The invention relates to the field of electric element welding auxiliary equipment, in particular to an electric soldering iron with a conveying mechanism. The electric soldering iron comprises an electric soldering iron body, wherein the electric soldering iron body consists of a handle, an electric heating wire pipe and a soldering iron rod, a spring switch is arranged on the handle, a ratchet conveyer is arranged at the joint of the handle and the soldering iron rod, the ratchet conveyer comprises a conveying pipe, a conveying ratchet and a casing, the conveying ratchet arranged in the casing is an internal engagement ratchet comprising a ratchet pawl and an outer ring, the rotating center of the ratchet pawl is connected to the handle through a coiled spring, conveying teeth inclining towards one end of the soldering iron rod are arranged on the edge of the outer ring, an arc-shaped half-pipe is arranged on the upper surface of the casing, a tin wire threading channel is formed between the outer ring and the arc-shaped half-pipe, the conveying pipe is concentric with the arc-shaped half-pipe and extends to the end part of the soldering iron rod, and the spring switch is connected with the ratchet pawl through a pull rod. The electric soldering iron has the benefits that the conveying purpose can be achieved as long as the spring switch is pushed, and tin can be replenished only through right-hand operation.
