Description

Technical Field

[0001] This disclosure relates to a power tool, and more particularly to a guide assembly and a power tool including the guide assembly. Background Technology

[0002] When decorating an interior, flooring, tiles, wall tiles, and other decorative materials are usually laid on walls or floors in a spliced ​​manner, leaving gaps between them. These gaps often trap dust, hardened cement, and other impurities. These residues can interfere with the subsequent application of grout sealant, affecting the overall aesthetics.

[0003] Therefore, after laying the decorative panels, grout cleaning is necessary before applying grout to remove any remaining impurities from the gaps. Existing grout cleaning tools typically use a cutting device with a guide assembly to allow the saw blade to remove impurities from the gaps during operation. However, the removed impurities cause environmental pollution and are difficult to clean, causing significant inconvenience and trouble during the process.

[0004] To solve the above problems, in the prior art, a dust collection cover is installed outside the saw blade, and an external vacuum cleaner sucks the cleaned-up impurities into the vacuum cleaner through the dust collection cover. Utility Model Content

[0071] The technical solutions of this disclosure will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0073] In the description of this disclosure, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this disclosure described below can be combined with each other as long as they do not conflict with each other.

[0074] See Figure 1 and Figure 2 As shown in one embodiment of this application, the power tool includes a cutting assembly 10 and a guiding assembly 20. The cutting assembly 10 includes a saw blade 12, which, when operating, drives the saw blade 12 to cut wood, metal, etc. Furthermore, when the cutting assembly 10 is mounted on the guiding assembly 20, it can be used to remove residual cement or other impurities from grout lines in tiles, or to cut crevices of the same depth in wood or metal.

[0075] To clearly describe the guide assembly 20 and the power tool formed by the joining of the cutting assembly 10 and the guide assembly 20 in this embodiment, it is defined that when the operator holds the grip of the power tool, the power tool is operated in the front-to-back direction to cut or clean seams, and the operator is facing forward. The operator's right-hand side is the right side, the left-hand side is the left side, and the operator's height direction is the up-down direction.

[0076] Specifically, refer to Figure 1 and Figure 2 The cutting assembly 10 includes a cutting body 11, a saw blade 12 mounted on the cutting body 11, and a handle assembly 13. The cutting body 11 includes a housing 111 and a motor housed within the housing 111. The motor drives the tool spindle 116 to rotate, which in turn drives the saw blade 12 to rotate. The saw blade 12 includes a saw blade plane, which is the rotation plane of the saw blade. In addition, a guard 14 is installed at the end of the tool spindle 116 where the saw blade 12 is mounted.

[0077] Further, continue to participate Figure 1 and combined Figure 2 As shown, in this embodiment, the handle assembly 13 includes a grip portion 131 and a battery mounting portion 132. The battery mounting portion 132 is operably connected to a battery 40 to power a motor via a control component (not shown) housed within the grip portion 131 or the battery mounting portion 132. Furthermore, in this embodiment, the handle assembly 13 and the cutting body 11 are two separate, separable structures for ease of installation.

[0078] Further, continue to participate Figure 1 As shown, the guide assembly 20 engages with the cutting assembly 10 to guide the saw blade 12 of the cutting assembly 10 in a direction parallel to the plane of the saw blade. Figure 3 As shown, the guide assembly 20 includes a guide plate 21 and at least one guide wheel 22. The guide plate 21 has a longitudinal axis I1, which overlaps with the longitudinal axis of the grip portion 131. The guide assembly 20 guides the saw blade 12 in a direction parallel to the longitudinal axis I1. The power tool, after the cutting assembly 10 and the guide assembly 20 are engaged, is used for crevices cleaning. During use, the guide wheel 22 and the saw blade 12 are aligned and placed into the crevices to be cleaned, and then the motor is activated to drive the saw blade 12 to rotate. The operator holds the grip portion 131 and pushes the power tool forward or backward, thereby cleaning out impurities such as cement from the crevices as the saw blade 12 rotates. Furthermore, the power tool, after the cutting assembly 10 and the guide assembly 20 are engaged, can not only be used for crevices cleaning but also for cutting. When used for cutting, it can be used to cut wood or metal to create crevices of the same depth.

