[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] like Figures 1 to 6 As shown, this is the first embodiment of the utility model, which provides a Bluetooth module testing fixture, including a workbench 1, a testing mechanism 2 provided on the top of the workbench 1, a clamping component 3 provided in the inner cavity of the workbench 1, and an adjustment structure 4 provided inside the clamping component 3.

[0026] The clamping assembly 3 includes a connecting rod 304, the outer side of which is connected to the inside of the workbench 1, and a movable plate 303 is provided on the outer surface of the connecting rod 304.

[0027] The adjustment structure 4 includes a movable frame 401, the outer side of which is movably connected to the inner wall of the movable plate 303. A toothed block 403 is provided on the top of the movable frame 401, and teeth 405 are provided on the inner wall of the movable plate 303. The outer surface of the teeth 405 is engaged with the top of the toothed block 403. A pressure rod 404 is provided on the top of the toothed block 403. The top of the pressure rod 404 extends to the outer side of the worktable 1, and a clamping block 406 is provided on the inner side of the pressure rod 404.

[0028] By pressing the pressure rod 404, the pressure rod 404 is moved downward, thereby separating the tooth block 403 from the tooth 405, thus releasing the pressure rod 404 from the movable plate 303. Then, the position of the clamping block 406 on the movable plate 303 is adjusted according to the size of the Bluetooth module, so that the clamping block 406 is moved to the force point of the module to avoid unstable fixation. Then, by activating the clamping assembly 3, the movable plate 303 is moved on the outer surface of the connecting rod 304, and the adjusted clamping block 406 is used to fix the Bluetooth module of different sizes, so as to prevent unstable fixation during testing from affecting accuracy.

[0029] Example 2

[0030] like Figure 3 and Figure 6 As shown, this embodiment includes the features of embodiment 1. The distinguishing technical feature is that the clamping assembly 3 includes a drive motor 301. The outer side of the drive motor 301 is connected to the inner wall of the worktable 1. The drive motor 301 drives a double threaded rod 302. The two sides of the outer surface of the double threaded rod 302 are threadedly connected to the inner wall of the movable plate 303.

[0031] Start the drive motor 301, which drives the movable plate 303 to move on the outer surface of the connecting rod 304 via the double threaded rod 302. In turn, the movable plate 303 drives the adjustment structure 4 as a whole, so that it clamps and fixes the Bluetooth module placed on the top of the workbench 1 for testing.

[0032] There are four movable plates 303, which are located at the four sides of the center of the workbench 1.

[0033] By distributing four movable plates 303 around the center of the workbench 1, the Bluetooth module is clamped and fixed around its perimeter to prevent it from shifting position during testing.

[0034] Among them, a limiting block 402 is provided at the bottom of the tooth block 403, and the outer surface of the limiting block 402 is movably connected to the inner cavity of the movable frame 401;

[0035] When the engagement between the tooth block 403 and the tooth 405 is released, the pressure rod 404 is moved, which causes the limiting block 402 on the tooth block 403 to move within the cavity of the movable frame 401. Through the cooperation of the movable frame 401 and the limiting block 402, the tooth block 403 will not detach from the movable frame 401 when it moves, which facilitates the subsequent reset of the tooth block 403 and its re-fixation.

[0036] Among them, a protective pad 407 is provided on the outside of the clamping block 406, and the protective pad 407 is made of rubber;

[0037] When the clamping component 3 is activated, it causes the clamping block 406 to clamp the Bluetooth module from all sides. At this time, the protective pad 407 on the outside of the clamping block 406 deforms, which cushions the Bluetooth module from all sides and prevents damage to the Bluetooth module during the clamping process.

[0038] Among them, the bottom of the movable frame 401 is provided with a spring 408, and the other end of the spring 408 is connected to the inner wall of the movable plate 303;

[0039] At this time, since the spring 408 is in a compressed state, it will apply upward pressure to the movable frame 401, thereby driving the movable frame 401 to move upward as a whole, so that the top of the tooth block 403 engages with the outer surface of the tooth 405, thereby fixing the tooth block 403 as a whole, which makes it convenient to clamp Bluetooth modules of different sizes.

[0040] Among them, the outer surface of the movable frame 401 is movably sleeved with the inner wall of the movable plate 303, and the size of the movable frame 401 is adapted to the inner cavity of the movable plate 303;

[0041] When the pressure rod 404 is pressed, the pressure rod 404 drives the toothed block 403, the movable frame 401 and the clamping block 406 to move downward. The movable frame 401 moves along the inner cavity of the movable plate 303 and squeezes the spring 408. Since the movable frame 401 is matched with the size of the movable plate 303, it prevents the movable frame 401 from shifting when squeezed, which would affect the subsequent reset of the movable frame 401.

[0042] Working principle and usage process of this utility model:

[0043] First, when the operator tests Bluetooth modules of different sizes, pressing the pressure rod 404 causes the toothed block 403 to separate from the toothed teeth 405, releasing their fixation. Then, pulling the pressure rod 404 moves the toothed block 403 and the clamping block 406 to the appropriate position. After releasing the pressure rod 404, the spring 408 causes the movable frame 401 to move upward, causing the toothed block 403 and toothed teeth 405 to re-engage and fix the adjusted pressure rod 404. At the same time, the other pressure rods 404 are adjusted to move the clamping block 406 to the position where the composite Bluetooth module is snapped in, avoiding inaccurate snapping. Then, the drive motor 301 is started, which moves the movable plate 303 through the double threaded rod 302, causing the adjusted clamping block 406 to fix the Bluetooth modules of different sizes, preventing unstable fixation from affecting the accuracy of the test, improving the practicality of the device and bringing convenience to the operator.
