The assembling protrusion 12 is a convex column which is arranged on the side wall 10a of the eraser body 1 and extends outwards. The assembling protrusion 12 can be inserted into the assembling groove 11 from the notch of the assembling groove 11. In the technical scheme, another arrangement scheme and an assembly mode of the assembly groove 11 and the assembly protrusion 12 are defined, in the scheme, a convex column is inserted into a notch, and the scheme may have the problem that when a third eraser is inserted, two inserted erasers are loosened. But the scheme also has the effect of conveniently adjusting the plugging shape in the plugging process.

The second embodiment is a scheme as shown in fig. 1 and 2, and is also a scheme which is mainly embodied in the scheme, and specifically comprises the following steps: at least one end of the upper end and the lower end of the assembling groove 11 penetrates through the upper end face and the lower end face of the eraser body 1, and the caliber of the inner end of the assembling groove 11 is larger than that of the outer section thereof. The assembling protrusion 12 is matched with the assembling groove 11 in shape, and the assembling protrusion 12 can only be installed in or separated from the assembling groove 11 through the upper port part 111 and/or the lower port part 112 of the assembling groove 11; in the scheme shown in the figure, the upper end and the lower end of the assembling groove 11 both penetrate through the upper end face and the lower end face of the eraser body 1, and the assembling protrusion 12 can be installed in or detached from the assembling groove 11 through the upper end opening part 111 and the lower end opening part 112 of the assembling groove 11. On the basis of the above-mentioned solution that the assembling groove 11 and the assembling protrusion 12 are opened at the side of the eraser body 1, the technical solution defines the way that the assembling protrusion 12 is inserted into the assembling groove 11 through the upper end opening 111 and/or the lower end opening 112 of the assembling groove 11, so that only the longitudinal operation will cause the connection between the adjacent erasers to be loosened. In the process of expanding and inserting in the plane direction, particularly, the connecting structure is placed on a platform (such as a desktop), so that the connecting structure ensures that the adjacent eraser is firmly connected and is not loose.

On the basis of the second embodiment, the section of the assembling groove 11 is a dovetail groove gradually reduced from the inner end to the outer end, and the section of the assembling protrusion 12 is a dovetail protrusion gradually increased from the inner end to the outer end. In the technical scheme, the assembly groove 11 and the assembly protrusion 12 are matched by adopting the dovetail groove and the dovetail protrusion, so that the rapid assembly is facilitated, and the purpose that the side surface direction is not loose is achieved.
