The invention discloses a mechanical arm of a hot-line work robot, and relates to the field of robots, the mechanical arm comprises a climbing mechanism and a manipulator, the manipulator is located above the climbing mechanism, a tightening assembly is arranged on the manipulator, the tightening assembly comprises an electromagnet, a sleeve is arranged in the manipulator, and a limiting guide groove is formed in the sleeve. Through the electromagnet, the sleeve, the extension rod, the spring, the limiting guide block and the limiting guide groove, the connector is attracted through the electromagnet, the structure is simple, the fixing speed is high, meanwhile, the extension rod retracts into the sleeve to compress the spring due to the fact that the socket spanner is pressed, and the output end drives the sleeve to rotate after the motor is started; torque is transmitted through the limiting guide block and the limiting guide groove so that the extension rod and the socket spanner can rotate to tighten the
