[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0031] Please refer to Figure 1 and Figure 2 This embodiment provides a multi-functional cutting tool, including a handle 1, a blade 2, and a burr removal assembly 3. The blade 2 includes, along its length, a mounting section 21, a cutting edge section 22, and a connecting section 23. The mounting section 21 is detachably mounted to the handle 1. The burr removal assembly 3 is disposed on the connecting section 23 and includes a sleeve 31 and a brush 32. The sleeve 31 is detachably connected to the connecting section 23 via a snap-fit ​​mechanism 4 and can move axially along the blade 2 to selectively fix it to either the handle 1 or the connecting section 23. The brush 32 is disposed on the outer periphery of the sleeve 31. The mounting section 21 on the blade 2 can be fixed to the handle 1 by a spindle clamp. The mounting section 21, the cutting edge section 22, and the connecting section 23 are integrally formed, and their maximum diameters are the same, thus facilitating the sliding of the sleeve 31 along the blade 2.

[0032] The tool of the embodiment integrates cutting and burr removing functions, and the user can select according to actual needs, such as using the tool body 2 with the blade section 22 to perform forming processing on the circuit board, and then using the burr removing assembly 3 with the brush 32 to perform metal chip removing processing on the circuit board, so that the forming and metal chip removing processing of the circuit board can be quickly completed without using additional tools, which improves the convenience of use and the processing efficiency of the circuit board. In addition, the burr removing assembly 3 is connected with the tool body 2 through the clamping mechanism 4 and can move in the axial direction, and the user can fix it on the tool handle 1 or the connecting section 23 according to actual needs to adapt to different working scenes.

[0033] Please refer to Figure 1 , Figure 2 and Figure 3 In the embodiment, the clamping mechanism 4 includes a protrusion 41 provided on the connecting section 23, at least one clamping groove 42 provided on the protrusion 41, and at least one clamping block 43 provided on the inner side wall of the sleeve 31. The protrusion 41 extends outward along the radial direction of the connecting section 23, and the clamping block 43 is matched with and can be clamped with the clamping groove 42. Specifically, the protrusion 41 can be provided at the bottom of the connecting section 23 and has a cylindrical structure. The clamping block 43 and the clamping groove 42 are both provided in four, and the four clamping grooves 42 are arranged at intervals of 90 degrees, and the four clamping blocks 43 are arranged at the top of the inner side wall of the sleeve 31. The clamping block 43 and the clamping groove 42 can be installed in an interference fit, and the interference amount is 0.1-0.2mm.

[0034] By clamping the clamping block 43 in the clamping groove 42, the assembly between the sleeve 31 and the connecting section 23 can be quickly completed, so that the sleeve 31 is fixed relative to the tool body 2, so that the tool body 2 can drive the rotation of the sleeve 31 when rotating to achieve the metal chip removing operation. At the same time, it is also convenient to disassemble the sleeve 31, without the need for complex tools or additional operation steps, greatly improving the efficiency of installation and disassembly.

[0035] Of course, as other embodiments, the sleeve 31 and the connecting section 23 can be connected in a threaded connection manner. That is, an external thread is provided on the outer surface of the connecting section 23, and an internal thread is provided on the inner side wall of the sleeve 31, and the sleeve 31 is screwed with the connecting section 23 by rotating. Although it needs to be rotated several times to be fixed or disassembled, it is stable and not easy to loosen, and the position of the sleeve 31 can be adjusted by rotation.

[0036] In addition, the connection between the sleeve 31 and the connecting section 23 can also be achieved by spring ball positioning. A plurality of grooves or hole positions are provided on the connecting section 23, and spring balls, i.e. spring-loaded balls, are installed on the inner side wall of the sleeve 31. When the sleeve 31 moves to a specific position, the spring balls will pop into the grooves to achieve fixation.

[0037] Please refer to Figure 1 andFigure 4 In the present embodiment, the end of the shank 1 is provided with a mounting groove 11 matching the outer contour of the sleeve 31, when the sleeve 31 is moved along the blade body 2 to the shank 1, the sleeve 31 can be partially embedded in the mounting groove 11 and fixed by friction. And the end of the sleeve 31 close to the shank 1 is provided with a beveled part 311, which can be clamped in the mounting groove 11.

[0038] Due to the precise matching of the mounting groove 11 and the outer contour of the sleeve 31, when the sleeve 31 is moved to the position of the shank 1 and embedded in the mounting groove 11, the precise positioning between the sleeve 31 and the shank 1 can be ensured, avoiding the problem of unstable operation or low efficiency caused by positional deviation, and at this time the shank 1 can drive the rotation of the sleeve 31 to realize the cleaning operation of metal chips. Therefore, the user can flexibly choose to install the sleeve 31 on the connecting section 23 or the shank 1 according to the actual use scene, and the two installation modes can be quickly switched, and the use is flexible.

[0039] Among them, the design of the beveled part 311 makes the sleeve 31 gradually produce a radial expansion force during embedding in the mounting groove 11, when the beveled part 311 is completely clamped into the mounting groove 11, this expansion force is converted into locking force, which enhances the connection strength between the sleeve 31 and the shank 1, and ensures more reliable locking effect. In addition, the beveled part 311 not only plays a locking role, but also plays a role of installation guide. During the movement of the sleeve 31 along the blade body 2 to the shank 1, the beveled part 311 can smoothly guide the sleeve 31 into the mounting groove 11, reducing the resistance during installation, making the operation more smooth.

[0040] In the present embodiment, the brush 32 includes continuous bristles, which are helically distributed along the length direction of the sleeve 31. The included angle between the helical center line of the bristles and the axis of the sleeve 31 is 40 degrees to 50 degrees.

[0041] The design of the helical distribution of the bristles along the length direction of the sleeve 31 makes the bristles more fully contact the surface to be cleaned when the sleeve 31 rotates or moves, thereby enhancing the cleaning effect. And the helically distributed bristles can bear force uniformly during cleaning, avoiding the problem of local excessive wear, prolonging the service life of the brush 32, and maintaining stable cleaning performance.

[0042] The design of the included angle of 40 degrees to 50 degrees makes the bristles cover a wider area during rotation, reduces the blind area during cleaning, and can ensure that the bristles contact the surface to be cleaned at the best angle during rotation, thereby more effectively removing metal chips.

[0043] Of course, as another embodiment, the brush 32 comprises a plurality of bristles arranged in a spaced manner on the outer circumferential surface of the sleeve 31. The plurality of bristles are arranged in a spaced manner along the axial direction of the sleeve 31 or along the length direction of the sleeve 31.

[0044] The arrangement of the plurality of bristles ensures that the bristles can cover a wider area when rotating, reduces the omission during cleaning, and improves the cleaning coverage. In addition, the spaced arrangement design reduces the mutual interference between the bristles, reduces the risk of long strip or fibrous dirt winding around the bristles, and maintains the cleaning efficiency and service life of the bristles. Whether the bristles are arranged in a spaced manner along the axial direction or along the length direction, uniform contact with the surface to be cleaned can be ensured when rotating or moving, avoiding the difference in cleaning effect caused by uneven distribution of the bristles, and improving the uniformity and consistency of cleaning.

[0045] It should be noted that the material of the brush 32 is wear-resistant nylon or metal wire. The wear-resistant nylon or metal wire is selected as the material of the brush 32, and both of these two materials have excellent wear resistance, can withstand long-time and high-intensity cleaning operation, significantly prolongs the service life of the brush 32, reduces the replacement frequency, and reduces the maintenance cost.
