[0026] In this embodiment, by setting a locking block 204, when the protective sleeve is put on the flange 203, the locking block 204 will be inserted into the locking groove on the flange 203, thereby locking the flange 203 to prevent the flange 203 and the waveguide from rotating and displacing in the protective sleeve.

[0027] Specifically, the connection relationship between the flange 203 and the locking block 204 is a snap connection.

[0028] In this embodiment, by providing a locking block 204 , when one end of the locking block 204 is moved out of the locking groove on the flange 203 , the flange 203 can be unlocked.

[0030] In this embodiment, a limit rod 602 is set, and the screw rod 604 is rotated by turning the knob 605.

The rotating screw rod 604 drives the limiting rod 602 to move laterally through the nut seat 603. When one end of the limiting rod 602 is inserted into the limiting hole on the insert block 601, the locking sleeve 6 can be limited, thereby realizing the installation of the locking sleeve 6.
