[0044] Please refer to Figures 1 to 6 The utility model relates to a garden tool, including a joystick 100, a working part 200 and a main machine 300. The joystick 100 is extended in the front-back direction and is in the shape of an elongated cylinder. The working part 200 is arranged at the front of the joystick 100, and the main machine 300 is arranged at the rear of the joystick 100. The working part 200 includes a shell 210, a motor 220 and a cutting piece 230, wherein the shell 210 is connected to the joystick 100, the motor 220 is accommodated in the shell 210, the motor 220 has an output end, and the cutting piece 230 is connected to the output end of the motor 220. The motor 220 drives the cutting piece 230 through the output end to operate on grass and lawns. The main machine 300 includes a battery pack 310, and the battery pack 310 is used to supply power to the motor 220, and the power is converted into mechanical energy by the motor 220 and output to the cutting piece 230. The battery pack 310 can be detachably mounted on the host 300 and can be electrically connected to the motor 220 via a cable stored inside the joystick 100. In addition, the host 300 can further include a control unit to control the operation of the motor 220.

[0045] In order to improve the safety of the garden tool, the working part 200 of the garden tool is provided with two shields. Among them, the inner shield 240 is located outside the cutting piece 230 and is covered by the cutting piece 230; and the outer shield 250 is located outside the inner shield 240 and is covered by the inner shield 240. The outer edges of the inner shield 240 and the outer shield 250 both have a baffle bent downward, and the baffle of the inner shield 240 is located inside the baffle of the outer shield 250. It should be noted that the above-mentioned inner side or outer side is defined based on the position of the cutting piece 230. For example, the outer shield 250 is located outside the inner shield 240, which means that it is located farther away from the cutting piece 230 than the inner shield 240.

[0046] The inner shield 240 and the outer shield 250 are fixed to the housing 210, respectively. The inner shield 240 is fixed to the housing 210 at one end thereof to form a stable connection with the housing 210; the outer shield 250 is also fixed to the housing 210 at one end thereof to form a stable connection with the housing 210. The outer shield 250 and the inner shield 240 are not easy to fall off, and the deformation or damage of any single shield will not affect the other shield. The installation method of the shield makes its structure more stable, further improving the overall safety of the garden tool.

[0047] The double guard can improve the safety of the garden tool, and further provide conditions for meeting the safety requirements of more types of cutting parts 230. For example, when the cutting part 230 is a blade or a circular saw blade, there are different requirements for the guard, which are mostly based on local safety regulations and will not be elaborated.

[0048] In order to reinforce the inner shield 240, in one embodiment, a limiting groove 241 is provided at one end of the inner shield 240, and a limiting block 211 plugged into the limiting groove 241 is convexly provided on one side of the shell 210. When installing the inner shield 240, the inner shield 240 is translated toward the shell 210 so that the limiting block 211 is inserted into the limiting groove 241. The limiting groove 241 is limited by the limiting block 211, thereby preventing the inner shield 240 from swinging. By providing the limiting groove 241 and the limiting block 211 that cooperate with each other, the use of screws can also be reduced, making the disassembly and assembly of the inner shield 240 more convenient. Preferably, the limiting groove 241 at least has a groove wall that is tightly attached to the two side walls of the limiting block 211 in the horizontal direction after being plugged into the limiting block 211.

[0049] Furthermore, the inner shield 240 is reinforced by screws. Specifically, the limit block 211 is provided with a first screw hole (not marked in the figure); the inner shield 240 is provided with a connecting piece 242, the connecting piece 242 is located in the limit groove 241, and the connecting piece 242 is provided with a first through hole 243 corresponding to the first screw hole; the working part 200 also includes a first screw 260, and the first screw 260 passes through the first through hole 243 and is screwed into the first screw hole. By arranging the connecting piece 242 in the limit groove 241, the inner shield 240 is fixed to the housing 210 through the fixing of the connecting piece 242 and the limit block 211, and then the plug-in connection between the inner shield 240 and the housing 210 is fixed with screws to enhance the fixing effect. Preferably, the limit block 211 is provided with a groove that at least partially accommodates the connecting piece 242. When the limit block 211 is inserted into the limit groove 241, the connecting piece 242 is inserted into the above-mentioned groove, which plays a double limiting role.

