The invention discloses a leakage protector capable of adjusting the fixture range. The leakage protector comprises a supporting base and a support, the support is located at one side of the supporting base, a first electric telescopic rod is arranged on the upper surface of the supporting base, a thread cap is fixedly connected to the top end of the first electric telescopic rod, a threaded column is in thread connection with the interior of the thread cap, and one end of the threaded column is fixedly connected with a handle arranged at one side of the first electric telescopic rod. By arranging the first electric telescopic rod, the leakage protector achieves the fixture height adjusting effect; by arranging the handle, the threaded column, the thread cap, a bearing, a first connecting block, a hinge pin, a connecting plate, a sliding rod, a strip-shaped sliding groove, first sliding grooves, a first sliding block, a second sliding block and a clamping block, the effect of slightly adjusting the fixture height is achieved, and therefore a fixture can clamp the leakage protector more accurately, the condition that the leakage protector inclines or shakes in use can be better avoided, and the safety of the leakage protector is enhanced.
