The invention discloses a portable new energy automobile jack. The portable new energy automobile jack comprises a double-head lead screw, wherein a force application head is arranged at the right endof the outer wall of the double-head lead screw, the left side and the right side of the outer wall of the double-head lead screw are sleeved with short barrels, the inner walls of the short barrelsare in threaded connection with the inner wall of the double-head lead screw, and inclined rods are rotationally connected to the upper ends and the lower ends of the outer walls of the short barrels.According to the portable new energy automobile jack, through cooperation among the double-head lead screw, the force application head, the short barrels, the inclined rods, supporting blocks, hingepins and an anti-skid pad, the inner wall of a sleeve is in engaged connection with a spline on the outer wall of a circular ring on the right side, then force is applied to the sleeve for clockwise rotation, so that pawls lose transmission to ratchet wheels, then the double-head lead screw cannot be stressed to rotate, and therefore, an external wrench does not need to be rotated for multiple circles; and the wrench cannot be repeatedly mounted and dismounted for multiple times due to a narrow internal space under the bottom of an automobile so that the double-end screw rod can be conveniently rotated by applying force.

    本发明公开了一种便捷式新能源汽车千斤顶,包括双头丝杆,所述双头丝杆的外壁右端设有施力头,所述双头丝杆的外壁左右两侧均套接有短筒,所述短筒的内壁与双头丝杆的内壁螺纹相连,所述短筒的外壁上下两端均转动连接有斜杆。该便捷式新能源汽车千斤顶,通过双头丝杆、施力头、短筒、斜杆、托块、销轴和防滑垫之间的配合,将套筒的内壁与右侧圆环外壁的花键啮合相连,然后对套筒进行施力进行顺时针转动,使棘爪失去对棘轮的传动,继而双头丝杆不会进行受力转动,因此可以实现无需对外界扳手进行多圈转动,不会因车底内部空间的狭小对扳手进行多次反复的安装拆卸,因此能够较为便捷的对双头丝杆进行施力转动。
