Abstract

The invention relates to the technical field of mechanical parts, in particular to a portable lamp mounting screw. The portable luminaire mounting screw comprises an outer screw body and an inner screw body. The outer screw body comprises an outer screw rod. An outer screw head is arranged at one end of the outer screw rod. A self-tapping thread is arranged on the outer screw rod. A hollow cavityis formed in the outer screw head and the outer screw rod. The inner screw body comprises an inner screw rod with an outer thread. An inner screw head is arranged at one end of the inner screw rod. The inner screw rod is matched with the hollow cavity. By the adoption of the portable lamp mounting screw, the time and labor can be saved when a lamp is mounted on a material such as a wood board or agypsum board, and disassembly is convenient.

Description

technical field [0001] The invention relates to the technical field of mechanical parts, in particular to a portable lamp mounting screw. Background technique [0002] At present, when fixtures are installed on wooden boards or plasterboards and other materials in the market, percussion drills must be used to drill holes and expansion tubes need to be filled in the holes. This installation operation is not only time-consuming and laborious, but also inconvenient to disassemble. [0003] Such as Figure 8 Shown is a schematic diagram of a traditional lamp installation method. When installing the lamp mounting bracket 18 on a wooden board, not only does it need to use a percussion drill to punch holes in the wooden board in advance, but also needs to fill the hole with an expansion tube 19, resulting in not only Time-consuming and labor-intensive, and inconvenient to disassemble. Contents of the invention [0004] The present invention mainly aims at the time-consuming and ...
