[0020] It should be noted that the terms "first", "second", etc. in the description and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence, so that the embodiments of this application described here, based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of this application.

[0021] Reference Figure 1-Figure 3The top of the fixed plate 7 near the magnetic plate 2 is fixed with a pointer 1 for indicating the question. One side of the bottom plate 8 is fixed with a handle 5 for holding by hand by bolts. A driving component for driving the turntable 3 to rotate is provided on the upper surface of the bottom plate 8, and different question labels are respectively adsorbed on the magnetic plate 2. Then, the handle 5 is held by hand to fix the bottom plate 8, and then the turntable 3 is driven to rotate by the driving component. When the turntable 3 stops rotating, the student is asked to answer the question indicated by the pointer 1, thereby increasing the uncertainty factor of answering the question, increasing the fun of interactive answering, and making a deep impression on the students.

[0022] The gear 9 is engaged with the shaft 10, and the gear 9 is engaged with the rack 11. A pull rope 15 is bonded to one side of the rack 11, and one end of the pull rope 15 is bonded to the pull ring 17 through the fixed seat 4. The pull rope 15 is strongly pulled through the pull ring 17, and the pull rope 15 will pull the rack 11 to move. The rack 11 will drive the gear 9 to rotate by meshing with the gear 9, and the gear 9 will drive the shaft 10 to rotate, and the shaft 10 will drive the turntable 3 to rotate. When the rack 11 is disengaged from the gear 9, the turntable 3 will continue to rotate under the action of inertia due to the strong pull, so that the turntable 3 can rotate freely.

[0023] A spring 16 is welded to one side of the rack 11 in the dovetail groove 13, and the spring 16 is fixed to the fixed seat 4. The rack 11 will squeeze the spring 16 when it moves, and the rack 11 can be reset by the force of the spring 16. Fixed ribs 6 are welded on both sides of the two fixed plates 7, and the fixed ribs 6 are fixed to the base plate 8. The fixed ribs 6 can strengthen the connection between the fixed plate 7 and the base plate 8. A protective pad 14 is bonded to one side of the handle 5, and a rubber pad 12 is bonded to the bottom of the base plate 8, and the rubber pad 12 is the same length as the base plate 8. The rubber pad 12 can increase the friction when the base plate 8 is placed.

[0024] Working principle: When it is needed, different question labels are adsorbed on the magnetic plate 2 respectively, and then the handle 5 is held by hand to fix the bottom plate 8, and then the pull rope 15 is pulled vigorously through the pull ring 17. The pull rope 15 will pull the rack 11 to move, and the rack 11 will drive the gear 9 to rotate through the engagement with the gear 9, and the gear 9 will drive the shaft 10 to rotate, and the shaft 10 will drive the turntable 3 to rotate. When the rack 11 is disengaged from the gear 9, due to the strong pull at this time, the turntable 3 will continue to rotate under the action of inertia. When the turntable 3 stops rotating, the students are asked to answer the questions indicated by the pointer 1, thereby increasing the uncertainty factor of answering questions, increasing the fun of interactive answering, and making a deep impression on students.

[0025] The present invention has been described through the above embodiments. Those skilled in the art will understand that the present invention is not limited to the above embodiments, and more modifications can be made according to the teachings of the present invention. These modifications all fall within the scope of protection required by the present invention.
