Claims

[Scope of Claim for Utility Model Registration] 1. Assemble four links in a rhombus shape through mounting pins, and insert a threaded rod into the two pins that overlap and connect the upper and lower links so as to be rotatable, and screw the screws by an electric motor. It is a pantograph type power jack that raises and lowers a receiving plate using a base as a fulcrum by rotation of a rod, and a small diameter part is provided at the rear part of the threaded rod with a length that allows the female threaded hole of the front connecting pin to fit into it. The diameter of the part is smaller than the inner diameter of the female threaded hole, and an elastic member is installed close to this small diameter part, so that when the female threaded hole of the front connecting pin fits into the small diameter part of the threaded rod, this A power jack that urges the connecting pin outward. 2. The power jack according to claim 1, wherein the tip of the threaded rod is also provided with a small diameter part long enough to fit into the female threaded hole of the front connecting pin, and the diameter of the small diameter part is smaller than the inner diameter of the female threaded hole. . 3 Assemble the four links in a diamond shape through the mounting pins, and insert the threaded rod into the two pins that connect the upper and lower links so that they can rotate freely, and use the base as a fulcrum by rotating the threaded rod with an electric motor. It is a pantograph-type power jack that raises and lowers a receiving plate, and the plug for the electric motor is connected to the cigarette lighter socket of a car when in use, and the receiving plate installed on the connecting pin at the rear holds the electric motor and gearbox. If the rotating shaft of this gearbox is inserted into the square hole on the rear end of the threaded rod and the removable electric motor and gearbox are removed, a manual handle will be inserted into the square hole on the rear end of the threaded rod, either directly or through a bracket. Power jack that can be installed.
