When the first plug board 4 moves downward, the lower bevel will squeeze the bevel of the second plug board 5, and the second plug board 5 can be pushed to one side, that is, it can be smoothly inserted into the first groove;

[0037] A second groove is formed in the middle of the lower surface of the floor base layer 1. A cover plate 3 is abutted against the side of the floor base layer 1 away from the finishing main body 2. Third grooves are formed on both sides of the lower surface of the cover plate 3. Opening the cover plate 3 can maintain, repair and replace the components in the first groove and the second groove.

[0038] Embodiment 2

[0039] Referring to Figures 1 - 5, a transmission mechanism for driving the movement of the two second plug plates 5 is provided on the inner side of the second groove. The transmission mechanism includes an iron sheet 8 and a pulling rope 9. The iron sheet 8 is slidably arranged inside the second groove. Stopper blocks 10 are fixedly arranged on both inner walls on the two sides of the middle of the second groove. The lower side of the iron sheet 8 abuts against the upper side of the stopper block 10. A through hole is provided between the first groove and the second groove. One side of the second plug plate 5 close to the through hole is fixedly provided with a cross bar 6. One end of the cross bar 6 extends to the inner side of the through hole.

Both sides of the sliding block 15 abut against the inner wall of the sliding groove, so that the sliding block 15 cannot rotate, that is, it can stably slide.

[0042] In the present utility model, during use, a magnet is placed in the middle of the upper surface of the decorative surface body 2. The magnet magnetically adsorbs the iron sheet 8, causing the iron sheet 8 to move upward, which in turn causes the iron sheet 8 to pull the two pull ropes 9. The pull ropes 9 pull the corresponding cross bars 6, causing the second plug board 16 to leave the first plug board 4, thereby releasing the limitation on the decorative surface body 2. Then, quickly pull the decorative surface body 2 upward, and the first plug board 4 can be pulled out of the first groove, realizing the quick disassembly of the decorative surface body 2, which is convenient for separately replacing the decorative surface body 2. After the entire floor is removed, pull the slider 15, causing the second plug rod 16 to leave the jack, thereby releasing the limitation on the first plug rod 13, enabling the cover plate 3 to be separated from the floor base layer 1, exposing one side of the first groove and the second groove, and facilitating the repair and replacement of the components in the first groove and the second groove.

[0043] Only some exemplary embodiments of the present utility model have been described by way of illustration. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present utility model. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
