9. The english teaching device of claim 8, wherein: the supporting plate (124) is provided with a limiting hole (128), a limiting sliding rod (126) is movably inserted in the limiting hole (128), and the limiting sliding rod (126) is fixedly arranged on the inner side wall of the supporting box (103).

10. A method of using an english teaching apparatus according to any one of claims 1 to 9, comprising the steps of:

in the teaching use process, the keyboard (2) is needed, the drawing handle (13) is drawn at the moment, the drawing handle (13) can drive the plugging plate (4) to move rightwards, and the drawing handle (13) is stopped to be drawn until the plugging plate (4) moves out of the operation groove, so that the keyboard (2) can be conveniently used, and the plugging plate (4) extending out of the plugging groove (3) can be used for storing teaching articles; after the teaching is finished, the plugging plate (4) is pushed leftwards until the plugging plate (4) is abutted against the left side wall of the plugging groove (3), and at the moment, the plugging plate (4) is used for plugging the operation groove to prevent dust from falling into the operation groove;

in the process that the blocking plate (4) moves backwards, a first full gear (104) is driven to rotate through a straight rack (102), a second rotating rod (107) and a dust sweeping roller shaft (108) are driven to rotate through a first rotating rod (105) and a transmission belt (106) by the rotation of the first full gear (104), dust on the upper surface of the blocking plate (4) can be cleaned by the rotation of the dust sweeping roller shaft (108), and therefore the dust is prevented from being stained on the object when the object is placed on the blocking plate (4);

along with the rotation of the ash sweeping roller shaft (108), dust can be swept and deposited on the right side of the ash sweeping roller shaft (108), when the second rotating rod (107) rotates, the first bevel gear (111) can be driven to rotate, the first bevel gear (111) can drive the second bevel gear (112), the third rotating rod (113) and the third bevel gear (116) to rotate in a combined mode, the third bevel gear (116) can drive the fourth bevel gear (117) to rotate, so that the missing gear (119) is driven to rotate through the fourth bevel gear (117) and the fourth rotating rod (118), as the missing gear (119) is alternately meshed with two groups of parallel tooth grooves in the ring gear (1110), the rotating of the missing gear (119) can drive the ring gear (1110) to do back-and-forth circular motion, the ring gear (1110) can drive the ash scraping plate (1112) to do back-and-forth circular motion, so that the dust can be pushed to the upper surface of the sealing plate (4) through the ash scraping plate (1112), and falls to the bottom of the supporting box (103) under the action of self weight;

when first full gear (104) rotated, can take second full gear (121) to take place to rotate, the rotation of second full gear (121) can take articulated rod (123) to move, under the effect of articulated rod (123), can take trapezoidal ash pushing plate (125) to control cyclic motion, along with trapezoidal ash pushing plate's (125) side-to-side motion, can promote outside ash hole (127) with the dust that drops to supporting box (103) bottom, thereby realize taking out of dust, avoid the dust to deposit in supporting box (103).
