[0002] Stainless steel pipe is a hollow, long, round steel bar widely used in industrial pipelines and mechanical components in the petroleum, chemical, medical, food, light industry, and instrumentation industries. Furthermore, its light weight, while maintaining the same bending and torsional strength, makes it widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used in furniture and kitchenware.

[0003] When installing and assembling stainless steel pipes, in order to facilitate installation and improve stability, it is necessary to drill holes on their surfaces for assembly. Under fixed size conditions, they can be directly formed during production and processing, but they still need to be adjusted according to the size and adaptable shape of the actual installation location. At this time, a portable drilling machine is generally used to drill holes. Since the pipe is cylindrical, holes drilled on the curved surface will deviate even if there are marks, and the verticality of the hole cannot be guaranteed. Slippage causes the drill bit to slide on the stainless steel surface, affecting the appearance and reducing durability. Non-vertical holes affect the installation accuracy and are prone to irreversible deviations. In this regard, a portable stainless steel pipe hole drilling and positioning device is proposed to solve the above problems. Utility Model
