The learning time of students is delayed, many inconvenience is brought to students.
（Three）The content of the invention
The utility model is in order to make up the deficiencies in the prior art, there is provided a kind of simple in construction, easy to use, fixation
Reliably, accurate indicating bookmark applied widely.
The utility model is achieved by the following technical solution：
A kind of accurate indicating bookmark, including bottom plate, bottom plate are provided with bar, it is characterized in that：It is inserted with the bottom plate
The expansion plate that can be moved along bottom plate, bottom plate lower end left side are connected with two left support frames, two are connected with the right side of bottom plate lower end
Right support frame, two left expansion brackets are connected with the left of expansion plate upper end, are connected with two right expansion brackets on the right side of expansion plate upper end, two
Individual left expansion bracket inserts in corresponding two left support frames respectively, and two right expansion brackets insert corresponding two right support frames respectively
It is interior, screw rod is respectively equipped between two left support frames and between two right support frames, screw rod is provided with fixing nut.
The left support frame is installed on left column, and right support frame is installed on right column, and left expansion bracket is installed on left vertical
On bar, right expansion bracket is installed in right vertical rod.
Bottom plate upper end both sides are provided with the clamping screw for being used for fixing expansion plate.
Graduation mark is respectively equipped with the left expansion bracket and right expansion bracket.
The beneficial effects of the utility model are：The number of pages of last time reading can be not only found, can also find last time reading
Line number, suitable for the books of a variety of sizes；It is simple in construction, easy to use, fixation is reliable, bar will not be made to be put for a long time
Entanglement when putting, the learning time of students is greatlyd save, improve the learning efficiency of student.
（Four）Brief description of the drawings
The utility model is further described below in conjunction with the accompanying drawings.
Accompanying drawing 1 is structural representation of the present utility model；
In figure, 1 bottom plate, 2 bars, 3 expansion plates, 4 left support frames, 5 right support frames, 6 left expansion brackets, 7 right expansion brackets, 8
Screw rod, 9 fixing nuts, 10 left columns, 11 right columns, 12 left vertical rods, 13 right vertical rods, 14 clamping screws, 15 graduation marks.
（Five）Embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.The embodiment includes bottom plate 1, and bottom plate 1 is provided with bar
2, the expansion plate 3 that can be moved along bottom plate 1 is inserted with bottom plate 1, two left support frames 4, bottom plate are connected with the left of the lower end of bottom plate 1
Two right support frames 5 are connected with the right side of 1 lower end, two left expansion brackets 6 are connected with the left of the upper end of expansion plate 3, the upper end of expansion plate 3 is right
Side is connected with two right expansion brackets 7, two left expansion brackets 6 insert respectively corresponding in two left support frames 4, two right expansion brackets
7 respectively corresponding to insertion in two right support frames 5, spiral shell is respectively equipped between two left support frames 4 and between two right support frames 5
Bar 8, screw rod 8 are provided with fixing nut 9.Left support frame 4 is installed on left column 10, and right support frame 5 is installed on right column 11,
Left expansion bracket 6 is installed in left vertical rod 12, and right expansion bracket 7 is installed in right vertical rod 13.The upper end both sides of bottom plate 1, which are provided with, to be used to fix
The clamping screw 14 of expansion plate 3.Graduation mark 15 is respectively equipped with left expansion bracket 6 and right expansion bracket 7.
Using a kind of accurate indicating bookmark of the present utility model, left column 10 makes left support frame 4 hanging, and right column 11 makes the right side
Support frame 5 is hanging, and left vertical rod 12 makes left expansion bracket 6 hanging, and right vertical rod 13 makes right expansion bracket 7 hanging, in this way, just making left support frame
4th, right support frame 5, left expansion bracket 6 and right expansion bracket 7 reserve space between bottom plate 1 respectively, by this space by the book read
Last page inserts, and then moves up and down bar 2, bar 2 is placed in last column of the last page for the book read, so
After tighten fixing nut 9, you can screw rod 8 is tightly pushed down bar 2, fixed is solid and reliable, will not loosen.Fixing nut 9
Diameter is more than distance between two left expansion brackets 6, and also greater than distance between two right expansion brackets 7, i.e. it is left to be also movable to two for bar 2
Between 6 and two right expansion bracket 7 of expansion bracket.Clamping screw 14 is unclamped, adjustment expansion plate 3 inserts the length of bottom plate 1, while can adjust
Left expansion bracket 6 inserts the length of left support frame 4 and right expansion bracket 7 inserts the length of right support frame 5, then tightens clamping screw 14
, this can is adapted to the page of different length, and it doesn't matter for width, so as to be adapted to different size of books, is adjusting
When, relatively can intuitively, quickly it be adjusted in place by graduation mark 15.
