The first unidirectional needle roller bearing 4 and the second unidirectional needle roller bearing 5 are OWC1016 type unidirectional needle roller bearings manufactured by Changzhou Li Song Tay transmission technology Co., ltd; the positioning bead 11 is a YJT 12002 stainless steel press-in ball plunger manufactured by Guangzhou Shangzhu metal product Co., ltd, the root of the positioning bead 11 extends into the adjusting rod 7, and the head of the positioning bead 11 extends into the groove 8.
When the rolling and unreeling control device is used, the rolling and unreeling control device controls the rolling and unreeling of the accommodating part by pressing the first rotating shaft 12 and the second rotating shaft 13 to enable the sliding position of the adjusting rod 7 in the sleeve 6 to be different, when the positioning beads 11 of the adjusting rod 7 are clamped in the positioning grooves 9 positioned above in the two positioning grooves 9, the upper end of the adjusting rod 7 stretches into the first one-way needle bearing 4, the lower end of the adjusting rod 7 is not contacted with the second one-way needle bearing 5, the acting force of the spring 10 on the sleeve 6 is opposite to the acting force of the spring 10 on the sleeve 6, which pulls the accommodating bag outwards, so that the sleeve 6 rotates in the same direction as the direction in which the first one-way needle bearing 4 allows the adjusting rod 7 to rotate (at the moment, the needle of the first one-way needle bearing 4 is in rolling contact with the adjusting rod 7), therefore the accommodating bag can be pulled with a little force, the accommodating bag stretches out of the elastic force of the spring 10 against the accommodating bag and the pulled part of the accommodating bag can not return into the accommodating part, (when the accommodating bag is released), namely the needle 7 of the first one-way needle bearing 4 is clamped: when the positioning bead 11 of the adjusting rod 7 is clamped in the positioning groove 9 positioned above the two positioning grooves 9, the containing part is in an unreeled state.
When the positioning beads 11 of the adjusting rod 7 are clamped in the positioning grooves 9 positioned below the two positioning grooves 9, the lower end of the adjusting rod 7 extends into the second one-way needle bearing 5, the upper end of the adjusting rod 7 is not in contact with the first one-way needle bearing 4, the acting force of the spring 10 on the sleeve 6 is opposite to the acting force of the holding bag which is pulled outwards on the sleeve 6, the tendency of the sleeve 6 to rotate is opposite to the direction in which the second one-way needle bearing 5 allows the adjusting rod 7 to rotate (at the moment, the needle of the second one-way needle bearing 5 clamps the adjusting rod 7), so that the holding bag in the holding part cannot be pulled out, but when the holding bag is loosened, the holding bag can be retracted into the holding part along with the elastic force of the spring 10, and when the holding bag is retracted into the holding part along with the elastic force of the spring 10, the needle of the second one-way needle bearing 5 is in rolling contact with the adjusting rod 7, namely: when the positioning beads 11 of the adjusting rod 7 are clamped in the positioning grooves 9 positioned below the two positioning grooves 9, the containing part is in a rolling state.
During reading, the positioning beads 11 of the adjusting rod 7 in the left accommodating part are clamped in the positioning grooves 9 positioned above in the two positioning grooves 9, the positioning beads 11 of the adjusting rod 7 in the right accommodating part are clamped in the positioning grooves 9 positioned below in the two positioning grooves 9, namely, the left accommodating part is in an unreeling state, the right accommodating part is in a reeling state, when the two accommodating parts are pulled out to two sides by hands, the accommodating bag in the left accommodating part is pulled out, after a certain length is pulled out, the accommodating bag outside the shell of the left accommodating part is pressed by the thumb of the left hand, and can not return to the accommodating part on the left side any more, reading and memorizing can be performed, when the two accommodating parts are oppositely closed, the accommodating bag between the two accommodating parts is folded in the accommodating part on the right side, and the two accommodating parts are pulled out once again, so that when the two accommodating parts are pulled out to two sides, the two accommodating parts are transferred to the accommodating part on the right side, the two accommodating parts are repeatedly pulled out to the left accommodating part, and the contrast of the two accommodating parts in the left accommodating part and the contrast to the left accommodating part can be quickly transferred to the accommodating part on the left accommodating part, and the contrast to the left accommodating part is recorded in the Chinese accommodating part.
Similarly, the positioning beads 11 of the adjusting rod 7 in the left accommodating part are clamped in the positioning grooves 9 positioned below the two positioning grooves 9, the positioning beads 11 of the adjusting rod 7 in the right accommodating part are clamped in the positioning grooves 9 positioned above the two positioning grooves 9, namely, the left accommodating part is in a winding state, the right accommodating part is in an unreeling state, the two accommodating parts are pulled apart to be close to the two accommodating parts once again, so that a part of accommodating bags can be transferred to the left accommodating parts, the two accommodating parts are pulled apart repeatedly to be close again, and the accommodating bags can be quickly transferred to the left accommodating parts.
By the method, the content needing to be memorized can be quickly referred, and the condition that the content is found one by one in a large notebook like the prior art is not needed.
When the content of the current reading needs to be reserved, the positioning beads 11 of the adjusting rods 7 of the two storage parts can be clamped in the positioning grooves 9 positioned above the two positioning grooves 9, namely, the two storage parts are in an unreeled state, the content of the current reading cannot be received in any storage part, and long-time reading and memorizing can be performed.
When not using, can be after two storage parts are close to each other with the locating bead 11 of the regulation pole 7 of two storage parts all clamps in the constant head tank 9 that is located the top in two constant head tanks 9, and two storage parts are in the unreeling state promptly, and reading position can be preserved, can not change the position, makes things convenient for the next time to continue reading and memorizing by current progress.
The control card paper 15 can be written or printed by common printing paper, and is convenient to memorize different contents after being cut, and the control card paper 15 is placed in the accommodating bag and is not easy to pollute.
The invention has the appearance similar to ancient bamboo slips or holy, has corresponding times sense with ancient Chinese, improves the recognition sense of students, has novel and convenient use mode, improves the use interest of students, ensures that the students are more willing to use the invention, correspondingly increases the use time and times after improving the use interest, has better memory effect, can improve the memory efficiency, and has the strip shape, so the content on the contrast card paper 15 is vertically written, has the same way as the ancient writing, can enable the students to more quickly develop the reading habit of the ancient literature, eliminates the reading difficulty, and is beneficial to quick reading and understanding of the content of other books.
The adjusting groove 17 can rotate the adjusting rod 7 by a screwdriver before the sealing cover 3 is connected in the assembling process, so that the tightness degree of the clockwork spring 10 can be adjusted, and the assembling is convenient.
Besides the application, the invention can assist in memorizing the contents which need to be memorized in other teaching processes such as English words, mathematical formulas and the like.
The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above examples, and various modifications can be made to the technical solution of the present invention without departing from the spirit of the present invention, i.e., the scope of the disclosure.
