Abstract

The utility model discloses a novel blackboard eraser, which comprises an eraser plate, bristles fixed at the bottom of the eraser plate and a handle, and is characterized in that: one end of the eraser plate is conical and the other end of the eraser plate is arc; the upper end face of the eraser plate is provided with two fixing blocks between which a gap is formed; and one end of the handle is hinged to the upper end face of the eraser plate, and the other end of the handle is inserted into the gap between the two fixing blocks. The novel blackboard eraser has the advantages that: (1) the novel blackboard eraser is simple in structure; (2) the novel blackboard eraser easily cleans chalk handwritings at corners of a blackboard; and (3) the novel blackboard eraser is vertically arranged easily.

Description

A kind of novel blackboard eraser

Technical field

The utility model relates to a kind of teaching aid, particularly a kind of blackboard eraser.

Background technology

At present, existing blackboard eraser generally comprises wiping board and is fixed on the hairbrush on the wiping board, and that the two ends of wiping board are is circular-arc, therefore, in cleaning blackboard plate angle, can not the letter written with chalk at plate angle be removed clean, thereby very inconvenience.

Summary of the invention

The problem that the utility model will solve is: a kind of simple in structure, novel blackboard eraser of being convenient to clear up the plate angle and can vertically placing is provided.

In order to solve the problems of the technologies described above, the novel blackboard eraser of the utility model comprises wiping board, is fixed on the hairbrush and the handle of wiping board bottom, and it is characterized in that: an end of said wiping board is the vertebra shape, and an other end is circular-arc.

For the ease of an other end of handle being fixed and handle being used as support bar; The upper surface of said blackboard eraser also is provided with two fixed blocks; Be provided with the gap between the said fixed block; One end of said handle is hinged on the upper surface of blackboard eraser, and an other end is inserted in two gaps between the fixed block.

The beneficial effect that the utility model is obtained is: (1) is simple in structure; (2) end of wiping board is the vertebra shape, and an other end is circular-arc, and taper one end is convenient to stretch in the plate angle, and the letter written with chalk at plate angle is cleaned out; (3) upper surface of blackboard eraser also is provided with two fixed blocks, is provided with the gap between the fixed block, and an end of handle is hinged on the upper surface of blackboard eraser; When wiping erasing blackboard, the other end of handle is inserted in two gaps between the fixed block, handle is fixed; Be convenient to blackboard eraser is held with a firm grip, when needs are vertically placed blackboard eraser, with handle the gap of an other end between fixed block draw back; Use as support bar, the setting that blackboard eraser can be firm on the table.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Fig. 2 is the structural representation of the utility model when vertically placing.

Among the figure: 1, wiping board, 2, handle, 3, hairbrush, 4, fixed block.

The specific embodiment

As shown in Figure 1, the novel blackboard eraser of the utility model comprises wiping board 1, is fixed on the hairbrush 3 and the handle 2 of wiping board 1 bottom, and an end of said wiping board 1 is the vertebra shape, and an other end is circular-arc; The upper surface of said blackboard eraser 1 also is provided with two fixed blocks 4, is provided with the gap between the said fixed block 4, and an end of said handle 2 is hinged on the upper surface of blackboard eraser 1, and an other end is inserted in two gaps between the fixed block 4.

The novel blackboard eraser of the utility model, an end of wiping board 1 is the vertebra shape, and an other end is circular-arc, and taper one end is convenient to stretch in the plate angle, and the letter written with chalk at plate angle is cleaned out;

When wiping erasing blackboard, the other end of handle 2 is inserted in two gaps between the fixed block 4, handle 2 is fixing, be convenient to blackboard eraser is held with a firm grip.

When needs are vertically placed blackboard eraser, as shown in Figure 2, with handle 2 the gap of an other end between fixed block 4 draw back, use as support bar, the setting that blackboard eraser can be firm on the table.

The utility model is not limited to above-mentioned embodiment, and anyone should learn the structural change of under the enlightenment of the utility model, making, every with the utlity model has identical or close technical scheme, all fall within the protection domain of the utility model.
