The adjusting mechanism 4 includes a double-rotation screw 401 rotatably installed in the cavity 2, and both sides of the double-rotation screw 401 are threadedly connected with a moving seat 402. A guide rod 403 is fixedly installed in the cavity 2. Specifically, two guide rods 403 are provided, and the two guide rods 403 are respectively arranged on both sides of the double-rotation screw 401, and the guide rods 403 penetrate The movable seat 402 is realized to limit the movable seat 402, two connecting seats 404 are fixedly installed on the bottom of the receiving pad 3, the two connecting seats 404 correspond to the two movable seats 402 one by one, and a connecting rod 405 is movably installed between the connecting seat 404 and the movable seat 402, a fixing plate 7 is fixedly installed on the side wall of the fixed base 1, a motor 6 is arranged on the outer side of the fixed base 1, the motor 6 is fixedly installed on the fixing plate 7, and the output shaft of the motor 6 is connected to the double-rotation screw 401, when in use, the motor 6 is started to realize the rotation of the double-rotation screw 401.

[0023] When in use, the operator starts the motor 6, and the motor 6 drives the double-rotation screw 401 to rotate. During the rotation of the double-rotation screw 401, the movable seats 402 on both sides move toward or away from each other, and under the connecting action of the connecting rod 405, the receiving pad 3 moves longitudinally.

[0024] See attached Figure 1-Figure 3Two longitudinal brackets 8 are fixedly installed in parallel on the top of the receiving pad 3, an arc-shaped slide 9 is fixedly installed on the top of the longitudinal bracket 8, an arc-shaped bracket 10 is slidably connected in the arc-shaped slide 9, an antenna mounting plate 11 is fixedly installed on the top of the two arc-shaped brackets 10, a screw 12 is threadedly connected on the arc-shaped slide 9, a clamping plate 13 is fixedly installed on the inner side of the screw 12, and a hand wheel 14 is fixedly installed on the outer side of the screw 12.
