[0024] The bottom template is rectangular. The bottom template 1 has two opposite adjacent ends. One adjacent end is formed with a plug connector 11. The other adjacent end is formed with a socket slot 10. The plug connector 11 is detachably inserted into the socket slot 10 on the bottom template 1 of the adjacent unit plate a.

[0025] The two opposite groove walls of the socket 10 are provided with locking holes. The plug connector 11 is provided with a through hole aligned with the locking hole. Lock rods 12 are elastically installed at both ends of the through hole. One end of the lock rod 12 extends into the lock hole. An unlocking structure 15 is installed in the through hole. The unlocking structure 15 is used to drive the two lock rods 12 to move toward each other so that the lock rods 12 return to the through hole.

[0026] In this embodiment, see Figure 4 As shown, one end of the lock rod 12 is connected to a lock tongue 13. An end of the lock tongue 13 away from the lock rod 12 is formed with an oblique end surface 130. When the plug connector 11 is inserted into the socket 10, the corner of the notch of the socket 10 presses against the oblique end surface 130 to make the lock tongue 13 retreat into the through hole. After the through hole is aligned with the lock hole, the lock tongue 13 extends into the lock hole.
