[0022] The present invention will be further described below with reference to the accompanying drawings: Example

[0023] Reference Figure 1-5 A cross-shaped splitter blade for a wood splitter includes a base 1, a vertical blade 2, a first horizontal blade 3, and a second horizontal blade 4. The vertical blade 2 is inserted and installed on the front side of the base 1, and its two ends are fixedly connected to the two ends of the base 1 by fasteners 5. Specifically, fastener 5 is a high-strength bolt of type M8×30 ​​(this type is only an example; the actual type can be selected according to the specific load-bearing requirements of the wood splitter). This bolt has sufficient strength and tensile strength to ensure a stable connection between the vertical blade 2 and the base 1, allowing it to withstand significant impact forces during wood splitting without loosening. The first horizontal blade 3 and the second horizontal blade 4 are inserted and installed on both sides of the base 1, respectively. The first horizontal blade 3 and the second horizontal blade 4 are fixedly connected to the base 1 by fasteners 6, which are also high-strength bolts of type M6×25 (again, this is an example type; it can be adjusted according to actual conditions) to ensure the reliability of the connection between the horizontal blades and the base.

[0024] The vertical blade 2, the horizontal blade 1 and the horizontal blade 2 form a cross shape through the base 1. This cross-shaped structure allows the splitting blade to apply force to the wood from multiple directions when splitting firewood, improving the efficiency of splitting firewood, while ensuring the uniformity and stability of splitting firewood.

[0025] A T-shaped slot 11 is formed from top to bottom on the front side of the base 1. The width of the T-shaped slot 11 is 15cm (the size is for example only and can be determined according to the actual size of the tool and installation requirements), and the depth is 20cm, providing a stable locking position for the vertical tool 2. On both sides of the base 1 near the T-shaped slot 11, there are splicing grooves 12, each 10cm wide and 10cm deep. These splicing grooves cooperate with certain structures on the horizontal tool to enhance the overall structural stability. The base 1 is locked to the vertical tool 2 through the T-shaped slot 11. This locking method facilitates installation and disassembly, and at the same time, it can restrict the movement of the vertical tool 2 to a certain extent, ensuring its stability during operation.

[0026] Mounting grooves 7 are respectively provided on the upper part of the two rear sides of the base 1. The mounting grooves 7 are 12cm wide and 15cm deep. T-shaped retaining rails 10 are integrally formed in the mounting grooves 7 and the base 1. The T-shaped retaining rails 10 are 8cm wide and 10cm high. The base 1 is engaged with the corresponding transverse cutter 3 and transverse cutter 4 through the mounting grooves 7 and the T-shaped retaining rails 10. This structure allows the transverse cutters to be accurately mounted on the base and is not easy to fall off during operation.

[0027] The upper and lower sides of the rear of the base 1 are respectively provided with connecting holes 8 for connecting to the fastener 5. The diameter of the connecting hole 8 is 8.5cm (matching the bolt diameter of the fastener 5) so that the fastener 5 can pass through smoothly and be connected and fixed.

[0028] The bottom of the mounting groove 7 of the base 1 is provided with a connecting hole 9 for connecting with the fixing part 6. The diameter of the connecting hole 9 is 6.5cm (matching the bolt diameter of the fixing part 6), which is used to fix the transverse cutter.

[0029] A raised strip 13 is formed between the splicing groove 12 and the mounting groove 7. The raised strip 13 is 5cm high and 8cm wide. Its function is to cooperate with the notch on the transverse cutter to further enhance the connection stability between the transverse cutter and the base and prevent the transverse cutter from shaking during operation.

[0030] A one-piece T-shaped clamping plate 21 is provided on the rear side of the vertical cutter 2. The T-shaped clamping plate 21 is 14cm wide and 18cm high. The vertical cutter 2 is engaged with the T-shaped clamping plate 21 and the T-shaped clamping groove 11. This engagement structure is simple and reliable, and can quickly position and install the vertical cutter. The T-shaped clamping plate 21 has a connecting hole 3 22 corresponding to the connecting hole 8. The connecting hole 3 22 has a diameter of 8.5cm. The connecting hole 3 22 is connected to the fixing component 5. By tightening the bolts, the vertical cutter 2 is firmly fixed to the base 1.

[0031] The transverse blade 3 and transverse blade 4 have the same structure. The outer corner of transverse blade 3, away from the blade edge, has a chamfer 31 with an angle of 45°. The chamfer prevents excessive stress concentration when the blade collides with the wood or other parts during firewood splitting, thus reducing the risk of blade damage and extending blade life. One end of transverse blade 3 has a connecting hole 32 corresponding to connecting hole 9. The diameter of connecting hole 32 is 6.5cm. Connecting hole 32 connects to fastener 6 to fix the transverse blade to the base. The end of transverse blade 3 near connecting hole 32 has a T-shaped opening 33 and a notch 34. The T-shaped opening 33 is 7cm wide and 9cm high. Transverse blades 3 and 4 engage with the corresponding T-shaped rail 10 through the T-shaped opening 33, ensuring accurate installation of the transverse blades on the base. Transverse blades 3 and 4 also engage with the corresponding protruding strip 13 through the notch 34, further enhancing connection stability. A protrusion 35 is formed between the blade of the transverse blade 3 and the notch 34. The protrusion 35 is 3cm high and 6cm wide, and it is cut into the corresponding splicing groove 12. This structure makes the fit between the transverse blade and the base more tight, improving the overall structural strength. The head of the blade of the transverse blade 3 is in close contact with one side of the root of the blade of the vertical blade 2. This design allows the vertical and transverse blades to work together when splitting firewood, applying force to the wood from different directions and improving the splitting effect.

[0032] In this embodiment, during use, firstly, align the T-shaped clamping plate 21 of the vertical cutter 2 with the T-shaped groove 11 on the base 1, insert it, and align the connecting hole 3 22 with the connecting hole 1 8. Then, use the fastener 5 (high-strength M8×30 ​​bolt) to pass through the connecting hole 3 22 and the connecting hole 1 8 and tighten it to fix the vertical cutter 2 on the front side of the base 1. Next, align the T-shaped openings 33 of the horizontal cutter 1 3 and the horizontal cutter 2 4 with the T-shaped rails 10 on the base 1, and align the notch 34 with the protruding strip 13. Insert them into the mounting groove 7, align the connecting hole 4 32 with the connecting hole 2 9, and use the fastener 2 6 (high-strength M6×25 bolt) to pass through the connecting hole 4 32 and the connecting hole 2 9 and tighten it to complete the installation of the horizontal cutter. At this time, the vertical cutter 2, the horizontal cutter 1 3, and the horizontal cutter 2 4 form a complete cross-shaped splitting structure through the base 1, which can be installed on a wood splitter for wood splitting operations. During the wood-splitting process, the vertical and horizontal blades work together to apply force to the wood from multiple directions, achieving an efficient and uniform wood-splitting effect.

[0033] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
