[Detailed Description of the Invention] Work Field of Use> This invention relates to a back metal round attachment for school bags, and in particular to a back metal round attachment that allows adjustment of the attachment interval at the upper end of a backpack belt. It is.

<Prior Art> Normally, in a school bag, the distance between the upper ends of the school bag carrying belt is adjusted in accordance with the growth of the child. Conventionally, this type of adjustable back metal round attachment for school bags has been equipped with a back metal round attachment part at the top and an arc-shaped leaf spring at the bottom, as seen in Japanese Utility Model Application Publication No. 63-13018. It is known that a pair of sliders are slidably inserted between the base and the cover of the fixture, and the back metal round is rotatably fitted and attached to the back metal round mounting portion. And in this kind of thing, the position of dorsal mA.

That is, in order to fix the position of the slider, the slider generally has a locking protrusion and the cover has a plurality of engagement recesses.

<Problems to be Solved by the Invention> In the above prior art, the convex part of the slider and the concave part of the cover are engaged by the leaf spring at the bottom of the slider to position the back pocket. To adjust the slider, push down the backrest mounting part of the slider that protrudes from the sliding window of the cover against the leaf spring to push down the entire slider, disengage the protrusion and the recess, and then Positioning is performed by sliding the slider left and right while maintaining the pressed state to engage the engagement recess of the layer.

By the way, in the adjustment operation described above, the slider is pushed down and slid against the biasing force of the leaf spring, so a considerable amount of force is required for the operation, and children may feel pain in their hands and fingers during the operation. The drawback was that it was difficult to operate.

In addition, there is a risk of the skin of your fingers getting caught between the window and the slider during the operation, and since the adjustment is made by engaging the locking protrusion and the engagement recess, the adjustment interval can only be adjusted in stages. There was also the inconvenience of not being able to do so.

Furthermore, there was a problem in that the sliders could only be adjusted one at a time, and the same operation had to be repeated twice for the pair of left and right sliders.

<Means for solving the gap μ point> The present invention addresses the problems such as the poor operability of the back pocket attachment for schoolbags based on the above-mentioned prior art, and provides counterclockwise screws on the left and right in the base and cover. A slide screw with an operation dial formed in the center thereof is rotatably provided, a slider is screwed into each of the reverse threads of the slide screw, and a money holder having a back money holder attachment part is connected to the slider. 2. <Function> In this invention having the above structure, a part of the operation dial of the slide screw protrudes from the operation window of the cover, and the operation dial of the slide screw is partially protruded from the operation window of the cover. The back cover mounting part of the holder protrudes through the sliding window, so when you turn the operation dial with your fingers, the sliders that are screwed into it slide and move in opposite directions, and the integrated back It functions so that the spacing between the gold-receiving attachment parts is adjusted at once.
