The third direction is the up-down direction in fig. 1, that is, the adjusting plate 16 adjusts the position along the third direction, so that the height of the maintenance guide rail 13 can be adjusted, and the height of the maintenance guide rail 13 is the same as the height of the rail in the conveyor line.

In some embodiments, the maintenance tool further includes a first locking member, the adjusting plate 16 defines a first adjusting hole 161 extending lengthwise along the third direction, one end of the first locking member passes through the first adjusting hole 161 and is screwed to the connecting block 12, so that the adjusting plate 16 can move back and forth along the third direction, and the other end of the first locking member can abut against a side of the adjusting plate 16 departing from the connecting block 12, so as to fix the adjusting plate 16 to the connecting block 12.

In this way, the first locking member is loosened to separate the other end from the adjusting plate 16, the adjusting plate 16 is moved to a predetermined position in the third direction such that the height of the maintenance guide rail 13 is the same as the height of the rail in the conveyor line, and then the first locking member is tightened to abut the other end against the adjusting plate 16, so that the adjusting plate 16 is locked to the connecting block 12 by the first locking member.
