Embodiment
Embodiment of the present utility model is described further below in conjunction with the accompanying drawings.
The specific embodiment of the assembly tooling of shunting switch of the present utility model, as shown in Figure 1 to Figure 3, wherein, 1 is support
Pawl, it is base that support claw 1, which includes radial direction support arm 11, vertical connection side 12 and pawl arm 13,2, and 3 be connecting shaft, and 4 be supporting plate, and 5 be bullet
Spring, 6 be nut.
Base 2 and connecting shaft 3 have collectively constituted support base, and one end of the remote base 2 of connecting shaft 3 is provided with external screw thread,
Nut 6 is installed with external screw thread, the top positioned at nut 6 of connecting shaft 3 is set with support claw 1.In the top of support claw 1 provided with support
Plate 4, supporting plate 4 is fixed in connecting shaft 3, in the present embodiment, and fixed form is welding, in other embodiments, can be used
Other modes are fixed, and are such as threadedly coupled.Guide rod is fixed with the lower surface of supporting plate 4（It is not drawn into figure）,
Guide rod runs through support claw 1, and spring 5 is provided with the outside of guide rod, and spring 5 is pressed between supporting plate 4 and support claw 1.
Support claw 1 is included in radial direction support arm 11 and the vertical connection side 12 being connected with radial direction support arm 11, the present embodiment, radially props up
The quantity of arm 11 is three, along the circumferentially-spaced arrangement of rotating shaft, and the quantity on vertical connection side 12 is three, and tap is corresponded to respectively and is opened
Three moving contacts closed, the upper end on connection side 12 is provided with pawl arm 13 vertically, and pawl arm 13 by connecting side 12 located at radially branch vertically
