O Scope of Claim for Utility Model Registration A guide groove is provided on one end of the underframe that is linearly shaped so as to become lower toward one side, and a swing arm is erected, so that the base of the swing arm is in a j-id position. While it is mounted so that it can move within the groove, a so-called control arm is erected on the other end side of the underframe, and the base of the control arm is pivotally connected to the underframe, and the tip crosses the swing arm. A straight-up type jack, characterized in that the swing arm is pivotally mounted at a position closer to the base side than the center of the length of the swing arm, and an elevating device is mounted on the underframe, and the elevating device is connected to the swing arm.

Claims

[Scope of utility model registration request]

The movable frame includes a fixed frame and a movable frame disposed so as to be movable in a predetermined direction relative to the fixed frame, one end of which is pivotally attached to the frame, and the other end of which is pivoted to the frame. two swing arms extending in the same direction, each pivot point forming a parallelogram link; and a cylinder for raising and lowering the swing arms; Both ends of a control arm arranged to intersect with the swing arm are pivotally connected to the fixed frame and the rotation direction of the control arm and the moving direction of the movable frame relative to the fixed frame. Straight-up jack made to match.
