[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Example 1

[0020] See also Figure 1-4 The embodiment of the present invention provides a low-noise amplifier test fixture base, including a base 1 and an anti-interference shell 8. The top surface of the base 1 is rotatably connected to the rotating plate 2, and the top surface of the rotating plate 2 is symmetrically fixed with a fixed rod 14. The anti-interference shell 8 is arranged above the rotating plate 2, and the two ends of the anti-interference shell 8 are respectively sleeved on the rod wall of the fixed rod 14. The diameter of the anti-interference shell 8 is equal to the diameter of the rotating plate 2. When the equipment to be tested is placed on the rotating plate 2, the reciprocating motor 12 is turned on to rotate the screw rod 10, so that the moving block 11 can be easily driven to move up and down, so that the moving block 11 drives the anti-interference shell 8 to move upward. At this time, the equipment to be tested can be conveniently placed on the rotating plate 2, and then the screw rod 1 is reciprocated by the reciprocating motor 12. 0 is rotated in the opposite direction to move the moving block 11 downward until the bottom surface of the anti-interference shell 8 is in contact with the top surface of the rotating plate 2. The side wall of the rotating plate 2 is fixedly installed with a U-shaped rod 9, and the internal rotation of the U-shaped rod 9 is connected to the screw rod 10. The top of the U-shaped rod 9 is fixedly installed with a reciprocating motor 12. The output shaft of the reciprocating motor 12 is fixedly connected to the upper end of the screw rod 10 by passing through the top surface of the U-shaped rod 9. The left side wall of the anti-interference shell 8 is fixedly installed with a moving block 11, and the moving block 11 is threadedly sleeved on the rod wall of the screw rod 10. The right side wall of the U-shaped rod 9 does not contact the side wall of the anti-interference shell 8. After the equipment to be tested is placed, the screws 13 on both sides are rotated respectively so that the clamping block 5 can conveniently clamp the equipment to be tested, so that its position can be more stable.

[0021] Example 2

[0022] In order to facilitate the stability of the position of the test equipment and to facilitate the testing thereof, in this embodiment, as Figure 2-4 As shown, the side walls at both ends of the anti-interference shell 8 are symmetrically threaded with screws 13, and the interior of the anti-interference shell 8 is symmetrically provided with clamping blocks 5. The ends of the two screws 13 are respectively connected to the side walls of the clamping blocks 5 by passing through the inside of the side walls of the anti-interference shell 8. When the clamping blocks 5 are at the water level position, the bottom surface of the clamping blocks 5 is horizontal with the bottom surface of the anti-interference shell 8. When clamping the equipment, the clamping blocks 5 at this time can form a horizontal position at any angle, thereby facilitating the rotation of the screws 13, and the outer side walls of the rotating plate 2 are fixed at equal intervals. It is equipped with a gear block 3, and a mounting frame 4 is fixedly installed on the upper end of the base 1. A gear 6 is rotatably connected between the top surface of the mounting frame 4 and the base 1. The rotating plate 2 is meshed with the gear 6 through the gear block 3. A rotating motor 7 is fixedly installed on the upper end of the mounting frame 4. The output shaft of the rotating motor 7 is fixedly connected to the top of the gear 6 by passing through the interior of the mounting frame 4. When the rotation orientation of the equipment to be tested is detected, the rotating motor 7 is turned on to rotate the gear 6, which drives the rotating plate 2 to rotate, so that the equipment to be tested placed inside is rotated.

[0023] It should be noted that, in this embodiment, when using the low noise amplifier test fixture base, Figure 1-4 As shown, when the device to be tested is placed on the rotating plate 2, the reciprocating motor 12 is turned on to make the screw rod 10 rotate, thereby conveniently driving the moving block 11 to move up and down, and making the moving block 11 drive the anti-interference shell 8 to move upward. At this time, the device to be tested can be conveniently placed on the rotating plate 2, and then the reciprocating motor 12 is used to rotate the screw rod 10 in the opposite direction again to move the moving block 11 downward until the bottom surface of the anti-interference shell 8 is in contact with the top surface of the rotating plate 2. Then, the screw rods 13 on both sides are rotated respectively so that the clamping block 5 can conveniently clamp the device to be tested, so that its position can be more stable. When the rotation orientation of the device to be tested is detected, the rotating motor 7 is turned on to make the gear 6 rotate, driving the rotating plate 2 to rotate, so that the device to be tested placed inside is rotated, which is convenient for testing the device to be tested.
