In the use process, the smearing requirement of the standard answer sheet checks can be met without special cutting and grinding, so that the smearing device is convenient to use in the standard examination process, has a good smearing effect, is beneficial to improving the answer efficiency, and is suitable for replacing the traditional product to be used in a large range.

Description

The standardization examination pencil special

The utility model relates to a kind of examination articles for use, and particularly a kind of standardization examination is coated with the pencil of answering card special use.

Growing along with the quickening of examination system reform step and computer information technology, existing all kinds of examinations at present adopt standard mode to carry out more, in the i.e. examination process paper and answering card are separated, the examinee makes the corresponding selection back corresponding answer choice of pencil mark on answering card.The existing standardization examination serial pencils of traditional HB that adopt more, its lead for retractable pencil cross section is rounded, needs during use cut and grind to form the square of definite shape with cutter, even like this, " once smear " and also be difficult to the requirement that reaches desirable, often need repeatedly to replenish to smear, greatly reduce efficiency.

The purpose of this utility model provides and a kind ofly can effectively overcome the problems referred to above take place, scientific structure, novel standardization examination pencil special easy to use.

The purpose of this utility model is achieved in that it comprises pencil body and lead for retractable pencil, is characterized in that: the cross section of lead for retractable pencil is a square structure.

Above-mentioned pencil body can be traditional wooden structures, also can be for being loaded with the structure of starting writing certainly of a plurality of lead for retractable pencils;

The utility model is because the cross section of its lead for retractable pencil is a square structure, therefore need not the special system of cutting in its use and grind the requirement of smearing that promptly can satisfy the standardization answering card grid, so it is easy to use in the standardization examination process, and scribble effect is good, once smear and to reach requirement, help improving efficiency, suitable replace traditional product and used on a large scale.

Below in conjunction with accompanying drawing in detail the utility model is described in detail.

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

Fig. 2 is the structural representation of another embodiment of the utility model.

Fig. 3 is user mode figure of the present utility model.

The utility model comprises pencil body 1 and lead for retractable pencil 2, with the existing product difference be that the cross section of lead for retractable pencil 2 is a square structure.Pencil body 1 of the present utility model can be traditional wooden structures as shown in Figure 1, also can adopt the structure of starting writing certainly as shown in Figure 2, and above-mentioned two kinds of structures are prior art, no longer describes in detail herein; The shape of its lead for retractable pencil 2 cross sections can be rectangle, also can be square, and its four jiaos can be the right angle, also can be for having the fillet of circular arc.

When using the utility model, as shown in Figure 3, the cross-sectional direction of adjusting lead for retractable pencil 2 is so that the grid on itself and the standardization examination answering card 3 matches, next can smear as using traditional pencil to finish, difference is because the cross section of lead for retractable pencil 2 adopts square structure, and it is smeared width and is equal to grid width on the answering card 3, and therefore a scribble effect is good.
