Description

Technical Field

[0001] The utility model relates to the field of house decoration tools, in particular to an indoor roof drilling auxiliary device. Background Art

[0002] At present, house decoration often requires installation of expansion screws on indoor roofs to fix suspended ceilings, chandeliers and other related decorative accessories; before installing the expansion screws, an installation hole needs to be drilled on the indoor roof; due to the high height of the indoor roof, construction workers usually need to stand on a stepladder or scaffolding, stand on the side of the installation hole and use an electric drill (or electric hammer) to drill upwards, which is inconvenient for observation and inconvenient for applying vertical upward force to the hole, and it is easy to cause tilting, making it difficult to ensure the quality of the hole, and it is not safe for the construction workers. The utility model of Chinese patent application No. 201922405839.4 relates to an indoor decoration ceiling drilling device, comprising a platform with multiple legs hinged on the platform, a vertical sleeve fixed in the middle of the platform, a support rod capable of moving up and down is inserted in the sleeve, a plurality of positioning holes are sequentially provided on the support rod from bottom to top, and a positioning pin capable of being placed in the positioning hole is provided on the sleeve; a blind hole is provided at the upper end of the support rod, a vertical rod capable of moving up and down is inserted in the blind hole, and an electric drill is fixed to the upper end of the vertical rod; a vertical groove communicating with the blind hole is provided on the side wall of the support rod; a lever capable of being placed in the vertical groove is provided at the lower end of the vertical rod; a guide column is provided at the upper end of the support rod, a rope is connected to the lever, and the rope changes direction through the guide column.
