Detailed Implementation

[0021] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0022] like Figures 1-8 As shown, a detachable blade head structure includes a handle 1 and a blade head 2. The bottom of the blade head 2 is provided with a plug-in portion 21 and at least two connecting portions 22, and a buckle 221 is provided on one side of the bottom of the connecting portion 22. The handle 1 includes a housing, a limiting plate 3 and a drive source 4 disposed within the housing, and the plug-in portion 21 can be connected to the drive source 4.

[0023] Meanwhile, the limiting plate 3 is movable and adapts to the elastic element 5, and a pressing part 31 is provided on one side of the limiting plate 3, which protrudes through the housing. In addition, the limiting plate 3 has a snap-fit ​​hole 32 corresponding to the connecting part 22, and the housing has a through hole 11 corresponding to the snap-fit ​​hole 32.

[0024] Therefore, in actual use, the connection part 22 passes through the through hole 11 and the snap-fit ​​hole 32, and the buckle 221 abuts against the bottom of the limiting plate 3 to achieve the limiting. At this time, the insertion part 21 is connected to the drive source 4, and the buckle 221 and the limiting plate 3 are separated by pressing the pressing part 31, thereby separating the handle 1 and the blade 2.

[0025] Therefore, this utility model has multiple connection points, which can ensure the stability of the connection. The connection part 22 is separated by pressing the pressing part 31 to separate the handle 1 and the blade head 2.

[0026] Furthermore, the drive source 4 can be a motor, and the elastic element 5 can be a spring. Additionally, a cover 10 can be provided on the cutter head 2 to protect the components at the top of the cutter head 2.

[0027] like Figure 4 As shown, the bottom of the cutter head 2 is provided with a placement groove 23, and the bottom surface of the placement groove 23 is provided with a connecting part 22. The bottom surface of the placement groove 23 is provided with an opening 231 for the insertion part 21 to pass through. The inner side of the placement groove 23 is provided with a protrusion 232. The top of the housing is provided with a mounting part, and the limiting plate 3 is located in the mounting part. The top of the mounting part is provided with a through hole 11. The mounting part is located in the placement groove 23 and a groove rail 12 is provided corresponding to the protrusion 232.

[0028] Therefore, in actual use, when the cutter head 2 is placed on the handle 1 and moves, the convex strip 232 and the groove rail 12 are matched to guide and limit the movement.

[0029] like Figures 2-6 As shown, the housing includes a top shell 13 and a bottom shell 14, and a cover 15 located on the top shell 13. The cover 15 is a mounting part and has a through hole 11. The top shell 13 is provided with a boss 131. The limiting plate 3 is located between the top shell 13 and the cover 15, and the limiting plate 3 has a hole 33 corresponding to the boss 131.

[0030] Meanwhile, the bottom of the limiting plate 3 is provided with a connecting part 2 34, and a pressing part 31 is provided on the side of the connecting part 2 34 away from the boss 131, and an elastic member 1 5 is provided between the connecting part 2 34 and the boss 131.

[0031] Therefore, in actual use, the limiting plate 3 is separately equipped with a cover 15 and is not directly between the top shell 13 and the bottom shell 14, so it will not affect the structure between the top shell 13 and the bottom shell 14. Moreover, a post 341 is provided on one side of the connecting part 2 34 near the boss 131, and the elastic element 1 5 is sleeved on the outside of the post 341 to realize the installation of the elastic element 1 5.

[0032] Secondly, a drive source 4 is provided between the top shell 13 and the bottom shell 14, and a gear 61 is provided between the top shell 13 and the cover 15. The drive source 4 is connected to the gear 61, and the cover 15 has an exposure port 151 for exposing the gear 61, and the insertion part 21 is connected to the gear 61.

[0033] Therefore, in actual use, the drive source 4 drives the gear 61 to rotate and transmits the power to the cutter head 2 through the plug part 21. Moreover, the structure between the drive source 4 and the gear 61 is such that the drive shaft of the drive source 4 is connected to the gear 62, and the gear 62 meshes with the gear 61. Screws can be used between the top shell 13 and the bottom shell 14, and a decorative shell 16 is also provided at the bottom of the bottom shell 14.

