[0055] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0056] Please refer to Figures 1 to 19. This invention discloses a cutting device 100 for cutting a surface 200, specifically for cutting concrete layers, cement layers, etc., laid on the surface 200. Of course, it can also be used to cut materials such as tiles and stones. This invention does not limit this application.

[0057] In this embodiment, the cutting device 100 includes a cutting guide carriage 10 and a cutting assembly 7 disposed on the cutting guide carriage 10. The cutting guide carriage 10 is used to mount the cutting assembly 7 and drive the cutting assembly 7 to move relative to the cutting surface 200.

[0058] The cutting guide carriage 10 includes a direction adjustment component 1, a traveling component, a cutting depth adjustment component 4, a lateral adjustment component 5, and a frame 6. The frame 6 is used to mount and support the cutting guide carriage 10 and provides a mounting base for the aforementioned components. The traveling component is located on the side of the frame 6 near the surface to be cut 200 and includes guide wheels 2 and support wheels 3. The traveling component allows the frame 6 to move on the surface to be cut 200 and provides support for the frame 6. The direction adjustment component 1 adjusts the offset angle of the guide wheels 2 relative to the frame 6, allowing the guide wheels 2 to deflect relative to the frame 6, thereby adjusting the direction of movement of the cutting guide carriage 10. The cutting depth adjustment component 4 adjusts the distance between the guide wheels 2 and the surface to be cut 200, thereby adjusting the depth at which the cutting component 7 cuts the surface 200. The lateral adjustment component 5 finely adjusts the cutting component 7 left and right, ensuring that the cutting component 7 and the traveling direction of the cutting guide carriage 10 are parallel. Of course, in other embodiments, the cutting guide carriage 10 may not include all of the above-mentioned components, as long as it includes components that satisfy the purpose of this invention.

[0059] The frame 6 includes a mounting bracket 61 and a fixed bracket 63 and a rotating bracket 62 disposed on both sides of the mounting bracket 61.

[0060] Mounting bracket 61 provides support and a mounting base for the cutting guide carriage 10. Mounting bracket 61 includes a base plate 611, a fixing rod 612, and a mounting shaft 613. The base plate 611 is positioned close to and parallel to the surface to be cut 200 (e.g., the ground) to improve the connection strength of the frame 6. The cutting assembly 7 is fixedly mounted on the base plate 611. Specifically, the base plate 611 has a fixing groove, and the bottom of the cutting assembly 7 is fixed within the fixing groove, thereby securing the cutting assembly 7 to the base plate 611. The fixing groove can also be designed to accommodate cutting assemblies 7 of different sizes. Two support wheels 3 are fixedly connected to the base plate 611 via the mounting shaft 613 to support the cutting guide carriage 10 and facilitate its movement. One end of the fixing rod 612 is fixedly connected to the fixing frame 63, and the other end is rotatably and detachably connected to the rotating frame 62.

[0061] Furthermore, the mounting bracket 61 is also provided with a fine-tuning structure 614, which is used to adjust the distance between the base plate 611 and the two support wheels 3, thereby changing the distance between the cutting component 7 and the two support wheels 3. This allows the cutting component 7 to be closer to the wall from both left and right directions, thereby increasing the cutting range.

[0062] The fine-tuning structure 614 includes a fine-tuning bracket 6141 and a fixing nut 6142. The fine-tuning bracket 6141 is fitted onto the mounting shaft 613. The fine-tuning bracket 6141 includes two symmetrically arranged extension arms and a connecting arm positioned between the two extension arms. Both extension arms are fitted onto the mounting shaft 613, and the connecting arm has several first mounting holes. The base plate 611 also has several second mounting holes corresponding to the positions of the first mounting holes. The fixing nut 6142 passes through any pair of first and second mounting holes, thereby fixing the base plate 611 onto the mounting shaft 613. When it is necessary to move the cutting assembly 7 closer to the left support wheel 3, the fine-tuning bracket 6141 is adjusted to move closer to the left support wheel 3, and then fixed with the fixing nut 6142, allowing the cutting assembly 7 to cut closer to the left side of the wall, and vice versa.

[0063] Furthermore, a mudguard 615 is also provided on the mounting bracket 61. The mudguard 615 is formed by extending the end of the base plate 611 near the cutting assembly 7 away from the cutting assembly 7. By providing the mudguard 615, the requirements for dust prevention and splash prevention during the operation of the cutting assembly 7 can be met.

[0064] The fixed frame 63 is fixedly connected to the mounting bracket 61. For example, the fixed frame 63 and the mounting bracket 61 can be combined into a non-moving component or welded body. The rotating frame 62 is rotatably connected to the mounting bracket 61. This arrangement reduces the number of structural parts in the cutting guide trolley 10, making the overall structure compact and facilitating installation and transportation. Furthermore, the rotating frame 62 can move relative to the fixed frame 63, and the angle between the rotating frame 62 and the fixed frame 63 can be adjusted by the cutting depth adjustment component 4.

[0065] The mounting bracket 63 extends rearward and upward from the mounting bracket 61 to serve as the main handle assembly of the cutting guide cart 10, facilitating user pushing and controlling of the cutting component 7. The mounting bracket 63 includes a first handle 631 and a second handle 632 rotatably connected. The first handle 631 is fixedly connected to the fixing rod 612 of the mounting bracket 61, and the second handle 632 is pivotally connected to the first handle 631. The end of the second handle 632 away from the first handle 631 is bent to form the main handle for user pushing. The pivotally connected first handle 631 and second handle 632 allows adjustment of the angle between them, thereby adjusting the height of the main handle assembly of the cutting guide cart 10 to meet the height requirements of users of different heights. Furthermore, the pivotal connection of the first handle 631 and second handle 632 facilitates the rotation, folding, or detachable assembly of the mounting bracket 63 around the connection point of the first handle 631 and second handle 632, minimizing the packaging of the cutting guide cart 10 and facilitating its transportation and installation.

[0066] Furthermore, the first handle 631 is provided with a first engagement part 6311, and the second handle 632 is provided with a second engagement part 6321. The first engagement part 6311 and the second engagement part 6321 are connected by gear engagement to make the connection between the first handle 631 and the second handle 632 more stable.

[0067] Furthermore, a first adjustment knob 633 is provided at the connection between the first handle 631 and the second handle 632. After the first handle 631 and the second handle 632 are adjusted according to the user's height, the angle between the first handle 631 and the second handle 632 is fixed by the first adjustment knob 633, improving the connection stability of the first handle 631 and the second handle 632. In addition, the first adjustment knob 633 can also be used to quickly fold the first handle 631 and the second handle 632, facilitating the quick disassembly and installation of the cutting guide cart 10 and minimizing packaging.

[0068] The rotating frame 62 includes an adjusting rod 621, a support rod 622, and a guide rod 623 arranged sequentially. A sleeve rod 625 extends from the connection point of the support rod 622 and the guide rod 623 towards the mounting bracket 61, and the sleeve rod 625 is fitted onto the fixed rod 612. The rotating frame 62 is rotatably connected to the mounting bracket 61 via the sleeve rod 625 and is detachable. The support rod 622 and the guide rod 623 are fixedly connected and arranged at an angle; preferably, this angle is obtuse to facilitate user movement. The guide rod 623 is fixedly connected to the guide wheel 2, allowing adjustment of the height of the guide rod 623 relative to the cutting surface 200, thereby adjusting the distance between the guide wheel 2 and the cutting surface 200, and thus adjusting the cutting depth of the cutting assembly 7.

