Hydraulic cable bending device

The invention discloses a hydraulic cable bending device, which relates to a tool for cable construction, and is characterized in that the hydraulic cable bending device comprises a support, a bracket, a limiting device and a manual hydraulic pump, one end of the manual hydraulic pump is connected with a handle, the other end of the manual hydraulic pump is connected with the bracket, and the manual hydraulic pump pushes the bracket to move so as to extrude a cable to be bent to an expected angle; the manual hydraulic pump is installed on the support, a limiting device is arranged on the support and comprises a first rolling guide wheel, a second rolling guide wheel and a limiting plate, one end of the limiting plate is connected with the first rolling guide wheel, and the other end of the limiting plate is connected with the second rolling guide wheel and used for limiting the bending track of a cable. And the situation that the bending angle does not reach an expected value due to the fact that the cable is
