TECHNICAL FIELD

[0001] The utility model relates to garden tool technical field especially relates to a high strength plastic blade for garden tool. BACKGROUND

[0002] In the field of garden tools, blades are indispensable important components. Traditional garden tool blades are usually made of metal. Although metal blades have high hardness and sharpness, they also have some obvious shortcomings. First, metal blades are prone to chipping or breaking during use, especially when encountering hard objects such as stones and tree roots, which not only affects the normal use of the tool but also may cause harm to the user. Second, metal blades are heavy, and long-term use can increase the user's fatigue and reduce work efficiency. In addition, metal blades can rust in humid environments, affecting their service life and performance.

[0003] With the continuous development of material science, the performance of plastic materials has been greatly improved. Some high-performance plastics have already met the use requirements of garden tool blades in terms of strength and toughness. However, there are no widely used high-strength plastic garden tool blades on the market yet. Existing plastic blades either lack sufficient strength to withstand normal garden work intensity or have design flaws that prevent them from being securely connected to the connecting handle, causing the blade to loosen or even fall off during use, affecting the use effect and safety. SUMMARY

[0004] The present application provides a high-strength plastic blade for garden tools that can ensure sufficient strength and durability, and can be quickly and securely connected to the connecting handle through reasonable structural design, thereby improving the use performance and safety of garden tools and meeting market demand.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme:

[0007] Preferably, the transverse section is located at the tip of the blade body, the tip of the blade body is arc-shaped, and the blade body gradually thins from the middle to both sides to form the blade edge. The arc-shaped transverse section at the tip of the blade body greatly enhances the structural strength of the blade body. During cutting, the arc-shaped structure can effectively disperse stress, significantly reducing the risk of blade body damage due to local stress concentration. The blade edge formed by the gradual thinning of the blade body from the middle to both sides can more efficiently concentrate force during cutting, greatly reducing cutting resistance.

[0008] Preferably, the tail of the knife has a first arc end and a second arc end, and the first arc end and the second arc end form an 8-shaped structure, which can evenly disperse stress to the two arc ends when the knife body is subjected to external force from different directions, such as torsional force or impact force during cutting, thereby effectively avoiding stress concentration at a certain point, greatly enhancing the structural stability of the tail of the knife, and significantly reducing the possibility of damage to the tail of the knife.

[0009] Preferably, the tail of the knife is provided with a connecting hole, and the inner side of the connecting hole is provided with a first stable groove and a first stable end matched with the connecting handle.

The design of the placing plate and the fixing plate provides a stable and reliable installation basis for the blade, and the fixed connection between the placing plate and the fixing plate through the connecting member makes the connecting handle form a stable overall structure, which can withstand greater external force and is not prone to deformation or damage during use. Through the connecting handle, not only the installation efficiency and stability of the blade are improved, but also the durability of the entire garden tool is enhanced.

[0012] Preferably, the placing groove is provided with a connecting end matched with the connecting hole, the connecting end is provided with a second stable groove and a second stable end, the first stable groove is matched with the first stable end on the tail of the knife, and the second stable groove is matched with the first stable end on the tail of the knife. The accurate matching of the connecting end in the placing groove with the connecting hole of the tail of the knife provides preliminary positioning and fixing for the connection of the blade and the connecting handle, and the second stable groove and the second stable end on the connecting end are matched with the first stable groove and the first stable end on the tail of the knife, forming a multiple stable structure.

[0013] Preferably, the positioning member comprises a moving block, the lower end of the moving block is provided with a pressing plate, a spring is sleeved on the moving block, the spring is above the pressing plate, and the moving end is provided with a positioning end away from the pressing plate.
