[0002] The universal material testing machine uses a microcomputer to control a fully digital broadband electro-hydraulic servo valve to drive a precision hydraulic cylinder. The microcomputer control system automatically controls the test force, displacement, and deformation in multiple modes to complete the tensile, compression, and bending tests of the specimen.

[0003] After extensive searching, the reference patent number is CN214538971U, a universal material testing machine with automatic return function. The equipment can prevent the debris from splashing and injuring the operator after the workpiece collapses, thereby improving the safety of the device, facilitating the collection of the workpiece and improving the convenience of the device.
