The change of the pressing platform 81 pulls the connecting bar 84 to change. The connecting bar 84 pulls the variable seat 85 to change. During the change of the variable seat 85, it pulls the embedding rod 89 to change. The embedding rod 89 moves into the embedding interface C810, allowing the trapezoidal platform A72 and the connecting platform B74 to be tightened again, and then the connecting end A51 and the connecting end B52 are tightened again, so that the connecting end A51 and the connecting end B52 cannot be disassembled, so as to ensure the secure fastening between wall panel A1 and wall panel B2.