[0069] The adjusting rod 621 is located at the end of the support rod 622 away from the guide rod 623 and is detachably connected to the support rod 622. This allows the rotating frame 62 to be detachably assembled with the connection between the adjusting rod 621 and the support rod 622 as the center, thereby minimizing the packaging of the cutting guide cart 10 and facilitating its transportation and installation.

[0070] Furthermore, a second adjustment knob 624 is provided at the connection between the adjustment rod 621 and the support rod 622. By providing the second adjustment knob 624, the adjustment rod 621 and the support rod 622 can be quickly disassembled and folded, which facilitates the quick disassembly and installation of the cutting guide trolley 10 and minimizes packaging.

[0071] In another embodiment, the adjusting rod 621 and the support rod 622 are pivotally connected. The adjusting rod 621 has a third engaging portion, and the support rod 622 has a fourth engaging portion. The third and fourth engaging portions are connected by gear meshing. This arrangement allows for adjustment of the angle between the adjusting rod 621 and the support rod 622, thereby meeting the height requirements of users of different heights for the rotating frame 62. Furthermore, pivoting the adjusting rod 621 and the support rod 622 facilitates the rotation and folding of the rotating frame 62 around the connection point of the adjusting rod 621 and the support rod 622, or its detachable assembly, thus minimizing the packaging of the cutting guide cart 10 and facilitating its transportation and installation. The third and fourth engaging portions have the same structure as the first engaging portion 6311 and the second engaging portion 6321; however, they may differ in other embodiments.

[0072] Furthermore, a second adjustment knob 624 is provided at the connection between the adjusting rod 621 and the support rod 622. After the adjusting rod 621 and the support rod 622 are adjusted according to the user's height, the angle between the adjusting rod 621 and the support rod 622 is fixed by the second adjustment knob 624, improving the connection stability between the adjusting rod 621 and the support rod 622. In addition, the second adjustment knob 624 can also be used to quickly fold the adjusting rod 621 and the support rod 622, facilitating the quick disassembly and installation of the cutting guide cart 10 and minimizing packaging.

[0073] The frame 6 is provided with a receiving space 65, in which the cutting component 7 and the water tank 9 are both housed and connected to the frame 6. In addition, the cutting device 100 is automatically pressed down by the weight of the frame 6, the cutting component 7 and the water tank 9 to achieve balance, which can improve cutting efficiency and operating comfort.

[0074] A water tank 9 is positioned between the fixed frame 63 and the rotating frame 62, and above the cutting assembly 7. Specifically, the water tank 9 is located at the top of the frame 6 and is connected to the cutting assembly 7 via piping. A water tank mounting bracket 66 is provided on the side of the second handle 632 facing the receiving space 65. The water tank 9 is mounted on the water tank mounting bracket 66 and fixedly connected to the frame 6. The water tank 9 supplies water to the cutting assembly 7 through water pipes to cool the cutting assembly 7, thereby extending its service life. Furthermore, it can also remove dust from the cutting assembly 7, preventing the generation of excessive dust during operation.

[0075] The cutting assembly 7 also includes a drive assembly 8, which drives the cutting assembly 7 to perform cutting. The cutting assembly 7 is provided with a rear handle 72 and a carrying handle 71. The cutting assembly 7 is fixedly connected to the fixing frame 63 by fixing the rear handle 72 to the fixing frame 63. The drive assembly 8 and the rear handle 72 are either integrally formed or fixedly connected.

[0076] The drive assembly 8 is equipped with a battery housing 81 and a battery pack (not shown) housed within the battery housing 81. The battery pack supplies power to the cutting assembly 7, driving it to cut the surface 200 to be cut. Specifically, the rear handle 72 of the cutting assembly 7 is equipped with a power switch 73 and a start switch 74. When the battery pack is housed within the battery housing 81, pressing the power switch 73 energizes both the battery pack and the start switch 74. Pressing the start switch 74 energizes the cutting assembly 7, driving it to rotate and cut the surface 200 to be cut.

[0077] Please refer to Figures 6-8 and in conjunction with Figures 1-5 for details. The cutting guide vehicle 10 also includes a starting device 64 to facilitate the starting of the cutting assembly 7 and improve the user experience.

[0078] The starting device 64 includes a crankshaft connecting rod 641 and a fixed shaft 645. The fixed shaft 645 is fixedly connected to the rear handle 72 of the cutting assembly 7 and rotatably connected to the crankshaft connecting rod 641, so that the crankshaft connecting rod 641 can rotate relative to the fixed shaft 645.

[0079] The crankshaft connecting rod 641 includes a first end 644 and a second end 642 disposed opposite to each other. The first end is used to connect to the starting assembly, and the second end is used to abut against the starting switch 74. The second end 642 is provided with a starting shaft 643, which is disposed opposite to the starting switch 74. When the crankshaft connecting rod 641 rotates, it can drive the starting shaft 643 to rotate, so that the starting shaft 643 can press the starting switch 74 to activate the cutting assembly 7.

[0080] The starting device 64 includes a spring-loaded member 646. The crankshaft connecting rod 641 includes a first end 644 located away from the second end 642. One end of the spring-loaded member 646 is connected to the first end 644, and the other end is connected to the cutting assembly 7. When the crankshaft connecting rod 641 is subjected to an external force and rotates until the starting shaft 643 abuts against the starting switch 74, the spring-loaded member 646 is stretched. When the external force disappears, the crankshaft connecting rod 641 rotates in the opposite direction under the action of the spring-loaded member 646 to return to the initial position.

[0081] The starting device 64 also includes a starting component, which is disposed on the second handle 632 of the fixed frame 63 and fixedly connected to the first end 644 of the crankshaft connecting rod 641 to drive the first end 644 to move. When the starting component drives the first end 644 to rotate, the second end 642 rotates in the opposite direction and abuts against the start switch 74 to activate the cutting component 7.

[0082] The starting assembly includes a handle 647, a starter 648, and a starting cable 649. The handle 647 is located at the end of the adjusting rod 621 and is fixedly connected to it. The starter 648 is connected to the handle 647 and can rotate relative to it. One end of the starting cable 649 is connected to the starter 648, and the other end is connected to a first end 644. When the starter 648 moves toward the handle 647, it pulls the starting cable 649, causing the crankshaft connecting rod 641 to rotate around a fixed shaft 645, thereby activating the cutting assembly 7. Preferably, the starting cable 649 is a brake cable, and the return spring 646 is a torsion spring.

[0083] Of course, in this embodiment, a limiting device (not shown) can also be provided between the starter 648 and the handle 647 to limit the distance between the starter 648 and the handle 647. Specifically, the starter 648 is limited to move away from the handle 647 so that the starter shaft 643 keeps pressing the start switch 74, so that the cutting component 7 continues to rotate. The specific structure and limiting method of the limiting device can be set according to the actual situation, and the limiting device can also be set in other positions, which is not limited here.

[0084] In other words, when the cutting assembly 7 needs to be started, an external force is applied to the starter 648, causing the starter 648 to move toward the handle 647. This, in turn, pulls the crankshaft connecting rod 641 through the starter cable 649, causing the crankshaft connecting rod 641 to rotate around the fixed shaft 645. At the same time, the spring-loaded member 646 is stretched until the starter shaft 643 abuts against the starter switch 74, causing the cutting assembly 7 to rotate. The external force applied to the starter 648 is then released, and the crankshaft connecting rod 641 returns to its initial position under the drive of the spring-loaded member 646, causing the cutting assembly 7 to stop rotating.