[0034] Meanwhile, the cover 15 covers the outside of the boss 131 and is connected to the boss 131 by screws. The inner side wall of the cover 15 is provided with a protrusion 152, and the outer side wall of the boss 131 is provided with a groove 132 corresponding to the protrusion 152.

[0035] Therefore, in actual use, the connection between the cover 15 and the top shell 13 is achieved by matching the protruding strip 152 and the groove rail 132 and connecting them with screws.

[0036] like Figure 3As shown, the inner wall of the snap-fit ​​hole 32 is formed with a first inclined surface 321, and the bottom of the buckle 221 is formed with a second inclined surface 222, and the second inclined surface 222 and the first inclined surface 321 are adapted to each other. Therefore, in actual use, since the second inclined surface 222 and the first inclined surface 321 are adapted to each other, they play a guiding role, that is, they drive the buckle 221 into the snap-fit ​​hole 32.

[0037] like Figures 1-3 and Figures 7-8 As shown, the cutter head 2 includes a first blade assembly 20 and at least two second blade assemblies 30, and the first blade assembly 20 includes a second elastic element. The cutter head 2 also includes a base 24, an upper shell 25, and an outer shell 26. The base 24 is connected to the handle 1, and the base 24 is provided with a second insertion part and a third insertion part 241 corresponding to the first blade assembly 20 and the second blade assembly 30, respectively. The first insertion part 21 is connected to the second insertion part and the third insertion part 241 via a gear set.

[0038] Meanwhile, the upper shell 25 is disposed on the base 24, and the mounting platform 251 is disposed in the middle of the upper shell 25. The blade assembly 20 is disposed on the mounting platform 251, and the outer shell 26 is located outside the mounting platform 251 and rotatably disposed on the upper shell 25. The two blade assemblies 30 are a group and disposed on the outer shell 26. An elastic member 8 is disposed between the outer shell 26 and the upper shell 25.

[0039] Therefore, in actual use, except for the central blade assembly 20, the blade assemblies 30 are grouped in pairs. That is, the housing 26 and the elastic element 3 8 are used for two blade assemblies 30. Compared with each blade assembly 30 being paired with a separate housing 26 and elastic element 3 8, grouping them in pairs simplifies the structure and reduces costs. The rotating structure of the housing 26, which is rotatably mounted on the upper housing 25, is a shaft hole structure. That is, the upper housing 25 has a rotating shaft 252 on the side near the housing 26, and the housing 26 has a corresponding opening. The elastic elements 2 and 3 8 are springs.

[0040] Furthermore, the blade assembly 20 and the blade assembly 20 are basically existing technologies, namely including a blade and a holder with holes. Since they are not the focus of this utility model, they will not be described in detail. Also, the bottom of the outer casing 26 is located inside the top of the base 24 between the outer casing 26 and the base 24.

[0041] Secondly, the structure of the base 24 is as follows: The base 24 includes a lower shell 242, a mounting shell 243 and a connecting shell 244. The lower shell 242 is connected to the handle 1, and the lower shell 242 has an opening 231 for the insertion part 21 to pass through.

[0042] Meanwhile, the mounting shell 243 is disposed on the lower shell 242, and the upper shell 25 is disposed on the connecting shell 244. A gear set is disposed between the mounting shell 243 and the connecting shell 244. The gear set includes a main gear 91, a driven gear 92 and a transmission gear 93. The main gear 91 is used to connect the first insertion part 21 and the second insertion part. The two sides of the transmission gear 93 are respectively meshed with the main gear 91 and the two driven gears 92. The driven gears 92 are connected to the third insertion part 241.

[0043] Therefore, in actual use, when the drive source 4 transmits power to the insertion part 21, it will drive the main gear 91 to rotate, thereby driving the transmission gear 93 and the insertion part 2, and then driving the blade of the blade assembly 20. Moreover, the rotation of the transmission gear 93 will drive the driven gear 92, thereby driving the insertion part 241 and driving the blade of the blade assembly 20. Furthermore, the lower shell 242, the mounting shell 243, and the connecting shell 244 are connected by screws.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. However, this utility model is not limited to the above embodiments; therefore, various changes and modifications can be made without departing from the principles and scope of this utility model, and all such changes and modifications fall within the scope of the claimed utility model.
