The invention relates to the related field of pre-embedded sleeves, in particular to a pre-embedded sleeve with an anti-loosening structure, which comprises a split pre-embedded sleeve, a plurality of solidified soft capsules and a piercing piece, the split pre-embedded sleeve comprises a pre-embedded base and a sleeve body, and a first screw hole used for being in threaded connection with a bolt is formed in one end, far away from the pre-embedded base, of the sleeve body; the end of the cylinder body is also connected with a temporary sealing cover; the puncturing piece comprises an elastic deformation part and a puncturing tip part, and the elastic deformation part elastically deforms after being pressed by the head end of the bolt and drives the puncturing tip part to puncture and solidify the soft capsule. According to the two embedded sleeves, after the bolt is completely screwed into the embedded sleeves, the puncturing part is triggered to puncture the curing soft capsule and enable ...