[0085] Referring to Figure 9 and in conjunction with Figure 15, the cutting assembly 7 further includes a self-locking anti-locking structure 75 on its rear handle 72. The cutting guide trolley 10 also includes a lateral adjustment assembly 5 disposed on the side of the fixed frame 63 facing the rotating frame 62. The housing 532 of the lateral adjustment assembly 5 is press-fitted with the self-locking anti-locking structure 75. When the lateral adjustment assembly 5 is installed on the fixed frame 63, the self-locking anti-locking structure 75 is in the unlocked state. This configuration ensures that when the lateral adjustment assembly 5 is installed, it simultaneously presses down the self-locking anti-locking structure 75, keeping it in a pressed-unlocked state. Only the starter 648 needs to be pressed to activate the cutting assembly 7 for cutting. This convenient structure eliminates the need for additional mechanisms to press down the self-locking anti-locking structure 75.

[0086] Furthermore, the cutting guide carriage 10 has a three-wheel arrangement structure. Two support wheels 3 are located at the rear of the frame 6 and are arranged in parallel. One guide wheel 2 is located at the front of the frame 6, serving as a front guide. The guide wheel 2 is mounted on the guide rod 623 of the rotating frame 62 and is arranged side by side with the cutting assembly 7 at the bottom of the frame 6. It is used to adjust the distance between the cutting assembly 7 and the surface to be cut 200. In addition, the direction of movement of the cutting guide carriage 10 can also be adjusted by the guide wheel 2.

[0087] Please refer to Figures 1-3 and 14. To improve the stability of the cutting assembly 7 on the frame 6, a fixing assembly 626 is provided between the frame 6 and the cutting assembly 7. Specifically, the fixing assembly 626 includes a fixed rotating shaft mounted on the rotating frame 62 and a rotating handle rotatably connected to the fixed rotating shaft. The rotating handle includes a first handle and a second handle set at an angle. The first handle is used for the user to grip, and the second handle is used to abut against the handle 71 of the cutting assembly 7 to improve the installation stability of the cutting assembly 7.

[0088] Furthermore, a metal spring is provided below the fixed pivot, and the metal spring has a protrusion. A first abutting groove and a second abutting groove are respectively provided at the bottom and side of the first handle. When the first handle is pressed down, causing the second handle to abut against the handle 71, the first abutting groove engages with the protrusion, and the rotating handle is in a pressed and fixed state. When the first handle is pulled up, causing the second handle to separate from the handle 71, the second abutting groove engages with the protrusion, and the rotating handle is in a released state. By setting the first and second abutting grooves and the protrusion, the user receives audible and tactile feedback when pressing down, resulting in a better user experience.

[0089] Please refer to Figures 1, 3, and 10-13. The direction adjustment assembly 1 is located at the end of the guide rod 623 away from the support rod 622, and includes a connecting shaft 11, a sleeve 15, a bearing 12, and a limiting structure 16. The sleeve 15 is fixedly connected to the guide rod 623. The connecting shaft 11 is at least partially located inside the sleeve 15, with a portion protruding outside the sleeve 15 for fixed connection to the guide wheel 2. A first gap 141 exists between the connecting shaft 11 and the sleeve 15. The bearing 12 is located between the connecting shaft 11 and the sleeve 15, and the connecting shaft 11 is offset within the sleeve 15 with the bearing 12 as its axis. The limiting structure 16 is located on the sleeve 15, passes through the sleeve 15, and abuts against the connecting shaft 11 to fix the eccentricity angle between the connecting shaft 11 and the sleeve 15.

[0090] By placing part of the connecting shaft 11 inside the sleeve 15 and connecting the other end to the guide wheel 2, the offset angle of the guide wheel 2 can be adjusted by adjusting the offset angle of the connecting shaft 11 relative to the sleeve 15. Furthermore, the sleeve 15 is fixedly connected to the guide rod 623 of the frame 6. The guide wheel 2 is connected to the frame 6 via the connecting shaft 11 and the sleeve 15 to support the frame 6 and adjust its travel direction. By setting the bearing 12 and the limiting structure 16, the connecting shaft 11 can offset within the sleeve 15 with the bearing 12 as its axis, thereby adjusting the direction of the connecting shaft 11 relative to the sleeve 15. The mutual cooperation between the limiting structure 16 and the connecting shaft 11 fixes the offset angle of the connecting shaft 11 relative to the bearing 12, improving the connection stability between the connecting shaft 11 and the sleeve 15. This allows for convenient adjustment of the travel direction of the guide wheel 2, enabling the support wheel 3 and the guide wheel 2 to maintain parallelism, achieving linear movement of the cutting guide carriage 10, and locking it to satisfy the purpose of linear cutting by the cutting guide carriage 10.

[0091] Specifically, the guide rod 623 is fixedly connected to the sleeve 15, and is connected at the middle position of the sleeve 15. The sleeve 15 can be integrally formed with the frame 6, or the sleeve 15 and the frame 6 can be fixedly connected by welding. The sleeve 15 is set in a direction parallel to the surface to be cut 200 and perpendicular to the travel direction of the cutting guide carriage 10. This setting allows the rotation direction of the guide wheel 2 to be parallel to the travel direction of the cutting guide carriage 10.

[0092] The sleeve 15 is cylindrical and hollow, with a circular inner cavity 151. The connecting shaft 11 is at least partially installed in the inner cavity 151 and can be offset within the inner cavity 151.

[0093] The sleeve 15 is provided with a plurality of fixing holes 152, which are evenly distributed along the outer circumference of the sleeve. The fixing holes 152 and the fixing member 161 together form a limiting structure 16, so as to fix the connecting shaft 11 inside the sleeve 15 through the limiting structure 16.

[0094] The connecting shaft 11 is cylindrical and includes a free section 111, a fixed section 113, and a connecting section 112 disposed between the fixed section 113 and the free section 111. The diameter of the fixed section 113 is larger than the diameter of the connecting section 112, which is larger than the diameter of the free section 111.

[0095] The fixed section 113 and part of the connecting section 112 are disposed within the sleeve 15, and the diameter of the inner cavity 151 of the sleeve 15 is larger than the diameter of the fixed section 113, that is, there is a first gap 141 between the fixed section 113 and the inner wall of the sleeve 15. The first gap 141 is provided to facilitate the installation of the connecting shaft 11 within the sleeve 15, and also to facilitate the use of external tooling to install the connecting shaft 11, so that the connecting shaft 11 is always kept in the initial position during assembly, thereby enabling the guide wheel 2 to be accurately positioned in the ideal position during assembly.

[0096] A groove 114 is provided on the side of the fixed section 113 away from the connecting section 112. The groove 114 is recessed inward from the outer surface of the fixed section 113 and corresponds to the fixing hole 152 on the sleeve 15. The fixing hole 152 passes through the sleeve 15 and is positioned opposite the groove 114, so that one end of the fixing member 161 can pass through the fixing hole 152 and extend into the groove 114 to abut against the bottom of the groove 114, thereby limiting the distance between the connecting shaft 11 and the sleeve 15 and achieving the fixation between the connecting shaft 11 and the sleeve 15. Preferably, the fixing member 161 is a hexagonal screw, which includes a stud and an external thread on the stud. The stud abuts against the bottom of the groove 114, and the fixing hole 152 has an internal thread. The length of the stud extending into the sleeve 15 is adjusted through the threaded connection between the stud and the fixing hole 152, thereby adjusting the distance between the connecting shaft 11 and the sleeve 15. The groove 114 is arranged in a circular groove shape, and the width of the groove 114 is not less than the diameter of the stud, so that the stud can extend into the groove 114 and abut against the bottom of the groove 114.

