[0002]

[Prior art]

 A clamp device that relatively moves a pair of holding plates by rotation of a screw rod and holds a load from both sides with the pair of holding plates is widely used for transporting and changing the direction of the load.

[0003]

[Problems to be solved by the device]

 By the way, in the conventional clamp device, a non-slip plate is attached to the inner surface of the holding plate to increase the engagement force with respect to luggage, but the box for storing the product does not have the friction like a corrugated ball box. If the material is made of a material with a relatively small coefficient, there is a risk that the package will fall during transportation.

In addition, when the luggage is stacked on the pallet, the luggage is conveyed on the pallet to drop the luggage by opening the pair of holding plates. There is a problem that the luggage cannot be stacked in an aligned state because the luggage may be engaged with one of the holding plates and fall in an inclined state due to a leaning or the like.

An object of the present invention is to solve the above-mentioned conventional problems, and to provide a clamp device capable of safely transporting loads without dropping them and stacking them in an aligned manner.
