The invention discloses a disassembling tool for a bird repellent apparatus. The disassembling tool comprises a telescopic pipe assembly, a control cover, a first inner corner sleeve head, a second inner corner sleeve head, and a protection plate, wherein the telescopic pipe assembly comprises an outer pipe and an inner pipe; the control cover is fixed outside the upper part of the outer pipe; a U-shaped groove which is used for accommodating a U-shaped base of the bird repellent apparatus is formed in the control cover; the first inner corner sleeve head is coaxially arranged above the inner pipe and can rotate along with the inner pipe; the second inner corner sleeve head is arranged outside the middle part of the outer pipe and can move vertically along with the inner pipe; the second inner corner sleeve head is opposite to a set screw which is connected at the lower part of the U-shaped base; and the protection plate is arranged at the upper end of the control cover for surrounding the periphery of a main shaft, which extends out of the control shaft, of the bird repellent apparatus. According to the disassembling tool, the bird repellent apparatus can be mounted on or disassembled from a linear carrying plate through the control cover; and in addition, the U-shaped base is tightly fastened by the first inner corner sleeve head, thereby finishing the disassembling of the bird repellent apparatus.
