Detailed description of the invention
Below in conjunction with specific embodiment, content of the present utility model is done the most specifically
Bright, a kind of embodiment of the present utility model is:
Embodiment 1:
As Figure 1-4, a kind of fan of frequency converter bearing extractor, base plate 1 is provided with extension
Portion 11, extension 11 one end is provided with notch 12, and notch 12 is provided with a shaft hole, base plate 1
Middle part is provided with screwed hole 13, and 3 suspension hooks 2 are rotationally connected with extension 11, and suspension hook is around screw thread
Axially bored line circle distribution, suspension hook 2 one end is J-type, and the other end is provided with rotation section 21, rotation section
21 is hinged with the shaft hole of extension 11, screw rod 3 and screwed hole 13 threaded engagement, top cap 4