[0097] The groove 114 is arranged around the outer surface of the fixed section 113 of the connecting shaft 11. At least three limiting structures 16 are provided, and the at least three limiting structures 16 are evenly distributed along the outer peripheral surface of the sleeve 15. That is, at least three fixing holes 152 are provided on the outer peripheral surface of the sleeve 15, and the fixing holes 152 are evenly distributed on the sleeve 15 and correspond to the groove 114.

[0098] Preferably, there are four fixing holes 152, which are evenly distributed on the outer circumferential surface of the sleeve 15. That is, in the diameter direction of the sleeve 15, the included angle between two adjacent fixing holes 152 is 90°, and two opposite fixing holes 152 are arranged on the same straight line. Of course, in other embodiments, there can be three fixing holes 152, in which case the included angle between two adjacent fixing holes 152 is 120°. There can also be five, six or other numbers of fixing holes 152, which are not limited here.

[0099] In this embodiment, the groove 114 is arranged around the outer surface of the connecting shaft 11. This arrangement allows the connecting shaft 11 to rotate within the sleeve 15, and regardless of the rotation angle, the fixing member 161 can extend into the groove 114 to fix the distance between the connecting shaft 11 and the sleeve 15. Of course, in other embodiments, the groove 114 can be set as a blind hole, a cut surface, or other limiting device, and the fixing hole 152 is set corresponding to the blind hole. Alternatively, the groove 114 may not be provided on the connecting shaft 11, and the fixing member 161 can directly abut against the outer wall surface of the connecting shaft 11. There are no restrictions here.

[0100] The bearing 12 is disposed on the connecting section 112 of the connecting shaft 11 and is located in the inner cavity 151 of the sleeve 15. The bearing 12 includes an abutment member 121 and a rotating member 123.

[0101] The abutment member 121 abuts against the sleeve 15. The sleeve 15 has an abutment groove 153, and the abutment member 121 is housed within the abutment groove 153 and is interference-fitted with the sleeve 15. Specifically, the connecting section 112 is positioned opposite to the abutment groove 153. The abutment groove 153 is recessed from the inner wall of the inner cavity 151 towards a direction away from the connecting shaft 11; that is, the diameter of the abutment groove 153 is larger than the diameter of the inner cavity 151. The outer surface of the abutment member 121 is cylindrical, and the diameter of the abutment member 121 matches the diameter of the abutment groove 153. The abutment member 121 extends into the abutment groove 153, allowing for an interference-fitted connection between the abutment member 121 and the sleeve 15. This prevents the abutment member 121 from falling out of the sleeve 15 during use and also prevents the abutment member 121 from rotating within the sleeve 15.

[0102] The abutment member 121 is provided with a rotating cavity 122, and the rotating member 123 is housed in the rotating cavity 122 and can rotate within the rotating cavity 122, thereby allowing the connecting shaft 11 to be offset within the sleeve 15 with the rotating member 123 as the axis.

[0103] Furthermore, the rotating cavity 122 is arranged in an arc shape, and the rotating member 123 abuts against the rotating cavity 122, having an arc-shaped surface 125 facing the rotating cavity 122. The surface curvature of the rotating cavity 122 is less than the curvature of the arc-shaped surface 125, so that the rotating member 123 can rotate in any direction within the rotating cavity 122.

[0104] Specifically, the bearing 12 has a shaft hole 124 that passes through the rotating member 123 and the abutment member 121, preventing the abutment member 121 and the rotating member 123 from forming a complete sphere. In the direction perpendicular to the shaft hole 124, the diameter of the rotating cavity 122 matches the maximum diameter of the rotating member 123 and is larger than the diameter of the shaft hole 124, allowing the rotating member 123 to rotate within the rotating cavity 122 but not through the shaft hole 124, thus confining the rotating member 123 within the abutment member 121. Preferably, the bearing 12 is a spherical bearing 12.

[0105] A connecting segment 112 on the connecting shaft 11 passes through the shaft hole 124 of the bearing 12. Specifically, the connecting segment 112 is located at the middle of the connecting shaft 11, and the diameter of the connecting segment 112 is smaller than the diameter of the fixed segment 113. The size of the shaft hole 124 is the same as the size of the connecting segment 112, so that the connecting segment 112 is accommodated in the shaft hole 124 and abuts against the side wall of the shaft hole 124, thereby connecting the connecting shaft 11 to the rotating member 123. Furthermore, the connecting shaft 11 can drive the rotating member 123 to rotate in the rotating cavity 122, so that the connecting shaft 11 rotates about the bearing 12 as the axis. Preferably, the connecting segment 112 and the rotating member 123 are connected by an interference fit, and the connecting shaft 11 can move up and down, left and right, and diagonally relative to the bearing 12.

[0106] The connecting shaft 11 also includes a free section 111 not housed within the sleeve 15. The free section 111 extends into and connects to the guide wheel 2, allowing the guide wheel 2 to rotate about the connecting shaft 11 as its axis. This enables the connection between the guide wheel 2 and the direction adjustment assembly 1. Specifically, the diameter of the free section 111 is smaller than the diameter of the connecting section 112. The guide wheel 2 is fitted onto the outside of the free section 111, and a fastener 18 is provided at the end of the free section 111 to secure the guide wheel 2 between the fastener 18 and the connecting section 112, preventing the guide wheel 2 from falling off during use. Preferably, the guide wheel 2 is tightly connected to the free section 111 via a deep groove ball bearing, preventing the guide wheel 2 from deflecting relative to the connecting shaft 11 and improving the connection stability and accuracy between the guide wheel 2 and the connecting shaft 11.

[0107] Furthermore, the direction adjustment assembly 1 also includes a bushing 13, which is disposed between the sleeve 15 and the connecting shaft 11. That is, the bushing 13 is located within the first gap 141, and a second gap 142 is provided between the bushing 13 and the connecting shaft 11. The bushing 13 is interference-fitted to the sleeve 15 or integrally formed, and the bushing 13 is annular. In the radial direction of the connecting shaft 11, the second gap 142 is not greater than 0.7 mm. Preferably, the second gap 142 is 0.5 mm.

[0108] Specifically, the abutment groove 153 and the fixing hole 152 are respectively located at both ends of the sleeve 15. The bushing 13 is housed in the inner cavity 151 and is located between the abutment groove 153 and the fixing hole 152. The bushing 13 is arranged opposite to the fixing section 113 of the connecting shaft 11. By connecting the bushing 13 and the sleeve 15 with an interference fit, the bushing 13 is prevented from rotating relative to the sleeve 15, thereby preventing the bushing 13 from falling off.

