Abstract
The utility model discloses an English scriber. The English scriber comprises a ruler box (1), four chalk holders (2) and a handheld part (3), wherein the handheld part (3) is fixedly connected with the ruler box (1); the ruler box (1) is hollow inside, and upper and lower horizontal shafts (4 and 5) are arranged inside the ruler box (1); the four chalk holders (2) are installed on the horizontal shafts (4 and 5) and slide along the horizontal shafts (4 and 5). With the adoption of the structure, distances between the chalk holders on the ruler box can be adjusted, and three regular grids with four lines can be scribed on a blackboard according to actual teaching needs, so that time and effort are saved.
Description
Technical field
The utility model relates to a kind of teaching auxiliary implement, relates in particular to a kind of scriber for English drawing.
Background technology
In English teaching, need to draw three lattice four lines, conventionally use ruler, not only waste time and energy, also be difficult to draw four regular lines.Even if draw out four regular lines by instrument, distance between centers of tracks is conventionally fixing, cannot adjust as required.
Summary of the invention
The utility model provides a kind of being convenient to regulate, and can as required, draw out the scriber for English drawing of different distance between centers of tracks.
The technical solution of the utility model is: comprise scale box 1, chalk holder 2 and Handheld Division 3, described Handheld Division 3 is fixedly connected with scale box 1, described scale box 1 inner hollow, inside arranges upper and lower two trunnion axis 4,5, described chalk holder 2 is arranged on described trunnion axis 4,5, along described trunnion axis 4,5, slides.
Described chalk holder 2 comprises clamping chamber 6, hollow connecting rod 7, described clamping chamber 6 is fixedly connected with described hollow connecting rod 7, on described hollow connecting rod 7, there are the 4a of hole up and down, the 5a that match with described trunnion axis 4,5, between described clamping chamber 6 and the lower hole 5a of described hollow connecting rod 7, have retractor device 10.
Described retractor device 10 comprises T-shaped top cover 11, be arranged on the spring 12 on T-shaped top cover 11 and be enclosed in the plate washer 13 of spring 12 outsides.
Longitudinally there is dilatation joint 8 in described clamping chamber 6, in the outside of described clamping chamber 6 dilatation joints 8, is provided with device for screwing up 9.
The edge relative with Handheld Division 3 at described scale box 1 outer surface arranges scale 14.
Described Handheld Division 3 grips shape according to palm hand-held groove 15 is set.
Described chalk holder 2 is four.
The utility model adopts chalk holder to slide along trunnion axis, according to scale setpoint distance, by the fixing chalk holder of retractor device, not only can draw out three regular lattice four lines, and according to teaching needs, adjust at any time the distance of chalk holder, draw the straight line of different distance between centers of tracks, convenient operation is time saving and energy saving.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described further.
Fig. 1 is internal structure schematic diagram of the present utility model.
Fig. 2 is front view of the present utility model.
Fig. 3 is the enlarged drawing of chalk holder in the utility model.
In figure: 1, scale box, 2, chalk holder, 3, Handheld Division, 4,5, trunnion axis, 4a, 5a, upper and lower hole, 6, clamping chamber, 7, hollow connecting rod, 8, dilatation joint, 9, device for screwing up, 10, retractor device, 11, T-shaped top cover, 12, spring, 13, plate washer, 14, scale, 15, hand-held groove.
The specific embodiment
As shown in Figure 1, this scriber for English drawing comprises scale box 1, chalk holder 2 and Handheld Division 3, described Handheld Division 3 is fixedly connected with scale box 1, described scale box 1 inner hollow, inside arranges upper and lower two trunnion axis 4,5, described chalk holder 2 is arranged on described trunnion axis 4,5, along described trunnion axis 4,5, slides.Trunnion axis 4,5 is parallel to each other, and setting vertical with chalk holder 2, plays the fixedly effect of chalk holder 2.
As shown in Figure 3, chalk holder 2 comprises clamping chamber 6, hollow connecting rod 7, described clamping chamber 6 is fixedly connected with described hollow connecting rod 7, on described hollow connecting rod 7, there are the 4a of hole up and down, the 5a that match with described trunnion axis 4,5, between described clamping chamber 6 and the lower hole 5a of described hollow connecting rod 7, have retractor device 10.Described retractor device 10 comprises T-shaped top cover 11, be arranged on the spring 12 on T-shaped top cover 11 and be enclosed in the plate washer 13 of spring 12 outsides.During use, chalk is inserted to clamping chamber 6, withstand T-shaped top cover 11, regulate the size of top power by spring 12, by baffle plate 13, withstand the trunnion axis 5 through lower hole 5a, play the fixedly effect of chalk holder 2, this baffle plate 13 is the tubular construction of bottom surface opening.Longitudinally there is dilatation joint 8 in described clamping chamber 6, in the outside of described clamping chamber 6 dilatation joints 8, is provided with device for screwing up 9.By device for screwing up 9, chalk is fixed in clamping chamber 6.
As shown in Figure 2, at the described scale box 1 outer surface edge relative with Handheld Division 3, scale 14 is set.Described Handheld Division 3 grips shape according to palm hand-held groove 15 is set.Described chalk holder 2 is preferably four.
The utility model is not limited to draw three lattice four lines, and quantity and the distance of chalk holder can be set as required flexibly, draws the straight line of different distance between centers of tracks.
