Description

technical field

[0001] The present invention relates to a clamp. Background technique

[0002] Among the existing material compression fixtures, most of the fixtures are for block specimens. Few fixtures are used for sheet-like specimens, and most of the sheet-like specimen fixtures are disassembled and disassembled. In the middle, there is a square slot and is coupled with four wedge blocks (positive and negative combined into a square). When carrying out the compression test, the sheet-like specimen is clamped on the surface side of the two wedge-shaped blocks with the diamond-shaped mouth, and then placed on the platen of the universal testing machine to apply a load for the compression test of the specimen. There are the following shortcomings and deficiencies in the process of loading and unloading the test piece: 1. It is difficult to install the test piece in the center and apply the preload force: during the installation process of the test piece, the preload force...
