In the present invention, multiple groups of connecting assemblies 33 are arranged at the same time, and each group of connecting assemblies 33 includes a connecting base 331 directly / indirectly connected to the panel 12 and a locking member 332 that penetrates the outer shell 13 and is clamped and connected to the outer shell 13. The locking member 332 is threadedly connected to the connecting base 331 to lock the panel 12 and the outer shell 13.

[0032] In a preferred embodiment of the present invention, a connecting column 14 (such as Figure 3 ), the connecting base 331 is connected to the end of the connecting column 14, and is connected to the panel 12 through the connecting column 14, so as to realize the locking connection between the panel 12 and the outer shell 13 through the cooperation with the locking member 332, and at the same time limit the connection distance between the panel 12 and the outer shell 13, so as to facilitate the heat dissipation and use of the garden tool 100.

[0033] The locking member 332 penetrates the outer shell 13 and is clamped on the outer shell 13, and can rotate relative to the outer shell 13 to facilitate the locking connection between the locking member 332 and the connecting base 331. Furthermore, a rotating member 333 is also provided on the surface of the locking member 332. In the present invention, the rotating member 333 is provided in a groove or a protrusion shape to facilitate the user to drive the locking member 332 to rotate through the cooperation of the key structure 34 and the rotating member 333 to achieve the locking connection with the connecting base 331.

[0034] The key structure 34 is inserted into the receiving slot 311 and can be switched between a start position and an off position. When the key structure 34 is rotated to the start position, the magnetic switch 32 can be controlled to be in an on state, and the power supply component and the drive component can be further controlled to be powered on, so that the garden tool 100 can be used to perform corresponding garden work tasks.

[0035] In the present invention, the key assembly 34 includes a twist handle 341 and a plug-in portion 342 connected to one end of the twist handle 341. The twist handle 341 is used to drive the plug-in portion 342 to switch between a start position and a shut-off position.

[0036] On one hand, the plug-in portion 342 can be inserted into the receiving groove 311 to trigger the magnetic switch to realize the shut-off control of the garden tool 100 , and on the other hand, it can also be used to realize the connection or removal of the connection assembly 32 .

[0037] In the present invention, a locking member 343 and an unlocking member 344 are provided at one end of the plug-in portion 342 away from the twist handle 341, and along the plug-in direction of the plug-in portion 341 and the garden tool 100, the locking member 343 is located at the end of the plug-in portion 341, and the unlocking member 344 and the locking member 343 are staggered front and back.

[0038] Specifically, the locking member 343 is used to complete the disassembly / fastening of the connecting component 33, and in the present invention, the locking member 343 is a groove or a protrusion that can be engaged with the rotating member 333. Such a configuration allows the key structure 34 to be connected to the connecting component 33 through the locking member 343, and the locking of the connecting component 33 can be further completed by rotating the key structure 34.

[0039] Along the plugging direction of the plug-in portion 342, the plug-in portion 342 is further provided with a receiving portion 345 located above the locking member 343, and the unlocking member 344 is received in the receiving portion 345, and the extension direction of the unlocking member 344 is perpendicular to the extension direction of the plug-in portion 342. Preferably, the unlocking member 34 is a magnetic unlocking member with magnetism, and the N pole and S pole of the magnetic unlocking member are respectively located on both sides of the extension direction of the unlocking member 34, and the center line of the magnetic switch 32 is located on the same straight line as the center line of the magnetic unlocking member. With this arrangement, while ensuring that the unlocking member 344 has a smaller volume, the magnetic pole of the unlocking member 344 is set closer to the magnetic switch 32, thereby ensuring the unlocking effect of the safety key assembly 3.

[0040] In a preferred embodiment of the present invention, a baffle 346 is provided between the twist handle 341 and the plug-in portion 342. When the safety key assembly 3 of the present invention is used, the baffle 346 can abut against the edge of the housing 31 / the receiving groove 311 to prevent the plug-in portion 342 from excessively extending into the receiving groove 311 and causing damage to the safety key assembly 3 or the panel 12, thereby ensuring the service life of the garden tool 100.

[0041] Furthermore, a pointing structure 347 is provided on the surface of the baffle 346, and a pointing mark (not shown) corresponding to the pointing structure 347 is provided on the panel 12. When and only when the pointing structure 347 points to the pointing mark, the plug-in portion 342 can be plugged into the receiving groove 311 along the plug-in direction, and at this time the key structure 34 is in the off position.

[0042] It should be noted that the key structure 34 in the present invention may also have a conventional structure of a mechanical key in the prior art, and the structure of the security key assembly 3 in this specification is only exemplary and should not be limited thereto.

[0043] Furthermore, in the specific embodiment of the present invention, only the shell 31 and the panel 12 of the safety key assembly 3 are set as an integral part for illustration. In other embodiments of the present invention, the shell 31 and the panel 12 can also be set separately. In this case, the safety key assembly 3 can also be set at a position such as the handle of the garden tool 100. It is only necessary to ensure that the electrical connection between the magnetic switch 32 and the drive assembly is stable.

[0044] Specifically, when using the garden tool 100 of the present invention, first, the key structure 34 is inserted into the receiving groove 311 provided on the panel 12 according to the directional mark 347. At this time, the key structure 34 is in the off position and the magnetic switch 32 is in the off state; further, the plug-in portion 342 is rotated by twisting the handle 341 to rotate the key structure 34 to the starting position. At this time, the unlocking member 344 acts on the magnetic switch 32, so that the magnetic switch 32 is in the closed state, and the driving component and the power supply component are further controlled to be powered on. The user can control the garden tool 100 through the control component 121 to achieve the corresponding garden work tasks.

[0045] Furthermore, when it is necessary to disassemble / tighten the shell assembly 1 of the garden tool 100, the key structure 34 must first be rotated from the start position to the off position to control the drive assembly and the power supply assembly to be powered off, and the key structure 34 must be taken out from the receiving groove 311. At this time, the user can disassemble / tighten the connecting assembly 33 through the locking member 343 provided at the end of the key structure 34 to achieve the disassembly and assembly of the shell assembly 1. At this time, since the key structure 34 has been removed from the receiving groove 311, the garden tool 100 is in a powered-off state, which avoids the user from accidentally touching the charged drive assembly / power supply assembly when disassembling the shell assembly 1 and causing electric shock, thereby effectively improving the safety of the garden tool 100.

[0046] In summary, the safety key assembly 3 of the present invention can be used to control the start and stop of the driving assembly of the garden tool 100 by simultaneously arranging the locking member 343 and the unlocking member 345 in the key structure 34, so that the safety key assembly 3 of the present invention can be used to control the start and stop of the driving assembly of the garden tool 100; it can also be used to connect or release the housing assembly 1 of the garden tool 100, which effectively improves the practicality of the safety key assembly 3, and at the same time makes the garden tool 100 using the safety key assembly 3 have good practicality and good safety in use.
