Claims

[Scope of utility model registration request]

A threaded rod 3 is located between the lower frame 1 and the upper frame 2, with the front and rear parts having opposite screw directions.
is provided horizontally, and a pair of bending arms 4a and 4b
The lower ends of the bending arms 4a and 4 are connected to the lower frame 1 so as to be rotatable in a vertical plane.
The upper end of b is connected to the upper frame 2 so as to be rotatable in a vertical plane, nuts are connected to the bent parts of bending arms 4a and 4b, and the nut connected to 4a is connected to the front half of the threaded rod 3. The nut connected to 4b is engaged with the rear half of the threaded rod 3, and the lower ends of the pair of cross arms 5 are connected to the lower frame 1.
The upper ends of the pair of cross arms 5 are connected to the upper frame 2 so that they can freely reciprocate in the front and rear directions, and the operating handle 6 is provided at the rear end of the threaded rod 3. Features a liftable cart with a loading platform.