[0079] When the guide assembly 20 engages with the cutting assembly 10, the cutting body 11 and the motor are positioned horizontally on the guide assembly 20, and the central axis I2 of the motor is parallel to or overlaps with the rotation axis I3 of the saw blade 12. (The reference is missing.) Figure 1 and Figure 2 As shown, the cutting body 11 and the motor are horizontally placed on the guide assembly 20, with the cutting body 11 and the motor positioned transversely to the longitudinal axis I1 of the guide plate 21.

[0080] In this embodiment, when the guide assembly 20 is engaged with the cutting assembly 10, the cutting body 11 and the motor are horizontally positioned on the guide assembly 20. Therefore, there is no need to provide a reversing structure such as a bevel gear, allowing the guide assembly 20 to guide the saw blade 12 in a direction parallel to the plane of the saw blade, that is, in a direction parallel to the longitudinal axis I1 of the guide plate 21. Thus, a reversing device can be omitted, reducing the size of the power tool used for cleaning seams in this embodiment, which is beneficial for the miniaturization and weight reduction of the power tool in this embodiment.

[0081] Further, continue to participate Figure 1As shown, in this embodiment, the angle between the longitudinal axis I1 and the central axis I2 of the motor is between 80° and 100°. Preferably, the angle between the longitudinal axis I1 and the central axis I2 of the motor is 90°. Furthermore, in this embodiment, the guide plate 21 is a long strip structure; in optional embodiments, the guide plate 21 can also be a cube structure. Additionally, in optional embodiments, the motor output shaft can extend along the longitudinal axis I1 of the guide plate 21, and a bevel gear can be provided between the motor output shaft and the tool spindle 116 so that the tool spindle 116 is transverse to the guide plate 21. Furthermore, the grip 131 may not be along the longitudinal axis I1 of the guide plate 21; for example, the grip can be formed directly on the top of the cutting body 11, allowing the operator to directly grasp the grip to drive the assembled power tool.

[0082] In addition, in an optional embodiment, the cutting assembly 10 may also be a manual tool structure with a saw blade 12 that is not driven by a motor. After the cutting assembly 10 is engaged with the guide assembly 20, the operator manually pushes the combined tool so that the guide wheel 22 and the saw blade 12 rotate simultaneously.

[0083] Furthermore, participants Figure 4 and Figure 5 As shown, in this embodiment, the guide wheel 22 includes a base 221 and a guide portion 222 surrounding the base 221, wherein the guide portion 222 has a tip 222A facing away from the base 221. In this embodiment, because the tip 222A is formed at the end of the guide portion 222 facing away from the base 221, the guide wheel 22 can enter narrower gaps, thus making the power tool used for gap cleaning in this embodiment applicable to a wider range of scenarios. Figure 5 As shown, the preferred angle of the tip 222A is between 10° and 90°.

[0084] Continue to participate Figure 3 As shown, the guide assembly 20 also includes a dust collection structure disposed on the guide plate 21, which includes a dust outlet 203 for engaging with an external vacuum cleaner. In this embodiment, by disposing of the dust collection structure on the guide plate 21, there is no need for an additional dust collection cover for dust collection, resulting in a simple and compact structure. Furthermore, by disposing of the dust collection structure on the guide plate 21, the problem of the dust cover swinging due to dust collection through it is avoided, thereby improving the stability of the power tool during operation.

[0085] Continue to participate Figure 3 As shown, the dust collection structure includes a suction port 201 disposed on the guide plate 21 and a dust chamber 202 connecting the suction port 201 and the dust outlet 203. The suction port 201 is disposed on the side wall of the guide plate 201 near the saw blade 12. Furthermore, continue to refer to... Figure 3As shown, in this embodiment, the dust collection structure also includes a dust outlet pipe 23, a dust outlet 203 is formed on the top surface of the dust collection pipe 23, and a dust chamber 202 is formed between the dust collection port 201 and the dust outlet 203. The dust chamber 202 includes a portion located on the guide plate 21 and a portion located on the dust outlet pipe 23.