[0109] By setting a bushing 13 inside the sleeve 15 and setting a gap 14 between the bushing 13 and the connecting shaft 11, on the one hand, the offset distance of the connecting shaft 11 inside the sleeve 15 is limited. Specifically, the connecting shaft 11 is offset inside the sleeve 15, and then the angle between the guide wheel 2 and the frame 6 is adjusted with the bearing 12 as the rotation axis, so that the cutting guide carriage 10 deflects when it moves. When the connecting shaft 11 abuts against the bushing 13, the maximum deflection angle of the guide wheel 2 is reached, so as to avoid the cutting guide carriage 10 deflecting too much and causing the cutting component 7 to break.

[0110] On the other hand, to achieve precise positioning during the assembly of the connecting shaft 11 and the guide wheel 2, specifically, when assembling the connecting shaft 11 and the guide wheel 2, an external tooling is inserted between the connecting shaft 11 and the bushing 13. Specifically, a portion of the external tooling is inserted into the second gap 142 to fix the distance between the connecting shaft 11 and the bushing 13, thus stabilizing the connecting shaft 11. Then, the guide wheel 2 is assembled into the free section 111. Since the connecting shaft 11 cannot rotate, the assembly speed of the guide wheel 2 and the connecting shaft 11 is increased, while also improving the assembly accuracy. After the guide wheel 2 and the connecting shaft 11 are assembled, the external tooling can be removed.

[0111] The external tooling can be understood as a device with multiple wedge-shaped jaws arranged in a ring. The wedge-shaped jaws can extend into the inner cavity 151 and into the second gap 142, so that the axis of the connecting shaft 11 overlaps with the axis of the sleeve 15. Of course, this is only an example of external tooling and should not be taken as a limitation. Any device that can fix the connecting shaft 11 relative to the sleeve 15 can be considered external tooling. There are no restrictions here.

[0112] In this embodiment, the offset of the connecting shaft 11 is limited by setting a bushing 13, and the bushing 13 is interference-fitted with the sleeve 15. Of course, in other embodiments, the bushing 13 may not be set, and the offset of the connecting shaft 11 may be limited by limiting the distance between the connecting shaft 11 and the bushing 13; or, the bushing 13 may be integrally formed with the sleeve 15, that is, the bushing 13 extends from the sleeve 15 toward the inner cavity 151, which is not limited here.

[0113] The direction adjustment assembly 1 also includes an end cap 17 connected to the sleeve 15. The size of the end cap 17 matches the size of the inner cavity 151. The end cap 17 is located at the end of the sleeve 15 away from the guide wheel 2, and a portion of the end cap 17 can extend into the inner cavity 151. By covering the inner cavity 151 with the end cap 17, the direction adjustment assembly 1 is aesthetically pleasing while preventing impurities from entering the inner cavity 151.

[0114] In summary, when the direction adjustment assembly 1 is connected to the guide wheel 2, an external tooling is inserted into the second gap 142 to fix the connecting shaft 11 inside the sleeve 15. Then, the guide wheel 2 is fixed in the free section 111, and the guide wheel 2 is restricted to the outside of the free section 111 by the fastener 161. Then, the external tooling is removed. At this time, the connecting shaft 11 can be offset within the range of the bushing 13 with the bearing 12 as the axis to change the angle between the guide wheel 2 and the frame 6. After adjusting the angle between the guide wheel 2 and the frame 6, at least three fasteners 161 are respectively passed through at least three fixing holes 152 and abut against the bottom of the groove 114 to fix the distance between the connecting shaft 11 and the sleeve 15 in each direction. At this time, the distances of the at least three fasteners 161 extending into the sleeve 15 can be the same or different.

[0115] When it is necessary to adjust the angle between the guide wheel 2 and the frame 6, by rotating the fixing parts 161 in different directions, some fixing parts 161 rotate away from the inner cavity 151, while others rotate towards the inner cavity 151. This allows the connecting shaft 11 to shift within the sleeve 15, thereby adjusting the angle between the guide wheel 2 and the frame 6. This allows the guide wheel 2 to be adjusted to any angle as needed during use. After adjusting the angle of the guide wheel 2, the fixing parts 161 of the limiting structure 16 are re-locked, thus achieving the adjustment of the guide wheel 2's angle.

[0116] Furthermore, the guide wheel 2 and the cutting assembly 7 are spaced apart to prevent the cutting assembly 7 from damaging the guide wheel 2 during operation.

[0117] To prevent the guide wheel 2 from interfering with the cutting assembly 7 when it is offset relative to the frame 6, and thus accidentally damaging the guide wheel 2, the cutting guide carriage 10 of the present invention also includes a lateral adjustment assembly 5 to adjust the distance between the cutting assembly 7 and the guide wheel 2.

[0118] Please refer to Figures 1 to 5, and in conjunction with Figures 14 to 16, as shown, the fixed frame 63 and the rotating frame 62 are arranged left and right, that is, in the left-right direction perpendicular to the moving direction of the cutting guide carriage 10, the fixed frame 63 and the rotating frame 62 are offset from each other. Furthermore, the offset distance between the fixed frame 63 and the rotating frame 62 is fixed, that is, in the left-right direction, the fixed frame 63 and the rotating frame 62 have a fixed interval. A receiving space 65 is formed between the fixed frame 63 and the rotating frame 62 to accommodate the cutting assembly 7 and the water tank 9.

[0119] During the cutting process, the cutting component 7 is prone to deviation, causing the running direction of the cutting component 7 to be inconsistent with that of the cutting guide carriage 10. To solve this problem, the fixed frame 63 of the present invention is provided with a lateral adjustment component 5 on the side facing the rotating frame 62. The lateral adjustment component 5 is disposed on the first handle 631 of the fixed frame 63 and is perpendicular to the first handle 631. Furthermore, the lateral adjustment component 5 is fixedly connected to the rear handle 72 of the cutting component 7, thereby fixing the cutting component 7 to the fixed frame 63. By adjusting the lateral adjustment component 5, the left and right offset direction of the cutting component 7 in the cutting guide carriage 10 is adjusted, so that the running direction of the cutting component 7 is parallel to that of the cutting guide carriage 10, thereby allowing the cutting device 100 to run smoothly without obstruction or deviation.

[0120] The lateral adjustment assembly 5 includes a connecting rod 51 mounted on a fixed frame 63, a sliding structure 53 sleeved on the outside of the connecting rod 51, and an adjusting member 54.

[0121] The connecting rod 51 is fixedly connected to the first handle 631 and extends from the first handle 631 toward the receiving space 65 of the frame 6. The setting direction of the connecting rod 51 is parallel to the surface to be cut 200.

[0122] The sliding structure 53 has a sliding hole 531 through which the connecting rod 51 passes. The sliding structure 53 is sleeved on the outside of the connecting rod 51 through the sliding hole 531 and can slide along the connecting rod 51. Furthermore, the sliding structure 53 and the adjusting member 54 are rotatably engaged, and the sliding structure 53 is fixedly connected to the rear handle 72 of the cutting assembly 7. By rotating the adjusting member 54, the distance between the sliding structure 53 and the fixed frame 63 is adjusted, thereby adjusting the left and right offset angle of the cutting assembly 7 on the cutting guide carriage 10, so that the cutting assembly 7 can be parallel to the traveling direction of the cutting guide carriage 10.

[0123] The sliding structure 53 includes a mating portion 55 disposed toward the adjusting member 54. The mating portion 55 includes an extension wall 551 extending toward the adjusting member 54, the extension wall 551 forming a receiving cavity 556. The receiving cavity 556 has an adjusting surface 552 on the side facing the adjusting member 54. The adjusting surface 552 has a height difference along the extending direction of the extension wall 551. This arrangement allows the adjusting block 542 on the adjusting member 54 to press against the sliding structure 53 using the height difference on the adjusting surface 552 when the adjusting member 54 is rotated, thereby allowing the sliding structure 53 to slide left and right along the extending direction of the connecting rod 51.

