Novel cohesiveness testing device

The utility model relates to the technical field of testing devices, in particular to a novel cohesiveness testing device, which can reduce the error of a measurement result and improve the measurement precision by slowly applying thrust without a pressure sensor with high sensitivity. Comprising a flat plate, a pressing assembly, a sliding block, a thrust sensor and a push plate, the pressing assembly is installed at one end of the flat plate and used for installing a sample test piece, the sliding block is installed at the other end of the flat plate in a sliding mode and slides towards the pressing assembly, the thrust sensor is installed on the sliding block, and the push plate is installed at the measuring end of the thrust sensor; the motor is mounted on the flat plate, an output shaft of the motor is in transmission connection with the screw, the screw is concentrically and rotatably screwed in the threaded sleeve, the threaded sleeve is connected with the sliding block, and the screw and the threaded
