[0043] Limiting groove 303: The limiting groove 303 is formed on the upper surface of the base 1, and the inner wall of the limiting groove 303 is slidably connected to the outer surface of the stroke rod 302.

[0044] refer to Figure 3 As shown, a support assembly 4 is provided on the lower end face of the stroke rod 302. The support assembly 4 includes:

[0045] First slide groove 401: First slide groove 401 is formed on the inner wall of base 1;

[0046] Support plate 402: The upper surface of the support plate 402 is slidably connected to the inner wall of the first groove 401;

[0048] Using the above scheme: the support plate 402 rotates along the inner wall of the first slide groove 401, and the support plate 402 drives the upper surface stroke groove 403 to move circumferentially, so that the inner wall of the stroke groove 403 presses against the outer surface of the stroke rod 302, so that the stroke rod 302 moves inward along the inner wall of the stroke groove 403, and the stroke rod 302 drives the fixing block 301 to approach the crystal oscillator along the inner wall of the limiting groove 303, so that the fixing block 301 is in close contact with the crystal oscillator.

[0049] refer to Figure 3 As shown, a transmission assembly 5 is provided on the outer surface of the support disk 402. The transmission assembly 5 includes:

[0050] Toothed ring 501: The inner ring of toothed ring 501 is fixedly connected to the outer surface of support plate 402;

[0051] Gear 502: The outer surface of gear 502 is meshed with the outer surface of gear ring 501, and a drive assembly 6 is provided on the lower surface of gear 502.

[0052] The above scheme is adopted: In order to make the support disk 402 rotate, the gear 502 rotates. The gear 502 can mesh with the gear ring 501, so that the gear ring 501 drives the support disk 402 to rotate.

[0053] refer to Figure 4 As shown, the driving component 6 includes:

[0054] Threaded rod 601: The upper end face of threaded rod 601 is fixedly connected to the lower surface of gear 502;

[0056] Transmission block 603: The inside of transmission block 603 is connected to the outer surface of threaded rod 601 by a threaded rotation.

[0057] The above scheme is adopted: In order to make the gear 502 rotate, the servo motor 602 drives the threaded rod 601 to rotate, and the threaded rod 601 drives the gear 502 to rotate. At the same time, the threaded rod 601 can drive the transmission block 603 to move downward through the thread.

[0058] refer to Figure 4 As shown, a push-out component 7 is provided on the left surface of the transmission block 603. The push-out component 7 includes:

[0059] Connecting rod 701: The right end face of connecting rod 701 is fixedly connected to the left surface of transmission block 603, and the outer surface of connecting rod 701 is slidably connected to the inner wall of support plate 402 and the upper surface of base 1.

[0060] Support plate 702: The lower surface of support plate 702 is fixedly connected to the upper end face of connecting rod 701.

[0061] Using the above scheme: when the transmission block 603 moves down, the transmission block 603 can drive the support plate 702 to move down through the connecting rod 701, so as to place the crystal oscillator on the upper surface of the support plate 702 on the upper surface of the base 1.

[0062] refer to Figure 2 As shown, the inner wall of the base 1 is provided with a second sliding groove 8, and the inner wall of the second sliding groove 8 is slidably connected to the right surface of the transmission block 603.

[0063] Using the above scheme: the second slide 8 mainly serves to limit the movement of the transmission block 603.

[0064] refer to Figure 2As shown, a support member 9 is provided on the outer surface of the threaded rod 601. There are two support members 9. The interior of the two support members 9 is rotatably connected to the outer surface of the threaded rod 601 through bearings. The right surface of the support member 9 is fixedly connected to the inner wall of the base 1.

[0065] Using the above scheme: Support member 9 mainly serves to support threaded rod 601.

[0066] The working principle of this utility model:

[0067] In use, the crystal oscillator is placed on the support plate 702. The servo motor 602 drives the threaded rod 601 to rotate. The threaded rod 601 drives the transmission block 603 to move downward through the thread. The transmission block 603 drives the support plate 702 to move downward through the connecting rod 701 until the support plate 702 enters the base 1, so that the crystal oscillator on the upper surface of the support plate 702 is placed on the upper surface of the base 1. At the same time, the threaded rod 601 drives the gear 502 to rotate. The gear 502 can interact with the gear ring 501. The meshing causes the gear ring 501 to drive the support plate 402 to rotate along the inner wall of the first slide groove 401. The support plate 402 drives the upper surface stroke groove 403 to move circumferentially, causing the inner wall of the stroke groove 403 to press against the outer surface of the stroke rod 302. This causes the stroke rod 302 to move inward along the inner wall of the stroke groove 403. The stroke rod 302 drives the fixing block 301 to approach the crystal oscillator along the inner wall of the limiting groove 303, making the fixing block 301 fit tightly against the crystal oscillator. Finally, the detector 2 is operated to test the crystal oscillator.

[0068] After the test is completed, the servo motor 602 rotates in the opposite direction, which pushes the support plate 702 upward to push the crystal oscillator. At the same time, the fixing block 30 does not stick to the crystal oscillator, so that the crystal oscillator can be pushed out and then removed.

[0069] It should be noted that the servo motor 602 is a device or equipment existing in the prior art, or a device or equipment that can be implemented by the prior art, and the specific composition and principle of the power supply of the servo motor 602 are clear to those skilled in the art, so they will not be described in detail here.

[0070] In summary, this auxiliary fixing assembly for crystal oscillator testing, through the fixing assembly 3, support assembly 4, transmission assembly 5, drive assembly 6, push-out assembly 7, second slide 8, and support member 9, solves the problem that the crystal oscillator under test is prone to displacement or shaking due to the lack of limiting and fixing of the crystal oscillator in the device, resulting in unstable detection signals and large errors in measured parameters such as frequency and amplitude.
