[0055] Referring to Figures 1 to 19, the present invention discloses a cutting device 100 for cutting a surface 200 to be cut, specifically for cutting a concrete layer, cement layer, etc. laid on the surface 200 to be cut. Of course, it can also be used to cut materials such as tiles and stones, and the present invention is not limited to this.

[0056] In this embodiment, the cutting device 100 includes a cutting guide vehicle 10 and a cutting assembly 7 disposed on the cutting guide vehicle 10. The cutting guide vehicle 10 is used to install the cutting assembly 7 and drive the cutting assembly 7 to move relative to the cutting surface 200.

[0057] The cutting guide vehicle 10 includes a direction adjustment assembly 1, a travel assembly, a cutting depth adjustment assembly 4, a lateral adjustment assembly 5, and a frame 6. The frame 6 is used to mount and support the cutting guide vehicle 10 and provides a mounting base for the aforementioned components. The travel assembly is located on the side of the frame 6 near the surface 200 to be cut and includes guide wheels 2 and support wheels 3. The travel assembly enables the frame 6 to move across the surface 200 to be cut and provides support for the frame 6. The direction adjustment assembly 1 is used to adjust the offset angle of the guide wheel 2 relative to the frame 6, allowing the guide wheel 2 to deflect relative to the frame 6 to adjust the direction of movement of the cutting guide vehicle 10. The cutting depth adjustment assembly 4 is used to adjust the distance between the guide wheel 2 and the surface 200 to be cut, thereby adjusting the depth of the surface 200 cut by the cutting assembly 7. The lateral adjustment assembly 5 is used to fine-tune the cutting assembly 7 left and right, thereby ensuring that the cutting assembly 7 and the cutting guide vehicle 10 are parallel in their travel directions. Of course, in other embodiments, the cutting guide vehicle 10 may not include all of the aforementioned components, as long as it includes components that meet the objectives of the present invention.

[0058] The frame 6 includes a mounting bracket 61 and a fixing bracket 63 and a rotating bracket 62 arranged on both sides of the mounting bracket 61 .

[0059] The mounting bracket 61 provides support and installation foundation for the cutting guide vehicle 10. The mounting bracket 61 includes a base plate 611, a fixing rod 612, and a mounting shaft 613. Among them, the base plate 611 is arranged close to the surface to be cut 200 (for example, the ground) and is parallel to the surface to be cut 200 to improve the connection strength of the frame 6. The cutting assembly 7 is fixedly mounted on the base plate 611. Specifically, a fixing groove is provided on the base plate 611, and the bottom of the cutting assembly 7 is fixed in the fixing groove, so that the cutting assembly 7 is fixed on the base plate 611. The fixing groove can also be designed to be compatible with cutting assemblies 7 of different sizes. The two support wheels 3 are fixedly connected to the base plate 611 by the mounting shaft 613 to support the cutting guide vehicle 10 and facilitate its walking. One end of the fixing rod 612 is fixedly connected to the fixed frame 63, and the other end is rotatably connected to the rotating frame 62 and is detachably connected.

[0060] Furthermore, a fine-tuning structure 614 is provided on the mounting bracket 61 for adjusting the distance between the base plate 611 and the two support wheels 3, thereby changing the distance between the cutting assembly 7 and the two support wheels 3, thereby satisfying the cutting requirements of the cutting assembly 7 closer to the wall from both the left and right directions, thereby increasing the cutting range.

[0061] The fine-tuning structure 614 includes a fine-tuning bracket 6141 and a fixing nut 6142. The fine-tuning bracket 6141 is sleeved on the mounting shaft 613. The fine-tuning bracket 6141 includes two symmetrically arranged extension arms and a connecting arm arranged between the two extension arms. Both extension arms are sleeved on the mounting shaft 613, and a plurality of first mounting holes are provided on the connecting arm. The base plate 611 is also provided with a plurality of second mounting holes at positions corresponding to the plurality of first mounting holes. The fixing nut 6142 passes through any pair of the first mounting holes and the second mounting holes, thereby fixing the base plate 611 on the mounting shaft 613. When it is necessary to make the cutting assembly 7 closer to the left support wheel 3, the fine-tuning bracket 6141 is adjusted to make it close to the left support wheel 3, and fixed by the fixing nut 6142, so that the cutting assembly 7 can be made to cut the wall closer to the left side, and vice versa.

[0062] Furthermore, a fender 615 is provided on the mounting bracket 61. The end of the bottom plate 611 close to the cutting assembly 7 extends in a direction away from the cutting assembly 7 to form the fender 615. By providing the fender 615, dust and splash protection requirements when the cutting assembly 7 is in operation can be met.

[0063] 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 fixed assembly or welded body that does not move relative to each other. The rotating frame 62 is rotatably connected to the mounting bracket 61. This arrangement reduces the number of structural components of the cutting guide vehicle 10, making the overall structure compact and convenient for installation and transportation. Furthermore, the rotating frame 62 is capable of relative movement relative to the fixed frame 63, and the angle between the rotating frame 62 and the fixed frame 63 can be adjusted using the cutting depth adjustment assembly 4.

[0064] The fixed frame 63 extends rearward and upward from the mounting bracket 61, serving as the main handle assembly of the cutting guide vehicle 10, making it easier for the user to push and control the cutting assembly 7.

The guide rod 623 is fixedly connected to the guide wheel 2 to facilitate adjusting the distance between the guide wheel 2 and the surface to be cut 200 by adjusting the height of the guide rod 623 relative to the cutting surface 200, thereby adjusting the cutting depth of the cutting assembly 7.

[0068] The adjusting rod 621 is arranged at one end of the support rod 622 away from the guide rod 623 and is detachably connected to the support rod 622 to facilitate the detachable assembly of the rotating frame 62 with the connection between the adjusting rod 621 and the support rod 622 as the center, thereby minimizing the packaging of the cutting guide vehicle 10 and facilitating its transportation and installation.

[0069] Furthermore, a second adjusting knob 624 is provided at the connection between the adjusting rod 621 and the support rod 622. By setting the second adjusting knob 624, the adjusting rod 621 and the support rod 622 can be quickly disassembled and folded, which facilitates the rapid disassembly and installation of the cutting guide vehicle 10 and minimizes packaging.

