The invention discloses a convenient lifting machine with wide-angle supporting arms. The lifting machine comprises an upright column, an ascending and descending rack and supporting arms. The lifter is characterized by also comprising connecting devices, wherein each supporting arm and the ascending and descending rack can make rotating cooperation through the corresponding connecting device; each connecting device comprises a fixed gear, a sliding gear, a limit sleeve, a pull rod and a spring; each fixed gear is an external bevel gear; each sliding gear is an internal bevel gear; each limit sleeve is fixed on the corresponding supporting arm; an elongated slot is formed in each limit sleeve; through holes are respectively formed in the sliding gears and the pull rods; through the through holes, each sliding gear and the corresponding pull rod are fixedly connected by a screw; the head of each screw is placed in the corresponding elongated slot and makes sliding cooperation with the elongated slot; the fixed gears are mounted on the ascending and descending rack; each fixed gear is meshed with the corresponding sliding gear. According to the convenient lifting machine disclosed by the invention, the supporting arms can rotate by 180 degrees; because the rotating angle of the supporting arms is increased, when an automobile is maintained, the lifting machine can be applicable to various working situations, so that the maintenance efficiency of maintenance staff is improved, and convenience is brought to the maintenance staff.
