Solution of the present utility model is: by upper and lower fixed strip the scale ruler is housed on the support of band guide rail, the sliding axle that the side that can slide on guide rail has aperture is housed on the support between the upper and lower fixed strip, on the guide rail of the support above the following fixed strip, the pen clip bar is housed also, have deep-slotted chip breaker on it, on the following fixed strip also correspondence have deep-slotted chip breaker, the other end that two one ends can be plugged on the grafting bar of upper and lower fixed strip and sliding axle one end has connecting hole.Like this, utilize two the grafting bars and the grafting of upper and lower fixed strip and the sliding axle teaching chi that becomes various uses capable of being combined, mix pen and draw point annex and can constitute compasses.
The sliding type multifunctional teaching chi that the utility model provides is the combination that utilizes each member, dismounting becomes the teaching chi of multiple indispensability and the educational aid of other purposes flexibly, it integrates the anteflexion special ruler of standing body, ruler, square, T-square, slide measure and garden and advises, the many usefulness of one chi greatly facilitate teacher's teaching.Help carrying out of activities such as each course teaching of middle and primary schools.In this teaching chi when combination, do not need by any instrument, and walking just dismounting flexibly becomes multi-purpose teaching chi and sports equipment on foot, have reasonable in design, modern design, volume is little, and is in light weight, multiple functional, the scope of application is wide, and is simple in structure, characteristics easy to use.
Referring to accompanying drawing, detailed content of the present utility model further describes as follows:
At first accompanying drawing is described:
Fig. 1 represents structural representation of the present utility model.;
Fig. 2 represents the structure chart of support;
The side view of Fig. 3 presentation graphs 1.
Fig. 4,5,6,7,8,9 represents to be assembled into the schematic diagram of the anteflexion special ruler of standing body, slide measure, square, T-square, ruler and garden rule respectively.
Referring to Fig. 1, Fig. 2, Fig. 3, sliding type multifunctional teaching chi of the present utility model, it is characterized in that going up by last at the support (1) of band guide rail (10), following fixed strip (3), (5) scale ruler (2) is housed, last, be equipped with on the support (1) between the following fixed strip (3) (5) and can go up the sliding axle (4) that the side of sliding has aperture (11) at guide rail (10), sliding axle (4) is gone up at guide rail (10) and is slided, can go up indicating graduation at ruler (2), on the guide rail (10) of the support (1) above the following fixed strip (5), pen clip bar (6) is housed also, have deep-slotted chip breaker (7) on it, on the following fixed strip (5) also correspondence have deep-slotted chip breaker (7), in the deep-slotted chip breaker of pen clip bar (6) and following fixed strip (5), can adorn pencil, various pens such as chalk, the draw point of can packing in the aperture (11) of sliding axle (4) side promptly constitutes compasses.The other end that two 1 ends can be plugged on the grafting bar (8) of upper and lower fixed strip (3), (5) and sliding axle (4) one ends has connecting hole (13), two grafting bars (8) can be linked together by draw point, two grafting bars (8) are plugged on different positions respectively or with being plugged on different positions again after two grafting bars (8) connection, just are combined into multi-purpose teaching chi.Referring to accompanying drawing, two grafting bars (8) are inserted in the two ends of sliding axle (4) respectively, it is the anteflexion dip stick of constituting body, as shown in Figure 4, during use, dip stick is fixed on the Gao Tai appropriate location, the two knees of experimenter can not be crooked, and the leg posture that keeps attentioning is done the trunk bending forwards campaign, and two fingers are aimed at the grafting bar (8) on the dip stick down simultaneously, when finger produces pressure to grafting bar (8), sliding axle (4) just can drive grafting bar (8) and move down, and when test finishes, grafting bar (8) just is parked on certain scale of ruler (2) together with sliding axle (4), the teacher just obtains accurate data, in measuring process, the teacher only notes that student's both legs can not crooked get final product, because of examination person's both hands sliding axle (4) that refers to exert oneself simultaneously could move, not only easy to use, and measure accurately.Two grafting bars (8) are inserted in the same end of fixed strip (3) and sliding axle (4) respectively, as shown in Figure 5, promptly constitute slide measure, mobile sliding axle (4) is convenient to carry out cassette and is measured.With two grafting bars (8) by connecting hole (13) by an end that is inserted into fixed strip (8) after the draw point butt joint again, and mobile sliding axle (4) puts in place downwards, it is the form right angle chi, as shown in Figure 6, on the basis of Fig. 6, two grafting bars (8) are inserted in the two ends of fixed strip (3) respectively, promptly constitute T-square, as shown in Figure 7, remove two grafting bars (8), be a common ruler, as shown in Figure 8, in the gaging hole (11) of sliding axle (4), insert draw point (15), pen (16) is housed between pen clip bar (6) and the following fixed strip (5), and promptly advise in the formation garden, as shown in Figure 9, mobile sliding axle (4), the circle that varies in size that can draw comes.
