Description

Technical Field

[0001] The present application relates to the technical field of garden tools. Background Art

[0002] Long-pole garden tools such as brush cutters have a long joystick and are convenient for carrying out specific garden operations. However, during the interval between operations, the long-pole garden tools tend to take up a large space due to their slender shape, making it quite inconvenient to store them accordingly.

[0037] Please refer to Figures 1 to 4 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 wire 400 stored inside the joystick 100. In addition, the host 300 can further include a control unit to control the operation of the motor 220.

[0038] In order to facilitate the storage of garden tools, the joystick 100 can be bent. The joystick 100 includes a straight main rod body 110 and a bending portion 120 located in the middle of the main rod body 110, and the bending portion 120 is approximately located in the center of the main rod body 110. The main rod body 110 is an elongated cylindrical body and is the main structure of the joystick 100. The bending portion 120 is a part of the joystick 100 that is specifically bent. The bending portion 120 can be a deformable or breakable part of the joystick 100, so that the joystick 100 as a whole has the ability to be bent. Specifically, the bending portion 120 includes a straight state and a bent state. In the bent state, a part of the wire 400 will be exposed outside the joystick 100, and the exposed part is located at the bending portion 120; in the straight state, the wire 400 is completely stored inside the joystick 100, including being stored in the main rod body 110 and the bending portion 120. The part of the wire 400 exposed outside the joystick 100 is set to be spring-shaped. Of course, more or all of the wires 400 can also be set to be spring-shaped. When the spring-shaped wire 400 is bent with the bending portion 120, the wire 400 can remain in a relatively relaxed state and will not be damaged due to excessive tension. The spring-shaped wire 400 will not be damaged due to fatigue after multiple bending operations.

[0039] In order to protect the exposed wire 400 and prevent the stored garden tool from being damaged and unusable, the wire 400 is wrapped with a sheath 410, and the sheath 410 at least wraps around the exposed portion of the wire 400. Further, in order to improve the protective effect of the sheath 410 on the wire, the sheath 410 is an insulating sheath, such as a rubber sheath or a plastic sheath.

[0040] In one embodiment, the spring-shaped wire 400 is wrapped with a corresponding spring-shaped sheath 410. The sheath 410 is tightly wrapped around the spring-shaped wire 400, so that the sheath 410 itself is also spring-shaped. The spring-shaped sheath 410 has similar anti-bending and anti-stretching properties as the spring-shaped wire 400, and is not prone to cracks or breaks due to frequent bending or stretching, so that the sheath 410 can more effectively protect the internal wire 400.

[0041] To further enhance the protection effect of the wire 400, straight wires 400 are distributed on both sides of the spring-shaped partial wire 400, and the sheath 410 partially wraps the above-mentioned straight wire 400 on both sides of the spring-shaped sheath 410. The sheath 410 completely wraps and protects the spring-shaped wire 400, and the sheath 410 extends to wrap and protect the straight wires 400 extending from the two wings of the spring-shaped wire 400.

[0042] It should be noted that the wire 400 in the present application is not limited to whether it includes an insulating layer, that is, it can be a bare wire without an insulating layer or a non-bare wire including an insulating layer.

[0043] In one embodiment, the main rod body 110 can be divided into a first straight rod portion 111 and a second straight rod portion 112. Specifically, the main rod body 110 is divided into a first straight rod portion 111 connected to the working part 200 and a second straight rod portion 112 connected to the main machine 300 by the bending portion 120, and the first straight rod portion 111 and the second straight rod portion 112 are respectively located on both sides of the bending portion 120. One end of the first straight rod portion 111 is connected to the working part 200, and the other end is connected to the bending portion 120; one end of the second straight rod portion 112 is connected to the main machine 300, and the other end is connected to the bending portion 120. In this embodiment, when the bending portion 120 is in a straight state, the axis of the first straight rod portion 111 is collinear with the axis of the second straight rod portion 112; when the bending portion 120 is in a bent state, the axis of the first straight rod portion 111 intersects or is parallel to the axis of the second straight rod portion 112. For example, before the storage action of the garden tool begins, the bending portion 120 is in a straight state, the joystick 100 is straight as a whole, and the axis of the first straight rod portion 111 and the axis of the second straight rod portion 112 are collinear; after the storage action of the garden tool begins, the bending portion 120 is in a bent state, the axis of the first straight rod portion 111 and the axis of the second straight rod portion 112 begin to intersect, and the joystick 100 is in a bent state as a whole; after the storage action of the garden tool is completed, the axis of the first straight rod portion 111 and the axis of the second straight rod portion 112 are parallel, the first straight rod portion 111 and the second straight rod portion 112 are stacked on each other, and the joystick 100 enters a state of occupying less space with a smaller total length.

[0044] In one embodiment, the bending portion 120 includes a first rotating connection member 121 and a second rotating connection member 122, wherein the first rotating connection member 121 is fixed to the end of the first straight rod portion 111, and the second rotating connection member 122 is fixed to the end of the second straight rod portion 112. The first rotating connection member 121 and the second rotating connection member 122 are hinged, and the first straight rod portion 111 and the second straight rod portion 112 are hinged to each other, so that the first straight rod portion 111 and the second straight rod portion 112 are rotatably connected, and the first straight rod portion 111 and the second straight rod portion 112 will not be completely separated from each other. Compared with completely disassembling the joystick 100 for storage, the storage and reuse of the garden tool is more convenient.

[0045] In order to further facilitate the bending of the bending portion 120, the first rotating member connecting member and the second rotating member 122 are further connected by an unlockable locking member (not shown in the figure). After the locking member is unlocked, the first rotating member can rotate relative to the second rotating member around the hinge end 123, and before the locking member is unlocked, the first rotating member is locked with the second rotating member. Preferably, the locking member is a latch.

[0046] 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 mower, an edge trimmer, etc.

[0047] 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.
