The invention discloses a novel box wrench. The novel box wrench comprises a wrench body and boxes. Driving of the wrench body is performed through a universal shaft, the wrench body is in a crossed shape, and the boxes are arranged on four portions correspondingly. The novel box wrench provided by the invention has the beneficial effects that nut ends or bolt ends can be completely lower than connected surfaces, and the diameters of concave holes can not be used for an open end wrench or a monkey wrench and a double offset ring spanner; after driving is performed through the universal shaft,the novel box wrench is applicable to multiple directions, different working angles and working environments of different specifications and different conditions; and a moment arm of the longer portion of the wrench body can be increased, and thus, the torque is larger when the same force is applied.