[0070] In another embodiment, the adjustment rod 621 and the support rod 622 are pivotally connected, the adjustment rod 621 is provided with a third meshing portion, and the support rod 622 is provided with a fourth meshing portion, and the third meshing portion and the fourth meshing portion are meshed with each other via gears. With this arrangement, the angle between the adjustment rod 621 and the support rod 622 can be adjusted, thereby meeting the height requirements of the rotating frame 62 for users of different heights. In addition, the adjustment rod 621 and the support rod 622 are arranged to be pivotally connected, which also facilitates the rotation frame 62 to be rotated, folded, or disassembled and assembled around the connection between the adjustment rod 621 and the support rod 622, thereby minimizing the packaging of the cutting guide vehicle 10 and facilitating its transportation and installation. The third meshing portion and the fourth meshing portion have the same structure as the first meshing portion 6311 and the second meshing portion 6321, and in other embodiments, they may also be different.

[0071] Furthermore, a second adjustment knob 624 is provided at the connection between the adjustment rod 621 and the support rod 622. After the adjustment rod 621 and the support rod 622 are adjusted according to the user's height, the second adjustment knob 624 fixes the angle between the adjustment rod 621 and the support rod 622, thereby improving the stability of the connection between the adjustment rod 621 and the support rod 622. Furthermore, the provision of the second adjustment knob 624 also allows for the rapid folding of the adjustment rod 621 and the support rod 622, facilitating quick disassembly and installation of the cutting guide vehicle 10 and minimizing packaging.

[0072] The frame 6 is provided with a receiving space 65, in which the cutting assembly 7 and the water tank 9 are both received and connected to the frame 6.

When the crank connecting rod 641 is subjected to external force and rotates until the starting shaft 643 abuts the starting switch 74, the rebound member 646 is stretched. When the external force disappears, the crank connecting rod 641 rotates in the opposite direction under the action of the rebound member 646 to return to the initial position.

[0080] The starting device 64 further includes a starting assembly, which is mounted on the second handle 632 of the fixing 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 assembly drives the first end 644 to rotate, the second end 642 rotates in the opposite direction and abuts against the starting switch 74, thereby activating the cutting assembly 7.

[0081] The starting assembly includes a handle 647, a starter 648, and a starter wire 649. The handle 647 is provided at the end of the adjustment rod 621 and is fixedly connected to the adjustment rod 621. The starter 648 is connected to the handle 647 and can rotate relative to the handle 647. One end of the starter wire 649 is connected to the starter 648, and the other end is connected to the first end 644. When the starter 648 moves toward the handle 647, the starter wire 649 is pulled, and the crankshaft connecting rod 641 rotates about the fixed axis 645, thereby starting the cutting assembly 7. Preferably, the starter wire 649 is a brake wire, and the rebound member 646 is a torsion spring.

[0082] Of course, in this embodiment, a limiting device (not shown) can also be set 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 in a direction away from the handle 647, so that the start shaft 643 keeps pressing the start switch 74, so that the cutting assembly 7 continues to rotate. The specific structure and limiting method of the limiting device can be set according to actual conditions, and the limiting device can also be set to other positions, which is not limited here.

[0083] That is to say, when it is necessary to start the cutting assembly 7, an external force is applied to the starter 648 so that the starter 648 can move toward the handle 647, and then the crank connecting rod 641 is pulled through the start line 649, so that the crank connecting rod 641 rotates around the fixed axis 645, and at the same time the rebound member 646 is stretched until the start shaft 643 abuts against the start switch 74, so that the cutting assembly 7 rotates, and the external force applied to the starter 648 is cancelled. The crank connecting rod 641 returns to the initial position under the drive of the rebound member 646, so that the cutting assembly 7 stops rotating.

[0084] Please refer to FIG9 and combine it with FIG15 . Furthermore, an anti-self-locking structure 75 is provided on the rear handle 72 of the cutting assembly 7. The cutting guide vehicle 10 also includes a lateral adjustment assembly 5 provided on the side of the fixed frame 63 facing the rotating frame 62. The housing 532 of the lateral adjustment assembly 5 is interference-fitted with the anti-self-locking structure 75. When the lateral adjustment assembly 5 is installed on the fixed frame 63, the anti-self-locking structure 75 is in an unlocked state. This arrangement allows the lateral adjustment assembly 5 to be installed in place, while simultaneously depressing the anti-self-locking structure 75. This allows the anti-self-locking structure 75 to remain in the unlocked state. The cutting assembly 7 can be started for cutting by simply pressing the starter 648. This structure is convenient, as no other structure is required to depress the anti-self-locking structure 75.

[0085] Furthermore, the cutting guide vehicle 10 has a three-wheeled structure, with two support wheels 3 positioned behind the frame 6 and arranged in parallel. A guide wheel 2 is positioned in front of the frame 6, providing front guidance. The guide wheel 2 is mounted on the guide rod 623 of the rotating frame 62 and is positioned alongside the cutting assembly 7 at the bottom of the frame 6. This serves to adjust the distance between the cutting assembly 7 and the surface 200 to be cut. Adjusting the offset angle of the guide wheel 2 using the direction adjustment assembly 1 also adjusts the direction of movement of the cutting guide vehicle 10. Furthermore, the guide wheel 2 is spaced apart from the cutting assembly 7 to prevent the cutting assembly 7 from damaging the guide wheel 2 during operation.

[0086] Referring to Figures 1-3 and 14 , to enhance 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 comprises a fixed shaft mounted on the rotating frame 62 and a rotating handle rotatably connected to the fixed shaft. The rotating handle comprises a first handle and a second handle arranged at an angle. The first handle is intended for the user to grasp, while the second handle is intended to abut against the handle 71 of the cutting assembly 7, thereby enhancing the installation stability of the cutting assembly 7.

