Abstract
The utility model discloses an anti-curling device for fixing test papers. The anti-curling device comprises a triangular main angle clip, wherein a compression bar is rotatably arranged on the upper surface of the triangular main angle clip, the other end of the compression bar is rotatably connected with an auxiliary angle clip, a crossed rod extending towards two directions is rotatably arranged in the middle of the compression bar, an elastic clamping bar which is matched with the crossed rod in length is arranged at one end of the crossed rod, and a classified annotation bag is arranged on the upper surface of the triangular main angle clip. The anti-curling device for fixing test papers is simple in structure, test papers can be stored conveniently in a classified mode, the test papers can be prevented from being curled, people can go over for use conveniently, the clamping position can be adjusted at will, characters cannot be shielded, and learning efficiency can be improved.
Description
Technical field
The utility model relates to schooling apparatus technical field, is specifically related to the fixing reeling-preventing device of a kind of paper.
Background technology
At present, in the process of English study, having a large amount of papers need to deposit, but because the kind of paper is numerous, especially need to sum up the paper of examination point, need to classify one by one, it is just easily chaotic that paper is many like this, and on classroom, ransacing paper wastes time and energy, and affects classroom efficiency.Existing way is with multiple clips, different types of clamp for test papers got up or be placed directly in one, and paper is depositing for a long time in process like this, easily occurs curlingly, and volume face is untidy, affects student and reviews use.Have now special clamp for test papers, although can solve the curling problem of depositing, after clamping, easily block paper word, impact is reviewed and is used.
Summary of the invention
The purpose of this utility model is exactly the defect existing for prior art, provides a kind of simple in structure, facilitates test paper classifying to deposit, can prevent that paper is curling, convenient review used, and can arbitrarily adjust clip position, do not block word, the fixing reeling-preventing device of paper that can improve learning efficiency.
Its technical scheme is: paper is fixed reeling-preventing device, comprise triangle leading role folder, the upper surface of described triangle leading role folder rotates and is provided with depression bar, the other end of described depression bar is rotatably connected to auxiliary angle folder, the middle part of described depression bar is rotated and is provided with the crossbar extending to two sides, one end of described crossbar is provided with the elasticity clamping bar adapting with described crossbar length, and the upper surface of described triangle leading role folder is provided with classification annotation bag.
The middle part of described depression bar and crossbar is provided with rotating shaft.
Described depression bar and crossbar are telescopic structure.
On described triangle leading role folder and auxiliary angle folder, be equipped with holding screw.
The utility model compared with prior art, has the following advantages: simple in structure, and facilitate test paper classifying to deposit, can prevent that paper is curling, convenient review used, and can arbitrarily adjust clip position, do not block word, can improve learning efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
The specific embodiment
With reference to Fig. 1, paper is fixed reeling-preventing device, comprise that triangle leading role presss from both sides 1, described triangle leading role is pressed from both sides 1 upper surface and is rotated and be provided with depression bar 2, the other end of described depression bar 2 is rotatably connected to auxiliary angle folder 3, the middle part of described depression bar 2 is rotated and is provided with the crossbar 4 extending to two sides, and one end of described crossbar 4 is provided with the elasticity clamping bar 5 adapting with described crossbar 4 length, and described triangle leading role is pressed from both sides 1 upper surface and is provided with classification annotation bag 6.
Described depression bar 2 is provided with rotating shaft 7 with the middle part of crossbar 4.
Described depression bar 2 and crossbar 4 are telescopic structure.Can arbitrarily regulate according to paper size like this, facilitate student and teacher to use.
Described triangle leading role press from both sides 1 and auxiliary angle folder 3 on be equipped with holding screw 8.Conveniently regulate as required the angle of angle folder and it is fixed.
At the interior placement Course in English of classification annotation bag 6, facilitate student to search review.During use, first triangle leading role being pressed from both sides to 1 fixes with upper left one jiao of paper, then can press from both sides 3 by auxiliary angle is fixed on its cornerwise paper angle, also can be fixed on the paper angle in the upper right corner or the lower left corner, can arbitrarily regulate according to the needs of reviewing, prevent from blocking the word on paper, and paper is fixed, convenient review used; Certainly by triangle leading role press from both sides 1 and auxiliary angle folder 3 can according to how many random adjustings of paper, and do not injure paper.When needs are deposited, can to the upper and lower surface of multiple papers, clamp by crossbar 4 and elasticity clamping bar 5, and by triangle leading role press from both sides 1 and auxiliary angle folder 3 be separately fixed at Liang Ge foot, make crossbar 4 and depression bar 2 push down respectively the diagonal of paper, can be fixed each bight like this, effectively prevent paper deposit in process curling.
The utility model is simple in structure, facilitates test paper classifying to deposit, and can prevent that paper is curling, and convenient review used, and can arbitrarily adjust clip position, do not block word, can improve learning efficiency.
