The clamping assembly is fixedly installed at the upper end of the connecting sleeve plate. The clamping assembly includes a fixed block, an abutting block, a spring, a sleeve rod and a circuit board. The bottom of the fixed block is fixedly connected to the upper end of the connecting sleeve plate. There is a certain gap between the fixed block and the upper end of the fixture main body. A set of mounting frames is fixedly installed on one side of the fixed block. There is a gap between the mounting frame and the fixture main body. One end of multiple springs is fixedly connected to the side wall of the mounting frame. The springs are located outside the sleeve rod. One end of multiple sleeve rods is fixedly connected to the side wall of the mounting frame. One side of the abutting block is fixedly connected to one end of the sleeve rod. The center position of one side of the abutting block is fixedly connected to one end of the spring. The circuit board is placed at the center position of the upper end of the fixture main body and is located between two fixed blocks.

[0017] In order to make the technical method, creative features, achieved objectives and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0018] As Figures 1-4 shown, in view of the problems in the prior art, the present utility model provides a fixture for testing the performance of a storage circuit board, including a fixture main body 1. The clamping assembly 3 is fixedly installed at the upper end of the connecting sleeve plate 212. The clamping assembly 3 includes a fixed block 310, an abutting block 312, a spring 313, a sleeve rod 314 and a circuit board 315. The bottom of the fixed block 310 is fixedly connected to the upper end of the connecting sleeve plate 212. There is a certain gap between the fixed block 310 and the upper end of the fixture main body 1. A set of mounting frames 311 are fixedly installed on one side of the fixed block 310. There is a gap between the mounting frames 311 and the fixture main body 1. One end of each of the multiple springs 313 is fixedly connected to the side wall of the mounting frame 311. The springs 313 are located outside the sleeve rods 314. One end of each of the multiple sleeve rods 314 is fixedly connected to the side wall of the mounting frame 311. One side of the abutting block 312 is fixedly connected to one end of the sleeve rod 314. The center position of one side of the abutting block 312 is fixedly connected to one end of the spring 313. The circuit board 315 is placed at the center position of the upper end of the fixture main body 1 and is located between the two fixed blocks 310.
[0019] Preferably, a set of pushing components 2 are fixedly installed inside the fixture main body 1. The pushing components 2 include a motor 210, a threaded rod 211, a connecting sleeve plate 212, a connecting plate 213, a hub 214 and a slide rail 215. The slide rail 215 is fixedly installed on the inner bottom plate of the fixture main body 1. The upper middle positions on both sides of the connecting sleeve plate 212 are slidably connected to the chutes opened at the upper end of the fixture main body 1. Both of the two connecting sleeve plates 212 are threadedly connected to the threaded rod 211. The two threaded rods 211 are symmetric to each other. The threads at both ends of the threaded rod 211 are opposite. One end of the threaded rod 211 is fixedly connected to the output shaft of the motor 210. The other end of the motor 210 is rotatably connected to one side wall of the fixture main body 1. A set of connecting plates 213 are fixedly connected to the bottom of the connecting sleeve plate 212. A hub 214 is installed at the bottom of the connecting plate 213. The hub 214 is slidably installed inside the slide rail 215. Both sides of the connecting plate 213 are also slidably connected inside the slide rail 215.
[0020] (1) In the present utility model, after the initial clamping is completed, if the two sides of the circuit board 315 are regular rectangular shapes, then multiple sets of abutting blocks 312 are on the same horizontal straight line. If the two sides of the circuit board 315 are irregular shapes, then the protruding parts on the side walls of the circuit board 315 will push the abutting blocks 312 and squeeze the springs 313, thereby clamping the circuit board 315 more firmly to adapt to the irregular circuit board 315 and prevent the need to frequently replace or adjust the fixture when detecting circuit boards 315 of various different specifications, sizes, and shapes, effectively improving the work efficiency.
[0021] (2) In the present utility model, the circuit board 315 to be detected is placed at the center of the upper end of the fixture main body 1, and then the motor 210 is started. At this time, the motor 210 drives the threaded rod 211 to rotate, and the threaded rod 211 pushes the connecting sleeve plate 212 to slide in the chute opened at the upper end of the fixture main body 1 and drives the hub 214 to slide in the slide rail 215. Since the threads at both ends of the threaded rod 211 are reverse, the two sets of connecting sleeve plates 212 will gradually approach. When the connecting sleeve plate 212 drives the fixed block 310 to move to the position where the abutting block 312 abuts against the side wall of the circuit board 315, the motor 210 stops moving. The clamping distance can be adjusted according to the size of the circuit board 315, and it can adapt to circuit boards 315 of various different sizes.
[0022] Working principle: First, the circuit board 315 to be detected is placed at the center of the upper end of the fixture main body 1, and then the motor 210 is started. At this time, the motor 210 drives the threaded rod 211 to rotate, and the threaded rod 211 pushes the connecting sleeve plate 212 to slide in the chute opened at the upper end of the fixture main body 1 and drives the hub 214 to slide in the slide rail 215. Since the threads at both ends of the threaded rod 211 are reverse, the two sets of connecting sleeve plates 212 will gradually approach. When the connecting sleeve plate 212 drives the fixed block 310 to move to the position where the abutting block 312 abuts against the side wall of the circuit board 315, the motor 210 stops moving. The clamping distance can be adjusted according to the size of the circuit board 315, and it can adapt to circuit boards 315 of various different sizes. At this time, if the two sides of the circuit board 315 are regular rectangular shapes, then multiple sets of abutting blocks 312 are on the same horizontal straight line. If the two sides of the circuit board 315 are irregular shapes, then the protruding parts on the side walls of the circuit board 315 will push the abutting blocks 312 and squeeze the springs 313, thereby clamping the circuit board 315 more firmly to adapt to the irregular circuit board 315 and prevent the need to frequently replace or adjust the fixture when detecting circuit boards 315 of various different specifications, sizes, and shapes, effectively improving the work efficiency.
