[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0022] Example 1: Please refer to Figure 1 - Figure 2 This embodiment of a portable manual heavy-duty wood cutter includes a frame 1 and a cutting blade 2. One end of the cutting blade 2 is movably connected to the top of one end of the frame 1, and the other end of the cutting blade 2 is fixedly connected to a short handle 3. A protrusion 7 is fixedly connected to the top of the cutting blade 2, and the protrusion 7 is located at the top of the cutting blade 2 and away from the fixed pin 9. A long handle 4 is provided at one end of the short handle 3. A ring 8 is provided at one end of the frame 1, and two bases 11 are fixedly connected to the bottom of both ends of the frame 1.

[0023] In this method, by first placing the wood on top of the fixed frame 1, then holding the short handle 3 and pressing it down, using the cutting blade 2 as a lever and the top of the fixed frame 1 as the fulcrum, according to the lever principle, a larger effect can be produced with a smaller force, reducing the physical exertion of manually cutting wood and improving cutting efficiency.

[0024] The wood is initially cut by pressing down on the short handle 3. When the short handle 3 is pressed down and not moved, the hammer is used to strike the protrusion 7 to further apply impact force. The combination of the two force application methods can deal with wood of different hardness and size and quickly complete the cutting task.

[0025] With the ring 8 installed, the wood cutter can be fixedly hung on the wall or next to the wood-burning stove, or near the shed where the wood is stored, when not in use, for easy access next time;

[0026] Wood cutters are widely used, making it convenient for outdoor enthusiasts and woodworkers to cut and split wood. They can also be taken to camping, barbecues, picnics, outdoor dinners, and many other occasions. In winter, the cutter can be used to split firewood into suitable sizes and prepare enough firewood for emergencies.

[0027] Furthermore, a fixing pin 9 is provided at the top of one end of the fixing frame 1. The cutting blade 2 is rotatably connected to the top of one end of the fixing frame 1 through the fixing pin 9. The cutting blade 2 can rotate 180 degrees and adopts a lever-type wood cutting design, which can rotate freely 180 degrees, thus making it easier to split the wood.

[0028] Furthermore, a pad 12 is fixedly connected to one end of the top of the fixing frame 1, and the bottom of one end of the fixing pin 9 is in contact with the top of the pad 12. By setting the pad 12, it can play a role in preventing collision. When the cutter is transported, stored or accidentally collided, the pad can act as a buffer barrier to absorb the impact energy, prevent the cutter 2 from being damaged by collision, and extend its service life.

[0029] Furthermore, a serrated strip 10 is provided on the top of the fixing frame 1. The serrated strip 10 is located below the blade of the cutting knife 2.
