To keep the lock mechanism 9 in the locked state, the rotary block 906 is rotated clockwise in the direction shown in fig. 7 until the lower surface of the rotary block 906 abuts against the upper surface of the rail body 3. At this time, the rotation axis of the lock lever 905, the rotation block 906, and the center of the engagement portion between the lock lever 905 and the lock table 907 are almost aligned to form a "mechanical dead point", and the lock mechanism 9 is in a locked state. Finally, the nut 909 is screwed clockwise to be tightly attached to the inner wall of the movable block 904, so that the further anti-loosening effect is achieved on the jacking of the bolt 901. When dismantling the guide rail body 3, only need carry on above-mentioned opposite operation can: firstly, the rotating block 906 rotates anticlockwise, and after the rotating block leaves the surface of the guide rail body 3, the locking mechanism 9 is released from a mechanical dead point state; then, the nut 909 and the bolt 901 are rotated counterclockwise, so that the movable block 904 moves in the opposite direction to the first fixed block 903 until the locking bar 905 and the locking table 907 are separated, and the locking bar 905 is rotated clockwise, so that the locking bar 905 and the locking table 907 are completely separated. Any connection relation between the guide rail bodies 3 at the two ends does not exist any more, and the two guide rail bodies 3 are disassembled and separated.
The above is only the embodiment of the present invention, and is not the limitation of the protection scope of the present invention, all the equivalent structure changes made in the contents of the specification and the drawings, or the direct or indirect application in other related technical fields are included in the patent protection scope of the present invention.
