Description

Technical Field

[0001] This utility model relates to the field of cutting tools, and in particular to a cutting device for pruning branches, etc. Background Technology

[0002] Traditional garden pruning and shrub pruning cutting devices use a motor and reducer to drive the output shaft to rotate, which in turn drives the movable blade to move relative to the fixed blade for cutting.

[0003] However, in traditional cutting devices, the motor's axis is either coaxial with or parallel to the output shaft. This results in the motor occupying a large space in the height direction, requiring the housing to be correspondingly increased in height to accommodate the motor, thus increasing the overall thickness of the cutting device. To secure the motor within the housing, a fixing structure must be installed inside the housing to connect the motor. These fixing structures prevent the space within the housing around the motor from being used to accommodate batteries or other components, further contributing to the large overall size of the cutting device. Utility Model Content

[0005] The present invention employs a cutting device comprising a carrier assembly, a drive assembly, and a working assembly. The carrier assembly includes a handle and a drive device housing. The drive assembly includes a drive device and a drive output shaft coaxial with the drive device. The working assembly includes a fixed blade and a movable blade fitted to and movably connected to the fixed blade. The drive output shaft is driven by the movable blade, enabling the movable blade to move relative to the fixed blade and thus achieve cutting. The drive output shaft is rotatably connected to the carrier assembly, and the drive device is fixed within the carrier assembly.

Detailed Implementation

[0034] The specific embodiments of this utility model will now be described with reference to the accompanying drawings.

[0035] As a specific embodiment, the cutting device of this utility model includes a carrier component 1, a driving component 2, and a working component 3.

[0036] The carrier assembly 1 includes a handle portion 11 and a drive device receiving portion 12. For example, the carrier assembly 1 includes a left half shell 17 and a right half shell 18, which surround each other, and a handle shell 19 is fitted onto the tail of the left half shell 17 and the tail of the right half shell 18.

[0037] The drive assembly 2 includes a drive device 21 and a drive output shaft 22 coaxial with the drive device 21. It is easy to understand that the drive device 21 can be a motor and the drive output shaft 22 can be the motor shaft. Alternatively, the drive device 21 can be a motor connected to a speed change device 212 such as a planetary reducer and the drive output shaft 22 can be the output shaft of the speed change device 212.

[0038] The working component 3 includes a fixed blade 31 and a movable blade 32 that is fitted to and movably connected to the fixed blade 31 (through a blade connection structure 34); the drive output shaft 22 is driven to connect with the movable blade 32, allowing the movable blade 32 to move relative to the fixed blade 31 to achieve cutting. For example... Figure 5 As shown, the blade connection structure 34 is a rotating connection structure. The drive output shaft 22 drives the movable blade teeth 321 of the movable blade 32 to rotate relative to the fixed blade teeth 311 of the fixed blade 31, thus achieving a scissor-like cutting. At this time, the working component 3 is a scissor-type working component 38, which is typically used for cutting gardens; for example, Figure 8 As shown, the blade connection structure 34 is a linear sliding connection structure. The drive output shaft 22 drives the movable blade 32's movable teeth 321 to reciprocate linearly relative to the fixed blade 31's fixed teeth 311, achieving a saw-like cutting motion. In this case, the working component 3 is a saw-blade type working component 39, which is typically used for cutting shrubs. Of course, the movement of the movable blade 32 relative to the fixed blade 31 can also be other known movements in the prior art. It should be noted that the fixed blade 31 is only fixed relative to the movable blade 32; that is, the fixed blade 31 can also move relative to the carrier component 1.

[0039] The drive output shaft 22 is rotatably connected to the carrier assembly 1, for example, through a bearing; the drive device 21 is fixed inside the carrier assembly 1.

[0040] like Figure 4 As shown, both the drive device 21 and the drive output shaft 22 have portions located within the drive device receiving portion 12. That is, the drive device 21 can be entirely located within the drive device receiving portion 12, or a portion of the drive device 21 can be located within the drive device receiving portion 12 with the remaining portion located within the handle portion 11, etc. Furthermore, there is an angle of inclination 28, which is an acute angle, a right angle, or an obtuse angle, between the axis of the drive device 21 and the axis of the drive output shaft 22. In other words, there is an angle of inclination 28 between the axis of the drive device 21 and the axis of the drive output shaft 22 that is greater than zero degrees and less than 180 degrees. It is easy to understand that the angle of inclination 28 can be non-ninety degrees. The surface where the movable blade 32 and the fixed blade 31 are in contact is the cutting plane 33. The axis of the drive device 21 and the cutting plane 33 are also not perpendicular.

[0041] The working principle is that, compared with the existing technology in which the axis of the drive device 21 is perpendicular to the cutting plane 33, the space occupied by the drive device 21 in the height direction is reduced, thereby reducing the overall height of the cutting device; and the vibration generated by the drive device 21 during operation is not just a vibration in the horizontal plane, which can improve the ease of use of the cutting device to a certain extent.

