When the first slot 41 moves to the position of the first locking block 33, since the first locking block 33 is triangular in shape and the inclined surface is at the top, the inclined surface of the first locking block 33 is squeezed by the first slot 41 and slides into the first slide groove 32. When the first fixing block 31 is fully inserted into the first slot 41, the first locking block 33 loses resistance and slides from the first slide groove 32 under the elastic action of the first spring. The first locking block 33 is disengaged from the second groove 43 by rotating the lever 76 18 and the second locking block 33 is disengaged from the second groove 43 . The lever 76 is rotated one hundred and eighty degrees, with the inclined surface of the locking block 75 facing downward, and the connecting rod 4 is moved upward, so that the first groove 41 is disengaged from the first fixing block 31 . The disassembly is completed simply and conveniently.