[0087] Furthermore, a metal spring is provided below the fixed rotating shaft, and a protrusion is provided on the metal spring. A first abutting groove and a second abutting groove are provided at the bottom and side of the first handle, respectively. When the first handle is pressed downward so that the second handle abuts against the handle 71, the first abutting groove engages with the protrusion, and at this time, the rotating handle is in a pressed and fixed state. When the first handle is pulled upward so that the second handle is separated from the handle 71, the second abutting groove engages with the protrusion, and at this time, the rotating handle is in a decompressed and released state. By providing the first abutting groove, the second abutting groove and the protrusion, the user can get feedback of sound and tactile feeling when pressing into place, which provides a better user experience.

[0088] Referring to Figures 1, 3, and 10-13, the direction adjustment assembly 1 is disposed 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 within the sleeve 15, with a portion exposed outside the sleeve 15 to be fixedly connected to the guide wheel 2. A first gap 141 is defined between the connecting shaft 11 and the sleeve 15. The bearing 12 is disposed 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 the axis. The limiting structure 16 is disposed on the sleeve 15 and passes through the sleeve 15 to abut against the connecting shaft 11 to fix the eccentric angle between the connecting shaft 11 and the sleeve 15.

[0089] By partially positioning the connecting shaft 11 within the sleeve 15 and connecting the other end to the guide wheel 2, the offset angle of the connecting shaft 11 relative to the sleeve 15 can be adjusted, thereby adjusting the offset angle of the guide wheel 2. Furthermore, the sleeve 15 is fixedly connected to the guide rod 623 of the frame 6. The connecting shaft 11 and the sleeve 15 connect the guide wheel 2 to the frame 6, supporting the frame 6 and adjusting the travel direction of the frame 6. By providing a bearing 12 and a stopper 16, the connecting shaft 11 can deflect within the sleeve 15 about the bearing 12, thereby adjusting the direction of the connecting shaft 11 relative to the sleeve 15. The stopper 16 cooperates with the connecting shaft 11 to fix the offset angle of the connecting shaft 11 relative to the bearing 12, improving the stability of the connection between the connecting shaft 11 and the sleeve 15 and enabling convenient adjustment of the travel direction of the guide wheel 2. This allows the support wheel 3 and the guide wheel 2 to maintain parallelism, enabling linear motion of the cutting guide vehicle 10, and locking them, thereby ensuring that the cutting guide vehicle 10 can travel in a straight line and cut.

[0090] Specifically, the guide rod 623 is fixedly connected to the sleeve 15 and is connected to the middle position of the sleeve 15. The sleeve 15 can be configured to 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 arranged in a direction parallel to the surface to be cut 200 and perpendicular to the direction of travel of the cutting guide vehicle 10. This arrangement allows the rotation direction of the guide wheel 2 to be parallel to the direction of travel of the cutting guide vehicle 10.

[0091] The sleeve 15 is cylindrical and hollow, and has a circular inner cavity 151 . The connecting shaft 11 is at least partially installed in the inner cavity 151 and can be offset in the inner cavity 151 .

[0092] The sleeve 15 is provided with a plurality of fixing holes 152 evenly distributed along the outer circumference of the sleeve. The fixing holes 152 and the fixing members 161 together form a limiting structure 16 to fix the connecting shaft 11 in the sleeve 15 through the limiting structure 16.

[0093] The connecting shaft 11 is cylindrical and includes a coaxial 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 that of the connecting section 112, which is larger than that of the free section 111.

[0094] The fixing 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 fixing section 113. That is, a first gap 141 is defined between the fixing section 113 and the inner wall of the sleeve 15. The provision of the first gap 141 facilitates installation of the connecting shaft 11 within the sleeve 15 and facilitates the use of external tooling to install the connecting shaft 11. This allows the connecting shaft 11 to remain in its initial position during assembly, thereby enabling the guide wheel 2 to be precisely positioned in the desired position during assembly.

[0095] A groove 114 is provided on the side of the fixing section 113 away from the connecting section 112. The groove 114 is formed inwardly from the outer surface of the fixing section 113 and is arranged corresponding to the fixing hole 152 on the sleeve 15. The fixing hole 152 passes through the sleeve 15 and is arranged opposite to 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 and abut against the bottom of the groove 114 to limit the distance between the connecting shaft 11 and the sleeve 15, thereby 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 provided on the stud. The stud abuts against the bottom of the groove 114. The fixing hole 152 is provided with an internal thread. The threaded connection between the stud and the fixing hole 152 can adjust the length of the stud extending into the sleeve 15, thereby adjusting the distance between the connecting shaft 11 and the sleeve 15. The groove 114 is provided in the shape of an annular groove, 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 .

[0096] The groove 114 is formed around the outer surface of the fixing section 113 of the connecting shaft 11. At least three retaining structures 16 are provided, and the at least three retaining structures 16 are evenly distributed along the outer circumference of the sleeve 15. In other words, there are at least three fixing holes 152 provided on the outer circumference of the sleeve 15, and the fixing holes 152 are evenly distributed on the sleeve 15 and correspond to the grooves 114.

[0097] Preferably, there are four fixing holes 152, and the four fixing holes 152 are evenly distributed on the outer peripheral surface of the sleeve 15, that is, in the diameter direction of the sleeve 15, the angle between two adjacent fixing holes 152 is 90°, and the two relatively arranged fixing holes 152 are arranged on the same straight line. Of course, in other embodiments, the fixing holes 152 can be set to three, in which case the angle between two adjacent fixing holes 152 is 120°, and the fixing holes 152 can also be set to five, six or other numbers, which are not limited here.

[0098] In this embodiment, the groove 114 is arranged in an annular shape on the outer surface of the connecting shaft 11. Such an arrangement enables the connecting shaft 11 to rotate in the sleeve 15, and no matter how much the rotation angle is, 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 devices, and the fixing hole 152 is set corresponding to the blind hole. The groove 114 may also not be set on the connecting shaft 11, and the fixing member 161 directly abuts against the outer wall surface of the connecting shaft 11. There is no restriction here.

[0099] 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 abutting member 121 and a rotating member 123.

[0100] The abutment member 121 abuts against the sleeve 15. An abutment groove 153 is provided in the sleeve 15. The abutment member 121 is received in the abutment groove 153 and is connected to the sleeve 15 by interference fit. Specifically, the connecting section 112 is arranged opposite to the abutment groove 153. The abutment groove 153 is formed by being recessed from the inner wall of the inner cavity 151 in a direction away from the connecting shaft 11. In other words, 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 and is connected to the sleeve 15 by interference fit to prevent the abutment member 121 from falling off the sleeve 15 during use and to prevent the abutment member 121 from rotating in the sleeve 15.