[0042] As one specific embodiment, the surface where the movable blade 32 and the fixed blade 31 are in contact is the cutting plane 33. The drive device 21 has a portion located inside the handle portion 11, and there is an intersection point between the axis of the drive device 21 and the cutting plane 33, with this intersection point located outside the drive device receiving portion 12. Figure 4 As shown, there is an outer distance 29 between the intersection of the axis of the drive device 21 and the cutting plane 33 and the drive device housing 12. The outer distance 29 is a dimension greater than zero, so that there is an intersection between the axis of the drive device 21 and the cutting plane 33, and this intersection is located outside the drive device housing 12. This embodiment can reduce the overall height of the cutting device while also achieving the goal of not having to increase the length of the handle 11 too much.

[0043] As one specific implementation, the cutting device of this utility model embodiment also includes an electronic control device 8. The electronic control device 8 is a circuit board or the like used in the prior art for electronic control. The electronic control device 8 is electrically connected to an output device 82, which is a device such as a digital tube capable of outputting information emitted by the electronic control device 8. A receiving space 121 is formed between the top end of the inner cavity of the drive device receiving part 12 and the drive device 21. The output device 82 is fixed to the top end of the drive device receiving part 12 and has a portion located within the receiving space 121. This embodiment can reduce the overall height of the cutting device while facilitating the user's observation of the information emitted by the electronic control device 8. As a preferred arrangement, the cutting plane 33 is parallel to the bottom end surface of the drive device receiving part 12, and the axis of the drive output shaft 22 is perpendicular to the bottom end surface of the drive device receiving part 12, so that there is an acute or obtuse angle between the axis of the drive output shaft 22 and the cutting plane 33.

[0044] As one specific implementation, both the rotary output end 211 and the drive output shaft 22 are provided with bevel gears 221, and the bevel gears 221 mesh with each other, so that there is an acute or obtuse angle of inclination 28 between the axis of the drive device 21 and the axis of the drive output shaft 22. Usually, the bevel gears 221 are surrounded by a protective cover 223 to improve safety.

[0045] As one specific implementation, the cutting device of this utility model embodiment further includes an electronic control device 8 electrically connected to the driving device 21. The electronic control device 8 is electrically connected to an input device 81, which includes a start input device 811 and a lock input device (not shown in the figure). The start input device 811 and the lock input device can both be microswitches, or other devices that can send electrical signals to the electronic control device 8. The carrier component 1 is provided with a movable start trigger device 812 and a movable lock trigger device 814. For example, the start trigger device 812 and the lock trigger device 814 are linearly slidably connected to the carrier component 1. For example, the lock trigger device 814 is a linearly sliding button structure. The start trigger device 812 is directly opposite the start input device 811 and can be activated to trigger the start trigger device 812. The lock trigger device 814 is directly opposite the lock input device and can be activated to trigger the lock input device. The start-up trigger device 812 is located at the bottom of the handle portion 11, and the locking trigger device 814 is located on the side of the handle portion 11 or the drive device receiving portion 12, facilitating one-handed operation. It is easy to understand that the locking trigger device 814 can be located on one side of the drive device receiving portion 12, or multiple devices can be located on both sides of the drive device receiving portion 12, facilitating operation with either the left or right hand. By pressing or other means, the starting trigger device 812 simultaneously triggers the starting input device 811, and the locking trigger device 814 triggers the locking input device. The electronic control device 8 controls the drive device 21 to start and run. During the operation of the drive device 21, the locking trigger device 814 is reset (by a spring or the like), but the starting trigger device 812 remains in contact with the starting input device 811, and the drive device 21 continues to run. During the operation of the drive device 21, if the starting trigger device 812 is reset but the locking trigger device 814 is reset, or if the locking trigger device 814 remains in contact with the locking input device (i.e., the locking trigger device 814 is released), the drive device 21 stops. In other words, when the starting trigger device 812 is released, the drive device 21 stops regardless of the state of the locking trigger device 814. Compared to the mechanical safety structures used in existing technologies, this embodiment uses a smaller input device 81, such as a microswitch, to achieve safety control. Furthermore, both the starting trigger device 812 and the locking trigger device 814 do not require complex mechanical structures, thus reducing their size and saving space, thereby enabling miniaturization of the cutting device. The locking trigger device 814 is located on the side of the drive device 21 (i.e., in side view) and is exposed from the drive device housing 12. Because the drive device 21 is angled, there is sufficient space within the drive device housing 12 to accommodate the locking trigger device 814, thus eliminating the need to occupy the handle portion 11 or increase its size.

[0046] As one specific implementation, in the cutting device of this embodiment of the present invention, the electronic control device 8 is electrically connected to a power supply 83, which is disposed within the internal space of the carrier assembly 1. The power supply 83 can be a battery, a power connector, or a power cord, or other device capable of supplying power.