[0124] Furthermore, the lateral adjustment component 5 also includes an elastic element 52, which is disposed between the fixed frame 63 and the sliding structure 53.

[0125] In this embodiment, the elastic element 52 is a spring, which is sleeved on the connecting rod 51 and positioned between the sliding structure 53 and the first handle 631. One end of the elastic element 52 abuts against the first handle 631, and the other end abuts against the side wall of the sliding structure 53 to provide power for the sliding structure 53 to move away from the first handle 631. When the adjusting member 54 rotates relative to the connecting rod 51 to compress the adjusting surface 552 on the mating part 55, the sliding structure 53 moves on the connecting rod 51 toward the first handle 631 to compress the elastic element 52. At this time, the elastic element 52 has a tendency to push the sliding structure 53 away from the first handle 631.

[0126] Furthermore, the accommodating cavity 556 is provided with a partition plate 557 separating the adjusting surface 552, and the height of the adjusting surface 552 gradually increases from one side of the partition plate 557 to the other side (see Figure 4). That is, the two sides of the partition plate 557 have the greatest height difference. Preferably, this maximum height difference is 1-2 mm. That is, when the adjusting member 54 rotates one revolution on the adjusting surface 552, the sliding structure 53 moves 1-2 mm on the connecting rod 51.

[0127] The adjusting member 54 is fixedly disposed on the side of the connecting rod 51 away from the first handle 631. The connecting rod 51 is also provided with a control groove 513 and a washer 512. The diameter of the control groove 513 is smaller than the diameter of the connecting rod 51. The adjusting member 54 is sleeved on the connecting rod 51 and housed in the control groove 513 to prevent the adjusting member 54 from sliding along the connecting rod 51. The washer 512 is disposed between the locking member 511 and the adjusting member 54 to increase the force-bearing area with the adjusting member 54 and improve the connection stability of the adjusting member 54.

[0128] The adjusting member 54 has a connecting rod hole 541 located at the center. The adjusting member 54 is sleeved on the connecting rod 51 through the connecting rod hole 541 and can rotate around the connecting rod 51. The connecting rod 51 is provided with a locking member 511. One end of the locking member 511 is connected to the connecting rod 51, and the other end abuts against the adjusting member 54 to restrict the adjusting member 54 on the connecting rod 51.

[0129] The adjusting member 54 includes an adjusting block 542 disposed toward the sliding structure 53. The adjusting block 542 protrudes outward from the side of the adjusting member 54 near the first handle 631, that is, the adjusting block 542 can extend into the receiving cavity 556 and abut against the adjusting surface 552. When the adjusting member 54 is rotated, the adjusting block 542 moves along the adjusting surface 552, and the height difference of the adjusting surface 552 drives the sliding structure 53 to move left and right along the direction of the connecting rod 51.

[0130] Furthermore, in order to improve the connection stability between the adjustment surface 552 and the adjustment block 542, the adjustment surface 552 is provided with a first anti-slip part 553 on the side facing the adjustment block 542, and the adjustment block 542 is provided with a second anti-slip part 543 on the side facing the adjustment surface 552, which engages with the first anti-slip part 553.

[0131] In this embodiment, the first anti-slip part 553 includes a plurality of radially arranged racks 554, with toothed grooves 555 between adjacent racks 554. The second anti-slip part 543 includes adjacently arranged locking blocks 5431 and locking grooves 5432. The locking blocks 5431 cooperate with the toothed grooves 555, and the locking grooves 5432 cooperate with the racks 554. By the locking blocks 5431 and locking grooves 5432 engaging with the toothed grooves 555 and racks 554 respectively, the movement stability of the adjusting block 542 on the adjusting surface 552 is improved. At the same time, by providing a plurality of radially arranged racks 554 on the adjusting surface 552, the rotation angle of the adjusting member 54 relative to the sliding structure 53 can be made more precise, thereby allowing for more accurate adjustment of the sliding distance of the sliding structure 53 on the connecting rod 51, and thus precise control of the distance between the cutting assembly 7 and the guide wheel 2. Of course, in other embodiments, only the toothed groove 555 can be provided on the adjusting surface 552 and the locking block 5431 can be provided on the adjusting block 542, or the rack 554 can be provided on the adjusting surface 552 and the locking groove 5432 can be provided on the adjusting block 542, so as to precisely control the rotation of the adjusting member 54 relative to the sliding structure 53. There is no limitation here.

[0132] Furthermore, the rack 554 is also provided with a guide surface and a top surface. The guide surface is set at an acute angle to the adjustment surface 552, and the top surface is parallel to the adjustment surface 552. The locking block 5431 on the adjustment block 542 can move along the guide surface toward the top surface, slide over the top surface to be received in the tooth groove 555, and make the top surface contact the bottom of the locking groove 5432 to limit the rotation angle of the adjustment member 54 relative to the mating part 55. By setting the guide surface to guide the movement of the locking block 5431, the resistance encountered by the adjustment member 54 when rotating is reduced, and the convenience of adjusting the sliding structure 53 of the adjustment member 54 is improved.

[0133] The extension wall 551 has a positioning groove 558 on the side opposite to the receiving cavity 556, and a positioning mark 545 is provided on the outer wall of the adjusting member 54. When the positioning groove 558 and the positioning mark 545 are aligned, the distance between the sliding structure 53 and the adjusting member 54 is in the central position, that is, the elastic member 52 is in a semi-compressed state. In this position, the sliding structure 53 can move towards the fixed frame 63 under the push of the adjusting member 54, and can also move away from the fixed frame 63 under the push of the elastic member 52. By setting the positioning groove 558 and the positioning mark 545, the distance between the adjusting member 54 and the sliding structure 53 is made visible, improving the user experience.

[0134] Furthermore, the adjusting member 54 is provided with at least two adjusting blocks 542, which are arranged in a circular pattern. In this embodiment, the adjusting member 54 is provided with three adjusting blocks 542, all of which are arc-shaped, to achieve stable support.

[0135] An operating part 546 is also provided on the outer wall surface of the adjusting member 54. The operating part 546 is recessed inward from the outer wall surface of the adjusting member 54 to facilitate the user's grip and increase the friction between the user and the adjusting member 54, so as to prevent the user from slipping when adjusting the adjusting member 54.

[0136] In general, when the cutting assembly 7 deviates from the forward direction of the cutting guide carriage 10, the left and right displacement of the cutting assembly 7 can be finely adjusted by the adjusting member 54 and the sliding structure 53 to ensure that the cutting assembly 7 is parallel to the forward direction of the cutting guide carriage 10 and to ensure the cutting effect. For example, by rotating the adjusting member 54, the adjusting block 542 can slide on the adjusting surface 552. The adjusting block 542 presses the sliding structure 53 to move towards the first handle 631 on the connecting rod 51, while compressing the elastic member 52. When the adjustment distance is reached, the sliding structure 53 is fixed at that distance by the engagement of the locking block 5431 on the adjusting block 542 and the toothed groove 555 on the adjusting surface 552. When the sliding structure 53 needs to be adjusted in the opposite direction, the adjusting member 54 is rotated in the opposite direction. The sliding structure 53 moves toward the adjusting member 54 under the push of the elastic member 52, so as to adjust the position of the sliding structure 53 on the connecting rod 51 through the adjusting member 54, thereby fine-tuning the left and right position of the cutting assembly 7, so that the cutting assembly 7 is parallel to the movement direction of the cutting guide carriage 10, so that the cutting device 100 can run smoothly without obstruction or deviation.

