At this time, the computer hardware will be in a suspended state. When performing a vibration test later, the shaken-off electronic components can directly detach from the surface of the computer hardware, thereby reducing the occurrence of collisions between the detached electronic components and components on the surface of the computer hardware.

[0037] A pull groove for inserting fingers is provided on the back of the rectangular frame 23 . The pull groove makes it easy to insert fingers into and pull the rectangular frame 23 .

[0038] Baffles 35 for shielding the first through slots are fixedly connected to both side surfaces of the base 4. The baffles 35 can prevent the shaken-off electronic components from falling to the ground and being contaminated.

[0039] The test bench 1 is provided with a driving mechanism, which is used to drive the base 4 to move horizontally and the placement mechanism to vibrate. The driving mechanism includes two first right-angle plates 11 slidably connected to the test bench 1. The upper surfaces of the two first right-angle plates 11 are provided with grooves adapted to the third support plate 13. The outer surfaces of the two first right-angle plates 11 are fixedly connected with two first springs 12, and the other ends of the first springs 12 are fixedly connected to the bottom surface of the test bench 1. A first rotating shaft 8 is rotatably installed between one of the first support plates 2 and one of the second support plates 3, and a second rotating shaft 9 is rotatably installed between the other first support plate 2 and the other second support plate 3. The first rotating shaft 8 and the second rotating shaft 9 are rotatably installed. The outer surface of the moving shaft 9 is fixedly connected with the fifth synchronous wheel 22, and the two fifth synchronous wheels 22 are connected by the third synchronous belt transmission. The outer surfaces of the first rotating shaft 8 and the second rotating shaft 9 are fixedly connected with a group of cams 10, and the two groups of cams 10 are respectively located under the two first right-angle plates 11. A second through groove adapted to the third support plate 13 is opened inside the test bench 1, and the second through groove is connected with the first rectangular slide groove. When the driving base 4 moves to the left to the maximum extent, the two third support plates 13 on the right will be slidably connected in the two notches respectively. When the driving base 4 moves to the right to the maximum extent, the two third support plates 13 on the left will be slidably connected in the two notches respectively.

[0040] The driving mechanism also includes a shell 14 with an opening on the left side, the left side surface of the shell 14 is fixedly connected to the right side surfaces of the two second support plates 3, a motor 15 is installed on the right side surface of the shell 14, the output end of the motor 15 passes through the shell 14 and is rotatably connected to the inside of one of the second support plates 3, the outer surface of the output end of the motor 15 is fixedly connected to the first synchronous wheel 16 and the third synchronous wheel 19, the outer surface of the reciprocating screw 7 located at the outer part of the U-shaped plate 6 is installed with a first one-way bearing 18, the first one-way bearing 18 is installed with a second synchronous wheel 17, and the second synchronous wheel 17 and the first synchronous wheel 16 are connected through a first synchronous belt transmission, the outer surface of the second rotating shaft 9 is installed with a second one-way bearing 21, and the second one-way bearing 21 rotates in the opposite direction to the first one-way bearing 18, the second one-way bearing 21 is installed with a fourth synchronous wheel 20, and the fourth synchronous wheel 20 is connected to the third synchronous wheel 19 through the second synchronous belt transmission, and the motor 15 is started, so that the motor 15 drives the first synchronous wheel 16 and the third synchronous wheel 19 to rotate forwardly. The forward rotation of the first synchronous wheel 16 can drive the second synchronous wheel 17, the first one-way bearing 18 and the reciprocating screw rod 7 to rotate forwardly synchronously. When the third synchronous wheel 19 rotates forward, it will only drive the fourth synchronous wheel 20 to rotate idly, and will not drive the second rotating shaft 9 to rotate accordingly. The motor 15 is started, so that the motor 15 drives the first synchronous wheel 16 and the third synchronous wheel 19 to rotate in the opposite direction. The reverse rotation of the third synchronous wheel 19 can drive the fourth synchronous wheel 20, the second one-way bearing 21, the second rotating shaft 9 and the first rotating shaft 8 to rotate in the opposite direction synchronously. When the first synchronous wheel 16 rotates in the opposite direction, it will only drive the second synchronous wheel 17 to rotate idly, and will not drive the reciprocating screw rod 7 to rotate accordingly.

[0041] Working principle: First, place the computer hardware to be tested on the fixed plate 26, then turn the knob forward, the knob can drive the threaded rod 33 to rotate forward, the forward rotation of the threaded rod 33 can drive the second threaded plate 34 and the movable plate 27 to move horizontally in the direction of the computer, when the movable plate 27 drives one of the second right-angle plates 28 to move to clamp the computer hardware, turn down the two screws 30 in sequence to press and fix the computer hardware, then pull the pull plate 36 away from the placement plate 24, the pull plate 36 can drive the limit rod 37 away from the placement plate The second spring 38 is stretched in the direction of the limit rod 37. When the limit rod 37 is completely removed from the inside of the limit hole, the placement plate 24 can be rotated 180 degrees and the pull plate 36 is released. Under the action of the second spring 38, one end of the limit rod 37 will be inserted into the inside of the limit hole, thereby limiting the placement plate 24. At this time, the computer hardware will be in a suspended state. When the vibration test is performed later, the shaken-off electronic components can be directly detached from the surface of the computer hardware, thereby reducing the collision between the detached electronic components and the components on the surface of the computer hardware.

[0042] Then start the motor 15, so that the motor 15 drives the first synchronous wheel 16 and the third synchronous wheel 19 to rotate forward. The forward rotation of the first synchronous wheel 16 can drive the second synchronous wheel 17, the first one-way bearing 18 and the reciprocating screw 7 to rotate forward synchronously. When the third synchronous wheel 19 rotates forward, it will only drive the fourth synchronous wheel 20 to rotate idly, and will not drive the second rotating shaft 9 to rotate accordingly. The rotation of the reciprocating screw 7 can drive the first threaded plate 5, the base 4 and the placement mechanism to move horizontally along the reciprocating screw 7. When the base 4 moves to the right to the maximum extent, the computer hardware to be tested will move to the top of the test bench 1, and then the motor 15 drives the first synchronous wheel 16 and the third synchronous wheel 19 to rotate in the opposite direction. The reverse rotation of the third synchronous wheel 19 can drive the fourth synchronous wheel 20, the second one-way bearing 21, the second rotating shaft 9 and the first rotating shaft 8 to rotate in the opposite direction synchronously. When the first synchronous wheel 16 rotates in the opposite direction, it will only drive the second synchronous wheel 17 to rotate idly, while It will not drive the reciprocating screw rod 7 to rotate accordingly. The rotation of the first rotating shaft 8 and the second rotating shaft 9 can drive the two sets of cams 10 to rotate. The rotation of the cam 10 can drive the first right-angle plate 11, the placement mechanism and the computer hardware to move upward. When the cam 10 rotates to no longer contact the first right-angle plate 11, under the action of the first spring 12 and gravity, the first right-angle plate 11, the placement mechanism and the computer hardware will move downward to reset, so that the continuous rotation of the cam 10 can drive the computer hardware to move up and down reciprocatingly, thereby performing a vibration test on the computer hardware. During the vibration test of the computer hardware, loading and unloading operations can be performed on another computer hardware at the same time. When the test is completed, the motor 15 can be controlled to rotate forward again to move the base 4 to the left to the maximum extent, so that the vibration test can continue to be performed on another computer hardware, thereby effectively improving the continuity of the entire test process and greatly improving the test efficiency.
