smear in a circular manner around the display card disk 54, and when the other sub-controller 42 performs the next set of linear statistics, the sub-controller 42 moves downward to make the adjustment plate 44 move toward the direction of the large gear 66, and the adjustment tooth plate 67 on the adjustment plate 44 drives the large gear 66 to rotate. The transmission ratio between the large gear 66 and the small gear 65 makes the small gear 65 rotate 180 degrees, and the small gear 65 drives the adjustment cylinder 61 to rotate. When the adjustment cylinder 61 rotates, the arc-shaped slide groove 611 set on the adjustment cylinder 61 drives the clamping rod 63 to make the adjustment rod 62 move toward the rotating cylinder 51, at this time, the limit frames 68 at the ends of the two adjusting rods 62 will move toward the end surface of the rotating cylinder 51. Because the adjusting frame 610 is rotatably set on the limit frame 68, when the limit frame 68 moves, the adjusting frame 610 can be pushed toward the direction of the rotating cylinder 51, and the rifle rod 6101 on the adjusting frame 610 will cause the adjusting gear 6102 to rotate, and the adjusting gear 6102 will drive the teeth 6103 on the moving frame 55 to move the moving frame 55 on the end surface of the rotating cylinder 51. At this time, the chalk on the moving frame 55 located in the installation port 56 will move toward the center of the end surface of the rotating cylinder 51, thereby marking the display card disk 54 by scribing.

The rotation of the driving rod (23) causes the three driving bevel gears (25) to rotate synchronously, and the three driving bevel gears (25) and the three linear statistical mechanisms (3) are in transmission cooperation, so that when the driving bevel gears (25) rotate, the correspondingly arranged linear statistical mechanisms (3) realize the data content to be counted, which is convenient for operators to operate and use; S2: When the driving rod (23) is rotated under the drive of the driving motor (21), the driving rod (23) drives the driving bevel gear (25) to rotate, and the driving bevel gear (25) drives the transmission bevel gear (38) to rotate. At this time, the sleeve rod (36) is driven by the elastic spring (39) so that the sleeve rod (36) and the rotating rod (34) are not in a locked state. When the operator needs to display linear statistics, the three sub-controllers (42) correspond to the three linear statistics mechanisms (3), and the operator sets the number. After the value is set, one of the sub-controllers (42) moves toward the bottom of the teaching aid box (1) under the conduction of the electrical signal, and the sub-controller (42) moves downward to drive the positioning rod (48) to move in the limit groove (46) and the wedge-shaped card groove (47) on the adjustment plate (44). When the positioning rod (48) moves downward, it contacts the wedge-shaped card groove (47) so that the adjustment plate (44) can slide in the teaching aid box (1), until the positioning rod (48) moves downward to the card interface (471) on the bottom of the wedge-shaped card groove (47).

At this time, the wedge block (49) on the positioning rod (48) will squeeze the ball (37) on the sleeve rod (36), so that the sleeve rod (36) moves toward the position of the rotating rod (34). At this time, the sleeve rod (36) and the rotating rod (34) are in contact with each other.

The rotating gear (35) causes the counting rod (32) to move upward in the linear counting cylinder (31) through the tooth groove (33) on the counting rod (32), thereby realizing the effect state of linear statistics in the linear counting cylinder (31), and intuitively observing the data required for linear statistics through the movement of the counting rod (32); S3: When one of the linear statistics is completed and another set of linear statistics needs to be observed, the other sub-controller (42) is moved downward under the drive of the electrical signal. At this time, the positioning rod (48) on the other sub-controller (42) moves in the corresponding wedge-shaped card slot (47), which drives the adjustment plate (44) to move again. At this time, the positioning rod (48) in the previous wedge-shaped card slot (47) is separated from the card interface (471). The sub-controller (42) is driven by the pressure spring (43) to move the previous sub-controller (42) upward and reset, so that the wedge block (49) of the previous positioning rod (48) is no longer in contact with the ball (37).

The demonstration switching of different linear statistical mechanisms (3) can be realized through the sub-controller (42), and the convenience of operation is effectively improved; S4: When the electrical signal controls the main controller (41) to move downward, the positioning rod (48) on the main controller (41) contacts the corresponding wedge-shaped slot (47), which drives the adjustment plate (44) to move, thereby releasing the limit of the positioning rod (48) engaged by the locking interface (471) on the adjustment plate (44). Since the wedge-shaped slot (47) corresponding to the positioning rod (48) on the main controller (41) is not provided with a locking interface (471), when the positioning rod (48) moves downward and the engaged positioning rod (48) is released, the main controller (41) is lifted under the action of the pressure spring (43).

The driving rod (23) rotates, which synchronously causes the moving bevel gear (53) to rotate. The moving bevel gear (53) rotates, which causes the annular bevel gear (52) to drive the rotating cylinder (51) to rotate. A detachable chalk is arranged in the mounting opening (56) on the moving frame (55). When the rotating cylinder (51) rotates, the moving frame (55) rotates around the circumference of the rotating cylinder (51). The chalk on the moving frame (55) is smeared in an annular shape around the display card disk (54). S6: When one of the sub-controllers (42) performs linear statistics, the rotating cylinder (51) rotates to make the chalk on the movable frame (55) smear in a circular manner around the display card plate (54), and when the other sub-controller (42) performs the next set of linear statistics, the sub-controller (42) moves downward to make the adjustment plate (44) move toward the direction of the large gear (66), and the adjustment tooth plate (67) on the adjustment plate (44) drives the large gear (66) to rotate. The transmission ratio between the large gear (66) and the small gear (65) causes the small gear (65) to rotate 180 degrees, and the small gear (65) drives the adjustment cylinder (61) to rotate. When the adjustment cylinder (61) rotates, the arc-shaped slide groove (611) provided on the adjustment cylinder (61) drives the clamping rod (63) to make the adjustment rod (62) move toward the rotating cylinder. (51), at this time, the limit frames (68) at the ends of the two adjustment rods (62) will move toward the end surface of the rotating cylinder (51). Since the adjustment frame (610) is rotatably arranged on the limit frame (68), when the limit frame (68) moves, the adjustment frame (610) can be pushed toward the direction of the rotating cylinder (51), and the rifle rod (6101) on the adjustment frame (610) will cause the adjustment gear (6102) to rotate, and the adjustment gear (6102) will drive the teeth (6103) on the moving frame (55) to move the moving frame (55) on the end surface of the rotating cylinder (51). At this time, the chalk on the moving frame (55) located in the installation opening (56) will move toward the center of the end surface of the rotating cylinder (51), so as to mark the display card disk (54) by marking.