[0137] Please refer to Figures 1-5 and Figures 17-20. The cutting depth adjustment component 4 is disposed between the fixed frame 63 and the rotating frame 62 to limit the rotation angle of the rotating frame 62 relative to the fixed frame 63. In addition, it can also adjust the height of the guide wheel 2 relative to the surface to be cut 200, thereby adjusting the cutting depth of the cutting component 7.

[0138] The cutting depth adjustment assembly 4 includes a functional plate 41 and an adjustment structure 42. The functional plate 41 is mounted on the fixed frame 63 and fixedly connected to the mounting bracket 61. The functional plate 41 is perpendicular to the mounting bracket 61 and parallel to the rotating frame 62, ensuring that the rotating frame 62 does not interfere with the functional plate 41 during rotation. The adjustment structure 42 is fixedly connected to the rotating frame 62 and to the adjustment rod 621. When the rotating frame 62 rotates relative to the fixed frame 63, the adjustment structure 42 can move relative to the functional plate 41, and can cooperate with the functional plate 41 to limit the rotation angle of the rotating frame 62 relative to the fixed frame 63. Simultaneously, it limits the height of the guide wheel 2 relative to the surface to be cut 200, thereby limiting the cutting depth of the cutting assembly 7.

[0139] The function plate 41 includes a limiting part 411, which has a plurality of spaced-apart limiting teeth, and a limiting groove 412 is formed between adjacent limiting teeth. That is, the limiting part 411 has a plurality of spaced-apart limiting grooves 412. The limiting grooves 412 are used to engage and fix with the engaging part 427 on the adjusting structure 42 to limit the distance between the fixed guide wheel 2 and the surface to be cut 200, thereby limiting the cutting depth of the fixed cutting assembly 7. It should be noted that the number of limiting grooves 412 can be set according to user needs, so that the cutting depth can be changed by changing the gear.

[0140] The adjustment structure 42 includes a rotating shaft 421 and a crankshaft 422. The rotating shaft 421 is fixed to the adjusting rod 621 of the rotating frame 62, and the crankshaft 422 is movably connected to the rotating shaft 421. One end of the rotating shaft 421 away from the adjusting rod 621 is movably connected to the middle of the crankshaft 422, allowing the crankshaft 422 to rotate around the rotating shaft 421, forming a seesaw-like structure. The crankshaft 422 has a locking part 427 on the side facing the limiting part 411. The locking part 427 is used to lock and fix with the limiting slot 412 on the functional plate 41 to limit the distance between the fixed guide wheel 2 and the surface to be cut 200, thereby limiting the cutting depth of the fixed cutting assembly 7.

[0141] During the rotation of the rotating frame 62 relative to the fixed frame 63, the rotating shaft 421 drives the crankshaft 422 to shift relative to the functional plate 41. During the movement of the crankshaft 422, the engaging part 427 can separate from the limiting slot 412, allowing the rotating frame 62 to be in a free state. By adjusting the angle between the rotating frame 62 and the fixed frame 63, the distance between the guide wheel 2 and the surface to be cut 200 can be adjusted, thereby adjusting the cutting depth of the fixed cutting assembly 7. When the appropriate depth is reached, the engaging part 427 can engage with the limiting slot 412, thus fixing the cutting depth and achieving convenient adjustment of the cutting depth.

[0142] Furthermore, the functional plate 41 also includes a limiting groove 413, through which the rotating shaft 421 passes and is fixed on the adjusting rod 621 of the rotating frame 62, and the moving path of the rotating shaft 421 is limited by the limiting groove 413.

[0143] Specifically, the limiting groove 413 is arc-shaped, and the center of the circle corresponding to the limiting groove 413 is the fixed rod 612. This arrangement allows the rotating shaft 421 to move within the moving path defined by the limiting groove 413 when the adjusting rod 621 rotates around the fixed rod 612.

[0144] The limiting part 411 is disposed below the limiting groove 413, and the curvature of the limiting part 411 matches the curvature of the limiting groove 413. This arrangement allows the engaging part 427 on the crankshaft 422 to separate from or engage with the limiting groove 412 on the limiting part 411 when the rotating shaft 421 moves within the movement path defined by the limiting groove 413. This adjusts the distance between the guide wheel 2 and the surface to be cut 200, thereby adjusting the cutting depth of the cutting assembly 7.

[0145] The extension direction of several limiting slots 412 is the same as the setting direction of the limiting slots 413, and the limiting slots 412 match the locking part 427, so that the locking part 427 can be accommodated in the limiting slots 412 to restrict the movement of the locking part 427.

[0146] In this embodiment, the extension direction of the limiting slot 412 is set at an acute angle with the surface to be cut 200, which improves the limiting strength between the locking part 427 and the limiting slot 412, further improving the stability of the locking and preventing the locking part 427 from falling out of the limiting slot 412 due to the vibration of the cutting guide carriage 10 during use. Of course, in other embodiments, the extension direction of the limiting slot 412 can also be set perpendicular to the surface to be cut 200, which is not limited here.

[0147] When it is necessary to adjust the cutting depth of the cutting assembly 7, an external force is applied to the crankshaft rod 422, causing the crankshaft rod 422 to rotate around the rotating shaft 421. At the same time, the locking part 427 moves out of the limiting groove 412, and the adjusting rod 621 is in a free state. The adjusting rod 621 is rotated to adjust the height between the guide wheel 2 and the surface to be cut, thereby adjusting the cutting depth of the cutting assembly 7. After the adjustment is completed, a reverse force is applied to the crankshaft rod 422 to lock the locking part 427 into the limiting groove 412 to fix the cutting depth.

[0148] Furthermore, the crankshaft rod 422 includes a drive end 423 and a locking end 426. The rotating shaft 421 is movably connected between the drive end 423 and the locking end 426, and the drive end 423 and the locking end 426 move in opposite directions about the rotating shaft 421. That is, the crankshaft rod 422 and the rotating shaft 421 form a seesaw-like structure. When the drive end 423 moves downward, the locking end 426 can move in the opposite direction (i.e., upward), and when the drive end 423 moves upward, the locking end 426 can move downward. With this configuration, the movement of the locking end 426 can be controlled by applying a force to the drive end 423, thereby enabling the locking portion 427 on the locking end 426 to engage or disengage from the limiting groove 412.

[0149] The snap-fit ​​portion 427 is provided on the side of the snap-fit ​​end 426 facing the function plate 41, so as to snap or separate from the limiting slot 412 on the limiting portion 411 to limit the fixed cutting depth.

[0150] A drive plate 424 is provided on the drive end 423, and the drive plate 424 is bent from the drive end 423 in a direction away from the functional plate 41. A drive hole 425 is provided on the drive plate 424, and the drive hole 425 is provided through the drive plate 424. By providing the drive plate 424 and the drive hole 425, the drive end 423 is connected to the movable part 432 on the rotating frame 62 to realize linkage control.

