[0002] A vehicle-mounted antenna is an antenna device installed on a car or other vehicle for receiving and sending radio frequency signals. During the production process, the vehicle-mounted antenna needs to be polished. In the existing vehicle-mounted antenna polishing device, due to the length of the vehicle-mounted antenna, it does not need to be clamped and fixed, but the vehicle-mounted antenna can be moved after clamping. The sizes of vehicle-mounted antennas are different, so the clamping distance of the clamping mechanism needs to be adjusted. However, in the existing technology, when the clamping mechanism adjusts the spacing, its clamping center will change, and then the polishing mechanism of the polishing device needs to be adjusted at the same time. At this time, a clamping mechanism for a vehicle-mounted antenna polishing device is needed to solve the problem of the above-mentioned clamping center change. Utility Model Content

In the existing vehicle-mounted antenna polishing processing device, due to the length of the vehicle-mounted antenna, it is not necessary to clamp and fix it, but the vehicle-mounted antenna can be moved after clamping. The sizes of vehicle-mounted antennas are different, so it is necessary to adjust the clamping distance of the clamping mechanism. However, in the prior art, when the clamping mechanism adjusts the spacing, its clamping center will change, and then the polishing mechanism of the polishing device needs to be adjusted at the same time. Based on this, a clamping mechanism for a vehicle-mounted antenna polishing device is provided.

[0005] As a preferred implementation, through holes are provided on both sides of the fixing shell, and the row of teeth are located inside the through holes.

[0006] As a preferred implementation manner, the top of the connecting plate is flush with the top of the fixing shell, and the bottom of the supporting plate is in contact with the top of the fixing shell.

[0007] As a preferred embodiment, a sleeve plate is fixedly mounted on the outer surface of the row of teeth by bolts, one side of the sleeve plate is fixedly connected to the outer surface of the fixed shell, and the row of teeth is meshingly connected to the gear.

[0008] As a preferred embodiment, two telescopic frames are fixedly connected to the bottom of the platform, and a limiting plate is fixedly connected between the bottoms of the two telescopic frames.

[0009] As a preferred implementation, a limiting hole is provided on the top of the limiting plate, and the inner wall of the limiting hole is slidably connected to the outer surface of the support rod.

[0010] Compared with the prior art, the advantages and positive effects of the utility model are as follows: through the cooperation of the gear and the row of teeth, two rows of teeth in opposite directions are arranged around the gear, so that the two rows of teeth can achieve simultaneous braking through the gear, when one row of teeth moves, the other row of teeth will also move, and the two rows of teeth are exactly the same, so that the two rows of teeth can move at the same time, and the moving distances can be the same, so that the moving distances of the two connecting plates can be the same, so that the moving distances of the two support plates can be the same, and the bottom of the support plate is in contact with the top of the fixed shell, so that the support plate can be supported by the fixed shell, and the clamping roller is ladder-shaped. When the two clamping rollers are in contact with each other, different step positions can control vehicle-mounted antennas of different sizes. The wire is clamped, and the row of teeth and the gear can make the two clamping rollers present the same moving distance, so that in use, the clamping center can be fixed when the clamping roller is adjusted, thereby increasing the working stability of the polishing platform, and the distance between the two clamping rollers can be adjusted according to needs through the bottom of the clamping roller, thereby clamping vehicle antennas of different models and special models, and the moving distance of the row of teeth can be limited by the sleeve plate to increase the structural stability of the equipment.