[0086] In use, the dust hose of the external vacuum cleaner can be connected to the dust outlet pipe 23. Thus, when the power tool in this embodiment performs seam cleaning, the rotation of the saw blade 12 removes dust, cement, and other impurities from the gaps in the board material. Then, under the suction of the external vacuum cleaner, the impurities are drawn into the dust chamber 202 located on the guide plate 21 through the suction port 201, and after passing through the dust chamber 202 located on the dust outlet pipe 23, they enter the external vacuum cleaner through the dust outlet 203. Furthermore, in this embodiment, the external vacuum cleaner has a suction hose that is sleeved over the outside of the dust outlet pipe 23, or inserted into the dust outlet pipe 23 to connect with it. In addition, combined with... Figure 9 As shown, a connecting port 204 is provided at the top of the guide plate 21, which connects the part of the dust chamber 202 located on the guide plate 21 and the part of the dust chamber 202 located on the dust outlet pipe 23. In an optional embodiment, the dust outlet pipe 23 may not be provided, and the connecting port 204 is used as the dust outlet of the dust collection structure, and the suction pipe of an external vacuum cleaner can be directly inserted into the guide plate 21.

[0087] Furthermore, since impurities are flung out along the tangential direction of the saw blade 12 under the rotation of the saw blade 12, the dust suction port 201 should be located close to the edge of the saw blade 12 when the cutting assembly 10 is engaged with the guide assembly 20. The dust suction port 201 can be located in front of or behind the saw blade 12, without any specific limitation.

[0088] Continue to participate Figure 3 and combined Figure 1 As shown, according to the research of technicians, when the radius of the saw blade is R, the dust suction port 201 is set in the direction along the longitudinal axis I1 of the guide plate 21, and the distance from the central axis of the tool spindle 116 is in the range of 0.5R to 1.5R, the dust suction effect is better.

[0089] Furthermore, in this embodiment, the suction port 201 is rectangular in shape. In optional embodiments, the suction port 201 can also be circular or other shapes, and the dust outlet 203 is preferably circular. The shapes of the suction port 201 and the dust outlet 203 are not specifically limited here, and are subject to actual conditions.

[0090] Further, continue to participate Figure 3As shown, the guide plate 21 of this embodiment has a mounting groove 200. When the cutting assembly 10 is engaged with the guide assembly 20, the cutting body 11 is at least partially placed within the mounting groove 200. In this embodiment, since the guide plate 21 has a mounting groove 200 for mounting the cutting body 11, displacement of the cutting body 11 relative to the guide plate 21 can be avoided when the cutting body 11 is mounted on the guide plate 21. Simultaneously, since the cutting body 11 is at least partially placed within the mounting groove 200, the center of gravity of the cutting assembly 10 is lower, resulting in a more stable center of gravity and less wobbling when the power tool of this embodiment is used for cleaning. The shape of the mounting groove 200 is adapted to the shape of the cutting body 11, further preventing displacement of the cutting assembly 10 and making the connection between the cutting assembly 10 and the guide assembly 20 more stable. In this embodiment, the height of the cutting body 11 in the direction perpendicular to the longitudinal axis I1 of the guide plate 21 is H, and the depth of the mounting groove 200 is less than or equal to 1 / 2H.

[0091] Furthermore, in this embodiment, the reference... Figure 3 and combined Figure 1 As shown, guide wheels 22 are positioned on both sides of the mounting groove 200, i.e., the cutting body 11, to improve the stability and accuracy of guidance. In optional embodiments, such as Figure 8 As shown, the guide wheel 22 can also be set only at the rear of the mounting slot 200, which makes the structure in front of the mounting slot 200 compact, improves accessibility when using the power tool, and facilitates operation in confined spaces.

[0092] Furthermore, since impurities generated by the saw blade 12 during operation are thrown out along the tangent of the saw blade 12, some impurities are thrown away from the dust collection port 201, resulting in poor dust collection performance. Therefore, [further details are needed]. Figure 7 and Figure 8 As shown, the dust collection structure also includes a baffle 24 extending laterally from the side wall, with at least a portion of the suction port 201 located between the baffle 24 and the saw blade 12. Thus, the baffle 24 blocks impurities generated during the operation of the saw blade 12, keeping them near the suction port 201 and improving the dust collection effect.