[0101] A rotation cavity 122 is defined in the abutting member 121 . The rotation member 123 is received in the rotation cavity 122 and is rotatable in the rotation cavity 122 , so that the connecting shaft 11 can deviate in the sleeve 15 with the rotation member 123 as the axis.

[0102] Furthermore, the rotating cavity 122 is arranged in an arc shape, and the rotating member 123 abuts the rotating cavity 122 and has an arc surface 125 facing the rotating cavity 122. The surface curvature of the rotating cavity 122 is smaller than the curvature of the arc surface 125, so that the rotating member 123 can rotate in any direction in the rotating cavity 122.

[0103] Specifically, the bearing 12 is provided with an axial hole 124, which passes through the rotating member 123 and the abutting member 121, so that the abutting member 121 and the rotating member 123 cannot form a complete spherical shape. In the direction perpendicular to the axial hole 124, the diameter of the rotating cavity 122 matches the maximum diameter of the rotating member 123 and is larger than the aperture of the axial hole 124, so that the rotating member 123 can rotate in the rotating cavity 122 but cannot pass through the axial hole 124, thereby restricting the rotating member 123 in the abutting member 121. Preferably, the bearing 12 is a spherical plain bearing 12.

[0104] The connecting section 112 on the connecting shaft 11 passes through the shaft hole 124 of the bearing 12. Specifically, the connecting section 112 is located in the middle of the connecting shaft 11, and the diameter of the connecting section 112 is smaller than the diameter of the fixed section 113. The size of the shaft hole 124 is the same as that of the connecting section 112, so that the connecting section 112 is received in the shaft hole 124 and abuts against the side wall of the shaft hole 124, thereby achieving the connection between the connecting shaft 11 and the rotating member 123. Furthermore, the connecting shaft 11 can drive the rotating member 123 to rotate within the rotating cavity 122, so that the connecting shaft 11 rotates around the bearing 12 as the axis. Preferably, the connecting section 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.

[0105] The connecting shaft 11 also includes a free section 111 that is not housed within the sleeve 15. The free section 111 extends into the guide wheel 2 and is connected to the guide wheel 2, allowing the guide wheel 2 to rotate about the connecting shaft 11 as the axis to achieve 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 sleeved on the outside of the free section 111. A fastener 18 is provided at the end of the free section 111 to confine the guide wheel 2 between the fastener 18 and the connecting section 112 to prevent 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, thereby improving the stability and precision of the connection between the guide wheel 2 and the connecting shaft 11.

[0106] Furthermore, the direction adjustment assembly 1 includes a sleeve 13, which is disposed between the sleeve 15 and the connecting shaft 11. Specifically, the sleeve 13 is located within a first gap 141, and a second gap 142 is defined between the sleeve 13 and the connecting shaft 11. The sleeve 13 and the sleeve 15 are connected by an interference fit or integrally formed. The sleeve 13 is annular, and the second gap 142 is no greater than 0.7 mm in the radial direction of the connecting shaft 11. Preferably, the second gap 142 is 0.5 mm.

[0107] Specifically, the abutment groove 153 and the fixing hole 152 are respectively arranged at both ends of the sleeve 15, the sleeve 13 is accommodated in the inner cavity 151 and is arranged between the abutment groove 153 and the fixing hole 152, and the sleeve 13 is arranged opposite to the fixed section 113 of the connecting shaft 11. By connecting the sleeve 13 and the sleeve 15 through interference fit, the sleeve 13 is prevented from rotating relative to the sleeve 15, thereby preventing the sleeve 13 from falling off.

[0108] By arranging a sleeve 13 in the sleeve 15 and setting a gap 14 between the sleeve 13 and the connecting shaft 11, on the one hand, it is used to limit the offset distance of the connecting shaft 11 in the sleeve 15. Specifically, the connecting shaft 11 is offset in 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 vehicle 10 is deflected during movement. When the connecting shaft 11 abuts against the sleeve 13, the maximum deflection angle of the guide wheel 2 is reached, so as to avoid the cutting guide vehicle 10 from deflecting too much and causing damage to the cutting assembly 7.

[0109] On the other hand, it is used to achieve precise positioning when assembling the connecting shaft 11 and the guide wheel 2. Specifically, when assembling the connecting shaft 11 and the guide wheel 2, an external tool is inserted between the connecting shaft 11 and the sleeve 13. That is, part of the external tool is inserted into the second gap 142 to fix the distance between the connecting shaft 11 and the sleeve 13, so that the connecting shaft 11 remains stable. Subsequently, the guide wheel 2 is assembled to 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, and the assembly accuracy is also improved. After the guide wheel 2 and the connecting shaft 11 are assembled, the external tool is removed.

[0110] The external tooling can be understood as a device with multiple wedge-shaped claws, which are arranged in a ring shape. The wedge-shaped claws 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 the external tooling, and it is not limited to this. As long as the device can fix the connecting shaft 11 relative to the sleeve 15, it can become an external tooling, and there is no restriction here.

[0111] In this embodiment, the displacement of the connecting shaft 11 is limited by providing a bushing 13, and the bushing 13 is connected to the sleeve 15 by interference fit. Of course, in other embodiments, the bushing 13 may not be provided, and the displacement 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 also be provided to 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.

[0112] The direction adjustment component 1 also includes an end cover 17 connected to the sleeve 15. The size of the end cover 17 matches the size of the inner cavity 151. The end cover 17 is arranged at the end of the sleeve 15 away from the guide wheel 2, and allows part of the end cover 17 to extend into the inner cavity 151. The inner cavity 151 is covered by the end cover 17, making the direction adjustment component 1 beautiful while preventing impurities from entering the inner cavity 151.

