Description

Convenient stretching length's of observing core jack Technical Field The utility model relates to the technical field of jacks, in particular to a through jack convenient for observing stretching length. Background The penetrating jack is mainly used for overall tensioning of group anchors, and plays an important role in prestress construction of bridges, buildings and the like by virtue of the characteristics of simplicity in operation and reliable performance of the penetrating jack and cooperation of products such as prestress anchors, tensioning equipment and the like. When the head end and the tail end of the existing through jack extend outwards, workers cannot judge the extending distance of the existing through jack, so that most of workers manually measure the existing through jack during measurement, and accurate numerical values cannot be obtained to meet calculation requirements. For this purpose, a solution needs to be given. Disclosure of utility model (One) solving the technical problems Aiming at the defects of the prior art, the utility model provides a penetrating jack which is convenient for observing the stretching length so as to solve the problems in the prior art.
