[0025] Example 2

[0026] Reference Figure 1-4 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0027] In this embodiment, there are three connection ends 2 , which are respectively installed on the front and both sides of the waveguide circulator body 1 , and the inner cavity of the connection end 2 is communicated with the inner cavity of the waveguide circulator body 1 .

[0028] The fixing block 31 is fixedly connected to the connecting end 2, and the positioning hook 33 is threadedly connected to the connecting device through bolts.

[0029] The connecting assembly 32 includes a connecting plate 321 , a movable plate 322 , a spring 323 and a cross bar 324 . One end of the connecting plate 321 is movably connected to the fixing block 31 via a movable pin, and the movable plate 322 is located at one side of the connecting plate 321 .

[0030] The cross bar 324 is located in the inner cavity of the positioning hook 33 and is engaged with the inner cavity of the positioning hook 33 . Both ends of the cross bar 324 are fixedly connected to the movable plate 322 . The spring 323 is sleeved on the surfaces of the movable plate 322 and the connecting plate 321 .

[0031] The limiting assembly 34 includes a limiting block 341 and a limiting groove 342. The limiting groove 342 is opened on the surface of the connecting plate 321. One end of the limiting block 341 extends to the inner cavity of the limiting groove 342 and is slidably connected to the inner cavity of the limiting groove 342. The other end of the limiting block 341 is fixedly connected to the movable plate 322.

[0032] like Figure 1-4 As shown, the positioning hook 33 is fixed to the external device by bolts, and then the external device is connected to the connecting end 2, the front end connecting end 2 is the load end, one side connecting end 2 is the input end, and the other side connecting end 2 is the output end, the external device is connected to the corresponding connecting end 2, and then the cross bar 324 is pulled, and the cross bar 324 drives the movable plate 322 to move when the cross bar 324 moves, and the movable plate 322 drives the limit block 341 to move along the inner cavity of the limit groove 342 when the movable plate 322 moves.

[0033] When in use, first fix the positioning hook 33 to the external device with bolts, then connect the external device to the corresponding connecting end 2, and then pull the cross bar 324. When the cross bar 324 moves, it drives the movable plate 322 to move. When the movable plate 322 moves, it drives the limit block 341 to move along the inner cavity of the limit groove 342. The limit groove 342 and the limit block 341 cooperate to limit the movement trajectory of the movable plate 322. While the cross bar 324 drives the movable plate 322 to move, it squeezes the spring 323, causing the spring 323 to deform under the force, and the cross bar 324 is clamped in the inner cavity of the positioning hook 33. The restoring elastic force of the spring 323 can form a pulling force, so that the cross bar 324 is tightly fitted with the inner cavity of the positioning hook 33, thereby fixing the connected equipment to prevent loosening.