[0113] In summary, when the direction adjustment assembly 1 is connected to the guide wheel 2, an external tooling is used to be inserted into the second gap 142 to fix the connecting shaft 11 in the sleeve 15, and then the guide wheel 2 is fixed to the free section 111, and the guide wheel 2 is restricted to the outside of the free section 111 by the fixing member 161, and then the external tooling is removed. At this time, the connecting shaft 11 can be offset within the range of the sleeve 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 fixing members 161 are respectively passed through at least three fixing holes 152 and abutted 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 distance of at least three fixing members 161 extending into the sleeve 15 can be the same or different.

[0114] When the angle between the guide wheel 2 and the frame 6 needs to be adjusted, the fixing members 161 are rotated in different directions, with some of the fixing members 161 rotating away from the inner cavity 151 and other parts rotating toward the inner cavity 151, so that the connecting shaft 11 can be offset 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 members 161 of the limiting structure 16 are re-locked to adjust the angle of the guide wheel 2.

[0115] 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.

[0116] In order to prevent the guide wheel 2 from interfering with the cutting assembly 7 when it is offset relative to the frame 6, thereby accidentally damaging the guide wheel 2, the cutting guide vehicle 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.

[0117] Continuing to refer to Figures 1 to 5 , and in conjunction with Figures 14 to 16 , the fixed frame 63 and the rotating frame 62 are arranged horizontally. Specifically, they are offset from each other in a left-right direction perpendicular to the direction of movement of the cutting guide vehicle 10. Furthermore, the offset distance between the fixed frame 63 and the rotating frame 62 is fixed, meaning that there is a fixed spacing between the fixed frame 63 and the rotating frame 62 in the left-right direction. 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.

[0118] When the cutting device 100 is in the cutting process, the cutting assembly 7 is prone to deflect, resulting in the cutting assembly 7 and the cutting guide vehicle 10 being inconsistent in their running directions. In order to solve this problem, the fixed frame 63 of the present invention is provided with a lateral adjustment assembly 5 on the side facing the rotating frame 62. The lateral adjustment assembly 5 is arranged on the first handle 631 of the fixed frame 63 and is arranged perpendicular to the first handle 631. In addition, the lateral adjustment assembly 5 is fixedly connected to the rear handle 72 of the cutting assembly 7, thereby fixing the cutting assembly 7 to the fixed frame 63. By adjusting the lateral adjustment assembly 5, the left and right offset direction of the cutting assembly 7 on the cutting guide vehicle 10 is adjusted so that the cutting assembly 7 is parallel to the movement direction of the cutting guide vehicle 10, thereby allowing the cutting device 100 to run smoothly without being blocked or deflected.

[0119] The lateral adjustment assembly 5 includes a connecting rod 51 arranged on the fixing frame 63 , and a sliding structure 53 and an adjusting member 54 sleeved on the outside of the connecting rod 51 .

[0120] 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 .

[0121] The sliding structure 53 is provided with a sliding hole 531 for the connecting rod 51 to pass through. The sliding structure 53 is mounted on the outside of the connecting rod 51 through the sliding hole 531 and can slide along the connecting rod 51. In addition, the sliding structure 53 and the adjusting member 54 are rotatably engaged. The sliding structure 53 is also 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 fixing frame 63 is adjusted, thereby adjusting the left and right offset angle of the cutting assembly 7 on the cutting guide vehicle 10, so that the cutting assembly 7 can be parallel to the travel direction of the cutting guide vehicle 10.

[0122] 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 encloses a receiving cavity 556. An adjustment surface 552 is provided on the side of the receiving cavity 556 facing the adjusting member 54. The adjustment surface 552 has a height difference along the extension direction of the extension wall 551. This arrangement allows the adjustment block 542 on the adjusting member 54 to press against the sliding structure 53 using the height difference of the adjustment surface 552 when the adjusting member 54 is rotated, thereby allowing the sliding structure 53 to slide left and right along the extension direction of the connecting rod 51.

[0123] Furthermore, the lateral adjustment assembly 5 further includes an elastic member 52 , and the elastic member 52 is disposed between the fixing frame 63 and the sliding structure 53 .

[0124] In this embodiment, the elastic member 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 member 52 abuts the first handle 631, and the other end abuts the side wall of the sliding structure 53, thereby providing a force for the sliding structure 53 to move away from the first handle 631. When the adjustment member 54 rotates relative to the connecting rod 51 to press the adjustment surface 552 on the mating portion 55, the sliding structure 53 moves on the connecting rod 51 toward the first handle 631, thereby compressing the elastic member 52. At this time, the elastic member 52 has a tendency to push the sliding structure 53 away from the first handle 631.

[0125] Furthermore, a partition plate 557 is provided within the accommodating cavity 556 to separate the adjustment surface 552. The height of the adjustment surface 552 gradually increases from one side of the partition plate 557 to the other side (see Figure 4). That is, there is a maximum height difference between the two sides of the partition plate 557. Preferably, this maximum height difference is 1-2 mm. In other words, for each rotation of the adjustment member 54 on the adjustment surface 552, the sliding structure 53 moves a distance of 1-2 mm on the connecting rod 51.

[0126] The adjusting member 54 is fixedly mounted 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 received 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 of ​​the adjusting member 54 and improve the connection stability of the adjusting member 54.

[0127] The adjusting member 54 has a centrally located connecting rod hole 541 through which the adjusting member 54 is mounted and rotatable about the connecting rod 51. The connecting rod 51 has a locking member 511, one end of which is connected to the connecting rod 51 and the other end of which abuts against the adjusting member 54 to retain the adjusting member 54 on the connecting rod 51.

[0128] The adjustment member 54 includes an adjustment block 542 disposed toward the sliding structure 53. The adjustment block 542 protrudes outward from a side of the adjustment member 54 near the first handle 631. That is, the adjustment block 542 can extend into the accommodating cavity 556 and abut against the adjustment surface 552. When the adjustment member 54 is rotated, the adjustment block 542 moves along the adjustment surface 552, and the height difference of the adjustment surface 552 drives the sliding structure 53 to move left and right along the direction of the connecting rod 51.

[0129] Furthermore, in order to improve the connection stability between the adjustment surface 552 and the adjustment block 542, a first anti-slip portion 553 is provided on the side of the adjustment surface 552 facing the adjustment block 542, and a second anti-slip portion 543 that cooperates and engages with the first anti-slip portion 553 is provided on the side of the adjustment block 542 facing the adjustment surface 552.

