| description | The utility model relates to the technical field of constructional engineering detection and identification, in particular to a portable corer for concrete core drilling. Comprising a first control rod, a second control rod, a first sandwich rod and a second sandwich rod, and the first control rod and the second control rod are connected through a first steel wire shaft; the first sandwich rod is connected with the second sandwich rod through a second steel wire shaft, the lower end of the first control rod is connected with the upper end of the second sandwich rod through a third steel wire shaft, and the lower end of the second control rod is connected with the upper end of the first sandwich rod through a fourth steel wire shaft. The portable corer for concrete core drilling provided by the utility model is simple in structure and practical, can effectively solve the problem that a to-be-taken core sample cannot be completely and smoothly taken out after concrete core drilling, ensures that the to-be-taken |
