Embodiment Construction

[0011] The present invention will be specifically described below in conjunction with the accompanying drawings and specific embodiments.

[0012] As shown in FIG. 1, it is a schematic diagram of the specific structure of this embodiment. In the improved chalk box of the present invention, when taking the chalk in the box, the pull-out supporting plate 5 is pulled out, and the rotary block 3 is turned to a horizontal position, and the chalk at the bottom of the box rolls from the transverse seam 4 due to the pressure of the upper chalk After the chalk rolled out reaches the required amount, turn the rotary block 3 to the vertical position to block the chalk in the box so that it will not roll out; when the chalk is not used, turn the rotary block 3 to the vertical position , open the upper box cover 1, put the unused chalk back into the box body 2, cover the box cover, push the pull-out support plate 5 to the bottom of the box, so that the rib 8 just blocks the transverse seam...
