The invention discloses a clamping part capable of conveniently extracting objects from a storehouse frame one by one. The clamping part comprises a rack extending downwards and a seat body used for installing the rack. The rack is provided with a containing part contained in the seat body. A clearance capable of containing the rack so as to swing perpendicular to a rack face is arranged between the rack and the seat body. The seat body is provided with a limiting part abutting against the end portion of the containing part of the rack. A spring for maintaining the lower end of the rack tend to swing back to the rack face is installed between the containing part and the seat body. The force for clamping the objects can be adjusted only by adjusting the installation positions of clamping parts on the two sides according to the size specification of the objects on the warehouse frame. Due to the spring installed between the containing part and the seat body to maintain the lower end of the rack tend to swing back to the rack face, the clamping force of the objects at the lower end of the rack can be reduced, the clamping force of the objects at the lower ends becomes smaller from top to bottom, the force generated when the objects are extracted is reduced, and the reliability for extracting the objects from the warehouse frame one by one is ensured.
