In order to enable the box pressing strips to uniformly press and hold the packaging boxes arranged in the conveying direction on the conveying assembly, not only do the two box pressing strips need to be located in the same plane, but also the two ends of the box pressing strips need to be kept in the same horizontal plane. However, due to the existence of assembly errors and the relatively long length of the box pressing strips, the two ends of the box pressing strips cannot be kept in the same horizontal plane, so it is necessary to level the box pressing strips when assembling the box pressing strips on the packaging machine. However, the above box pressing mechanism does not have a leveling structure, which causes inconvenience in leveling the box pressing strips. Practical new type
