The positioning block 4 is provided with a stop end 42, and the support block 2 is provided with a stop edge 27 that can block the stop end 42 when the support protrusion 41 is stuck on the support part 3, thereby preventing the support protrusion 41 from moving upward. The stop edge 27 prevents the support protrusion 41 from rotating upward.

[0038] The support block 2 is provided with sliding grooves 28 into which the mounting piece 1 is inserted at both ends. The sliding grooves 28 extend vertically and are C-shaped with the opening facing the back. After the mounting piece 1 is inserted into the sliding groove 28, the support block 2 cannot move back and forth. The support block 2 is also provided with a balancing protrusion 29 that can abut against the end face of the mounting piece 1 when the mounting piece 1 is inserted into the sliding groove 28. The balancing protrusion 29 keeps the support block 2 balanced and reduces the front and rear gap between the support block 2 and the mounting piece 1.

[0040] Example 3, as Figure 8 As shown, the difference from Embodiment 1 is that the shapes of the support block 2 and the positioning block 4 are slightly different, and the installation position of the locking member 7 is different. In this embodiment, one end of the locking member 7 is hinged to the positioning block 4, and the other end is fastened to the bottom edge of the support block 2. The elastic member 6 is a torsion spring.

[0041] Example 4, as Figure 9 As shown, the difference from Embodiment 1 is that the shapes of the support block 2 and the positioning block 4 are slightly different, and the elastic element 6 is integrally formed on the upper end of the positioning block 4.

[0042] Example 5, such as Figures 10-12 As shown, the difference from Embodiment 1 is that the support block 2 has an elastic wall 24 on one side of the support groove 21, and the positioning block 4 is integrally formed on the elastic wall 24. The positioning block 4 protrudes from the back of the elastic wall 24, and the end of the first latch 25 is rotatably inserted into the elastic wall 24. The two insertion ends 260 are arranged opposite to each other and are inserted into the left and right side walls of the elastic wall 24. In this way, turning the elastic wall 24 can drive the first latch 25 to unlock the first latch 25 from the second latch 26, which is convenient to use.

[0043] Example 6, as Figure 13 As shown, the difference from Embodiment 5 is that the second latch 26 is rotatably inserted into the support block 2, and the two insertion ends 260 extend outward.
