Body portion 110 may have a U-shaped cross-sectional shape surrounding the chain portion 120, in order to support the chain portion 120 more stably.

The chain part 120 moves along the longitudinal direction of the body part 110 and is used to convert the vertical movement into the horizontal movement.

Since the lower end of the body portion 110 is bent in the horizontal direction, the chain portion 120 converts the vertical movement into the horizontal movement accordingly.

The expansion guide part 130 is formed to be stretchable in the horizontal direction, and the length thereof is variable in the horizontal direction according to the movement of the chain part 120.

 The expansion guide part 130 may be composed of a plurality of plates sliding between each other, or may be composed of a plurality of pipes folded between each other.

In the illustrated embodiment, the expansion guide 130 is shown on both sides of the chain portion 120. The elastic guide part 130 may be provided on the bottom of the chain part 120, or may be provided on both the bottom and both side surfaces thereof.

The dummy bar 150 may be connected to an upper end of the chain part 120 accommodated in the body part 110. The dummy bar 150 is formed to be capable of lifting up and down along the longitudinal direction of the body portion 110 like the chain.

When the cutting device 100 according to the present invention lowers the dummy bar 150 connected to the upper end of the chain part 120 in the state as shown in FIG. 1, the chain part 120 extends in the longitudinal direction of the body part 110. Move along. When the chain part 120 descends, the horizontal end of the chain part 120 connected to the cutting head part 140 is pushed in the horizontal direction, and thus the elastic guide part 130 extends in the horizontal direction.
