A fixing plate 202 is provided on the front of the threaded post 201, and is fixedly connected to the front of the threaded post 201. Four insertion blocks 203 are arranged in a rectangular array on the front of the fixing plate 202. The length of each insertion block 203 must be less than the thickness of the connecting hole on the connecting plate of the mechanism to be connected. All four insertion blocks 203 are fixedly connected to the front of the fixing plate 202. A limiting slide groove is symmetrically opened on the top of the fixing plate 202, and a limiting slide plate 204 is provided in the inner cavity of each of the two limiting slide grooves. The outer walls of the two limiting slide plates 204 are slidably sleeved with the inner cavities of the corresponding limiting slide grooves. Each of the two limiting slide plates 204 has a strip-shaped pressure plate 205 on its front side. The strip-shaped pressure plate 205 can move smoothly under the constraint of the limiting slide plates 204 and the limiting slide grooves. The two strip-shaped pressure plates 205 are fixedly connected to the front sides of the corresponding limiting slide plates 204. A strip-shaped rubber pad 6 is fixedly connected to the back side of the strip-shaped pressure plate 205. The strip-shaped rubber pad 6 serves a protective and fine-tuning function. The back side of the strip-shaped rubber pad 6 has evenly distributed friction textures to increase the friction coefficient between the strip-shaped rubber pad 6 and the inner cavity of the corresponding limiting slide groove. The friction between the connecting plates is such that a movable plate 206 is fitted onto the outer wall of the threaded column 201. A circular hole is provided in the center of the movable plate 206, which is fitted onto the outer wall of the threaded column 201 through the hole. Two strip-shaped pressure plates 205 are fixedly connected to the front of the movable plate 206. A fixed hexagonal collar 207 is provided on the back of the movable plate 206, movably fitted onto the outer wall of the threaded column 201. The fixed hexagonal collar 207 is fixedly connected to the back of the movable plate 206. A rotating hexagonal collar 208 is provided on the back of the fixed hexagonal collar 207. The inner surface of the rotating hexagonal collar 208... The outer wall of the threaded column 201 is threadedly connected to the wall.

The auxiliary rotating rod 7 is used to facilitate the worker to apply steering force to the rotating hexagonal collar 208. The outer wall of the auxiliary rotating rod 7 is provided with uniformly distributed anti-slip texture. The anti-slip texture is used to increase the friction between the auxiliary rotating rod 7 and the worker's palm.

The limiting block 5 is fixedly connected to the top of the fixed hexagonal collar 207.

[0026] Working principle of this utility model:

[0027] When installing a rectangular slot waveguide horn antenna, first ensure that the distance between the insertion block 203 and the strip pressure plate 205 is greater than the thickness of the connecting plate of the structure to be connected. Then, place the connecting plate of the structure to be connected between the strip pressure plate 205 and the fixing plate 202. During this process, the four insertion blocks 203 need to be inserted into the corresponding connecting holes on the connecting plate. Next, rotate the baffle 4 counterclockwise away from the top of the hexagonal collar 208. After the baffle 4 is completely disengaged from the top of the hexagonal collar 208, the auxiliary rotating rod 7 drives the hexagonal collar... The ring 208 rotates counterclockwise on the threaded post 201. The rotating hexagonal collar 208, which rotates counterclockwise on the threaded post 201, will drive the strip pressure plate 205 to move towards the fixed plate 202 through the rotating ring 209, the fixed hexagonal collar 207, the movable plate 206 and the limiting slide plate 204. When the rotating hexagonal collar 208 can no longer be rotated, the steering force applied to the auxiliary rotating rod 7 is removed and the baffle 4 is reset. At this time, the installation of the rectangular slot waveguide horn antenna is completed, reducing the cumbersomeness of installing the rectangular slot waveguide horn antenna.
