The second arc surface on the second slot (b) of the first profile (5), the second profile (6), the third profile (7), and the fourth profile (8) forms a second through hole that can be fitted onto the sleeve (31). The locking rod (2) is located inside the first slot (a). The side wall of the first slot (a) is provided with a locking rod (2) that can enter the side channel (c) between adjacent profiles as the rotating rod (1) rotates. The side channel (c) of the first profile (5) is connected to the side channels (c) of the third profile (7) and the fourth profile (8). The side channel (c) of the second profile (6) is connected to the side channels (c) of the third profile (7) and the fourth profile (8). The side channel (c) is provided with a clearance space for the locking rod (2) to move up and down. The insert (311) is located in the second slot (b). The second slot (b) is provided with a hole through which the bolt can pass and is correspondingly set in the corresponding hole with the screw hole (312). The sleeve (31) is fixed in the second through hole by the insertion of the insert (311) into the second slot (b) and the thread engagement of the bolt after passing through the corresponding hole with the screw hole (312). The locking rod (2) and the insert (311) are provided in fours. The four locking rods (2) and the four inserts (311) are respectively set in the first slot (a) and the second slot (b) of the first profile (5), the second profile (6), the third profile (7) and the fourth profile (8); and are arranged in a cross shape on the sleeve (31). The four locking rods (2) are fixed on the rotating rod (1) and are arranged in a cross shape.

8. A base plate comprising a sheet material (10) and a frame as described in claim 6, characterized in that: The plate (10) is set on the flange (9) of two adjacent profiles. The part of the plate (10) opposite to the side channel (c) is provided with a locking groove (101) into which the locking rod (2) can enter and form a plug-in engagement. The plate (10) is detachably set on the flange (9) through the plug-in engagement of the locking rod (2) and the locking groove (101).

9. A base plate according to claim 8, characterized in that: The locking groove (101) is provided with a locking groove (102) that can cooperate with the locking block (21), and the locking groove (102) is provided with a fitting inclined surface that can fit with the adapting inclined surface (211).
