Fixed ammeter hook

The utility model relates to a fixed ammeter hook, being characterized in that the fixed ammeter hook is formed by a hook head, a hang arm, a stop hook and a spanner integratedly; the action force of the hook head is opposite to the action force of the stop hook; when the fixed ammeter hook is used,...

description The utility model relates to a fixed ammeter hook, being characterized in that the fixed ammeter hook is formed by a hook head, a hang arm, a stop hook and a spanner integratedly; the action force of the hook head is opposite to the action force of the stop hook; when the fixed ammeter hook is used, firstly an ammeter fixed lug through hole and an ammeter box fixed through hole are aligned; the hook head penetrates adown through the ammeter fixed lug through hole and the ammeter box fixed through hole by means of handing the hand-held spanner so as to make the hook head hook an ammeter box fixed point so that the ammeter is hitched on the hang arm and the stop hook contacts the fixed lug of the ammeter; and although the ammeter suffers the action of gravity, action force of the hook head is opposite to the action force of the stop hook, and the magnitude of the forces are equal, thus fixedly hitching the ammeter on the hang arm. The fixed ammeter hook has the advantages of being simple in structure, being con
