The invention provides an integrated wrench with an anti-dropping part. The integrated wrench comprises a wrench body, the anti-dropping part and a pushing device, wherein a mounting slot is formed in the upper end surface of the wrench body; the mounting slot extends to a jointing hole of the wrench body; the two side walls of the mounting slot extend inwards to form two slot top clamping surfaces; the anti-dropping part is arranged in the mounting slot of the wrench body; the pushing device is fixedly connected to one end of the anti-dropping part, and is used for horizontally pushing the anti-dropping part out of the mounting slot, so that the anti-dropping part extends to the jointing hole of the wrench body. According to the integrated wrench, two anti-dropping rods are adopted to prevent the nut from separating from the jointing hole of the wrench body; meanwhile, a rod body part of a screw passes through a gap between the two anti-dropping rods, so that the integrated wrench is especially suitable for an occasion with two nuts; the two anti-dropping rods not only can carry out anti-dropping on an auxiliary nut, but also do not affect the rod body part of the screw.
