[0027] When it is necessary to groove the wall, the staff pushes the device in front of the wall where the grooves are required, and then adjusts it according to the position of the line drawn on the wall. When it is necessary to adjust the height, the first motor 54 can be controlled to work, and the first motor 54 drives the first screw rod 52 to rotate, and then the first nut 53 drives the movable plate 4 to move upward, and then all the components on the movable plate 4 move upward together. When the groover 810 is at the top position of the marking, the first motor 54 is controlled to stop working, and then the device is moved to adjust the groover 810 to align with the marking position. If the height is adjusted If it is not enough, the auxiliary lifting component 7 can be started, and then the second motor 76 is driven by the pulley and the flat belt, the second screw 74 rotates, and the second nut 73 drives the sliding block 72 to move upward along the U-shaped guide frame 71, thereby driving the cutting component 8 to further rise. When it reaches the marking height, the staff starts the slotting machine 810 and controls the third motor 88 to work at the same time. The third motor 88 drives the worm 83 to rotate. Due to the transmission of the second belt transmission component 87, the two worms 83 rotate synchronously, thereby driving the worm wheel 86 to rotate, and the fixing component 89 drives the slotting The machine 810 rotates, and the depth of the groove required in the wall can be adjusted. Then the third motor 88 is controlled to stop rotating, and then the second motor 76 is controlled to reverse, and the auxiliary lifting assembly 7 drives the cutting assembly 8 to move downward. When the auxiliary lifting assembly 7 moves to the lowermost side, the second motor 76 is controlled to stop moving. The staff controls the first motor 54 to rotate in the opposite direction, thereby being able to drive the cutting assembly 8 to continue to move downward. The slotting machine 810 moves downward to perform the slotting operation. When it is necessary to cut at an inclined angle, the staff controls one of the electric push rods 65 to extend, and then the first mounting plate 64 swings, and all components on the first mounting plate 64 are synchronously tilted. Since the electric push rod 65 is vertically arranged, when the first mounting plate 64 is tilted, the angles of the U-shaped slide 67 and the U-shaped seat 68 change, and the U-shaped slide 67 slides a corresponding distance along the straight slide rail 66. The device has a simple structure and can stably adjust the height of the slotting machine 810. It can be adjusted multiple times according to the actual height. It is also convenient to adjust the angle, can stably perform the slotting operation, and reduce the labor intensity of manual labor.

[0028] Embodiment 2: Based on embodiment 1, Figure 1 As shown, it also includes a guide sleeve 9, a guide rod 10, a U-shaped baffle 11 and a round shaft 12.

The guide rods 10 are slidably arranged in the guide sleeves 9. A U-shaped baffle 11 is arranged between the tops of the two guide rods 10 on the same side. The front and rear side walls of the U-shaped baffle 11 are both horizontally opened with a straight hole. The middle parts of the front and rear side walls of the U-shaped guide frame 71 are both provided with a round shaft 12. The straight hole of the U-shaped baffle 11 is slidably matched with the adjacent round shaft 12.

[0029] When the main lifting assembly 5 is lifted and lowered, the round shaft 12 on the U-shaped guide frame 71 will drive the U-shaped baffle frame 11 to move upward, and then drive the guide rod 10 to move upward synchronously. When the swing assembly 6 is adjusted, due to the inclination of the two U-shaped guide frames 71, the heights of the round shaft 12 are different. The round shaft 12 slides in the straight hole of the U-shaped baffle frame 11, which can drive the U-shaped baffle frame 11 and the guide rod 10 to slide up and down accordingly. The cooperation of the guide rod 10, the U-shaped baffle frame 11 and the round shaft 12 can further stabilize the auxiliary lifting assembly 7 and the cutting assembly 8 to prevent shaking during cutting.

[0030] like Figure 1 and Figure 6 As shown, it also includes a third mounting plate 13, a bracket 14, a guide wheel 15, a guide bar 16, a weight 17 and a pull rope 18. The third mounting plate 13 is arranged between the tops of the two U-shaped guide frames 71. The bracket 14 is symmetrically and tiltedly arranged on the top of the third mounting plate 13. The guide wheels 15 are rotatably arranged at both the front and rear ends of the bracket 14. The guide bars 16 are vertically arranged on the rear side walls of the U-shaped guide frames 71. The weight 17 is slidably arranged on the guide bars 16. The pull rope 18 is arranged on the weight 17. The pull rope 18 bypasses the two adjacent guide wheels 15 and is connected to the mounting card plate 891.
