[0025] Through the above structure, when multiple groups of isolation frames 1 are connected, the plug block 2 is inserted into the corresponding cavity 6. When the plug block 2 enters the cavity 6, the limit block 5 is squeezed and enters the installation groove 3 to compress the spring 4. When the limit block 5 moves to the slot 7, the limit block 5 is inserted into the slot 7 through the rebound force of the spring 4, and the two connected groups of isolation frames 1 are positioned so that the multiple groups of sockets 1 8 are aligned with the sockets 2 9, and the connecting rod 10 is inserted into the multiple groups of sockets 1 8 and the sockets 2 9 to connect the two groups of isolation frames 1;

[0026] The multiple connected isolation frames 1 are placed between the two support frames 11, the multiple positioning blocks 12 are aligned with the positioning blocks 2 14, the positioning rods 16 pass through the multiple plug holes 3 13 and the plug holes 4 15, and the isolation frames 1 are installed between the two support frames 11.