[0093] Technicians discovered that during operation, approximately 90% of the debris ejected from power tools falls within the area where the angle between the tangent of the saw blade 12 and the working plane is between 45° and 60°. Therefore, placing the baffle 24 at the edge of this area ensures that the vast majority of debris is blocked within this region. Furthermore, by placing the suction port 201 within this area, most of the debris can be removed by an external vacuum cleaner. Technicians further discovered that... Figure 7As shown, the minimum distance between the baffle 24 and the edge of the saw blade 12 is L. Among them, when 0mm < L ≤ 20mm, the dust suction effect is better. In addition, in this embodiment, the baffle 24 and the dust suction port 201 are located in front of the saw blade 12. In an alternative embodiment, the baffle 24 and the dust suction port 201 can also be located behind the saw blade 12. When the baffle 24 and the dust suction port 201 are located in front of the saw blade 12, the saw blade 12 is driven to rotate clockwise. At this time, most of the impurities are thrown forward, and most of the impurities are blocked by the baffle 24 located in front of the saw blade 12 and sucked away by the dust suction port 201. When the baffle 24 and the dust suction port 201 are located behind the saw blade 12, the saw blade 12 is driven to rotate counterclockwise. At this time, most of the impurities are thrown backward, and most of the impurities are blocked by the baffle 24 located behind the saw blade 12 and sucked away by the dust suction port 201.

[0094] Furthermore, in this embodiment, the dust chamber 202 includes a first dust chamber extending in the height direction and a second dust chamber communicating with the first dust chamber; among them, the dust outlet 203 is opened on the first dust chamber, and the projection of the first dust chamber and the dust suction port 201 on the plane parallel to the side wall at least partially overlaps. In this way, the linear distance of the dust chamber 202 can be shortened to enhance the dust suction effect.

[0095] Furthermore, continue to refer to Figure 8 As shown, in this embodiment, the guiding component 20 further includes a position adjusting member for adjusting the distance between the guide wheel 22 and the side wall of the guiding plate 21, so that when the cutting component 10 is engaged with the guiding component 20, the guide wheel 22 and the saw blade 12 can move in a straight line.

[0096] Among them, in this embodiment, the guiding component 20 further includes a guide rod 25. Threads that are screwed together are formed on the guide wheel 21 and the guide rod 25, and the screwed-together threads constitute the position adjusting member. When the guide wheel 22 and the saw blade 12 cannot move in a straight line, by rotating the guide wheel 22 to adjust the relative position between the guide wheel 22 and the guide rod 25, and further adjusting the relative position between the guide wheel 22 and the saw blade 12, so that the two can move in a straight line. In addition, in an alternative embodiment, gaskets can also be provided between the guide wheel 22 and the guiding plate 21 to adjust the position of the guide wheel 21. For example, multiple gaskets with different thicknesses or the same thickness can be provided. When the guide wheel 22 and the saw blade 12 cannot move in a straight line, the guide wheel 21 is disassembled from the guide rod 25, and one or more guide wheels 22 with appropriate thickness are selected to adjust the guide wheel 21 to an appropriate position so that the guide wheel 22 and the saw blade 12 move in a straight line.

[0097] Furthermore, in existing technologies, the cutting assembly 10 and the guide assembly 20 are typically fixedly connected, which prevents the cutting assembly 10 from being used as a cutting machine independently. In some cases, the cutting assembly 10 and the guide assembly 20 are detachably connected via clamps, where one end of the clamp is fixed to the guide plate 21, and then the clamp is stretched across the cutting body 11 before the other end is fixed to the guide plate 21. This clamp fixing method is complex, cumbersome to operate, and not very secure. Therefore, after research, technicians designed a simple, reliable, and easy-to-operate connection structure to connect the cutting assembly 10 and the guide assembly 20.

[0098] Continue to participate Figure 8 As shown, in this embodiment, the power tool further includes a connecting component for detachably engaging or disengaging the cutting component 10 and the guiding component 20. In this embodiment, when the cutting component 10 and the guiding component 20 are engaged via the connecting component, the combined power tool can be used as a gap-cleaning tool to remove impurities from gaps between boards. When the cutting component 10 and the guiding component 20 are disengaged, the cutting component 10 can be used as a standalone conventional cutting tool, for example, for cutting wood, metal, etc. Since the cutting component 10 and the guiding component 20 can be detachably engaged via the connecting component, the power tool of this embodiment can not only be used for gap cleaning between boards but also for conventional cutting, meaning one power tool can be used in multiple scenarios, improving the versatility of the power tool in this embodiment. Furthermore, the cutting component 10 can also be fixedly connected to the guiding component 20, thus allowing the power tool of this embodiment to be used only for gap cleaning. The connection relationship between the cutting component 10 and the guiding component 20 is not specifically limited here and is subject to actual use.