[0130] In this embodiment, the first anti-slip portion 553 includes a plurality of radially arranged racks 554, with tooth grooves 555 provided between adjacent racks 554. The second anti-slip portion 543 includes adjacently arranged clamping blocks 5431 and clamping grooves 5432. The clamping blocks 5431 cooperate with the tooth grooves 555, and the clamping grooves 5432 cooperate with the racks 554. The clamping blocks 5431 and the clamping grooves 5432 respectively engage with the tooth grooves 555 and the racks 554 to improve the movement stability of the adjustment block 542 on the adjustment surface 552. At the same time, by providing a plurality of radially arranged racks 554 on the adjustment surface 552, the rotation angle of the adjustment member 54 relative to the sliding structure 53 can be made more precise, thereby more accurately adjusting the sliding distance of the sliding structure 53 on the connecting rod 51, thereby precisely controlling the distance of the cutting assembly 7 relative to the guide wheel 2. Of course, in other embodiments, a tooth groove 555 may be provided only on the adjustment surface 552 and a clamping block 5431 may be provided on the adjustment block 542, or a rack 554 may be provided on the adjustment surface 552 and a clamping groove 5432 may be provided on the adjustment block 542 to precisely control the rotation of the adjustment member 54 relative to the sliding structure 53, and no limitation is made here.

[0131] Furthermore, a guide surface and a top surface are provided on the rack 554. 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 block 5431 on the adjustment block 542 can move along the guide surface toward the top surface, slide over the top surface to be accommodated in the tooth groove 555, and make the top surface contact with the bottom of the groove 5432 to limit the rotation angle of the adjustment member 54 relative to the matching part 55. By setting the guide surface to guide the movement of the block 5431, the resistance encountered by the adjustment member 54 during rotation is reduced, and the convenience of the adjustment member 54 in adjusting the sliding structure 53 is improved.

[0132] A positioning groove 558 is provided on the side of the extension wall 551 facing away from the accommodating 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 centered, meaning that the elastic member 52 is in a semi-compressed state. In this position, the sliding structure 53 can move both toward the fixed frame 63 and away from the fixed frame 63 under the push of the adjusting member 54. The positioning groove 558 and the positioning mark 545 make the distance between the adjusting member 54 and the sliding structure 53 visually visible, improving the user experience.

[0133] Furthermore, the adjusting member 54 is provided with at least two adjusting blocks 542, and the at least two adjusting blocks 542 are arranged in a circumference. In this embodiment, the adjusting member 54 is provided with three adjusting blocks 542, and the three adjusting blocks 542 are all arc-shaped to achieve stable support.

[0134] The outer wall of the adjusting member 54 is further provided with an operating portion 546. The operating portion 546 is recessed inward from the outer wall of the adjusting member 54 to facilitate the user's grip, thereby increasing the friction between the user and the adjusting member 54 to prevent the user from slipping when adjusting the adjusting member 54.

[0135] In general, when the cutting assembly 7 deviates from the forward direction of the cutting guide vehicle 10, the left-right displacement of the cutting assembly 7 can be fine-tuned using the adjustment member 54 and the sliding structure 53 to ensure that the cutting assembly 7 is parallel to the forward direction of the cutting guide vehicle 10 and to ensure the cutting effect. For example, by rotating the adjustment member 54, the adjustment block 542 can slide on the adjustment surface 552. The adjustment block 542 squeezes the sliding structure 53 on the connecting rod 51 toward the first handle 631, while compressing the elastic member 52. When the adjustment distance is reached, the locking block 5431 on the adjustment block 542 engages with the tooth groove 555 on the adjustment surface 552, thereby fixing the sliding structure 53 at that distance. When it is necessary to adjust the sliding structure 53 in the opposite direction, the adjusting member 54 is rotated in the opposite direction, and 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, and then fine-tune the left and right positions of the cutting assembly 7, so that the cutting assembly 7 is parallel to the movement direction of the cutting guide vehicle 10, so that the cutting device 100 can run smoothly without obstruction or deviation.

[0136] 1 to 5 in conjunction with FIG. 17 to 20 , the cutting depth adjustment assembly 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. Furthermore, the height of the guide wheel 2 relative to the surface to be cut 200 can also be adjusted, thereby adjusting the cutting depth of the cutting assembly 7.

[0137] The cutting depth adjustment assembly 4 includes a functional plate 41 and an adjustment structure 42. The functional plate 41 is arranged on a fixed frame 63 and is fixedly connected to the mounting bracket 61. The setting direction of the functional plate 41 is perpendicular to the setting direction of the mounting bracket 61, and the setting direction of the functional plate 41 is parallel to the rotating frame 62, so that the rotating frame 62 will not interfere with the functional plate 41 when rotating. The adjustment structure 42 is fixedly connected to the rotating frame 62 and is fixedly connected 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 the adjustment structure 42 can cooperate with the functional plate 41 to limit the rotation angle of the rotating frame 62 relative to the fixed frame 63, and at the same time, limit 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.

[0138] The function plate 41 includes a limiting portion 411, which is equipped with a plurality of spaced limiting teeth. Limiting slots 412 are formed between adjacent limiting teeth. Specifically, the limiting portion 411 is provided with a plurality of spaced limiting slots 412. These slots 412 are designed to engage with the engaging portion 427 on the adjustment 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 slots 412 can be adjusted according to user needs, thereby varying the cutting depth by changing the gear position.

[0139] The adjustment structure 42 includes a rotating shaft 421 and a crank rod 422. The rotating shaft 421 is fixed to the adjustment rod 621 of the rotating frame 62, and the crank rod 422 is movably connected to the rotating shaft 421. The end of the rotating shaft 421 away from the adjustment rod 621 is movably connected to the middle part of the crank rod 422, so that the crank rod 422 can rotate around the rotating shaft 421 to form a seesaw-like structure. The crank rod 422 is provided with a clamping portion 427 on the side facing the limiting portion 411, and the clamping portion 427 is used to clamp 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.

