[0002] During renovations of existing buildings, wall grooving is a common practice for electrical installation, pipe laying, and wall renovations. It's a routine construction procedure. Wall grooving involves cutting grooves in the wall to accommodate electrical wiring or pipes, and these are typically created using a grooving machine.

A support frame is fixedly connected to one side of the driving motor, and a shoulder strap for construction workers to carry is provided on the side of the support frame facing away from the driving motor. A transmission assembly for enabling the cutting assembly to cut is provided between the cutting assembly and the connecting rod. A dust cover is provided on the side of the connecting rod facing the cutting assembly, and an adjustable baffle is provided on the side of the dust cover facing the cutting assembly.

This allows for flexible operation. However, due to the use of a backpack-style handheld grooving machine, cutting vibrations and unstable grip make it difficult to control the depth and direction of the groove, reducing grooving quality.

[0033] When in use, the track frame 101 can be horizontally laid and installed close to the wall area, and the track wheel seat 13 of the grooving device is inserted into the track groove of the track frame 101. The speed, direction and stroke of the driver one, driver two and driver three are set by the industrial computer, so that the cutting blade 4 can be not limited to longitudinal and transverse cutting, and non-directional grooving can be achieved; and the power supply of the first motor 3 is turned on, and the cutting depth adjustment component is adjusted until the depth of the cutting blade 4 into the wall meets the requirements, and the cutting depth adjustment component is stopped to meet the cutting depth adjustment at any time during the grooving process.

[0034] By setting the adjustment component 2, the tangential direction and cutting height of the cutting blade 4 can be adjusted, and by cooperating with the sliding support component, the grooving depth and grooving direction during the non-directional grooving process are stabilized to ensure the grooving quality.
