The invention relates to a protective clamp for an LED chip circuit board. The protective clamp comprises a foldable cuboid-shaped box body, wherein the box body comprises an accommodating box and a turning cover which is connected with the right side of the accommodating box through a hinge; the accommodating box comprises an accommodating cavity and an air-supplying cavity; a left bracket and a right bracket are arranged in the accommodating cavity in parallel; the left bracket is hinged with the protective clamp, and an annular groove which can be matched with the right bracket is formed in the bottom of the right end of the protective clamp; the protective clamp is provided with multiple siding rails which are formed in parallel, and the sliding rails are both matched with multiple chip protective boards; a pair of clamping tracks which can be clamped with the circuit board are arranged on the lower end plane of the protective clamp; the air-supplying cavity and the sliding rails are arranged in parallel, and exhaust fans are arranged in the air-supplying cavity; and the accommodating cavity is formed in the turning cover corresponding to the air-supplying cavity. Therefore, the protective clamp for the LED chip circuit board is simple and creative in structure; the air-outlet direction is reasonably set; and in addition, the protective clamp is quite convenient to move by an operator.
