[0001] The utility model relates to the technical field of garden tools, in particular to a grass trimmer. Background Art

[0002] With the continuous development of landscaping and agriculture, lawn mowers, as a commonly used lawn mowing tool, are used more and more frequently. Existing lawn mowers have some shortcomings in design, especially in terms of safety and ease of operation. During use, traditional lawn mowers are prone to safety accidents such as flying stones injuring people due to the lack of effective safety protection measures. In addition, the installation method of the protective cover of the lawn mower is complicated, which is not convenient for users to quickly replace and maintain, which affects work efficiency to a certain extent. In order to solve these problems, there are continuous new attempts and technical improvements in the industry. For example, some lawn mowers use fixed or detachable protective covers to improve safety, but these designs often sacrifice operational flexibility or ease of installation. Therefore, it is very necessary to provide a lawn mower with a detachable protective cover.

[0003] However, one of the shortcomings of the prior art is that the connection structure between the protective cover and the grass trimmer body is not stable enough and is not convenient to disassemble. Utility Model Content

[0004] The utility model aims to solve at least one of the above technical problems.

[0005] In order to solve the above problems, the first purpose of the utility model is to provide a grass trimmer.

[0006] To achieve the first purpose of the utility model, an embodiment of the utility model provides a lawn mower, which includes: a lawn mower body; a protective cover, the protective cover and the lawn mower body are detachably connected through a slot assembly, the slot assembly includes: a fixed block, the fixed block is arranged on the lawn mower body; a fixed slot, the fixed slot is arranged on the protective cover, and the fixed slot cooperates with the fixed block.

[0007] When the mower is in use, the protective cover can effectively protect the user from flying stones and debris. The matching design of the fixing block and the fixing slot ensures the stability of the protective cover during operation, thereby reducing safety risks. Through the design of the card slot assembly, users can quickly install and remove the protective cover without tools, which improves the efficiency of maintenance and cleaning, and makes it easier to replace the appropriate protective cover in different working environments. The matching design of the fixing block and the fixing slot in the card slot assembly provides a simple and firm mechanical connection method to prevent the protective cover from accidentally falling off during use and ensure the reliability of the connection.

[0008] In the above technical solution, the fixing block includes: a first fixing block; a second fixing block, and the first fixing block and the second fixing block are connected to each other.

[0009] By dividing the fixing block into two parts and connecting them to each other, the structural strength of the entire slot assembly can be increased. This design disperses the force at the connection, thereby improving the stability and durability of the connection between the protective cover and the lawn mower body. The cooperation of the two fixing blocks can cooperate more closely with the fixing slot, further preventing the protective cover from shaking or accidentally falling off during operation, ensuring safety. When damaged or in need of replacement, users can more easily disassemble and replace a single fixing block without having to handle the entire fixing block combination, which simplifies maintenance work and reduces downtime. Therefore, designing the fixing block as a first fixing block and a second fixing block that are connected to each other not only improves the reliability and safety of the product, but also brings convenience to production, assembly, maintenance and replacement.

[0010] In any of the above technical solutions, the slot assembly also includes: a first slider, which is arranged at one end of the first fixed block away from the second fixed block; a second slider, which is arranged at one end of the second fixed block away from the first fixed block; wherein the first slider and the second slider cooperate with the fixed slot.

[0017] The connection between the first connection part and the second fixing block enhances the structural strength of the entire slot assembly, making the connection between the protective cover and the mower body more stable, reducing the risk of deformation or damage during high-intensity operation. The close fit between the first connection part and the second fixing block ensures the stability of the protective cover during installation, prevents shaking or loosening during operation, and improves overall reliability. When the mower is impacted during operation, the first connection part helps to evenly distribute the force to the first fixing block and the second fixing block, reducing the burden on a single component and thus reducing the risk of damage.

[0018] In any of the above technical solutions, the second fixing block is provided with a second connecting portion, and the second connecting portion is connected to the first connecting portion.

[0019] The cooperation of the second connection part with the first connection part enhances the connection rigidity between the fixing blocks, ensures the close connection between the protective cover and the mower body, and improves the stability and durability of the overall structure. The first connection part is connected to the second connection part, which helps to evenly distribute the load between the first fixing block and the second fixing block, thereby reducing local stress concentration and wear and extending the service life of the components. The combination of the second connection part and the first connection part provides a double locking mechanism to prevent the fixing block from accidentally loosening during use, thereby improving the safety of operation.

[0020] In any of the above technical solutions, the second connecting portion is connected to the first connecting portion via a fastener.

[0021] Connecting the first connection portion to the second connection portion by means of a fastener, such as a bolt, can improve the connection strength between the first fixing block and the second fixing block, thereby improving the stability and durability of the overall structure.

[0022] In any of the above technical solutions, the protective cover is provided with an avoidance portion, and the avoidance portion is arranged at one end of the protective cover close to the fixing groove.

[0023] When the fixing block is combined with the fixing slot, the avoidance portion fits against the edge of the lawn mower body, making the fixing block and the fixing slot more tightly combined, thereby enhancing the structural strength of the entire slot assembly, making the connection between the protective cover and the lawn mower body more stable, and reducing the risk of deformation or damage during high-intensity operations.

[0024] In any of the above technical solutions, the protective cover is provided with a side wall, and the side wall is arranged at one end of the protective cover away from the fixing groove.

[0025] The sidewalls increase the protective range of the shield, providing more comprehensive coverage to protect the user from flying debris, grass clippings, stones and other objects that may cause injury. The presence of the sidewalls enhances the overall structural strength of the shield, making the shield more resistant to external impact and wear during use, extending its service life.