[0151] Furthermore, the rotating frame 62 is provided with a handle 431 and a movable member 432, the movable member 432 being movably connected to the handle 431 via a pivot 4321. The end of the movable member 432 away from the handle 431 can move closer to or further away from the handle 431. The movable member 432 includes an adjusting portion 4322 and a connecting portion 4323 located on both sides of the pivot 4321. The adjusting portion 4322 and the connecting portion 4323 move in opposite directions around the pivot 4321, forming a seesaw-like structure. When the adjusting portion 4322 approaches the handle 431 under external force, the connecting portion 4323 moves away from the handle 431; when the adjusting portion 4322 moves away from the handle 431, the connecting portion 4323 moves closer to the handle 431.

[0152] A connecting structure 44 is provided between the movable component 432 and the driving end 423. As the movable component 432 approaches the handle 431, the driving end 423 is driven to move towards the mounting bracket 61 through the connecting structure 44.

[0153] The adjustment part 4322 is positioned away from the grip 431. One end of the connecting structure 44 is fixedly connected to the connecting part 4323, and the other end is connected to the drive plate 424 on the drive end 423. When the adjustment part 4322 moves upward toward the grip 431, the connecting part 4323 presses the connecting structure 44 downward, and drives the drive end 423 to move toward the mounting bracket 61 through the connecting structure 44. That is, when the drive end 423 moves downward, the snap-fit ​​end 426 opposite to the drive end 423 moves upward, thereby allowing the snap-fit ​​part 427 to separate from the limiting slot 412, so as to facilitate the adjustment of the distance between the guide wheel 2 and the cutting surface 200. By setting the connecting structure 44, the crankshaft rod 422 can be controlled to rotate by operating the distance of the movable part 432 relative to the grip 431, which improves the convenience of driving and further realizes the convenient control of the cutting depth of the cutting assembly 7.

[0154] In this embodiment, the connecting structure 44 includes a housing 441 and a connecting line 442. The connecting line 442 is housed within the housing 441 to protect it. Specifically, one end of the connecting line 442 is connected to the connecting portion 4323 on the movable member 432, and the other end passes through the drive hole 425 and is fixedly connected to the drive end 423. In other embodiments, only the connecting line 442 may be present, without the housing 441. Alternatively, the connecting structure 44 may be a drive rod, which is pushed by the movable member 432 to drive the crankshaft rod 422 to rotate. As long as the purpose of driving the crankshaft rod 422 to rotate around the rotation axis 421 can be achieved, no limitation is imposed here.

[0155] Furthermore, the cutting depth adjustment assembly 4 also includes a reset member 46, which is disposed near the snap-fit ​​end 426 of the crankshaft 422 and configured to provide power for snapping the snap-fit ​​portion 427 into the limiting slot 412.

[0156] In this embodiment, the reset member 46 is a retaining ring. A first wiring portion 428 extends from the retaining end 426 of the crankshaft rod 422 away from the retaining portion 427. A sliding post 45 extends from the rotating frame 62 toward the functional plate 41. A second wiring portion 451 is provided on the side of the sliding post 45 away from the rotating frame 62. Both ends of the reset member 46 are fixedly connected to the first wiring portion 428 and the second wiring portion 451, respectively. A clearance groove 414 is provided on the functional plate 41, and the sliding post 45 passes through the clearance groove 414 so that the second wiring portion 451 connects to the reset member 46.

[0157] When the movable part 432 moves upward toward the grip 431, the connecting part 4323 presses downward toward the connecting structure 44, and drives the driving end 423 to move toward the mounting bracket 61 through the connecting structure 44. At this time, the snap-fit ​​end 426 opposite to the driving end 423 moves away from the limiting part 411, and the snap-fit ​​part 427 separates from the limiting slot 412. At this time, the first wiring part 428 moves away from the reset part 46 to stretch the reset part 46, so that the reset part 46 tends to stretch the first wiring part 428 toward the second wiring part 451. When the movable part 432 is released, the reset part 46 stretches the first wiring part 428 toward the second wiring part 451, thereby causing the snap-fit ​​end 426 to move toward the limiting part 411, and the snap-fit ​​part 427 snaps into the limiting slot 412 to achieve snap-fit ​​fixation. At the same time, the drive end 423 opposite to the snap-fit ​​end 426 pulls the movable part 432 downward, thereby causing the movable part 432 to move away from the grip 431 and return to its initial state.

[0158] Furthermore, the cutting depth adjustment component 4 also includes a scale 47 and an indicator 48. The scale 47 is disposed on the side of the function plate 41 opposite to the limiting part 411, and has several graduation lines. The indicator 48 is disposed on the rotating shaft 421 and points to the scale 47. This configuration allows the cutting depth to be displayed with graduations via the scale 47 and indicator 48, clearly showing the current cutting depth and facilitating user adjustment and observation of the desired cutting depth.

[0159] In summary, when it is necessary to adjust the cutting depth of the cutting assembly 7, an external force is applied to the movable part 432, and the movable part 432 moves toward the handle 431. Since the adjusting part 4322 and the connecting part 4323 form a seesaw structure through the rotating shaft 4321, when the adjusting part 4322 moves toward the handle 431, the connecting part 4323 moves away from the handle 431, thereby pushing the connecting structure 44 toward the driving end 423 of the crankshaft 422, pushing the driving end 423 toward the mounting bracket 61, that is, moving downward. The crankshaft 422 rotates around the rotating shaft 421, causing the locking part 427 on the locking end 426 to disengage from the limiting slot 412 and move upward. At this time, the first wiring part 428 stretches the reset part 46, causing the reset part 46 to generate a pulling force to restore the initial state, that is, a pulling force that pulls the locking end 426 downward. At this time, the rotating frame 62 is in a free state. Pushing the adjusting rod 621 causes the rotating shaft 421 to move along the extension direction of the limiting groove 413 under the constraint of the limiting groove 413. At the same time, the sliding column 45 where the second wiring part 451 is located moves in the relief groove 414 to adjust the distance between the guide wheel 2 and the surface to be cut 200, thereby adjusting the cutting depth of the cutting assembly 7. After adjusting to the specified cutting depth, the external force applied to the moving part 432 is released. At this time, the locking end 426 of the crankshaft rod 422 moves towards the surface to be cut 200 under the pulling force of the reset part 46, so that the locking part 427 is locked in the limiting groove 412 to fix the cutting depth of the cutting assembly 7, thus completing the adjustment of the cutting depth of the cutting assembly 7.

[0160] In summary, the cutting guide carriage 10 reduces the number of structural parts by placing the fixed frame 63 and the rotating frame 62 on both sides of the mounting bracket 61, with the fixed frame 63 fixedly connected to the mounting bracket 61 and the rotating frame 62 rotatably connected to the mounting bracket 61. Guide wheels 2 are also fixed on the rotating frame 62. This results in a compact overall structure that facilitates installation and transportation. Furthermore, the distance between the guide wheels 2 and the cutting surface 200 can be adjusted by adjusting the rotating frame 62, thereby adjusting the cutting depth of the cutting assembly 7. The directional adjustment component 1 allows for adjustment of the offset angle of the guide wheels 2, and the lateral adjustment component 5 adjusts the left and right displacement of the cutting assembly 7, ensuring the cutting guide carriage 10 travels in a straight line for linear cutting. By making both the fixed frame 63 and the rotating frame 62 detachable, packaging is minimized, facilitating transportation and installation.

[0161] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