[0047] As one specific implementation, the working component 3 includes a working component carrier 35 fixedly connected to the fixed blade 31 and an insertable component 36. The drive output shaft 22 is fixedly connected to the insertable component 222. The insertable component 36 is provided with an insertable transmission tooth 3691, and the insertable component 222 is provided with an insertable transmission tooth 369. It is easy to understand that there can be at least one insertable transmission tooth 3691 and an insertable transmission tooth 369, as long as they can transmit rotational power. The working component carrier 35 is detachably connected to the drive device receiving part 12 so that the insertable transmission tooth 3691 of the insertable component 36 is inserted into the insertable transmission tooth 369 of the insertable component 222. For example, both the insertion drive teeth 369 of the inserted component 36 and the insertion drive teeth 369 of the inserted component 222 are arranged vertically. After the working component carrier 35 moves vertically relative to the drive device receiving portion 12 and connects with the drive device receiving portion 12, the insertion drive teeth 369 of the inserted component 36 and the insertion drive teeth 369 of the inserted component 222 are inserted into each other. The inserted component 222 can rotate with the drive output shaft 22, thereby rotating the inserted component 36. As mentioned above, this embodiment allows for convenient replacement of different specifications or functions of the working components 3, such as the scissor-type working component 38 and the saw blade-type working component 39, as needed. It should be noted that the insertion order of the inserted component 222 and the inserted component 36 is not limited; that is, it is not limited to inserting the inserted component 222 into the inserted component 36, but the inserted component 36 can also be inserted into the inserted component 222.

[0048] As one specific implementation, the working component carrier 35 is provided with a mounting buckle 351 and a mounting elastic member 353. The mounting buckle 351 includes a mounting buckle 352, and the drive device receiving portion 12 is provided with a latched portion 125. For example, the latched portion 125 is provided on the bottom end surface of the drive device receiving portion 12. The mounting elastic member 353 is connected to the working component carrier 35 and the mounting buckle 351 respectively, so that the mounting buckle 352 tends to approach the latched portion 125, thereby making the working component carrier 35 and the drive device receiving portion 12 detachably connected. Pressing the mounting buckle 352 allows the mounting buckle 352 to be misaligned with the latched part 125, which facilitates the separation of the working component carrier 35 from the drive device receiving part 12. After the mounting buckle 352 abuts against the latched part 125, the working component carrier 35 is connected to the drive device receiving part 12. At this time, the mounting elastic element 353 can ensure the stability of the connection between the working component carrier 35 and the drive device receiving part 12. In summary, the working component 3 can be easily disassembled and installed.

[0049] As one specific implementation, the bottom end face of the inserted member 36 is provided with an eccentric body 23, and the movable blade 32 includes a driven end 322 with an eccentric body groove 323. The eccentric body 23 is inserted into the eccentric body groove 323 to drive the movable blade 32 to move. It is easy to understand that there is a point on the eccentric body 23, and the distance from this point to the rotation axis of the inserted member 36 changes with the rotation of the inserted member 36. For example, the eccentric body 23 is cylindrical, and there is a gap between the axis of the cylinder and the rotation axis of the inserted member 36. The cross-section of the eccentric body groove 323 is racetrack-shaped (the two ends of the rectangle are respectively spliced ​​with semicircles aligned with the two ends), and the eccentric body 23 is inserted into the eccentric body groove 323 in a close fit. This implementation can ensure that the eccentric body 23 drives the movable blade 32 to move relatively stably, and will not generate vibration and noise due to the eccentric body 23 hitting the inner wall of the eccentric body groove 323.

[0050] As one specific implementation, the driven end 322 is provided with a height limiting edge 324, and the inserted component 36 is provided with an inserted component flange 361; the inserted component 36 passes through the top cover (not shown in the attached drawings) of the working component carrier 35 and is movably connected to the working component carrier 35, for example, through a rotatable connection; the height limiting edge 324 and the top cover of the working component carrier 35 respectively abut against the inserted component flange 361, or the height limiting edge 324 and the top cover of the working component carrier 35 respectively approach the inserted component flange 361; and as Figure 7 As shown, during the rotation of the inserted component 36, when viewed from above, the flange 361 of the inserted component always overlaps with the height limiting edge 324. For example, the flange 361 of the inserted component is a disk shape coaxial with the inserted component 36, and the diameter of this disk shape is sufficiently large so that when viewed from above, the flange 361 of the inserted component always overlaps with the height limiting edge 324 during the rotation of the inserted component 36. In this embodiment, the rotatable connection between the inserted component 36 and the working component carrier 35 can be achieved without bearings or other components. In addition, when assembling the working component 3, it is only necessary to place the flange 361 of the inserted component on the height limiting edge 324, and then install and fix the top cover of the working component carrier 35, which facilitates the assembly of the working component 3.

[0051] The terms used in this invention, such as "first," "second," etc., do not indicate any order, quantity, or importance, but are merely for distinction.

[0052] In this invention, terms such as "a" or "an" are used to indicate not a limitation on the quantity, but rather to indicate the existence of at least one of the mentioned objects.

[0053] In this utility model, terms indicating direction or location such as top, bottom, side, longitudinal, transverse, middle, center, outside, inside, horizontal, vertical, left, right, above, and below are used to indicate relative positions rather than absolute positions.

[0054] Terms used in this invention, such as "approximately," "generally," "approximately," and "similar," are limiting terms used to indicate features that are present but allow for certain deviations. The amount of deviation allowed may vary depending on the specific context; for example, regarding dimensional deviations, the specific context may include, but is not limited to, relevant standards for dimensional tolerances.
