Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0016] like figure 1 , figure 2 and image 3 A labor-saving punching machine is shown, which includes a base 1, a handle 2, a cutter 3 and a bracket 4 (of course, it also includes other parts, but since it does not involve the invention of the present invention, it will not be repeated here), The bracket 4 is fixedly connected to the base 1, the handle 2 is hinged to the bracket 4, the cutter 3 is slidably connected to the bracket 4, and the base 1 is provided with punching holes 11 corresponding to the cutter 3 one by one. , the base 1 directly below the cutter 3 is provided with a bevel 12, and the angle a between the axis of the cutter 3 and the bevel 12 is less than 90° (83° in this example, it can also be 80°, 81°, 85° or 86°, etc., that is, the angle between the slope and the horizontal plane is 7°, 10°, 9°, 5° or 4°), the punching ho...

Abstract

The invention discloses a labor-saving perforating machine, which comprises a base (1), a handle (2), tools (3) and a support (4), wherein the support (4) is fixedly connected with the base (4); the handle (2) is hinged to the support (4); the tools (3) are connected to the support (4) in a sliding way; the base (1) is provided with punched holes (11) which correspond to the tools (3) one by one; a bevel (12) is arranged on the base (1) right below the tools (3); the included angle a between the axes of the tools (3) and the bevel (12) is smaller than 90 degrees; the punched holes (11) are formed in the bevel (12). Compared with the prior art, the force used when the labor-saving perforating machine is used for perforating is at least 10 % smaller than the force used when a labor-saving perforating machine in the market is used for perforating, so that the labor-saving perforating machine has the characteristics of fewer parts, simple structure, lower cost, easiness in assembly and convenience in use.

Description

technical field [0001] The invention belongs to the technical field of office stationery, in particular to a labor-saving punching machine for punching paper. Background technique [0002] At present, the punching machine is widely used in daily office because of its advantages such as simple and convenient use, low price, and small and exquisite appearance. The labor-saving punching machine is to make the user save more effort and have higher punching efficiency when using it. However, the labor-saving punching machines of the prior art are designed to reduce the torque of the cutter head and increase the distance of the handle torque to save labor. This labor-saving structure has the following problems: There are many parts, the structure is more complicated, the cost is higher, and the assembly is more complicated, resulting in lower production efficiency and higher production cost; 2. Due to the small torque between the fulcrum and the cutter head, the height of the han...
