The limit seal cover 28 is in threaded connection with the upper end of the cylindrical accommodating groove 24 and cannot move, so that the spring 29 elastically presses the pressing circular plate 27 downwards, and the pressing circular plate 27 presses the lower end of the curing soft capsule 6 at the inverted truncated cone-shaped structure of the cylindrical accommodating groove 24, and accordingly the following soft long strip plate 26 can be ensured to collide and puncture the curing soft capsule 6 after extending.

The barrel 2 is internally molded with a plurality of guide grooves which are in one-to-one correspondence with a plurality of soft long strips 26, the lower ends of the guide grooves downwards protrude out of the step parts, the upper ends of the guide grooves upwards extend and are communicated to the inverted round table-shaped structure of the cylindrical accommodating groove 24, the elastic deformation parts 7 are disc structures with the middle parts protruding upwards, the lower ends of the soft long strips 26 are upwards raised and connected to the elastic deformation parts 7, and the upper ends of the soft long strips 26 are molded with pointed structures.

The guide groove is not shown in the figure, the elastic deformation part 7 and the puncture tip part are in the structures shown in fig. 11 and 15, after the elastic deformation part 7 is extruded downwards to deform, a plurality of soft long strips 26 are driven to extend upwards along the guide grooves until the upper ends of the soft long strips 26 extend into the cylindrical accommodating groove 24 and puncture the solidified soft capsules 6, and the soft long strips 26 are made of soft materials, so that the soft long strips can be conveniently inserted into the guide groove, but also have certain hardness, and the soft long strips can be ensured to extend out of the guide groove and puncture the solidified soft capsules 6 through the tip structure.

Because the space state before the sleeve in the concrete segment is screwed into the bolt is not fixed, namely, when the bolt is screwed in, the bolt can be screwed into the sleeve from top to bottom, and also can be screwed into the sleeve from bottom to top, the invention designs two embedded sleeves for coping with different states, namely, the bolt is screwed into the embedded sleeve from bottom to top in the first embodiment, and the bolt is screwed into the embedded sleeve from top to bottom in the second embodiment.

The foregoing examples merely illustrate one or more embodiments of the invention, which are described in greater detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention.
