By the device that writes that the utility model designs, can make full use of the chalk head of using, greatly reduce because of the discarded waste problem of bringing of chalk head, and simple in structure, easy to operate.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1, a body 2, hanging handle 3, push rod 4, spring
5, block 6, groove 7, gap
The specific embodiment
Further set forth design feature of the present utility model below in conjunction with accompanying drawing and specific embodiment.
A kind of device that utilizes the chalk head to write as shown in Figure 1 comprises the body 1 that can accommodate chalk, lower open mouth on described the body 1; Body 1 upper shed is provided with the hanging handle 2 of a bending, and an end of hanging handle 2 is bent in the body 1, and an end is outside a body 1; Hanging handle 2 flexibly connects by rotating shaft and the support that is arranged on a body 1 upper outside; Hanging handle 2 and support form leverage; An end clamping one upper end of hanging handle 2 in a body 1 has the push rod 3 of groove 6, and the lower end of push rod 3 is provided with block 5 mechanisms and contacts with the chalk head; Between hanging handle 2 and block 5, be provided with one and recover spring 4; Described body 1 lower end is provided with two symmetrical gap 7 near opening part, is equipped with retention mechanism on gap 7.
Described body 1 can be set to two parts up and down, by being threaded.With the convenient chalk of going up.
During use, hanging handle 2 is pressed, because leverage, the part perk that body is 1 li, again push rod 3 and spring 4 are taken out, the chalk head is put into, then push rod 3 and spring 4 are put into, then hanging handle 2 is lifted, compress push rod 3, extrude from the lower end nib, twine several circles with rubber rope again until the chalk head, because rubber rope makes the chalk head no longer bounce back the compacting of chalk head.Utilize the first cover of chalk to reach.
During use, a body 1 is divided into two parts up and down, the chalk head is put into, screw on then, again hanging handle 2 is lifted, compress push rod 3, extrude from the lower end nib until the chalk head, twine several circles with rubber rope again, because rubber rope makes the chalk head no longer bounce back the compacting of chalk head.Utilize the first cover of chalk to reach.
