Description

Technical Field

[0001] This invention relates to the field of auxiliary tools for interior decoration, and specifically to a wall grooving device for interior decoration. Background Technology

[0002] Interior decoration encompasses room design, renovation, furniture arrangement, and various small embellishments. It focuses on the interior construction of a building, including not only the design and construction phases but also the ongoing decoration after moving in. The more materials and the more complex the materials used in interior decoration, the more pollutants are likely to be generated. Generally, new homes are typically unfinished, with only door frames and no doors, and the walls and floors only have basic treatment without surface finishing. When renovating an unfinished home, it's often necessary to cut grooves in the walls to accommodate electrical wiring and light switches / sockets.

[0003] The existing plumbing and electrical wiring typically uses plumbing and electrical grooving machines. However, when creating grooves for electrical boxes and power strips, impact drills are usually used because the grooves have a certain depth. Using impact drills not only generates severe vibrations but also has a huge destructive force, which can easily damage the wall. Furthermore, during the impact drill grooving process, operators need to manually clean the debris in the groove to observe its depth. Therefore, we propose a wall grooving device for interior decoration. Summary of the Invention

[0041] Refer to the instruction manual appendix Figure 1-8When using the device, first hold the handle 25 and turn on the power switch on the handle 25. The power switch is connected to the socket via a plug. The power switch controls the rotation speed and operating power of the motor 14. When grooving is required during interior decoration, align one end of the telescopic housing 2 with the grooving path and align the two chain assemblies 8 with the grooving path. Start the motor 14 using the power switch on the handle 25. The output shaft of the motor 14 drives the drive gear 15 to rotate, which in turn drives the first driven gear 12 to rotate. 2 drives the second driven gear disk 11 to rotate.
