Description

[0002] During installation engineering construction, workers often have to use handheld machines such as electric drills to perform top drilling operations, and auxiliary objects such as scaffolding will be used for construction. However, due to the complex actual construction environment on site and the large number of cross-operations, there is often not enough space for scaffolding construction, and frequent movement of scaffolding will also reduce construction efficiency.

[0003] In order to solve the above technical problems, a Chinese patent (patent announcement number: CN211362960U) discloses a mobile top drilling auxiliary bracket, which uses a set of mutually linked parallel four-linkages to replace the scaffolding.
