Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides a simple verticality testing fixture, as shown in Figures 1-5, including a connecting base plate 1 and a central connecting post 2 located in the middle of the connecting base plate 1; an outer connecting post 9 located on the upper side of the connecting base plate 1 near the side; a central threaded post 8 located in the middle of the outer connecting post 9; an inner telescopic connector 10 located at the bottom of the central threaded post 8; a central connecting shaft 11 located between the central threaded post 8 and the inner telescopic connector 10; a connecting vent pipe 12 located at the bottom of the inner telescopic connector 10; a telescopic connecting groove 17 located at the end of the connecting vent pipe 12 and within the central connecting post 2; and a connecting piston body 16 located in the middle of the telescopic connecting groove 17. A telescopic connecting column 15 is provided on the side of the piston body 16, and an arc-shaped moving extrusion block 14 is provided on the side of the telescopic connecting column 15. In use, the upper connecting knob 7 is rotated to cause the central threaded column 8 to extrude the inner telescopic connecting body. After being extruded, the inner telescopic connecting body is compressed, and the gas inside it enters the telescopic connecting groove 17. Because of the gas entering the connecting piston body 16, the telescopic connecting column 15 and the arc-shaped moving extrusion block 14 will move. After the arc-shaped moving extrusion block 14 moves outward, it can contact the inner wall of the external measuring stator 6. Since the arc-shaped moving extrusion block 14 is adjustable, it can adapt to measuring stators 6 with different inner diameters, thereby effectively improving the practicality of the simple verticality detection fixture.

[0025] As shown in Figure 5, a side-connecting rubber layer 13 is provided on the side of the arc-shaped moving extrusion block 14. The side-connecting rubber layer 13 is connected to the arc-shaped moving extrusion block 14 by adhesive. The side-connecting rubber layer 13 can increase the friction between the arc-shaped moving extrusion block 14 and the measuring stator 6, thereby improving the stability of the connection.

[0026] As shown in Figures 1 and 2, an upper connecting knob 7 is provided on the upper side of the central threaded post 8. The outer side of the upper connecting knob 7 is textured, which increases the friction with the user's hand, thus making it easier for the user to rotate the knob.

[0027] As shown in Figures 1 and 2, a verticality outer ring 3 is provided on the side of the central connecting column 2. The verticality outer ring 3 is installed and connected to the connecting base plate 1 by a snap-fit ​​method. The measuring stator 6 is placed in close contact with the top surface of the verticality outer ring 3, and the measuring stator 6 is fitted with the inner wall.

[0028] As shown in Figures 1 and 2, an L-shaped backing surface 5 is provided on the side of the verticality outer ring 3. The L-shaped backing surface 5 is placed horizontally with the connecting base plate 1. An L-shaped backing measuring surface 4 is provided on the upper side of the L-shaped backing surface 5. The L-shaped backing measuring surface 4 is placed perpendicular to the L-shaped backing surface 5, and the L-shaped backing measuring surface 4 and the L-shaped backing surface 5 are an integral structure. After measuring the verticality of the stator 6 by placing the L-shaped backing measuring surface 4 flat, it is rotated one full circle to use the verticality dimension of the L-shaped backing measuring surface 4.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
