[0002] Wooden pallets are made of logs, which are dried and shaped to reduce moisture and eliminate internal stress. Then, they are cut, planed, cut off, edged, sanded and other finishing processes are performed to form profile plates. The profile plates are bound into semi-finished pallets using nails with anti-slip function (nut structure is used in some cases), and finally they are finished, anti-slip and waxed. Wooden pallets are the most widely used pallets. When wooden pallets are prepared, their longitudinal beams have a large span. After long-term storage, they will bend and deform due to water loss, which will affect the subsequent installation of the pallet. Therefore, when preparing the longitudinal beams of the pallets, corresponding straightening structures are needed to straighten them. However, when the existing pallet longitudinal beam straightening structures are used, they can only straighten a single longitudinal beam at a time, and cannot perform effective lifting operations, which makes it easy for the wooden board to fall during straightening, which has limitations.

[0003] Therefore, in view of the shortcomings of the above-mentioned scheme in actual production and implementation, it has been revised and improved. At the same time, in the spirit and concept of seeking excellence, with the assistance of professional knowledge and experience, and after many ingenuity and experiments, the present utility model was created.
