The application of the portable new energy automobile jack according to claim 1, is characterized in that: when the portable new energy automobile jack is used, firstly, an upper support block (6) and a lower support block (6) are placed between the ground and a bulge near an automobile chassis wheel, force can be applied to the support block (6) at the bottom end in the fine adjustment process of aligning the support block (6) at the top end with the automobile chassis, the universal wheel (704) can roll, then the position of the support block (6) can be adjusted in a labor-saving manner, after the position adjustment is completed, the knob (707) is rotated anticlockwise, the universal wheel (704) is accommodated in the groove (702), the lower surface of the bottom plate (701) can be abutted against the ground, then, the inner wall of the sleeve (209) is meshed and connected with the spline (208) on the outer wall of the right circular ring (201), then, the sleeve (209) is rotated clockwise, in the force application process of the sleeve (209), firstly, the hand (801) and the lug (802) can be connected with the sleeve (209) in a threaded manner, at the moment, the handle (801) is held to facilitate the force application rotation of the sleeve (209), and meanwhile, when the handle (801) is not convenient to hold, an operator can pull the cross rod (804) outwards, and rotate the bolt (805) clockwise to position the cross rod (804), at the moment, the operator can hold the cross rod (804) to shake to rotate the sleeve (209), so that the operator can apply force to the sleeve (209), namely, the double-end screw rod (1) can rotate clockwise, the two ends of the inclined rods can rotate relative to the pin shaft (5) along with the clockwise rotation of the double-end screw rod (1), the top end support block (6) can move upwards to jack up the chassis of the automobile, and the pawl (205) can be separated from the inner part of the ratchet (202) during the anticlockwise rotation of the sleeve (209), so that the pawl (205) loses the transmission of the ratchet (202), then double-end lead screw (1) can not carry out the atress and rotate, consequently can realize need not to carry out many circles to external spanner and rotate, consequently can be comparatively convenient carry out the application of force to double-end lead screw (1) and rotate, and need descend operation messenger with top tray (6), link to each other the inner wall of sleeve (209) and ring (201) outside spline (208) meshing of opposite side, it can to the application of force rotation of sleeve (209) repeatedly.
