The spring buffer unit is connected to the threaded loading unit. A gear unit for manually or electrically applying a rotation torque is sleeved on the spring buffer unit. The gear unit can be connected to a rotating device or directly manually apply a rotation torque. The threaded loading unit is provided with a thrust unit through the front support. Adopting the technical solution of this patent, it is possible to simulate the different stress states of the test piece moving at different frequencies and amplitudes under a given external load. However, for some aircraft electrical component suppliers, a centrifugal acceleration loading machine is a commonly used device, which is often used to simulate the stress state of electrical components under various simulated operating conditions of aircraft. When the attitude of the aircraft in the air is different, the attitude of the corresponding electrical components is also different. However, the fixtures provided by the prior art often cannot adjust the installation attitude of the electrical components in the centrifugal acceleration loading machine, resulting in the inability of operators to comprehensively master the corresponding test state information.
