Tool for catching lower part of rail

The present invention relates to a tool used for shifting a rail. A tool for catching a lower part of a rail, according to an embodiment of the present invention, comprises: a rail support part inserted into a part of the rail; a bar coupling part disposed on a straight line together with the rail support part and having a bar coupling hole formed therein so as to be opposite to the rail support part; a folding hinge part that connects the bar coupling part and the rail support part and rotates only in the opposite direction to that in which the bar coupling part is lifted up while rail shifting such that the rail support part is folded from the bar coupling part; a return spring provided on the bar coupling part to support the rail support part by means of a resilient force such that the rail support part returns to the first position in the state in which the rail support part is folded from the bar coupling part; and a bar-shaped handle bar coupled to the bar coupling hole to apply a force. Accordingly, it is possible to prevent safety accidents caused by the tool while rail shifting.
