The invention discloses a forcible entry tool for a broken connector. The forcible entry tool for the broken connector comprises a sleeve, wherein a saw frame is arranged in the sleeve, the position of the saw frame can be adjusted in the radial direction of the sleeve and in the axial direction of the sleeve, a saw frame positioning mechanism is arranged between the saw frame and the sleeve, and a sectioning saw is arranged on the saw frame in the mode that the sectioning saw can slide in the axial direction. When the forcible entry tool is used for dismantling the broken connector forcibly, after the sleeve is made to be in butt joint with a pipe and the cutting depth is set, a user just needs to push and pull the sectioning saw and does not need to control the force exerting degree when the broken connector is to be sawn off, as a result, labor intensity is relieved, and working efficiency is improved; due to the fact that the cutting depth can be set and adjusted instead of being controlled according to hand feeling, the broken connector can be sectioned accurately, and the risk that the threads of the pipe are damaged is reduced.