[0099] Further, continue to participate Figure 6 and combined Figure 8 As shown, in this embodiment, the connecting components include a first connecting component 30 and a second connecting component 40 located on both sides of the cutting body 11.

[0100] Among them, participants Figure 9 and Figure 10 and combined Figure 11 As shown, in this embodiment, at least one of the first connecting component 30 and the second connecting component 40 includes a first snap-fit ​​portion 31 and a second snap-fit ​​portion 32 that can be operably engaged. The first snap-fit ​​portion 31 is disposed on the guide plate 21, and the second snap-fit ​​portion 32 is disposed on the cutting body 11.

[0101] In this embodiment, the first connecting component 30 and the second connecting component 40 are provided on both sides of the cutting body 11 to improve the stability of the connection between the cutting component 10 and the guide component 20. Furthermore, at least one of the first connecting component 30 and the second connecting component 40 is configured to be respectively disposed on the guide plate 21 and the cutting body 11, and to be operably engaged with a first snap-fit ​​portion 31 and a second snap-fit ​​portion 32. This allows for convenient and quick connection and disassembly of the cutting component 10 and the guide component 20.

[0102] Further, continue to participate Figure 10 and Figure 11 As shown, the first latching part 31 includes a movable part 311. When the cutting assembly 10 is mounted on the guide assembly 20, the movable part 311 can respond to the operator's operation to switch from a first position separated from the second latching part 32 to a second position engaged with the second latching part 32.

[0103] Specifically, such as Figure 10 As shown, in this embodiment, the active part 311 includes an operation part 3112 and an action part 3111. When the cutting assembly 10 is mounted on the guide assembly 20, in response to a first operation applied by the operator to the operation part 3112, the action part 3111 engages with the second locking part 32, and in response to a second operation applied by the operator to the operation part 3112, the action part 3111 disengages from the locking part 32.

[0104] Specifically, such as Figure 10 As shown, in this embodiment, the actuating part 3111 is bent into an inverted L-shape, and the operating part 3112 is integrally formed with the actuating part 3111. In an optional embodiment, the actuating part 3111 can also be snapped into the operating part 3112, which is not specifically limited. An insert 31111 is formed at the top of the actuating part 3111, and a post 31112 is formed at the bottom of the actuating part 3111. In addition, the second snap-fit ​​part 32 includes a first slot formed on the cutting body 11.

[0105] Furthermore, such as Figure 10As shown, in this embodiment, the first engaging portion 31 further includes a first limiting portion 313, which is configured to restrict the movement of the movable portion 311 between a first position and a second position. Specifically, the first limiting portion 313 includes a first limiting groove 313A. In this embodiment, the first limiting groove 313A is disposed on and penetrates the guide plate 21. At least a portion (lower part) of the movable portion 3111 is located within the first limiting groove 313A, and the movable portion 3111 moves between the first position and the second position under the restriction of the first limiting groove 313A. Specifically, in this embodiment, since the first limiting groove 313A is formed within the guide plate 21, the guide plate 21 forms a sidewall of the first limiting groove 313A to restrict the movement of the movable portion 3111.

[0106] Furthermore, in combination Figure 12 As shown, the first latching part 31 also includes an elastic reset part 312, which is configured to reset the movable part 3111 from the first position to the second position.

[0107] Specifically, in this embodiment, a first limiting wall 3131 is formed on the upper surface of the guide plate 21, and a second limiting wall 3132 is formed on the lower surface. The first limiting wall 3131, the guide plate 21, and the second limiting wall 3132 together constitute a first limiting groove 313A extending in the vertical direction. In addition, the second limiting wall 3132 also forms a receiving groove 313B extending in the front-back direction, which communicates with the first limiting groove 313A. The elastic reset part 312 is a spring, with one end abutting against the inner wall of the second limiting wall 3132 and the other end sleeved on the post 31112.