[0140] During the rotation of the rotating frame 62 relative to the fixed frame 63, the rotating shaft 421 drives the crankshaft rod 422 to move relative to the functional plate 41. Moreover, during the movement of the crankshaft rod 422, the engaging portion 427 can be separated from the limiting slot 412, so that the rotating frame 62 is 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 adjusted, the engaging portion 427 can engage with the limiting slot 412, thereby fixing the cutting depth and achieving convenient adjustment of the cutting depth.

[0141] Furthermore, the function board 41 further includes a limiting slot 413 , and the rotating shaft 421 passes through the limiting slot 413 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 slot 413 .

[0142] 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. Such an arrangement enables when the adjusting rod 621 rotates around the fixed rod 612, it can drive the rotating shaft 421 to move within the moving path defined by the limiting groove 413.

[0143] The limiting portion 411 is disposed below the limiting slot 413, and the curvature of the limiting portion 411 matches the curvature of the limiting slot 413. This configuration allows the engaging portion 427 on the crankshaft rod 422 to separate from or engage with the limiting slot 412 on the limiting portion 411 when the rotating shaft 421 moves within the movement path defined by the limiting slot 413, thereby adjusting the distance between the guide wheel 2 and the surface to be cut 200, and thereby adjusting the cutting depth of the cutting assembly 7.

[0144] The extending direction of the plurality of limiting slots 412 is the same as the setting direction of the limiting slots 413 , and the limiting slots 412 match the engaging portion 427 , so that the engaging portion 427 can be accommodated in the limiting slots 412 to limit the movement of the engaging portion 427 .

[0145] In this embodiment, the extension direction of the limiting slot 412 is set at an acute angle to the surface to be cut 200, which improves the limiting strength of the clamping portion 427 and the limiting slot 412, further improves the stability of the clamping, and avoids the clamping portion 427 falling off from the limiting slot 412 due to the vibration of the cutting guide vehicle 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.

[0146] When it is necessary to adjust the cutting depth of the cutting assembly 7, an external force is applied to the crankshaft rod 422 to make the crankshaft rod 422 rotate around the rotating shaft 421. At the same time, the clamping portion 427 is moved out of the limiting slot 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 clamp the clamping portion 427 into the limiting slot 412 to fix the cutting depth.

[0147] Furthermore, the crankshaft rod 422 includes a driving end 423 and a clamping end 426. The rotating shaft 421 is movably connected between the driving end 423 and the clamping end 426, and the driving end 423 and the clamping end 426 move in opposite directions with the rotating shaft 421 as the center. In other words, the crankshaft rod 422 and the rotating shaft 421 form a structure similar to a "seesaw". When the driving end 423 moves downward, the clamping end 426 can move in the opposite direction (i.e., upward), and when the driving end 423 moves upward, the clamping end 426 can move downward. With this arrangement, a force can be applied to the driving end 423 to control the movement of the clamping end 426, thereby achieving the clamping or separation of the clamping portion 427 on the clamping end 426 and the limit slot 412.

[0148] The clamping portion 427 is provided on a side of the clamping end 426 facing the functional board 41 to be clamped with or separated from the limiting clamping groove 412 on the limiting portion 411 to limit a fixed cutting depth.

[0149] A drive plate 424 is provided on the drive end 423. The drive plate 424 is bent away from the function plate 41. A drive hole 425 is provided on the drive plate 424 and extends through the drive plate 424. The drive plate 424 and the drive hole 425 connect the drive end 423 to the movable member 432 on the rotating frame 62, achieving coordinated control.

[0150] Furthermore, the rotating frame 62 is provided with a handle 431 and a movable member 432, and the movable member 432 is movably connected to the handle 431 via a rotating shaft 4321. The end of the movable member 432 away from the handle 431 can move closer to or farther away from the handle 431. The movable member 432 includes an adjustment portion 4322 and a connecting portion 4323 located on both sides of the rotating shaft 4321. The adjustment portion 4322 and the connecting portion 4323 move in opposite directions with the rotating shaft 4321 as the center, forming a "seesaw"-like structure. When the adjustment portion 4322 approaches the handle 431 under the action of an external force, the connecting portion 4323 moves away from the handle 431. When the adjustment portion 4322 moves away from the handle 431, the connecting portion 4323 moves toward the handle 431.

[0151] A connecting structure 44 is provided between the movable member 432 and the driving end 423 . When the movable member 432 approaches the handle 431 , the driving end 423 is driven to move toward the mounting bracket 61 by the connecting structure 44 .

[0152] The adjustment portion 4322 is positioned away from the handle 431. One end of the connecting structure 44 is fixedly connected to the connecting portion 4323, and the other end is connected to the drive plate 424 on the driving end 423. When the adjustment portion 4322 moves upward toward the handle 431, the connecting portion 4323 presses the connecting structure 44 downward, driving the driving end 423 toward the mounting bracket 61 through the connecting structure 44. Specifically, as the driving end 423 moves downward, the engaging end 426 opposite the driving end 423 moves upward, allowing the engaging portion 427 to disengage from the limiting slot 412, facilitating adjustment of the distance between the guide wheel 2 and the cutting surface 200. The provision of the connecting structure 44 allows the rotation of the crankshaft 422 to be controlled by adjusting the distance between the movable member 432 and the handle 431, improving actuation convenience and further enabling convenient adjustment of the cutting depth of the cutting assembly 7.

[0153] In this embodiment, the connecting structure 44 includes a shell 441 and a connecting wire 442, and the connecting wire 442 is housed in the shell 441 to protect the connecting wire 442. Specifically, one end of the connecting wire 442 is connected to the connecting portion 4323 on the movable member 432, and the other end is fixedly connected to the driving end 423 through the driving hole 425. An external force is applied to the movable member 432, so that the movable member 432 moves toward the handle 431, and then the connecting wire 442 is pulled to move in the shell 441, so that the shell 441 pushes the drive plate 424 to move, so that the crankshaft rod 422 rotates around the rotating shaft 421. In other embodiments, there may be only a connecting wire 442 without providing a shell 441, or the connecting structure 44 may be a driving rod, which is pushed by the movable member 432 so that the driving rod pushes the crankshaft rod 422 to rotate. As long as the purpose of driving the crankshaft rod 422 to rotate around the rotating shaft 421 can be achieved, there is no limitation here.

