[0025] As Figures 1-6As shown, the utility model provides a technical solution: a wireless radio frequency module test bracket, comprising a base 1 and a clamping block 2, the clamping blocks 2 are symmetrically arranged, and the bottom ends of the clamping blocks 2 are fixedly connected to a group of symmetrical guide blocks 3, the top end of the base 1 is fixedly connected to two groups of symmetrical slide grooves 4, the guide blocks 3 are movably connected to the inside of the slide grooves 4, the clamping block 2 is movably connected to the top end of the base 1 through the guide blocks 3, the cross-section of the clamping block 2 is trapezoidal, the top end of the base 1 is fixedly connected to a clamping mechanism 5, and the clamping mechanism 5 is fixedly connected to the back side of the clamping block 2, The bottom end of the block 2 is fixedly connected to the limiting column 6, and the point of the limiting column 6 is movably connected to the support rod 7.

Then, by rotating the adjusting rod 11, the moving block 10 is driven to move inside the clamping block 2, thereby driving the baffle 9 to move to the end of the module, thereby resisting the third end of the module. Then, the servo motor 508 is started to drive the driving rod 507 to rotate, so that the slider 506 moves inside the base 1, so that the traction rope 505 moves, pulling the connecting plate 504 close to the fixed plate 501, so that the clamping block 2 tightly clamps the module; then, the control block 805 is moved downward, and under the action of the control rope 806, the driving block 804 moves downward, and the inclined surface of the inner bottom end of the driving block 804 and the inclined surface of the pushing block 802 squeeze each other, so that the insertion rod 801 moves toward the inside of the support rod 7, and then, the end of the support rod 7 is inserted into the inner side of the limiting column 6, the control block 805 is released, and the support rod 7 is rotated.

The servo motor 508 is fixedly connected to the inside of the base 1, and the output end of the servo motor 508 is fixedly connected to one end of the driving rod 507.

[0028] Place the wireless radio frequency module on the surface of the base 1. By means of the inclined surface extrusion of the bottom end of the module on the clamping block 2, the clamping blocks 2 move away from each other. The moving rod 502 and the connecting plate 504 move synchronously, causing the return spring 503 to be compressed and shortened until the module fits against the surface of the base 1. Under the action of the return spring 503, the pre-clamping state of the module is maintained. Then, by rotating the adjusting rod 11, the moving block 10 is driven to move inside the clamping block 2, thereby driving the baffle 9 to move to the end of the module to abut against the third end of the module. Then, start the servo motor 508 to drive the driving rod 507 to rotate, causing the slider 506 to move inside the base 1, moving the towing rope 505, and pulling the connecting plate 504 closer to the fixing plate 501, so that the clamping blocks 2 tightly clamp the module, preventing the module from shifting during the detection process and facilitating the quick clamping of modules of different sizes.

[0030] Move the control block 805 downward. Under the action of the control rope 806, the driving block 804 moves downward. The inclined plane at the bottom end of the inner side of the driving block 804 and the inclined plane of the push block 802 are mutually extruded, so that the plug rod 801 moves toward the inside of the support rod 7. Then, insert the end of the support rod 7 into the inside of the limiting column 6, release the control block 805, and rotate the support rod 7. Under the action of the compression spring 803, when the plug rod 801 is aligned with the jack 12, the plug rod 801 is inserted into the inside of the jack 12, and the support rod 7 can be quickly fixed to the bottom end of the base 1, improving the portability of the device and the quickness of installation.

[0031] Working principle: When in use, first, place the wireless radio frequency module on the surface of the base 1. By means of the inclined surface extrusion of the bottom end of the module and the clamping block 2, the clamping blocks 2 move away from each other, and the moving rod 502 and the connecting plate 504 move synchronously, causing the return spring 503 to be compressed and shortened until the module fits against the surface of the base 1. Under the action of the return spring 503, the pre-clamping state of the module is maintained. Then, by rotating the adjusting rod 11, the moving block 10 is driven to move inside the clamping block 2, thereby driving the baffle 9 to move to the end of the module to abut against the third end of the module. Then, start the servo motor 508 to drive the driving rod 507 to rotate, causing the slider 506 to move inside the base 1, moving the traction rope 505, and pulling the connecting plate 504 closer to the fixing plate 501, so that the clamping block 2 tightly clamps the module; Subsequently, move the control block 805 downward.
