Abstract

The utility model discloses a mark scraper for English letters. The mark scraper comprises a main scale and an auxiliary scale which are hinged with each other, the main scale is longer than the auxiliary scale, each of the main scale and the auxiliary scale is longitudinally provided with a slideway, chalk holders sliding along the slideways are respectively arranged on the slideways, each of the main scale and the auxiliary scale is hinged with an assisting scale, the hinge point of the main scale and the corresponding assisting scale as well as the hinge point of the auxiliary scale and the corresponding assisting scale are located on the same circumference by taking the hinge point of the main scale and the auxiliary scale as the center, and the tail end of each assisting scale is provided with a chalk holder. The chalk holders on the main scale and the auxiliary scale can be adjusted in position by rotating included angles among the main scale, the auxiliary scale and the assisting scales, and three cases with four lines in different spacing can be marked; when not in use, the mark scraper which can be rotated to be folded is convenient to carry and flexible in use.

Description

A kind of scriber for English drawing
Technical field
The utility model relates to a kind of English-teaching aid, relates in particular to a kind of scriber for English drawing.
Background technology
In English teaching, write English word on blackboard, usually need to use ruler to draw three lattice four lines, waste time and energy, and be difficult to draw four regular lines, while drawing three lattice four lines by instrument, existing drawing tool volume is larger, carries inconvenience.
Summary of the invention
It is a kind of easy to carry that the utility model provides, and uses scriber for English drawing flexibly.
The technical solution of the utility model is a kind of scriber for English drawing, comprise main scale and secondary chi, described main scale and described secondary chi are hinged, the length of described main scale is greater than described secondary chi, described main scale and described secondary chi slideway is longitudinally set respectively, the chalk holder sliding along described slideway is set on described slideway, hinged auxiliary scale respectively on described main scale and described secondary chi, the opposite end of the main scale described in the auxiliary scale on described secondary chi is positioned at and described secondary chi pin joint, the pin joint of the pin joint of described main scale and described auxiliary scale and described secondary chi and described auxiliary scale is positioned at take on the same circumference that the pin joint of described main scale and described secondary chi is the center of circle, the end of described auxiliary scale arranges chalk holder, clamper cavity is set in described auxiliary scale, chalk holder on described auxiliary scale can rotate in clamper cavity.
The length of described auxiliary scale equal described secondary chi length half.
The pin joint of the pin joint of the pin joint of described main scale and described secondary chi, described main scale and described auxiliary scale, described secondary chi and described auxiliary scale arranges respectively device for screwing up.
Described main scale, described secondary chi and described auxiliary scale can rotate coincidence.
The beneficial effects of the utility model are by the angle between rotation main scale, secondary chi and auxiliary scale, regulate the position of chalk holder on main scale, secondary chi, can mark three lattice four lines of different distance between centers of tracks, and when not using, can realize rotating and overlap, reduce taking up room of teaching aid, easy to carry, use flexibly.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is top view of the present utility model.
In figure 1, main scale, 2, secondary chi, 3,4, auxiliary scale, 5, device for screwing up, 6, slideway, 7, chalk holder, 8, clamper cavity, 9, slide rail, 10, scale.
The specific embodiment
As Fig. 1, shown in Fig. 2, the technical solution of the utility model comprises main scale 1 and secondary chi 2, main scale 1 and secondary chi 2 are hinged, the length of main scale 1 is greater than the length of secondary chi 2, main scale 1 and secondary chi 2 slideway 6 is longitudinally set respectively, chalk holder 7 is set on slideway 6, chalk holder 7 can slide along slideway 6, hinged auxiliary scale 3 on main scale 1, hinged auxiliary scale 4 on secondary chi 2, wherein the auxiliary scale 4 on secondary chi 2 is positioned at main scale 1 and the relative end of secondary chi 2 pin joints, the pin joint of the pin joint of main scale 1 and auxiliary scale 3 and secondary chi 2 and auxiliary scale 4 is positioned at take on the same circumference that the pin joint of main scale 1 and secondary chi 2 is the center of circle, the end of auxiliary scale 3 and auxiliary scale 4 arranges respectively chalk holder 7, the interior clamper cavity 8 that arranges respectively of auxiliary scale 3 and auxiliary scale 4, chalk holder 7 on auxiliary scale 3 and auxiliary scale 4 can rotate in clamper cavity 8.
The length that is less than secondary chi 2 of the length of auxiliary scale 3,4, the length that is preferably auxiliary scale 3,4 equals half of secondary chi 2 length.
At main scale 1, slide rail 9 is set on longitudinally, this slide rail 9 is positioned on the opposite face of chalk holder 7 on main scale 1, and the scale 10 that can slide is set on slide rail 9, and scale 10 can horizontally rotate by 360 degree on main scale 1, scale 10 be can be flexible scale.Scale is mainly used in measuring distance and the level at adjacent chalk holder interval.
At main scale 1 and pin joint, the main scale 1 of secondary chi 2, with the pin joint place of auxiliary scale 4, device for screwing up 5 is set respectively with the pin joint of auxiliary scale 3, secondary chi 2.Device for screwing up 5 is for being fixed main scale 1 and secondary chi 2, main scale 1 and auxiliary scale 3, secondary chi 2 and 4 angles that regulate of auxiliary scale.
Main scale 1, secondary chi 2 and auxiliary scale 3,4 can rotate coincidence.As shown in Figure 1, be preferably: the auxiliary scale 4 on secondary chi 2 be positioned at secondary chi 2 below, secondary chi 2 be positioned at main scale 1 below, the auxiliary scale 3 on main scale 1 be positioned at main scale 1 above.When this teaching aid does not use, chalk holder on main scale 17 is slided into the top of main scale 1, the position that surpasses auxiliary scale 3, chalk holder 7 on secondary chi 2 slides into the bottom of secondary chi 2, the chalk holder 7 of auxiliary scale 3 on main scale 1 is rotated in clamper cavity 8, rotate each chi, can realize rotating overlapping.
Should be understood that, the above-mentioned specific embodiment of the present utility model is only for exemplary illustration or explain principle of the present utility model, and do not form restriction of the present utility model, the utility model is not limited only to draw three lattice four lines, can as multipurpose drawing tool, use flexibly as required.Therefore any modification of, making, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model in the situation that not departing from spirit and scope of the present utility model.In addition, the utility model claims are intended to contain whole variations and the modification in the equivalents that falls into claims scope and border or this scope and border.
