Hanging hook enabling replacement of single straight line insulator

The invention provides a hanging hook enabling the replacement of a single straight line insulator. The hanging hook comprises a hook body; a plurality of fixing holes are formed at the tail part of the hook body from top to bottom; a fixing ring is movably connected in the fixing holes; the fixing ring is connected with a hanging hook; the bent portion of the middle of the hook body of the hanging hook is semicircular; and the tip end of the front part of the hook body extends outwards and obliquely so as to form a flange. According to the hanging hook enabling the replacement of the single straight line insulator of the invention, the insulator can be locked onto a wire through the hanging hook during construction operation; the bent portion of the middle of the hook body is semicircularso as to match the diameter of the wire, so that stability can be high; and the tip end of the front part of the hook body extends outwards and obliquely so as to form the flange, so that the wire can be hooked conveniently,
