Concrete cube test piece compressive strength test limiting device

The utility model discloses a concrete cube test piece compressive strength test limiting device which comprises a controller, sliding parts, telescopic parts and size limiting parts, the sliding parts are assembled and connected to the end faces of the two sides of a lower bearing plate of a testing machine, the telescopic parts are arranged on sliding parts of the sliding parts, and the size limiting parts are arranged on the telescopic parts. The size limiting part is assembled and connected with one end of the telescopic part, and the sliding part and the telescopic part are electrically connected with the controller. Related data (the side length of the cubic test block, the front length of the lower pressure-bearing surface of the testing machine and the side length of the lower pressure-bearing surface of the testing machine) are set through the controller, so that the positions of the sliding component and the telescopic component can be adjusted, the placement position of the cubic test block is cont
