Carton compressive strength test device with side supports

The invention relates to the technical field of compressive strength testing devices, in particular to a carton compressive strength testing device with side supports. The carton compressive strength testing device comprises a machine body and a supporting mechanism; the supporting mechanism can support the periphery of the carton under the action of friction force when the compressive strength of the carton is detected, so that the state that the periphery of the carton is supported by other cartons when the carton is stacked is simulated; when a compressive strength test is carried out on the carton, the mounting blocks drive the supporting plates to support the periphery of the carton, so that the state that the periphery of the carton is supported by other cartons after the carton is stacked together in actual use is simulated, and the state of the carton in the test is more fit with the actual state; meanwhile, the periphery of the carton is supported through friction force between a friction block and t