[0108] Before the cutting assembly 10 is installed on the guide assembly 21, the movable part 311 is in a second position (initial position) under the action of a spring. The operator applies a second operation to the operating part 3112, which is to move the operating part 3112 in a second direction, that is, to pull the operating part 3112 away from the mounting groove 200. The movable part 3111 moves away from the mounting groove 200 against the spring force until it is in the first position. In this first position, the movable part 311 makes way for the cutting main assembly 10, so that the cutting assembly 10 can be installed in the mounting groove 200 of the guide assembly 21. After the cutting assembly 10 is installed in the mounting slot 200, the operator applies a first operation to the operating part 3112, which is to release the operating part 3112. Then, under the action of the spring force, the lower movable part 3111 is driven to return to the second position. At this time, the insert 31111 of the operating part 311 is inserted into the first slot, so that the first locking part 31 and the second locking part 32 are locked together, completing the connection between the cutting assembly 10 and the guide assembly 21.

[0109] Further, continue to participate Figure 10 and combined Figure 9 As shown, in this embodiment, the first latching portion 31 further includes a second limiting portion 314, which is fixed to the guide plate 21 and configured to prevent the movable portion 311 from displacing in the vertical direction. Specifically, in conjunction with... Figure 10 As shown, in this embodiment, the second limiting part 314 is a sheet-like metal structure, which is fixed to the first limiting wall 3131 of the first limiting part 311 by a first screw 315. A second limiting groove 313C is formed between the second limiting part 314 and the second limiting wall 3131. The insert 31111 can move in the front-back direction within the second limiting groove 313C, but cannot move in the vertical direction due to the restriction of the second limiting part 314.

[0110] Further, continue to participate Figure 10 and Figure 11 As shown, the second connecting assembly 40 includes a first engaging portion 41 and a second engaging portion 42 that can be operably engaged. The first engaging portion 41 is disposed on the guide plate 21, and the second engaging portion 42 is disposed on the cutting body 11. When the cutting assembly 10 is mounted on the guide assembly 20, the first engaging portion 41 can be operably engaged with the second engaging portion 42.

[0111] Specifically, as shown in the figure, a mounting base 43 is provided on the upper surface of the guide plate 21. The first joint 41 is a sheet-like metal structure, which is fixed to the mounting base 43 by a second screw 44. The second joint 42 is a second slot provided on the cutting body 11.

[0112] When installing the cutting assembly 10 onto the guide assembly 20, the operator pulls the operating part 3112 away from the mounting groove 200. The movable part 3111 overcomes the spring force and moves away from the mounting groove 200, remaining in the first position, allowing the movable part 311 to make way for the main cutting assembly 10. Then, the operator places the cutting body 11 into the mounting groove 200, causing the first engaging part 41 to insert into the second slot, completing the connection on one side of the cutting assembly 10 and the guide assembly 20. Finally, the operator releases the operating part 3112, and the movable part 3111 returns to the second position under the drive of the spring. At this time, the insert 31111 of the movable part 311 inserts into the first slot, causing the first engaging part 31 to engage with the second engaging part 32, completing the connection on the other side of the cutting assembly 10 and the guide assembly 21.

[0113] Furthermore, participants Figure 10 and combined Figure 12As shown, the power tool in this embodiment also includes a positioning part, which includes a first positioning part 51 and a second positioning part 52. The first positioning part 51 is disposed on the guide plate 21, and the second positioning part 52 is disposed on the cutting body 11. When the cutting assembly 10 is installed on the guide assembly 21, the first positioning part 51 and the second positioning part 52 can be operably engaged.

