It can be understood that the bearing plate 2 is overlapped on the first sliding member 31, so the first sliding member 31 can move relative to the bearing plate 2. Specifically, after the structure to be assembled and disassembled is placed on the supporting plate 2, the first sliding member 31 is slid along the first direction, and the first sliding member 31 drives the first clamping member 32 and the locking member to move synchronously along the first direction, so that the clamping portion 322 can be distributed above the structure to be assembled and disassembled; then the first connecting portion 321 is moved along the second direction, driving the first clamping member 32 and the locking member to move synchronously along the second direction until the clamping portion 322 overlaps the structure to be assembled and disassembled; then the relative positions of the first clamping member 32, the structure to be assembled and disassembled and the supporting plate 2 are locked by the locking member, so that the clamping portion 322 is pressed against the structure to be assembled and disassembled, so as to fix the structure to be assembled and disassembled in the setting position on the supporting plate 2.
