Writing wipe after again 10290 ° of rotating push-rod, blackboard brush 104 no longer contacted with 8 bottom of cylinder, then carry out it is next game,
When needing that blackboard brush 104 is replaced or cleaned, push rod 102 is moved to the left, when the first kelly 107 is caught in blackboard brush
When in second groove 106 in 104 left sides, push rod 102 is rotated counterclockwise, push rod 102, which rotates counterclockwise, drives the second bolt 103 inverse
Hour hands rotation, because the first kelly 107 blocks the second groove 106, blackboard brush 104 not can rotate, until going to blackboard
When brush 104 falls off, then blackboard brush 104 is pushed into grey leakage port 11 with push rod 102 and is fallen down from grey leakage port 11, it then can be to blackboard brush
104 are replaced.So can more convenient writing by cylinder 8 blackboard brush 104 for wiping clean, while can replacing,
So that the service life is longer for equipment.
When using this equipment, ready card 145 is put into third groove 144 first, then blocks disk 141
Enter the right side of cylinder 1, then turn third bolt 1410 and move inward and disk 141 is fixed on cylinder 1, prevents the disk in game
141 fall, and when needing to remove card 145 exchange for carrying out position, rotation third bolt 1410 is displaced outwardly, at this moment third spiral shell
Bolt 1410 no longer blocks cylinder 1, then disk 141 is removed, and then pins the second kelly 147 to 145 medial movement of card, and first
Compressed spring 148 is compressed, and 147 right end of the second kelly no longer blocks third groove 144, then 145 position of card is exchanged, and
It is stuck in corresponding third groove 144, then unclamps the second kelly 147, under the action of the first compressed spring 148, the second kelly
147 are displaced outwardly and are stuck in third groove 144, thus card 145 is fixed, then it is fixed on cylinder 1 i.e. by disk 141
It can.The position of card 145 is exchanged, can prevent student from remembeing the case where lexicographic order is answered, is preferably helped
Student study.
When carrying out the practice of letter using this equipment, user can pull downward on pull ring 20, driven and blocked by guide rod 19
Tooth 24 moves down, and the second compressed spring 22 is compressed, because latch 24 can not be rotated up, latch 24, which moves down, to be pushed away
Moving gear 17 rotates a lattice, so that the card 145 on right side just turns next, then user unclamps pull ring 20, the second compression bullet
Spring 22 resets, and drives connecting rod 21 to move up reset, so that latch 24 moves up, because having one-way clutch 16, gear
17 can not opposite direction rotation, so torque spring 23 is compressed, latch 24 when latch 24 is moved upwards up to and contacts with gear 17
It rotates down, after latch 24, which leaves gear 17, to be resetted, torque spring 23, which resets, drives latch 24 to reset, and then can be practiced
It practises, repeatedly, until practice finishes.After latch 24 is detached from gear 17, firmly reduces, the card of user right can be prompted
145 have been rotated by and finish, and can unclamp pull ring 20, such equipment is more convenient to use.It is needing simultaneously by the card 145 on right side
When rotating multiple, crank 6 can be used and rotated, user, which can according to need, to rotate.
When being wiped with blackboard brush 104 to cylinder 8, after blackboard brush 104 is rotated 180 °, push rod 102 is pushed to move right
Dynamic, the second fixture block 25 is caught in the 6th groove 26, is then rotated crank 6 and is wiped to the writing on cylinder 8, on cylinder 8
After the completion of writing wiping, push rod 102 is pulled to be moved to the left, rotating push-rod when the second kelly 147 no longer blocks six grooves 26
102, then blackboard brush 104 is rotated and is resetted.So in wiping, there is no need to the position of blackboard brush 104, user are kept with hand
It is more convenient to use.
When user pulls downward on pull ring 20 and guide rod 19 is driven to move down, guide rod 19 drives block 27 to move down, when
Block 27 is moved down into when contacting with rubber ring 29, and the beginning of third compressed spring 30 is compressed, and is moved down to guide rod 19
It is buffered, while can also further remind user, it should unclamp pull ring 20, rubber ring 29 is the after pull ring 20 unclamps
The effect of three compressed springs 30 is lower to be resetted, and the power that so can prevent user from pulling down is too big, and the second compressed spring 22 is caused to be damaged.
Although describing the present invention referring to exemplary embodiment, it should be understood that the present invention is not limited to disclosed to show
Example property embodiment.The scope of the following claims should give broadest explanation, to cover all modification and equivalent
