Circuit board lifting frame

The utility model relates to the technical field of circuit board processing, and discloses a circuit board lifting frame which comprises a bottom plate, brake wheels are fixedly connected to the bottom of the bottom plate, a functional mechanism is arranged on the top of the bottom plate, a side plate is fixedly connected to the top of the bottom plate, and a limiting assembly is fixedly connected to the front side of the side plate. The sides, away from each other, of the two side plates are fixedly connected with handles. According to the circuit board lifting and conveying frame, a functional mechanism is arranged, a second threaded rod is rotated, a top plate can be driven to move downwards, accordingly, rectangular rubber pipes below the top plate and a movable plate move downwards, circuit boards of different models can be lifted and conveyed, and when the circuit boards of different models need to be carried at the same time, a first threaded rod can be rotated; the movable plate is driven to move dow
