Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a handheld wall cutter. Background Art

[0002] During the construction process, if a house needs to be renovated or remodeled, a cutting machine is needed to cut holes in the wall to meet the needs of the construction. The existing cutting machine is generally fixed on a support frame, and the support frame drives the cutting assembly to move in the vertical direction through a lifting mechanism to complete the cutting. The existing cutting machine has a large structure and is relatively bulky. It is very laborious to transport and operate, and is inconvenient to use. In addition, a large amount of dust is generated during the cutting process, and the dust cannot be removed in time, resulting in a bad working environment for the construction workers and affecting their health. For example, the authorization announcement number CN20451086 3U's Chinese patent document records a portable electric wall cutter, which includes a guide rail rod and a rack arranged on one side of the guide rail rod, as well as a base, a lifter, and a cutting saw disk. A cutting motor is fixedly connected to the lifter, and the output shaft end of the cutting motor is fixedly connected to the cutting saw disk. The building is cut by controlling the lifting and lowering of the saw disk to carry out renovation, maintenance and other project engineering. The patented cutting machine has a large structure and is relatively bulky. It is very laborious to transport and operate and is inconvenient to use. In addition, a large amount of dust is generated during the cutting process, and the dust cannot be removed in time, resulting in a poor working environment for construction workers and affecting their health.
