Preferably, the screw bases with different sizes and different models comprise a base screw base and other screw bases with different sizes and different models; the shape and the position of the exposed surface of the base screw rod base correspond to the positions and the shapes of hollow grooves in screw rod bases of different sizes and different types, and the base screw rod base and the hollow grooves can be seamlessly embedded and sleeved in an embedded mode; and the base of the basic screw rod is in screw-in type splicing with the middle part of the basic threaded screw rod.
Preferably, the middle parts of the threaded screws with different sizes comprise the middle part of a basic threaded screw and the middle parts of threaded screws with different sizes and different models; the shape and the position of the exposed surface in the middle of the basic threaded screw correspond to the positions and the shapes of the hollow grooves in the middle of the threaded screws with different sizes, and the two can be spirally screwed in and spliced.
Preferably, the screw heads with different sizes and different models comprise a through connection combined shaft, a basic screw head and other screw heads with different sizes and different models; the shape and the position of the exposed surface of the head of the basic screw correspond to the positions and the shapes of hollow grooves in heads of screws with different sizes and models, and the exposed surface and the hollow grooves can be seamlessly embedded and sleeved in an assembled mode; the head of the basic screw rod is in screw-in type splicing with the middle of the basic threaded screw rod; the through connection combination shaft is buckled and fixed with screw heads of different sizes and different models.
Compared with the prior art, the utility model has the beneficial effects that: the utility model discloses use basic screw rod as the basic point, with the seamless nested formula amalgamation of inlaying of other different size different model screw rods, can realize exchanging between different size different models. Other screws with different sizes and different models are designed in an inner hollow groove mode, so that materials required for producing the screw group are greatly reduced, and the production cost is greatly reduced. And simultaneously, the utility model discloses it is the spiral formula amalgamation of screwing in to each intersegment, supports tightly each other between each section, can the dismouting trade between each intersegment. Meanwhile, the head of the screw rod is in through buckling connection by adopting a through connection combined shaft. The firm stability of screw rod group has been strengthened greatly.
Drawings
FIG. 1 is a schematic structural diagram of the present invention
Reference numbers in the figures: the screw rod comprises a basic screw rod base 1, screw rod bases 2 with different sizes and different models, a basic threaded screw rod middle part 3, screw rod middle parts 4 with different sizes and different models, basic screw rod heads 5, screw rod heads 6 with different sizes and different models and a penetrating connection combined shaft 7
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in figure 1, the utility model provides a screw group with firm fixation, which comprises a screw head part which is connected with a combined shaft in a penetrating way, and the screw group is assembled and spliced by screw bases with different sizes and different models, screw middle parts with different sizes and different threads and screw heads with different sizes and different models in a seamless embedding and sleeving way. The base screw base 1, the middle part 3 of the base threaded screw and the head part 5 of the base threaded screw are mutually screwed and spliced and are mutually abutted. The user carries out seamless inlaying and nesting type assembling and splicing to screw bases 2 of different sizes and different models, threaded screw middle parts 4 of different sizes and different models, screw heads 6 of different sizes and different models respectively according to production needs, and all the sections can be disassembled and assembled for replacement. The through connection combination shaft 7 is fastened on the head of the screw.
The technical principle is as follows:
the firmly fixed screw group takes the basic screw as a base point, and can be seamlessly embedded and sleeved with other screws with different sizes and models to realize the interchange among the screws with different sizes and models. Other screws with different sizes and different models are designed in an inner hollow groove mode, so that materials required for producing the screw group are greatly reduced, and the production cost is greatly reduced.
