After the salt spray test of the material is completed, a plurality of water droplets may condense at the lower end of the placement rod 402. When the sealing cover 300 is opened upward, the ejection assembly is triggered to drive the sliding seat 404 to move upward rapidly, and at the same time, the sliding seat 404 is vibrated to a certain extent, thereby vibrating the placement rod 402 clamped above the sliding seat 404 to a certain extent, and the water droplets condensed at the lower end of the placement rod 402 are vibrated to the bottom end of the salt spray equipment 100, thereby reducing the corrosion caused by the condensed water droplets dripping on the device or the ground when the placement rod 402 is taken out and placed, thereby enhancing the safety of the device during use, improving the quality of the working environment, and reducing the damage to the staff or the device.

[0035] Working principle: First, energize the electromagnet 419 to generate magnetism, and the electromagnet 419 quickly attracts and fits with the permanent magnet 420 below, driving the sliding seat 404 to move downward, and then multiple placement rods 402 are placed on the upper ends of the two clamping blocks 405, and the placement rods 402 are pressed downward to apply downward pressure on the two clamping blocks 405, so that the two clamping blocks 405 open each other, so that the placement rods 402 are pressed into the arc groove 406, and then when the two clamping blocks 405 are released from the pressure of the placement rods 402, the two clamping blocks 405 approach each other to reset, clamp and fix the placement rods 402, and place multiple placement frames 401 in the placement groove 417.

[0036] Then the material to be tested is placed on the placement frame 401 and the placement rod 402, and the sealing cover 300 is pressed downward. When the sealing cover 300 is pressed downward, the lower pressure column 411 is driven to move downward, pressing the lower pressure block 409 downward, and the lower pressure block 409 drives the upper wedge block 410 to move downward. The upper wedge block 410 presses the lower wedge block 407 downward, driving the lower wedge block 407 to approach one side of the sliding seat 404, driving the insert block 408 to move and insert into the sliding seat 404, and limiting and fixing the sliding seat 404. Then the electromagnet 419 is powered off, so that the electromagnet 419 loses its magnetism. The electromagnet 419 no longer attracts the permanent magnet 420, so that the sliding seat 404 can move freely and break away from the limit of the sliding seat 404. Then the console 200 controls the salt spray equipment 100 to start the salt spray test on the material inside.

[0037] After the salt spray equipment 100 has finished testing the material, the sealing cover 300 is rotated upward to open, driving the lower pressure column 411 to move upward, and the lower pressure column 411 is released from the downward pressure on the lower pressure block 409, and then the lower pressure block 409 moves upward, driving the upper wedge block 410 to move upward, and then the upper wedge block 410 is released from the downward pressure on the lower wedge block 407, and the lower wedge block 407 is reset to the side away from the sliding seat 404 by the compression spring, and then drives the plug block 408 to be pulled out to the side away from the sliding seat 404, and the plug block 408 is released from the limit of the sliding seat 404, and the sliding seat 404 moves upward rapidly, driving the clamping block 405 The clamped placement rod 402 moves upward, and the sliding seat 404 moves upward, driving the striking block 414 to move upward. The striking block 414 moves upward quickly to hit the upper force block 415, causing the sliding seat 404 to vibrate, and at the same time causing the placement rod 402 to vibrate, thereby vibrating the water droplets condensed at the lower end of the placement rod 402 to fall to the bottom end of the salt spray equipment 100, reducing the condensed water droplets dripping on the device or the ground when the placement rod 402 is taken out and placed, causing certain corrosion to the device, thereby enhancing the safety of the device during use, improving the quality of the working environment, and reducing certain damage to the staff or the device.