[0154] Furthermore, the cutting depth adjustment assembly 4 further includes a reset member 46 , which is disposed near the clamping end 426 of the crankshaft rod 422 and configured to provide power to enable the clamping portion 427 to be clamped to the limiting clamping slot 412 .

[0155] In this embodiment, the reset member 46 is a retaining spring. The clamping end 426 of the crankshaft rod 422 extends a first connection portion 428 in a direction away from the clamping portion 427. The rotating frame 62 extends a sliding column 45 in the direction of the functional board 41. A second connection portion 451 is provided on the side of the sliding column 45 away from the rotating frame 62. The two ends of the reset member 46 are fixedly connected to the first connection portion 428 and the second connection portion 451 respectively. A clearance groove 414 is provided on the functional board 41. The sliding column 45 passes through the clearance groove 414 so that the second connection portion 451 is connected to the reset member 46. Please refer to Figures 21 and 22. In one embodiment, the clearance groove 414 is arranged in an arc shape. The sliding column 45 is received in the clearance groove 414 and can slide along the clearance groove. The clearance groove 414 takes the fixed rod 612 as the center of the circle. Please refer to FIG. 4 and FIG. 18 . In another embodiment, the shape of the clearance groove 414 is not limited. The clearance groove 414 only needs to allow the sliding post 45 to pass through without interfering with the sliding of the sliding post 45 , as shown in FIG. 4 and FIG. 18 , to reduce weight.

[0156] When the movable member 432 moves upwardly toward the handle 431, the connecting portion 4323 presses the connecting structure 44 downwardly, and through the connecting structure 44, the driving end 423 moves toward the mounting bracket 61. At this time, the clamping end 426 opposite the driving end 423 moves away from the limiting portion 411, and the clamping portion 427 separates from the limiting slot 412. At this time, the first connecting portion 428 moves away from the reset member 46 to stretch the reset member 46, causing the reset member 46 to tend to pull the first connecting portion 428 toward the second connecting portion 451. When the movable member 432 is released, the reset member 46 pulls the first connecting portion 428 toward the second connecting portion 451, causing the clamping end 426 to move toward the limiting portion 411, and the clamping portion 427 engages with the limiting slot 412, achieving a clamped and fixed connection. At the same time, the driving end 423 opposite to the clamping end 426 pulls the movable member 432 downward, so that the movable member 432 moves away from the handle 431 and returns to the initial state.

[0157] Specifically, a first wiring groove is provided on the first wiring portion 428, and a second wiring groove is provided on the second wiring portion 451. The reset member 46 is a tension spring, and the two ends of the tension spring are respectively arranged in the first wiring groove 429 and the second wiring groove 452 to drive the first wiring portion 428 to move toward the second wiring portion 451.

[0158] Furthermore, the cutting depth adjustment assembly 4 also includes a scale 47 and an indicator 48. The scale 47 is disposed on the side of the function plate 41 facing away from the stopper 411 and is provided with a plurality of scale lines. The indicator 48 is disposed on the rotation shaft 421 and points toward the scale 47. This arrangement allows the cutting depth to be displayed on a scale using the scale 47 and indicator 48, allowing the current cutting depth to be clearly visible, making it easier for the user to adjust and observe the desired cutting depth value.

[0159] In summary, when the cutting depth of the cutting assembly 7 needs to be adjusted, external force is applied to the movable part 432, and the movable part 432 moves toward the handle 431. Since the adjusting portion 4322 and the connecting portion 4323 form a seesaw structure through the rotating shaft 4321, when the adjusting portion 4322 moves in the direction close to the handle 431, the connecting portion 4323 moves in the direction away from the handle 431, and then pushes the connecting structure 44 toward the driving end 423 of the crankshaft rod 422, pushing the driving end 423 to move in the direction close to the mounting bracket 61, that is, moving downward, and the crankshaft rod 422 rotates around the rotating shaft 421, so that the clamping portion 427 on the clamping end 426 disengages from the limiting slot 412 and moves upward. At this time, the first wiring portion 428 stretches the reset member 46, so that the reset member 46 generates a pulling force to restore the initial state, that is, the pulling force to pull the clamping end 426 downward. At this point, the rotating frame 62 is in a free state. Pushing the adjustment rod 621 causes the rotating shaft 421 to move along the extension direction of the limiting groove 413 under the restriction of the limiting groove 413. Simultaneously, the sliding post 45, where the second connecting portion 451 is located, moves within the clearance groove 414 to adjust the angle between the rotating frame 62 and the fixed frame 63. Simultaneously, the distance between the guide wheel 2 and the surface to be cut 200 is adjusted, thereby adjusting the cutting depth of the cutting assembly 7. When the desired cutting depth is reached, the external force applied to the movable member 432 is removed. At this point, the engaging end 426 of the crankshaft rod 422, under the pulling force of the reset member 46, moves toward the surface to be cut 200, causing the engaging portion 427 to engage within the limiting groove 412, thereby fixing the angle between the rotating frame 62 and the fixed frame 63 and further fixing the cutting depth of the cutting assembly 7, thereby completing the adjustment of the cutting depth of the cutting assembly 7.

[0160] In summary, the cutting guide vehicle 10 is constructed by arranging a fixed frame 63 and a rotating frame 62 on either side of a 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. A guide wheel 2 is also fixed to the rotating frame 62, thereby reducing the number of structural components of the cutting guide vehicle 10, making the overall structure compact and convenient for installation and transportation. Furthermore, the rotating frame 62 can be adjusted to adjust the distance of the guide wheel 2 relative to the cutting surface 200, thereby adjusting the cutting depth of the cutting assembly 7. A direction adjustment assembly 1 is provided to facilitate adjustment of the offset angle of the guide wheel 2, and a lateral adjustment assembly 5 is provided to adjust the left and right displacement of the cutting assembly 7, allowing the cutting guide vehicle 10 to operate in a straight line, thereby achieving the purpose of straight-line cutting. By configuring both the fixed frame 63 and the rotating frame 62 as detachable structures, packaging is minimized, facilitating transportation and installation.
