Abstract
The utility model provides a teacher's pointer usable for drawing four lines for English and belongs to the technical field of teacher's pointers. One end of a pointer rod is connected with a handle via screw threads while the other end of the pointer rod is connected with a ball cap via screw threads. The pointer rod in the ball cap is provided with a ball nest, and a ball is arranged between the ball nest on the pointer rod and the ball cap. The handle is provided with four uniformly-distributed via holes used for insertion of a chalk. When the teacher's pointer is used and if a blackboard is provided with a chalk groove, the end with the ball is made to face down and the ball is made to roll in the chalk groove; the pointer rod is held by one hand while the chalk is held by the other hand and inserted into one via hole; the pointer rod and the handle are kept upright by the two hands; and one line can be drawn through one via hole each time and thus four lines can be drawn after four times of drawing through the via holes of different heights. If the blackboard is not provided with the chalk groove, a teacher's desk can be placed under the blackboard and used for assisting the line drawing. According to the utility model, the teacher's pointer integrates the function of drawing the four lines for English. When the teacher's pointer is not used, the pointer rod can be screwed off from the handle, thereby reducing the space occupation.
Description
Technical field
The utility model relates to a kind of teacher's pointer that can be used for English four line line, belongs to teacher's pointer technical field.
Background technology
The effect of teacher's pointer in teaching is important, and the effect of teacher's pointer is mainly the sight line in order to guiding student, and teacher's different elevation arms in teaching can be given directions word or formula or the pattern on blackboard, can alleviate teacher's burden.In English teaching, often need to mark four line lattice, and existing four line scriber common configuration complexity and function singlenesses are not easy in school universal.
Summary of the invention
The purpose of this utility model is the problem existing in order to solve above-mentioned prior art, and teacher's pointer can not be used for marking four line lattice, and four line scribers can not be worked as again teacher's pointer and be used.And then provide a kind of teacher's pointer that can be used for English four lines line.
The purpose of this utility model is achieved through the following technical solutions:
A kind of teacher's pointer that can be used for English four line line, comprise: handle, whip bar, ball cap and ball, one end of described whip bar is threaded with handle, the other end of whip bar is connected with ball cap thread, whip bar in ball cap is provided with ball nest, ball is arranged between the ball nest and ball cap on whip bar, handle be provided with four uniform for inserting the through hole of chalk.
When the utility model uses, by the side with ball down, the ball that allows with ledge for chalk on blackboard on blackboard rolls in ledge for chalk on blackboard, one holds whip bar, another holds chalk and allows chalk insert through hole, both hands keep the upright of whip bar and handle, draw a line by the through hole of differing heights at every turn, can mark four line lattice for four times.If there is no ledge for chalk on blackboard on blackboard, lectern can be placed under blackboard, rule by lectern.The function that the utility model has been realized teacher's pointer and English four line line rolls into one.While use, whip bar can be screwed off from handle, reduce taking of space.
Accompanying drawing explanation
Fig. 1 is the one-piece construction schematic diagram that the utility model can be used for the teacher's pointer of English four line line;
Fig. 2 is the partial schematic diagram of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail: the present embodiment is implemented under take technical solutions of the utility model as prerequisite, has provided detailed embodiment, but protection domain of the present utility model is not limited to following embodiment.
As depicted in figs. 1 and 2, a kind of teacher's pointer that can be used for English four line line that the present embodiment is related, comprise: handle 1, whip bar 2, ball cap 3 and ball 4, one end of described whip bar 2 is threaded with handle 1, the other end of whip bar 2 is threaded with ball cap 3, whip bar 2 in ball cap 3 is provided with ball nest 6, and ball 4 is arranged between the ball nest 6 and ball cap 3 on whip bar 2, handle 1 be provided with four uniform for inserting the through hole 5 of chalk.
