The invention discloses a portable crowbar device. The portable crowbar device comprises a first support cross beam and a second support cross beam, wherein the first support cross beam is rotationally connected with the second support cross beam through a pin; a first connecting through hole is formed in the top of the first support cross beam; a second connecting through hole is formed in the top of the second support cross beam; an adjusting cross bar is detachably arranged between the first connecting through hole and the second connecting through hole; and an adjusting handle capable of rotating is arranged at the tail end of the adjusting cross bar. The portable crowbar device uses the first support cross beam and the second support cross beam which are connected in a Y form, so that users can easily adjust an opening angle of the two support cross beams to change the height of a whole crowbar; the structure is simple and compact; and the use is convenient. In addition, as a limiting bearing, a limiting stop piece and a C-shaped limiting clamping ring are arranged at the head part of the adjusting cross bar to prevent the sliding of a bearing part, the safety of the whole crowbar is improved.
