This utility model relates to the field of durability testing technology, specifically a solid-state drive (SSD) insertion / removal durability testing fixture. It includes a test base, a feeding mechanism, a gripping mechanism, and an insertion / removal mechanism. The feeding mechanism is mounted on the surface of the test base and includes a conveyor frame, a conveyor belt, and a conveyor motor. It can quickly and accurately align the gripping claw with the SSD under test, and the gripping force can be naturally adjusted according to the spring compression. This avoids damage to the SSD casing caused by rigid gripping while ensuring effective clamping of the SSD. The pawl, under the elastic force of the second spring, continuously engages with the ratchet tooth groove, forming a one-way locking structure. This completely restricts gear reversal, thereby locking the position of the pressure plate and ensuring that the gripping claw maintains a stable clamping force. Even if the electric telescopic rod experiences slight extension or contraction, or if the equipment vibrates during operation, it will not loosen, providing absolutely stable gripping assurance for subsequent lifting, conveying, and other processes.
