[0032] In the embodiment, a plurality of positioning columns 11 are uniformly and fixedly arranged on the bottom of the upper box 3, a plurality of positioning connecting holes 19 matched with the positioning columns 11 are formed on the lower upper cover 1, the positions of the positioning connecting holes 19 correspond to the positions of the positioning columns 11, and the positioning columns 11 are clamped into the positioning connecting holes 19 when the upper and lower boxes 3 are stacked, so that the positioning columns 11 can be accurately clamped into the positioning connecting holes 19 formed on the lower upper cover 1 when the upper and lower boxes 3 are stacked, and the design ensures accurate alignment of the upper and lower boxes 3 when stacked, prevents relative sliding or misalignment between the boxes 3, and enhances the overall structural stability of the device.
