The invention discloses a sewer dredge, and belongs to the field of cleaning tools to achieve the aim of being convenient for use. The technical scheme is as follows: the sewer dredge is mainly composed of a handle, a crankshaft and a connecting set, and further comprises a mechanism composed of a connecting hole, a metal claw and a control needle and matched with the connecting set, and a mechanism composed of the connecting hole, a flexible shaft and a flexible claw and matched with the connecting set, wherein the control needle is made of metal and installed in the middle part of the metal claw; the connecting set is connected with the connecting hole, the metal claw automatically inwardly shrinks while encountering blockage in the down-pass process, and the whole needle entirely inserted in the blockage is pulled out, the metal claw automatically slides out like a condition that a folded umbrella is unfolded, so that the blockage is pulled out; when the dredger is used for dredging bent pipeline, the flexible shaft and the flexible claw are inserted into the blockage after stretching into the bent pipeline, the handle is tightly held by a hand and continuously shaken; when the flexible claw firmly grasps the blockage, the dredge can be pulled out. The design structure is reasonable, the use is convenient, and the dredge is easy to popularize.
