The lower jig 200 may be cut to the correct depth when the cutter 100 automatically moves and does not move when cutting, but also does not occur deformation under pressure generated by the cutting blade 400. The lower jig 200 may not be deformed even when the upper jig 300 or 500 is pressed from the upper portion of the headliner 10 of the car to fix the headliner 10 of the car. The lower jig 200 may be made of metal or the like in order to reduce the degree of deformation, but is not limited thereto.

The lower jig 200 may vary in shape depending on the shape of the headliner 10 of the vehicle. Since the lower jig 200 can accurately fix the headliner 10 when the shape corresponds to the headliner 10 of the vehicle, the shape of the headliner 10 of the vehicle is different according to the vehicle type. Its shape may change.

The lower mold jig 200 may fix the vehicle headliner 10 better if the shape of the headliner 10 is exactly the same, but is not limited thereto. The lower jig 200 may have a shape that can be supported without being deformed according to the movement of the cutter 100 from the lower part even if the shape of the headliner 10 of the vehicle is different. The lower jig 200 may be freely deformed within a range capable of fixing the headliner 10 of the vehicle.
