The invention relates to a tool which is used for dismounting a plum blossom contact for switching in a
high voltage electrical product, comprising a retaining base, top plates and an adjusting rod; the retaining base is provided with a centre hole, the adjusting rod penetrates through the centre hole and is extended out of the retaining base and is movably arranged with the retaining base, a plurality of the top plates are circumferentially and movably arranged on the end surface of the retaining base by taking the adjusting rod as the axle to form a top plate group, an elastic reset device is circumferentially arranged on the top plate group, an inclined surface is arranged at one side of top plate, which is toward to the axle, the inclined surfaces on a plurality of top plates which form the top plate group circumferentially form a cone-shaped adjusting cavity, the end part of the adjusting rod is arranged in the cone-shaped adjusting cavity, and the
diameter of the end part of the adjusting rod is more than the
diameter of the top part of the cone-shaped adjusting cavity. The tool has the advantages that: the plum blossom contact is dismounted conveniently and quickly, the plum blossom contact can be effectively protected from not being damaged, the passing percent of the product is increased, the
manufacturing efficiency is increased and the potential safety
hazard is eliminated.
