A portable spiral claw type jack belongs to the technical field of jacks and comprises an outer shell, a central control pile is arranged in the outer shell, a chassis is in threaded connection with the lower portion of the interior of the outer shell, a long column is rotationally connected to the upper end of the chassis, a threaded groove is formed in the upper portion of the exterior of the long column, and a positioning ring is connected to the exterior of the long column in a sleeving mode. The operation rotating handle rotates to drive the middle shaft and enable the circular teeth to synchronously rotate along with the middle shaft, the middle shaft drives the small bevel gear and enables the large bevel gear to synchronously rotate, and the large bevel gear rotates to drive the long column and enable the threaded groove to rotate in the sleeve at the same time. The sleeve is spirally driven to ascend in the outer shell and drive the top plate to synchronously ascend to extrude and push an object, meanwhile, the rotating handle is arranged outside the outer shell and connected with the middle shaft into a whole, the portability of the device is effectively improved, and by arranging the lifting plate, the problem that the bottom of the lifted object is limited in operation space is solved.
