Gate-type mechanical test mechanism and gate-type mechanical test machine

The invention discloses a gate-type mechanical test mechanism which comprises a workbench, a tested sample mechanism, a driving guide mechanism and a cross beam mechanism, the driving guide mechanismcomprise two groups of driving mechanisms symmetrically arranged on the two sides of the workbench and four groups of guide mechanisms arranged at four corners of the workbench; the gate-type mechanical test mechanism further comprises a displacement sensor and a force sensor. The displacement sensor comprises a main body part and a detection part which moves relative to the main body part to convert mechanical displacement into resistance or voltage outputted in a linear or arbitrary function relationship with the main body part. The main body part and the detection part are separately and independently arranged on the static test mechanism part and the end side of the force sensor of the tested sample mechanism; the force sensor is arranged between the tested sample mechanism and the middle cross beam and is str
