An apparatus for clamping a film, comprising:

• a first bar configured to fix a first side portion of the film;
• a second bar configured to fix a second side portion of the film, wherein the second side portion is opposite to the first side portion;
• a third bar adjacent and connected to the second bar, wherein the third bar and the first bar are respectively located on two opposite sides of the second bar, and the third bar is configured to pull the film from the second side portion of the film through the second bar, and wherein a first end portion and a second end portion opposite to the first end portion in each of the first bar and the third bar respectively have a first through hole and a second through hole;
• at least one elastic element having a first end and a second end opposite to each other and respectively disposed on the second bar and the third bar, wherein the at least one elastic element is configured to provide the film with pull buffer;
• a first linking bar, wherein two opposite ends of the first linking bar are respectively disposed in the first through holes of the first bar and the third bar;
• and
• a second linking bar, wherein two opposite ends of the second linking bar are respectively disposed in the second through holes of the first bar and the third bar,
• wherein the first through hole and the second through hole of the first bar pass through the first bar from a top surface of the first bar to a bottom surface of the first bar, and the first through hole and the second through hole of the third bar pass through the third bar from a top surface of the third bar to a bottom surface of the third bar, such that the ends of the first linking bar and the ends of the second linking bar can be removed from the first bar and the third bar upwardly or downwardly.
