When the invention is used, the letter cards 5 in different through holes 4 correspond to the through holes 8 by rotating the annular turntable 3, corresponding letters are selected by observing through the first blocking piece 34, the selected letter cards 5 are pushed forwards to fall into the bent groove 6, when the selected letter cards 5 all fall into the horizontal sliding groove 601, the plurality of letter cards 5 form a complete English word and can be read through the second blocking piece 35, and the specific operation process is as follows:

the handle 38 is rotated to make the rotating shaft 19 drive the first gear 27 to rotate, and the annular turntable 3 rotates immediately under the meshing action of the internal gear ring 26 and the first gear 27; because the rotating arm 7 blocks and the diameter of the through hole 8 is smaller than the outer diameter of the letter plate 5, when the through hole 4 rotates to coaxially correspond to the through hole 8, the letter plate 5 cannot be ejected forwards due to the blocking of the rotating arm 7, so that the rotation of the annular turntable 3 cannot be blocked by the ejected letter plate 5, and the annular turntable 3 can continuously rotate to find the letter to be selected; meanwhile, since the rotating shaft 19 is subjected to the elastic force of the first spring 25 at this time, the rotating shaft 19 is not displaced in the axial direction when it is not subjected to the axial thrust, and the push ring 29 is in press-contact with the housing 2 by the elastic force of the second spring 31, which causes a frictional force between the push ring 29 and the housing 2, and the friction plates 30 are not pressed by the flange 28 and the push ring 29, so that, when the rotating shaft 19 rotates, the push ring 29 remains stationary and the corresponding swivel arm 7 does not rotate.

When the annular turntable 3 rotates until the letter cards 5 to be selected correspond to the through holes 8, the rotation is stopped, and the handle 38 is pressed down to enable the rotating shaft 19 to slide backwards along the sliding groove 20; when the rotating shaft 19 slides backwards, the spline 24 approaches and is inserted into the spline groove 23, so that the rotating shaft 19 cannot rotate, meanwhile, the friction plate 30 is pushed by the flange 28 to approach the push ring 29 and generate pressing contact, so that the push ring 29 is pushed to move backwards, at the same time, under the action of the elastic force of the second spring 31 applied to the push ring 29 and the pushing force applied to the flange 28, the friction force between the friction plate 30 and the push ring 29 is increased, so that the push ring 29 cannot rotate, and the rotating arm 7 rotates under the transmission action of the cam groove 19 and the cam push rod 22, so that the through hole 8 is staggered with the selected letter card 5; when the through hole 8 and the through hole 4 are completely staggered, the selected letter card 5 is no longer blocked by the rotating arm 7, and the frontmost selected letter card 5 slides forwards and is pressed with the front groove wall of the inclined straight groove 602 under the action of the elastic force of the third spring 32, and at the moment, the letter card 5 is pressed on the groove wall of the inclined straight groove 602 and cannot slide down due to the elastic force of the third spring 32; gradually releasing the handle 38, the rotating shaft 19 is reset and slides forwards under the elastic force of the first spring 25, the pushing ring 29 still receives the friction force of the friction plate 30 when the rotating shaft 19 is reset and slides due to the elastic force of the second spring 31, so the rotating arm 7 generates reset rotation under the transmission action of the cam groove 19 and the cam push rod 22, the through hole 8 corresponds to the through hole 4 where the selected letter card 5 is located again, and the forefront letter card 5 pops forwards at the moment, so the rotating arm 7 is reset and rotates to stir downwards to enable the letter card 5 to be free from the elastic force of the third spring 32 and roll down along the inclined straight groove 602; referring to fig. 3, after the alphabet cards 5 roll down to the connection between the horizontal chute 601 and the inclined straight chute 602, the alphabet cards 5 lose power and stay on the conveyor belt 12 as the lower end surface of the horizontal chute 601; when the rotating shaft 19 is completely reset and popped up, the spline 24 is separated from the spline groove 23 again, at this time, the handle 38 is rotated again to enable the annular rotating disc 3 to rotate, and in the rotating process of the handle 38, the first gear 27 drives the second gear 40 to rotate through the transmission of the third gear 41, so that the second belt pulley 11 coaxially connected with the second gear 40 rotates simultaneously, and the rotation of the second belt pulley 11 can drive the conveying belt 12 and the two first belt pulleys 10 to rotate simultaneously, so that the letter cards 5 on the conveying belt 12 move leftwards along with the conveying belt 12, the next letter card 5 is ensured to roll off smoothly, and meanwhile, a plurality of letter cards 5 are sequentially and tightly arranged.

After the selected letter cards 5 are sequentially rolled onto the conveyor belt 12 and moved leftward to be closely arranged according to the above operation, the letter cards 5 are sequentially arranged on the conveyor belt 12 to form a spelled english word; meanwhile, due to the real-time deflection of the eccentric gyroscope 502, the letters on the letter cards 5 always keep the fonts upward, and the reading and the display of words are greatly facilitated.

After the word spelling is finished each time, the letter cards 5 on the conveying belt 12 need to be taken out in time, the locking nuts 16 can be loosened and the wheel shafts 13 can be dialed downwards, the two first belt pulleys 10 generate vertical relative displacement, the angle of the conveying belt 12 between the two belt pulleys deflects, meanwhile, the blocking arms 18 are pressed downwards by the downwards moving wheel shafts 13 to enable the blocking arms to rotate downwards and be attached to the lower groove walls of the outlet grooves 17 tightly, the letter cards 5 sequentially roll downwards under the action of the gravity of the letter cards and fall down through the outlet grooves 17, and the falling letter cards 5 are collected and stored.

Because a plurality of same letter cards 5 can be placed in each through hole 4 in parallel, continuous multiple word spelling can be carried out by utilizing the invention; in order to achieve a more continuous use effect without complicated disassembly and assembly operations, after spelling many times, the collected and stored alphabet cards 5 can be put into the corresponding through holes 4 of the annular turntable 3 again by using the insertion holes 37 and the alphabet card inlets 36, and the operation method comprises the following steps: the annular turntable 3 is rotated according to letters on the letter cards 5 to enable the through holes 4 corresponding to the letter cards 5 to correspond to the through holes 8, then the letter cards 5 are inserted into the letter card inlets 36 through the jacks 37 and completely enter the through holes 4 to complete installation of the letter cards 5, and the collected and stored plurality of letter cards 5 are respectively placed into the corresponding through holes 4 according to the operation method and then can be continuously used for multiple times; in order to make the installation of the letter cards 5 smoother, the outer edges of the letter cards 5 can be designed to be smooth circular arc shapes, and meanwhile, the positions of the letter card inlets 36 can be arranged between any two adjacent letter cards 5 in the same through hole 4, so that the letter cards 5 are prevented from being blocked by other existing letter cards 5 in the through hole 4 when being inserted, and the arrangement is a common technical means for solving similar problems by technical personnel in the field, and is not repeated in the specification.

The invention is used for spelling English words, so that the attention of students can be highly focused on the English letters to be found, thereby obtaining correct words, and the process is favorable for increasing the memory of the students on the words; different from the traditional writing operation, the invention needs the students to use the hands and the brains simultaneously, not only needs to determine each English letter forming the word, but also needs to select the English letters in sequence by rotating the handle, and enables each letter to fall into the bent groove in sequence by pressing the handle, and then the English letters can be consulted.

Meanwhile, compared with the boring and tedious repeated writing, the method for spelling words is a learning process and an entertainment process, and can be used as a word display teaching aid and a classroom examination tool when used in a classroom, so that teachers and classmates participate together, and the interactivity of classroom teaching is improved.
