The fracturing apparatus includes a first board portion, a pressing element, a first suction device, a second board portion, a second suction device, and a cylinder. The first suction device is secured to the first board portion. The second board portion is rotatably connected to the first board portion. The second suction device is secured to the second board portion. The pressing element is secured to the first board portion and disposed between the first board portion and the second board portion. The cylinder is located on the first board portion and includes a piston rod rotatably connected to the second board portion. When the piston rod extends, the second board portion is pressed by the piston rod and swiveled about the first board portion. ## Claims ### Claim 1 A fracturing apparatus comprising: a first board portion; a first suction device secured to the first board portion; a second board portion rotatably connected to the first board portion; a second suction device secured to the second board portion; a pressing element secured to the first board portion and disposed between the first and second board portion; and a cylinder disposed on the first board portion, wherein the cylinder comprises a piston rod rotatably connected to the second board portion, and when the piston rod extends, the second board portion is pressed by the piston rod and swiveled about the first board portion. ### Claim 2 (depends on 1) The fracturing apparatus as claimed in claim 1 further comprising: a moving device connected to the first board portion for controlling a moving direction of the first board portion. ### Claim 3 (depends on 1) The fracturing apparatus as claimed in claim 1 further comprising a first fixing element, wherein the first board portion comprises a first positioning hole, the second board portion comprises a second positioning hole corresponding to the first positioning hole, and the first fixing element extends through the first board portion and the second board portion through the first positioning hole and the second positioning hole. ### Claim 4 (depends on 3) The fracturing apparatus as claimed in claim 3, wherein the first fixing element comprises a bolt. ### Claim 5 (depends on 1) The fracturing apparatus as claimed in claim 1, wherein the second board portion comprises a connecting part connected to the piston rod. ### Claim 6 (depends on 5) The fracturing apparatus as claimed in claim 5 further comprising a second fixing element penetrating the connecting part and the piston rod. ### Claim 7 (depends on 6) The fracturing apparatus as claimed in claim 6, wherein the second fixing element comprises a bolt. ### Claim 8 (depends on 5) The fracturing apparatus as claimed in claim 5, wherein the second board portion and the connecting part are formed as a single piece. ### Claim 9 (depends on 1) The fracturing apparatus as claimed in claim 1, wherein the first suction device comprises a first nozzle. ### Claim 10 (depends on 9) The fracturing apparatus as claimed in claim 9, wherein the second suction device comprises a second nozzle. ### Claim 11 (depends on 10) The fracturing apparatus as claimed in claim 10, wherein the first nozzle, the second nozzle, and the pressing element have respective end surfaces disposed substantially within the same horizontal level when the piston rod does not extend. ### Claim 12 (depends on 1) The fracturing apparatus as claimed in claim 1, wherein the material of the first board portion and the second board portion comprises aluminum or stainless steel. ### Claim 13 (depends on 1) The fracturing apparatus as claimed in claim 1, wherein the material of the pressing element comprises plastic or rubber. ### Claim 14 (depends on 1) The fracturing apparatus as claimed in claim 1, wherein the pressing element has a rectangular cross section. ### Claim 15 (depends on 1) The fracturing apparatus as claimed in claim 1, wherein the first board portion has an L-shaped cross section. ### Claim 16 (depends on 1) The fracturing apparatus as claimed in claim 1, wherein the second board portion has an L-shaped cross section.
