Description

Technical Field

[0001] This utility model relates to the field of garden tool technology, and in particular to an extended structure for a garden tool. Background Technology

[0002] Hand shears are a common type of handheld electric garden tool. For example, CN215920544U discloses a novel type of hand shears with a specific cutting method, comprising a motor assembly, a transmission mechanism, and a blade assembly. The blade assembly includes a moving blade and a fixed blade, and the cutting motion is achieved through the linear reciprocating motion of the moving and fixed blades and the coordinated design of a gear assembly. This hand shear has a relatively narrow range of applications. To broaden its usability, an extension structure, such as an extended handle, needs to be added to the hand shears to increase its usability. Therefore, an extension structure is needed to meet market demand. Utility Model Content

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0030] The terminology used herein is intended to explain the embodiments and is not intended to limit and / or restrict the present invention.

[0031] Example 1

[0032] like Figures 1-3As shown, the tool body 10 in this embodiment is a palm-shaped scissor structure. A safety switch 11, a control switch 12, and a first power connection module 13 are provided on the tool body 10. The safety switch 11 and the control switch 12 are located on the upper and lower sides of the tool body 10, respectively. The first power connection module 13 is located on the left and right sides of the tool body 10. A power supply unit 50 can be plugged into the first power connection module 13. The power supply unit 50 has a battery pack to provide power to the tool body 10. When the safety switch 11 is open, turning on the control switch 12 will enable the cutting function of the tool body 10.

[0033] Combination Figures 4-7 As shown, the corresponding extension structure is used to be detachably installed to the tool body 10, and mainly includes a first adapter module 20 disposed on the tool body 10, a second adapter module 30 disposed on the tool body 10, and an extension module 40 rotatably connected to the first adapter module 20.

[0034] The first adapter module 20 contacts the safety switch 11 and keeps the safety switch 11 in the open state. The first adapter module 20 has a space to accommodate part of the tool body 10. The first adapter module 20 includes a first outer shell 21. A second power connection module 22 and a third power connection module 23 are respectively provided on the inner and outer sides of one end of the first outer shell 21. The first power connection module 23 is plugged into the second power connection module 22 or the power supply unit 50. The third power connection module 23 is plugged into the power supply unit 50. The first power connection module 23, the second power connection module 22, the third power connection module 23, and the power supply unit 50 are electrically connected.

[0035] Furthermore, a contact member 24 is provided inside the first outer casing 21. The contact member 24 is used to abut against the safety switch 11. The contact member 24 is rotatably connected to the first outer casing 21. A limiting plate 25 is also provided inside the first outer casing 21. The limiting plate 25 is used to prevent the contact member 24 from disengaging from the safety switch 11. That is, a shaft is provided inside the first outer casing 21. The contact member 24 is rotatably sleeved on the shaft. A certain part of the shaft protrudes outward to form a plate-like structure, which can abut against the safety switch 11 to keep the safety switch 11 in the open state. The limiting plate 25 is inclined towards the contact member 24 to form a plate-like structure, which can contact the contact member 24 and prevent the contact member 24 from disengaging from the safety switch 11 after reversing.

[0036] Additionally, an adapter 26 is provided at the upper end of the first outer shell 21, and the adapter 26 is rotatably connected to the extension module 40.

[0037] The second adapter module 30 contacts the control switch 12 and keeps the control switch 12 in the open state. The second adapter module 30 has a space to accommodate part of the tool body 10. The first adapter module 20 is rotatably connected to one side of the second adapter module 30, and the other side of the first adapter module 20 and the second adapter module 30 are detachably connected.

[0038] Furthermore, the second adapter module 30 includes a second housing 31, within which an elastic body 32 and a second contact member 33 are disposed. The elastic body 32 is a spring that provides elastic force to abut the second contact member 33 against the control switch 12. The two sides of the second housing 31 extend outward to form adapter arms 34, generally forming a U-shaped structure. One adapter arm 34 is rotatably connected to one side of the first housing 21 via a pivot, while the other adapter arm 34 is detachably connected to the other side of the first housing 21.

[0039] The structure of the elastomer 32 ensures that even if vibration occurs during use, the contact 33 and the control switch 12 can still make contact.

[0040] Here, a connector 211 is provided on the other side of the first outer shell 21, and the end of the other adapter arm 34 is folded inward to form a connector 341. The connector 211 and the connector 341 are engaged and cooperated, that is, the two generally form an L-shaped docking structure.

[0041] The extension module 40 is equipped with a second safety switch 41 and a second control switch 42. The second control switch 42 and the first control switch 12 are connected in series via a circuit board. The extension module 40 has a handle structure for easy gripping and use, thereby increasing its usability. Similarly, the tool body 10 can only work when the second safety switch 41 is turned on and the second control switch 42 is turned on. The extension module 40 and the first adapter module 20 have built-in wires that are connected to the power supply position. When the extension structure is installed, the second control switch 42 and the first control switch 12 must be turned on simultaneously to enable the tool body 10 to work.
