[0003] In the prior art, multi-channel matrix antennas are often manually held for flexibility. However, manual holding can cause slight shaking, and prolonged testing can lead to arm pain. Furthermore, manual holding is not flexible or convenient in test environments where standing is unsuitable, such as muddy ground or deep grass. Utility Model Content

[0006] The arc-shaped shell is provided with three arc-shaped shells and is movably connected to the card seat. The movable legs are slidably connected in the arc-shaped shells. The movable legs are equipped with limiters. The limiters restrict the movable legs from sliding in the arc-shaped shells, which can change the height of the sensor and also facilitate holding the movable legs to lift the sensor;

[0007] A reinforcement cover is provided at the lower part of the inner wall of the arc-shaped shell, and the movable leg is inserted between the arc-shaped shell and the reinforcement cover, thereby improving the telescopic stability of the movable leg and preventing it from becoming loose.

[0008] Furthermore, the connector includes a base and an elastic sheet installed on the base, the sensor is located between the elastic sheets, and a rubber pad is provided on the surface of the elastic sheet. The rubber pad presses against the sensor, and the rubber pad has sufficient friction on the sensor to prevent the sensor from falling.

[0009] Furthermore, a connecting ear is provided at the upper end of the arc-shaped shell, and the connecting ear is rotatably connected to a transfer seat, and the transfer seat is fixedly connected to the clamping seat through a universal ball. The universal ball can change the angle of the sensor, making it easier to lift the sensor and adapt to more environments.

[0010] Furthermore, the limiter includes a stud, which is fixedly connected to the movable leg and passes through a bar hole on the surface of the arc-shaped shell. A handle nut is screwed onto the stud and rests against the arc-shaped shell. An elastic ring is sleeved on the stud and contacts the arc-shaped shell. By turning the handle nut, the sliding of the movable leg can be limited, and the height of the sensor can be changed conveniently.

[0011] Compared with the existing technology, the beneficial effects of the utility model are: the sensor can be quickly clamped on the elastic sheet, and the arc shell can be rotated to open to support the sensor above the ground. There is no need to manually hold the sensor, which is convenient for using the sensor in complex environments and has a wider adaptability. After loosening the handle nut, pull the movable leg, and the movable leg can increase the lifting height of the sensor. The three arc shells are merged into a column, which is convenient for holding the movable leg or the arc shell. With the universal ball, the sensor can be manually lifted into the air and the angle can be adjusted, providing more diverse usage methods. BRIEF DESCRIPTION OF THE DRAWINGS

The movable leg 8 is installed with a limiter. The limiter limits the sliding of the movable leg 8 in the arc-shaped shell 6. Pulling the movable leg 8 changes the telescopic length of the movable leg 8 from the arc-shaped shell 6. The limiter is used to maintain the position of the movable leg 8;

[0023] A reinforcement cover 9 is provided at the lower portion of the inner wall of the arc-shaped shell 6 , and the movable leg 8 is inserted between the arc-shaped shell 6 and the reinforcement cover 9 .

[0025] In this embodiment, if Figure 1 and Figure 3 As shown, a rubber pad 13 is provided on the surface of the elastic sheet 12 , and the rubber pad 13 presses against the sensor 1 . The rubber pad 13 can hold the sensor 1 more firmly, and the sensor 1 is not easily separated from the elastic sheet 12 , thereby preventing the sensor 1 from being damaged.
