A first fastening hole 8 is provided on the fixing piece 23, and a second fastening hole 81 is provided on the sliding piece 3. When the first fastening hole 8 and the second fastening hole 81 are aligned, an external screw can be screwed into the first fastening hole 8 and the second fastening hole 81 to connect and fix the positioning piece 2 and the sliding piece 3, so as to ensure that when the positioning hole 5 passes through the expansion bolt, the entire box body 1 will not shift due to the displacement of the sliding piece 3.

[0033] Based on the above embodiment: The abutting end 31 is provided with an abutting arc surface 9 that can abut against the positioning piece 2.

[0034] The above specific improvement is as follows: As Figure 5 shown in the figure, an abutting arc surface 9 is provided at the abutting end 31 of the sliding piece 3. Through the setting of the abutting arc surface 9, the frictional contact force between the positioning piece 2 and the sliding piece 3 can be effectively increased, and the connection strength between the two can be improved.

[0035] Obviously, the above embodiments are only examples given for clear illustration, and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description.
