Abstract

The utility model discloses a scriber for staff blackboard-writing, which is formed by a handle (1), a blackboard eraser (2) and chalks (3). The scriber is characterized in that five chalk insertion holes (5) are equidistantly arranged on the left side of the handle (1), the chalks (3) are arranged inside the chalk insertion holes (5) and positioned by chalk positioning devices (4), and the blackboard eraser (2) is fixed on the right side of the handle (1). The scriber for staff blackboard-writing with convenient use and easy operation leads staff drawing to be more highly efficient and accurate with high parallelism among lines, and has the advantages of being capable of completing drawing at one time, saving time and labor, lowering work intensity and improving teaching efficiency and teaching quality of teachers.

Description

Staff writing on the blackboard scriber

Technical field

The utility model relates to a kind of music teaching apparatus, a kind of specifically staff writing on the blackboard scriber.

Background technology

In present music classroom instruction, generally be the teacher by ruler with chalk five parallel lines that on blackboard, draw one by one, and then write spectrum in the above, impart knowledge to students.The weak point of this line drawing method is: owing to need setting-out one by one, cause being difficult to keeping parallelism between line and the line, complex operation has reduced operating efficiency simultaneously, has strengthened working strength, has influenced quality of instruction.

Summary of the invention

The purpose of this utility model is to provide a kind of use simple in structure, easy to use, easy, the drafting that makes staff more efficiently, the scriber of staff writing on the blackboard accurately.

In order to reach above purpose, the technical scheme that the utility model adopted is: this staff writing on the blackboard scriber, constitute by handle, blackboard eraser and chalk, it is characterized in that: equidistantly in the left side of handle be provided with five chalk patchholes, chalk is located in the chalk patchhole, and fix with the chalk positioner, on the right side of handle fixing on blackboard eraser.

The utility model is also implemented by following measure: described chalk positioner, constitute by arc pressuring plate, screw rod, turning handle and catch, arc pressuring plate is located in the mouth edge of chalk patchhole, in the circular groove of arc pressuring plate seat end, be provided with circular catch, the fixing screw rod of going up in the center of catch, screw rod are connected and fixed with turning handle after passing screw on the handle.

The beneficial effects of the utility model are: compare with the method for drawing staff at present on blackboard, easy to use, easy operation, make the drafting of staff efficient more, accurate, depth of parallelism height between line and the line, once can be drawn as, time saving and energy saving, reduced working strength, improved teacher's efficiency of teaching and quality of instruction.

Fig. 3 analyses and observe enlarged diagram for the structure of chalk positioner of the present utility model.

The specific embodiment

Make the utility model with reference to accompanying drawing 1,2,3.This staff writing on the blackboard scriber, constitute by handle 1, blackboard eraser 2 and chalk 3, it is characterized in that: equidistantly in the left side of handle 1 be provided with five chalk patchholes 5, chalk 3 is located in the chalk patchhole 5, and fixing with chalk positioner 4, thereby makes five chalks 3 setting-out simultaneously, and be parallel to each other, on the right side of handle 1 fixing on blackboard eraser 2 so that stagger the time and can in time wipe writing, improved the render speed and the quality of staff.

Described chalk positioner 4, constitute by arc pressuring plate 6, screw rod 7, turning handle 8 and catch 9, arc pressuring plate 6 is located in the mouth edge of chalk patchhole 5, in the circular groove of 6 ends of arc pressuring plate, be provided with circular catch 9, the fixing screw rod 7 of going up in the center of catch 9, screw rod 7 are connected and fixed with turning handle 8 after passing screw on the handle 1.

When using the utility model, earlier five chalks 3 are respectively charged in the chalk patchhole 5, adjust the length of every chalk 3, make the outer end alignment of chalk 3, rotate turning handle 8 again, arc pressuring plate 6 is pressed on chalk 3 in the chalk patchhole 5, can setting-out on blackboard, can once be drawn as like this, time saving and energy saving, improved efficiency of teaching.

Claims
