The invention discloses a solder sucker for an electronic element. Pins are fixedly connected to the lower end surface of the electronic element, a circuit board movably sleeves the pins, the pins andthe circuit board are fixedly connected by virtue of tin soldering blocks which are movably inserted into a tin sucking barrel, a heat insulation sleeve is fixedly connected to the lower end of the tin sucking barrel, a limiting plate is fixedly connected to the inner wall of the heat insulation sleeve, a tin storage sleeve is fixedly connected to the lower end surface of the heat insulation sleeve, a discharge pipe is fixedly connected to the lower end of the tin storage sleeve, a switch is fixedly connected to the outer side wall of the discharge pipe, and a one-way sleeve is fixedly inserted into the discharge pipe. The structure of the solder sucker is simple, the pins and the tin soldering blocks are inserted into a first annular electric soldering iron and are abutted with each other, the tin soldering blocks are heated and molten, molten tin is sucked into the tin storage sleeve, and an ejector pin is pushed, so that the molten tin is extruded from the one-way sleeve. The solder sucker has the advantages of convenience in use and simplicity in operation, and the working efficiency is improved.
