Control rod guide plate for testing drawing and inserting force of nuclear fuel assembly

The invention discloses a control rod guide plate for testing the drawing and inserting force of a nuclear fuel assembly. The guide plate is characterized in that a main body of the guide plate is matched with an upper tube base of the nuclear fuel assembly; guide holes are formed in the main body; one side, close to the upper surface of the main body, of each guide hole is a horn-mouth-shaped inclined-plane guide surface; one side, close to the lower surface of the main body, of each guide hole is a vertical-plane guide surface; the vertical-plane guide surfaces are matched with guide tubes of the nuclear fuel assembly; the main body is quadrilateral, and four edges of the main body are connected through four arcs; the lower surface of the body is provided with a circular base plane platform used for making contact with the upper tube base of the nuclear fuel assembly; a cylindrical fixing column is arranged at the middle part of the circular base plane platform; and the two sides ofthe cylindrical fixing co
