[0034] As Figure 3As shown in the figure, the utility model makes the connection between the four sides of the paving brick body 1 and other paving brick bodies 1 more firm, tight and not easy to loosen through the lock head mechanism 3 and the lock groove mechanism 4.

[0035] Preferably, as Figure 4 shown, the lock groove mechanism 4 includes a square cavity 6 arranged in the paving brick body 1 and two symmetrically arranged pressing components 7;

[0036] The bottom surface of the square cavity 6 is integrally connected with the paving brick body 1, and a lock groove opening 8 is formed on the upper surface of the square cavity 6, that is, the surface away from the paving brick body 1;

[0037] The pressing component 7 includes a sliding block 9 and a return spring 10; the return spring 10 is arranged horizontally, one end is fixed on the side wall of the square cavity 6, and the other end is connected to the sliding block 9;

[0038] When the return spring 10 is in a natural state, a locking cavity 11 is formed between the two sliding blocks 9, and the opening size of the locking cavity 11 is smaller than the opening size of the lock groove opening 8.

[0039] Preferably, the sliding block 9 is a columnar structure arranged horizontally. The cross-section of the sliding block 9 near the lock groove opening 8 is a right-angled trapezoid, and the shorter upper base of the right-angled trapezoid is close to the lock groove opening 8; the cross-section of the sliding block 9 near the bottom surface of the square cavity 6 is a square, which is integrally connected to the lower base of the right-angled trapezoid, and the side length of the square is smaller than the base length of the right-angled trapezoid;

[0040] When the return spring 10 is in a natural state, the two sliding blocks 9 are abutted against each other, the top surface of the sliding block 9 does not expose the lock groove opening 8, and the ends of the two sliding blocks 9 near the bottom surface of the square cavity 6 form a locking cavity 11.

[0041] Preferably, as Figure 4-5 shown, a pulley 14 is arranged at the bottom of the sliding block 9 to facilitate the movement of the sliding block 9.

[0042] Preferably, as Figure 2 、 Figure 4 shown, the lock head mechanism 3 includes a connecting block 12 and an inserting block 13; the connecting block 12 is arranged horizontally, one end is fixed on the paving brick body 1, and the other end is fixedly connected to the inserting block 13;

[0043] The longitudinal cross-sectional dimension of the connecting block 12 is smaller than the longitudinal cross-sectional dimension of the inserting block 13;
