New description: [New technical field] i This creation system belongs to a kind of punching machine, especially a kind of punching machine which can save effort. The user can use this punching machine to easily punch holes in thick paper stack. [Prior Art] A punching machine is used to make a plurality of perforations on a sheet of paper so that the fixing members on the sheet-fed booklet pass through the perforations to fix the sheet. The existing punching machine forms two perforations on the top surface of a hollow base, and two fixing frames are arranged on the top surface of the base. A gap is formed between the fixing frame and the top surface of the base to accommodate the paper, and is pivoted on the two fixing frames. An upper cover is respectively provided with a spring between the upper cover and the two solid trusses, so that the upper cover can maintain a state of being raised when not subjected to other external forces, and the two fixed frames are respectively provided with punches that can slide vertically, each The punching system is pivoted with the upper cover, and the bottom end is respectively formed with two annular cutting edges facing the base. However, the design method of the puncher only uses the general moment force to force the upper cover as the force arm to press down to punch, and when punching the thick paper stack, the user has insufficient arm. : It is extremely laborious to press. In addition, since the two punching blades of the punching machine are located in the same-high setting, when punching, the two punching blades are simultaneously pressed on the paper table... When the stack thickness is too large, the user must have a heart: the yoke pressure - the maximum force can make the edges of the two punches pass through the stack of papers at the same time. [New content] M288231 Therefore, the creator passes through the two cutting edges of the existing punching machine at the same time. The paper makes it difficult to apply the perforation of the thick stack of sheets, and improves its shortcomings and shortcomings, thereby creating a labor-saving punching machine. The main purpose of this creation is to provide a labor-saving punching machine, which is indirectly pivoted on the punch by the two-force arm assembly, so that when punching, the force of the upper cover can be applied to the traditional punching machine. The strength of the upper cover is smaller. In order to achieve the above purpose, the foregoing labor-saving punching machine comprises: two bases, two perforations are formed on the base, and two fixing brackets respectively aligning the perforations are arranged on the top surface of the base, and between the fixing brackets and the base Forming a gap for respectively accommodating the paper to be perforated; the two punches are respectively vertically slidably disposed at the bottom end of the system to form a blade respectively; μ two arm assemblies are respectively pivoted at each punch In the sub-arm, each arm assembly includes: a lower arm is pivoted on the corresponding punch; and a boil is dragged on the lower arm; and an upper cover is pivoted on the two arm assemblies. On the upper cover, a part is formed on the upper cover, and two pivoting arms are protruded forwardly from the front end of the pressing portion. Each of the trailing arms is pre-food and is pivoted on the fixing brackets of the base, and each pivoting arm is pressed close to the pressing arm. The upper part is pivoted on the upper arm respectively. Between each of the trailing arms and the corresponding fixing frame, an elastic member α is arranged to raise the upper cover pressing portion. According to the above technical means, the upper cover is indirectly pivoted/supported by the force arm assembly. The force generated by the upper cover is transmitted to the upper arm and the lower arm. When the upper arm and the lower arm are longer, the torque is generated. Large, and the force on the M288231 可 can be made smaller than the force applied to the upper cover of the traditional puncher, in order to achieve the labor-saving effect 'further' so that the blade of the punch is at different levels, i make the knife The knife cuts the paper differently, so the maximum force required for the user to punch the hole is only half of the force required to use the hole of the conventional puncher, so the user can easily cut the stack of thick paper without much effort. . Each of the two fixing frames has two vertical perforations formed on the side plates/side plates of the opposite sides of the corresponding punches, and two side plates on the lower arms are respectively formed on two sides of the corresponding fixing frame. Each of the side plates respectively has a transversely penetrating shaft hole formed in each of the punches of the car hole, and the first hole is respectively inserted into the first hole of the corresponding fixed frame. The first-pivot system passes through the shaft hole of the corresponding lower arm side plate. The front ends of the two side plates of each of the fixing frames are respectively formed with a pivot groove, and the front ends of the two side plates of the respective arms are respectively formed with a pivot groove. Each of the two sides of the front end of each of the pivoting arms of the upper cover is respectively formed with a through shaft. "The second pivot is respectively sleeved on the shaft hole of the pivoting arm, and each of the second systems is located on the side of the corresponding fixed frame and correspondingly The two punching blade edges of the lower arm side plate are respectively located at two different horizontal levels. The springs of the elastic members are respectively one of the teeth to be worn on the corresponding two pivots. [Embodiment] Please refer to the first and second figures.
