Technical Field

[0001] The utility model belongs to the technical field of scaffolding, in particular to a high-precision drilling device for connecting pieces in a scaffolding. Background Art

[0002] Scaffolding is a working platform set up to ensure the smooth progress of each construction process. It can be divided into external scaffolding and internal scaffolding according to the location of the scaffolding; it can be divided into wooden scaffolding, bamboo scaffolding, and steel pipe scaffolding according to the different materials; it can be divided into vertical pole scaffolding, bridge scaffolding, portal scaffolding, suspended scaffolding, hanging scaffolding, cantilever scaffolding, and climbing scaffolding according to the structural form.

[0003] At present, the connectors in the scaffolding on the market need to be drilled according to specifications after the rolling process so that the steel pipes can be connected and fixed to form the scaffolding. Since the connectors in the scaffolding are irregular in shape and their side walls are mostly curved, it is difficult for the existing drilling device to clamp and fix them well, which can easily cause the connector to vibrate under the force of the drill bit, causing the position of the processing hole of the connector to shift, thereby reducing the accuracy of the drilling device.