[0114] Specifically, as shown in the figure, the first positioning part 51 in this embodiment includes a boss, and the second positioning part 52 includes a positioning groove located on the cutting body 11. Before installing the cutting assembly 10 onto the guide assembly 20, the boss and the positioning groove can be aligned first. Then, the cutting body 11 is installed in the mounting groove 200, and the boss is inserted into the positioning groove to engage the first positioning part 51 and the second positioning part 52. Further, in this embodiment, the mounting groove 200 is arranged transversely to the guide 21. The first positioning part 51 is disposed within the mounting groove 200 and close to the side wall of the guide 21. The second positioning part 52 is disposed at a position opposite to the first positioning part 51 on the cutting body 11. This positioning part is not only used to align the cutting body 11 and the guide plate 21 when the cutting assembly 10 is installed on the guide assembly 21, but also to restrict the movement of the cutting body 11 in the left and right directions after the cutting assembly 10 is installed on the guide assembly 21. Furthermore, as shown in the figure, in this embodiment, the first positioning part 51 includes two protrusions located on the same arc line, and the second positioning part 52 includes an arc-shaped positioning groove. Both protrusions are accommodated in the same positioning groove, which facilitates installation. In an optional embodiment, two positioning grooves can also be provided on the cutting body 11, with the protrusions and positioning grooves corresponding one-to-one, thereby enhancing the accuracy of positioning and the reliability of limiting.

[0115] Furthermore, participants Figure 13 and Figure 14 As shown, in an optional embodiment, the first engaging portion 31 includes a movable portion 3110 and a seat 317. The movable portion 3110 includes an actuating portion 31110 and an operating portion 31120. The seat 317 is fixed to the guide plate 21, and the operating portion 31120 is pivotally connected to both the seat 317 and the actuating portion 31110. In response to an operator operating the operating portion 31120 in a first direction, the actuating portion 31110 pivots toward the second engaging portion 32 until it engages with the second engaging portion 32; and in response to an operator operating the operating portion 31120 in a second direction opposite to the first direction, the actuating portion 31110 pivots toward a direction away from the second engaging portion 32 to disengage from the second engaging portion 32.

[0116] Continue to participate Figure 13 and join Figure 14As shown, the operating part 31120 is pivotally connected to the base 317 via a pivot 318, and the actuating part 31110 is pivotally connected to the operating part 31120. In this embodiment, the pivot 318 and the actuating part 31110 are pivotally connected to the opposite ends of the operating part 31120, respectively. When the cutting assembly 10 engages with the guiding assembly 20 and responds to the operator operating the operating part 31120 in the first direction Y, the actuating part 31110 pivots toward the second engaging part 32 until it engages with the second engaging part 32.

[0117] Specifically, in this embodiment, the second engaging portion 32 includes a first hook, as shown in the figure. The operator can operate the end 31120A of the operating portion 31120 to rotate the operating portion 31120 about the pivot 318 in the first direction Y until it engages with the second engaging portion 32, i.e., the first hook. When the operating portion 31120 responds to the operator operating the operating portion 31120 in a second direction opposite to the first direction Y, the actuating portion 31110 moves away from the second engaging portion 32 to disengage from the second engaging portion 32, i.e., the first hook.

[0118] In this embodiment, the quick-release structure formed by the first connecting component 32 shown in the figure enables the cutting component 10 and the guiding component 20 to be quickly installed and disassembled.

[0119] Furthermore, participants Figure 15 and join Figure 16 As shown, the second connecting component 40 in this embodiment includes a first engaging portion 41 and a second engaging portion 42 that are operable to engage. The first engaging portion 41 is disposed on the guide plate 21 and includes a second hook that extends toward the cutting body 11 and is arranged in an inverted L-shape. The first engaging portion 42 is disposed on the cutting body 11 and includes a protrusion extending from the cutting body 11.

[0120] When the cutting assembly 10 is engaged with the guide assembly 20, the operating part 31120 can be operated to rotate about the pivot 318 in the second direction (i.e., toward the second engaging part 32), causing the actuating part 31110 to move away from the second engaging part 32 to avoid interference during installation. Then, the cutting body 11 is installed in the mounting groove 200 of the guide plate 21, and the first engaging part 41, i.e., the second hook, engages with the second engaging part 42, i.e., the protrusion. Finally, the operator can operate the operating part 31120 to rotate about the pivot 318 in the first direction Y (i.e., away from the second engaging part 32) until it engages with the second engaging part 32, i.e., the first hook. This securely connects the cutting assembly 10 and the guide assembly 20. In this embodiment, the connecting assembly 40 and the limiting assembly 50 cooperate to ensure a secure connection between the cutting assembly 10 and the guide assembly 20.
