The invention discloses a portable low-voltage electromagnetism riveter applied to the electromagnetism riveting technology, which mainly provides an electromagnetism riveting method for the work condition with poor openness of a riveting and operation environment of a medium-small rivet and high requirement on the flexibility of riveting process, and changes the current situation of large volume, heavy mass and inflexible operation of the existing electromagnetism riveter. The technical structure of the invention is composed of a front cover, a shell, a rear cover, a spring slideway, a rear cover flange, a coil, an amplifier, a punch, a rubber shock absorber, a damping spring and other components; under the low pressure condition of 300-1000V, the riveter can be used for carrying out the riveting of a high-strength aluminum alloy riveter with the diameter of 5mm or the riveting of the riveter with medium-small diameter made of other metal materials. The total mass of the riveter is as light as 3.0-4.5kg, is convenient to handheld operation, has remarkable damping effect, low recoil and high operation flexibility and reduces the labor intensity.
