Description

Technical Field

[0001] The utility model relates to the technical field of cutting equipment, in particular to a ground grooving and cutting device. Background Art

[0002] Cutting equipment is often needed at interior decoration or construction sites. Cutting equipment is used to make grooves of a certain thickness in the ground. Grooving is an architectural term, also called concealed wiring. The opened grooves are used to bury wires or water pipes inside to achieve the effect of burying wires, making the overall ground look more beautiful.

[0003] Existing cutting equipment mostly uses a handheld body when grooving the ground, and then uses the transmission mechanism inside the body to drive the saw blade to cut the ground, so that the ground gradually forms a groove in which electric wires or water pipes can be buried. However, since the depth of the groove needs to be controlled when grooving the ground, and currently the staff mostly measures the depth of the groove while grooving, it may cause the depth of the groove to exceed the predetermined depth when grooving, which may easily cause the height inside the groove to be uneven, thus affecting the construction quality.
