Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

As shown in fig. 1, the utility model provides an including fixed one-level screw fixation ware 4 that sets up on steel form 2, still include tertiary nut fixer with cap 6, be equipped with the through-hole on the 3 bottom surfaces of built-in fitting, the through-hole at the 3 bottom surfaces back of built-in fitting is stretched into inside 3 built-in fittings from the front end of tertiary nut fixer with cap 6, through 5 threaded connection of second grade no nut fixer between one-level screw fixation ware 4 and the tertiary nut fixer with cap 6.

Preferably, the first-stage screw fixer 4 and the third-stage cap nut fixer 6 are both provided with thread blind holes, and threads at two ends of the second-stage cap-free screw 5 are matched with the thread blind holes in the first-stage screw fixer 4 and the third-stage cap nut fixer 6.

Preferably, the primary screw fixing device 4 is connected with the steel moulding plate 2 in a welding mode.

According to the preferable scheme, through holes are formed in the positions, corresponding to the embedded parts 3, of the steel molding plate 2, and the first-stage screw fixing devices 4 penetrate through the through holes from the outer side of the steel molding plate 3 to the inner side of the steel molding plate 2.