[0050] Further, the outer shield 250 is fixed by screws. Specifically, the limit block 211 is provided with a pair of second screw holes (not marked in the figure); the outer shield 250 is provided with a pair of second through holes 251 corresponding to the second screw holes; the working part 200 also includes a second screw 270, and the second screw 270 passes through the second through hole 251 and is screwed into the second screw hole. It should be noted that the through hole on the connecting piece 242 or the outer shield 250 can also have an internal thread. Through the two-point positioning of a pair of screws, the outer shield 250 is fixed to the housing 210, and there is no need to set up a positioning structure separately, which saves space. Among them, the first screw hole is located between the pair of second screw holes, and correspondingly, the first screw 260 is located between the pair of second screws 270, so that the positioning structure of the inner shield 240 can be limited to not exceed the range of the positioning structure of the outer shield 250. For example, the positioning structure of the inner shield 240 is also covered below the outer shield 250, which saves space and protects the plug-in structure and screw fixing structure of the inner shield 240.

[0051] Furthermore, the screwing direction of the first screw 260 is opposite to the screwing direction of the second screw 270. When the first screw 260 is screwed into the first screw hole from bottom to top, the second screw 270 is screwed into the second screw hole from top to bottom; conversely, when the second screw 270 is screwed into the second screw hole from bottom to top, the first screw 260 is screwed into the first screw hole from top to bottom. Staggering the screwing direction can facilitate the independent disassembly of the inner shield 240 or the outer shield 250. For example, when the inner shield 240 has only one first screw 260 tightened from bottom to top, the disassembly of the inner shield 240 only needs to be disassembled from the bottom of the first screw 260; for example, when the outer shield 250 has only a pair of second screws 270 tightened from top to bottom, the disassembly of the outer shield 250 only needs to be disassembled from the top of the pair of second screws 270. On the contrary, screws with the same screwing direction will not only fix the two shields at the same time, making the disassembly and assembly of a single shield more cumbersome, but also make it difficult to distinguish the screws corresponding to any shield when disassembling and assembling the shields.

[0052] In one embodiment, the housing 210 includes a main body 212 and an extension portion 213 connected to the main body 212 and extending outward, and the extension portion 213 is sleeved on the front end of the joystick 100, so that the joystick 100 is connected to the housing 210. The extension portion 213 can be provided with a screw fastening device to reinforce the sleeve fixation with the joystick 100. Among them, the first screw hole is located in the projection range of the extension portion 213 along the axial direction of the motor 220, that is, the first screw 260 corresponding to the first screw hole is also located in the projection range of the extension portion 213 along the axial direction of the motor 220. The axial direction of the motor 220 is the axial direction of the output shaft of the motor 220. In this embodiment, it can be understood as a projection to one side of the cutting member 230. The projection area of ​​the extension portion 213 in this direction is limited by the length and width of the horizontal cross section of the extension portion 213, and the projection position is limited by the position of the extension portion 213 relative to the main body 212 of the housing 210. Therefore, the positions of the first screw hole and the first screw 260 are restricted, thereby ensuring that the positioning structure of the inner shield 240 is close to the main body 212 of the shell 210, the bridge structure between the positioning structure and the shell 210 is shorter, and the shield is more stable.

[0053] It should be noted that the aforementioned positioning structure includes screw holes, screws, through holes, limit blocks 211 and limit grooves 241 and their combinations; the bridge structure is a structural part connecting the positioning structure and the protective cover or shell 210.

[0054] In one embodiment, a gap is left between the inner shield 240 and the outer shield 250. The inner shield 240 and the outer shield 250 are not in contact with each other, and the deformation or damage of any single shield will not affect the other shield.

[0055] In one embodiment, the inner shield 240 is a metal shield, and the outer shield 250 is a plastic shield. Further, the inner shield 240 is an iron shield.

[0056] In a preferred embodiment, the garden tool is a brush cutter. Of course, in other embodiments, the garden tool can also be other garden tools such as a grass cutter and an edge trimmer.

[0057] The utility model is not limited to the above specific implementations. Those skilled in the art can easily understand that there are many alternatives to the gardening tool of the utility model without departing from the principle and scope of the utility model. The protection scope of the utility model shall be based on the content of the claims.
