After this process is completed, the fork arm moves up, and the cantilever beam 17 moves up. At this time, the limiting column 30 is guided by the inclined slot 32 to enter the second straight slot 31.

Then the forklift moves backward to separate the limiting frame from the base 1, and the base 1 is packaged together with the composite brick. After being separated, the forklift places the limiting frame on the ground and resets the cantilever beam 17. The limiting column 30 moves down from the second straight slot 31 to the bottom slot 34, the clamping block connecting rod 18 moves down, and the clamping block 14 resets under the action of the second reset member. When installing a new base 1 and connecting it with the limiting frame, the limiting frame can be inclined backward, and then the base 1 is inserted from the bottom of the front end of the limiting frame, so that the clamping block 14 is clamped into the clamping groove 16.
