Claims

[Claims for Utility Model Registration] An operating shaft is incorporated into a mechanism in which links are connected by node members, and a U-shaped joint is provided at the end of this operating shaft with the open end facing outward on the operating axis. The target of the drive is a jack in which a node member located near this U-shaped joint protrudes outward from the side surface of the jack, and the lifting platform is raised and lowered by rotating the U-shaped joint. , a rotary drive motor having an output shaft connected to the U-shaped joint;
This is a removable drive device for a jack, which is equipped with an arm for fixing the main body of the rotary drive motor to the jack to prevent it from rotating, and the output shaft of the rotary drive motor is connected from the open end of the U-shaped joint to the same end. a central engaging piece that can be inserted into the recess of the joint; and a pair of central engaging pieces that are formed at both ends of the central engaging piece and are located on both sides of the U-shaped joint when the central engaging piece is inserted into the recess. The arm is provided with a connecting portion basically having an H-shaped cross-section and an outer engaging piece, and the arm has a proximal end attached to the main body of the rotary drive motor, and a distal end attached to the U-shaped portion of the jack. A removable drive device for a jack, characterized in that it is configured to be able to engage with an outwardly protruding portion of a node member located near a joint.
