[0033] Please refer to Figures 1 to 3 The utility model relates to a garden tool, including a joystick 100, a working part 200 and a main body 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 body 300 is arranged at the rear of the joystick 100. The working part 200 includes a motor 210 and a cutting piece 220, wherein the motor 210 is accommodated in its housing, the housing is connected to the joystick 100, the motor 210 has an output end, and the cutting piece 220 is connected to the output end of the motor 210. The motor 210 drives the cutting piece 220 to operate on grass and lawns through the output end. The main body 300 includes a battery pack 330 and a housing 310 connected to the joystick 100, the battery pack 330 is used to supply power to the motor 210, and the power is converted into mechanical energy by the motor 210 and output to the cutting piece 220. The battery pack 330 is detachably connected to the housing 310 and can be electrically connected to the motor 210 via a cable received in the joystick 100. In addition, the host 300 may further include a control unit to control the operation of the motor 210.

[0034] The main machine 300 is arranged at the rear of the joystick 100, and is counterweighted with the working unit 200 located at the front of the joystick 100. The working unit 200 includes a heavy motor 210. To further improve the counterweight capability of the main machine 300, a counterweight block 320 is provided, and the counterweight block 320 is accommodated in the housing 310 of the main machine 300. The counterweight block 320 is located at the other end relative to the working unit 200, balancing the center of gravity of the whole machine, making it easy for users to use the garden tool and not easy to get tired when using it for a long time.

[0035] When the user uses the garden tool for operation, he / she holds the joystick 100 and the main unit 300 with his / her hands. Specifically, the joystick 100 is provided with a first gripping portion 110 for handholding, and the main unit 300 is provided with a second gripping portion 340 for handholding. The user can hold the first gripping portion 110 with one hand and the second gripping portion 340 with the other hand, so that the garden tool can maintain a certain operating angle for operation. In the front-to-back direction, the first gripping portion 110 is located between the working unit 200 and the second gripping portion 340. One operation method is: one hand holds the first gripping portion as a fulcrum, and the other hand holds and pushes the second gripping portion 340 to adjust the height of the working unit 200 at the other end.

[0036] In order to enhance the counterweight capability relative to the other end of the working part 200, the second gripping part 340 is located between the counterweight 320 and the first gripping part 110. The counterweight 320 is located in the housing 310 and is located at a position of the main unit 300 that is further away from the working part 200 relative to the second gripping part 340. Furthermore, the counterweight 320 is located between the battery pack 330 and the second gripping part 340. It should be noted that the battery pack 330 includes an installed state and a disassembled state. For a garden tool equipped with a battery pack 330, the counterweight 320 is located between the battery pack 330 and the second gripping part 340 at this time. After the battery pack 330 is installed, in the front-to-back direction, the counterweight 320 is located between the second gripping part 340 and at least part of the battery pack 330, which should also be considered as the counterweight 320 being located between the battery pack 330 and the second gripping part 340.

[0037] In order to fix the counterweight 320 and prevent it from loosening and damaging other components in the host 300 such as the control chip, the host 300 also includes a stopper 350 fixed in the shell 310, and the stopper 350 is used to fix the counterweight 320. Specifically, the stopper 350 has a hollow part, and the hollow part is substantially consistent with the shape of the counterweight 320. The counterweight 320 is embedded in the hollow part of the stopper 350 and fixed in the hollow part. Furthermore, the stopper 350 is provided with a plurality of convex ribs 351 on the wall surface of the inner hollow part, and the convex ribs 351 are used to clamp and fix the counterweight 320. When installing the counterweight 320, the counterweight 320 is pressed into the hollow part of the stopper 350, so that the counterweight 320 is pressed tightly by the plurality of convex ribs 351 around it, and the counterweight 320 is not easy to fall off from the stopper 350.

[0038] Furthermore, the counterweight 320 is cylindrical, and the stopper 350 is a circular groove adapted to the outer circumference of the counterweight 320. Of course, the stopper 350 can also be a combination of a pair of grooves in different embodiments. For example, the housing 310 of the host 300 is composed of a pair of semi-shells 310 combined with each other, and each semi-shell 310 is provided with a circular groove. When installing the counterweight 320, the counterweight 320 is first embedded in the groove on one of the semi-shells 310, and at least part of the counterweight 320 is exposed outside the groove; when the pair of semi-shells 310 are subsequently assembled, the exposed counterweight 320 is embedded in the groove on the other semi-shell.

[0039] The host 300 also includes a reinforcing rib 360 fixed to the inner wall of the shell 310, and the reinforcing rib 360 is used to strengthen the structural strength of the shell 310. Among them, the limiter 350 is connected and fixed to the reinforcing rib 360, so as to enhance the structural strength of the limiter 350 and prevent the limiter 350 from being affected by the weight of the counterweight 320 or shaking and causing damage. In order to further improve the structural strength of the limiter 350 and prevent the counterweight 320 from loosening, the reinforcing rib 360 has a plurality of reinforcing ribs, and the plurality of reinforcing ribs 360 are fixed to the limiter 350 in at least three different directions to enhance the strength of the limiter 350 in multiple force directions. In one embodiment, the limiter 350 is a circular groove, and the reinforcing rib 360 has three groups or three strips surrounding the outer circumference of the circular groove, and each group or each reinforcing rib 360 is at an angle of 120°.

[0040] In one 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.

[0041] 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.
