The grooving motor 18 is installed below the left side of the support plate 16, and the grooving saw blade 17 is installed on the output end of the grooving motor 18. In the process of repairing cracks in building walls, it is usually necessary to use drilling equipment and grooving equipment separately. The drilling and grooving functions are integrated into one by the provided drilling and grooving mechanism 1, and then the drilling and grooving functions are simultaneously provided, thereby reducing the number of equipment required in the repair process, reducing the repair cost, and improving work efficiency.

When the transmission chain 72 moves, it will pull the slide plate 77 to move along the slide 71, thereby realizing the horizontal adjustment of the drilling and slotting mechanism 1. A handle 75 is fixed at the front end of the right rotating shaft 74.

[0033] Slide sleeves 78 are embedded on both the front and rear sides of the two sets of slide plates 77. Two sets of slide bars 76 are arranged inside the machine base 4. The two sets of slide bars 76 are respectively arranged on the front and rear sides of the transmission chain 72, and the slide sleeves 78 are sleeved on the slide bars 76. The slide sleeves 78 embedded on the front and rear sides of the slide plate 77 provide additional support and guidance for the slide plate 77. The inner diameter of the slide sleeve 78 matches the outer diameter of the slide bar 76, ensuring that the slide plate 77 can remain stable and not easily deviate from the track when moving along the slide bar 76. The two sets of slide bars 76 arranged on the front and rear sides of the transmission chain 72 not only provide a track for the horizontal movement of the slide plate 77, but also limit the up and down and left and right shaking of the slide plate 77 by cooperating with the slide sleeve 78, thereby improving the stability of the entire horizontal adjustment mechanism 7. This design ensures that the drilling and grooving mechanism 1 can maintain stable and accurate movement during the horizontal adjustment process through the design combination of the slide sleeve 78 and the slide bar 76, and can effectively reduce the vibration and deviation of the mechanism, thereby ensuring the quality and efficiency of the crack repair work.
