Description

The cutter of the auxilliary books of compacting loose-leaf religion

Technical field

The utility model relates to the auxilliary books of a kind of religion, and auxilliary books of improved loose-leaf religion in addition on existing book-binding basis particularly, these books are very easy to using of student and to the management of class hour operation, have improved teacher comment student class hour operating efficiency.

Background technology

Along with the progress of society, the scope of one's knowledge of student's contact is more and more wider, and the course that learn is also more and more, will certainly increase the weight of academics and students's load.

At present, the auxilliary class books of the religion on the market generally all are that class hour operation part is bound into book separately or is placed on back of corresponding class hour now, like this, the volumes of books just increases greatly in student's school bag, and simultaneously, the difficulty of teacher comment student class hour operation also strengthens.With 40 students of a class is example, if homework book, what teacher will face is 40 books, also will find relevant operation part accordingly when correcting students' papers, and the repeatability of work is very big, has increased teacher's workload, and efficient is not high yet.

Given this, be necessary to seek a kind of simple to operate, easy to use and can avoid the auxilliary books of the simple religion of checking work that repeats of teacher.

Summary of the invention

The purpose of this utility model is to provide a kind of loose-leaf religion auxilliary books, these books are improved on existing bookbinding basis, the class hour operation partly taked to beat make the loose-leaf that tears use for hand after lateral opening, significantly reduce teacher and checked the repeated labor that operation is corrected, improved operating efficiency.

The purpose of this utility model also is to provide a kind of cutter of suppressing the auxilliary books of loose-leaf religion, and this cutter can be suppressed class hour operation page or leaf on the bookbinding basis, simply class hour operation page or leaf is pressed into loose-leaf.

To achieve these goals, the utility model has adopted following technical scheme:

The auxilliary books of a kind of loose-leaf religion comprise class hour operation page or leaf stapled together, and wherein, the binder edge of class hour operation page or leaf is provided with the impression of tearing as loose-leaf for class hour operation page or leaf.

Further, the back of the auxilliary books of religion is with the job management bag.

Further, but described job management bag comprises two bags of doubling, and wherein a slice bag below is stained with for the knuckle bag that holds class hour operation loose-leaf.

Further, two bags and the knuckle bag of job management bag are the paper folding that suppresses impression in advance, through the simple folding aftershaping of pasting.

A kind of cutter of suppressing the auxilliary books of loose-leaf religion, comprise the hollow wheel body and the gear teeth that are arranged on the wheel body edge, the centre of the annular wheel body at wheel body center line two ends respectively is provided with an installing hole, the gear teeth are evenly distributed on the wheel surface, the preferred 24-28 of the number of teeth, tooth depth is 4mm, and the wheel body diameter is 62mm, hollow wheel body internal diameter is 40mm, and thickness is 0.5mm.

The advantage of the auxilliary books of loose-leaf religion of the present utility model is, each teacher has a class the back when layout class hour operation, the student just with the operation of corresponding class hour along lateral opening the tearing of being beaten, the name and the class that write oneself become homework book into the use of operation paper, have so just made things convenient for teacher's correcting operation.Simultaneously, it is relatively more chaotic and designed the job management bag to finish after the operation management at the student, is attached to the back of every book.The student can obtain the job management bag after manufacturing by simple hand, and the operation paper that tears it down is placed in the management bag, has strengthened the management of operation.Mistake topic part and not yet done knowledge point to oneself can be extracted out at any time and consolidated.Both having strengthened students'ability for practice, and made things convenient for teacher to the correcting of operation again, and also be convenient to the management of student to operation, is killing three birds with one stone.

The specific embodiment

As shown in Figure 1, the auxilliary books of loose-leaf religion of the present utility model comprise class hour operation page or leaf 2 stapled together, and the binder edge of class hour operation page or leaf 2 is provided with the impression 1 of tearing as loose-leaf for class hour operation page or leaf.Preferably, has the job management bag in the back of the auxilliary books of religion.The job management bag can be any bag form of placing class hour operation paper.But preferred job management bag is two bags 3 by doubling to be constituted, and wherein a slice bag below is stained with for the knuckle bag 4 that holds class hour operation loose-leaf.Two bags 3 and the knuckle bag 4 of job management bag are the paper folding that suppresses impression in advance, through the simple folding aftershaping of pasting.Wherein, Fig. 2 shows the simple manufacture process that is attached to the job management bag behind the books.Detailed process is: at first, with the paper folding taking-up that suppresses impression in advance that is attached to after books are assisted in religion, sticking tangent line is cut out this page or leaf down along the left side shown in Fig. 2 (1), it is folding and adhesion-molded to be used to be folded into the paper folding of knuckle bag according to impression then, specifically shown in Fig. 2 (2), cut off along solid line, dotted line is folding, the whole then knuckle bag is pasted made the job management bag on the doubling bag, shown in Fig. 2 (3) sack is occupied the lower right corner up and be attached in the envelope district; The operation unification of tearing at ordinary times can be drawn together in the job management bag at last and unite, centralized management is browsed at any time.

The utility model is improved technology on existing bookbinding basis.Through repetition test, at making things convenient for hand to tear, be unlikely to the principle of diffusing page or leaf again, customized the perforating cutting tool of the impression in the auxilliary books of compacting loose-leaf religion, this cutter comprises hollow wheel body 5 and is arranged on the gear teeth 6 at wheel body edge, the centre of the annular wheel body at wheel body center line two ends respectively is provided with an installing hole 7, and the gear teeth are evenly distributed on wheel surface, the preferred 24-28 of the number of teeth, the wheel body diameter is 62mm, hollow wheel body internal diameter is 40mm, and tooth depth is 4mm, and thickness is 0.5mm.By binding device having been done the relevant art transformation, on original basis, increased the installation of the cutter of the auxilliary books impression of this compacting loose-leaf religion, thereby improved the quality and the speed of punching.

The above, it only is better embodiment of the present utility model, can not limit scope of the present utility model with this, all equivalences of doing according to the utility model claims and description change and revise, and all should belong to the scope that the utility model is contained.
