[0029] Through the above technical solution, by placing an object on the rotating seat 401 on the workbench 3, starting the motor 402 can drive the screw rod 403 to rotate and at the same time drive the moving block 404 to move. Because the threads on both sides of the screw rod 403 rotate in opposite directions, and the two moving blocks 404 are symmetrically arranged on both sides of the screw rod 403, the two moving blocks 404 can move relative to each other, driving the two clamping plates 406 on the first spring 405 to move inward to clamp and fix the object, and the elastic effect of the first spring 405 is used to prevent the clamping force from being too large to damage the object. The position of the rotating seat 401 can be fixed by the positioning rod 408 extending into the positioning groove 407, thereby achieving the effect of limiting the object.

[0030] Specifically, a suction fan 5 is fixedly connected to the top of the chassis 1 , and a suction pipe 6 is provided at the bottom of the suction fan 5 , and a control mechanism 7 is installed on the front of the chassis 1 .

[0031] Through the above technical solution, it is convenient to control the operation of the suction fan 5 through the control mechanism 7. Starting the suction fan 5 can extract the moisture in the chassis 1 outward through the suction pipe 6 to avoid excessive moisture in the test box.

[0039] Through the above technical solution, the fixing rod 802 can be extended into the fixing groove 801 under the action of the second spring 804 to fix the position of the workbench 3. Pulling the pull rod 805 by hand can move the baffle 803 outward, and the second spring 804 is compressed to make the fixing rod 802 disengage from the fixing groove 801, releasing the limit fixation of the workbench 3, thereby achieving the effect of installing and disassembling the workbench 3.

[0040] Specifically, there are two rollers 807 , and the rollers 807 are symmetrically arranged with the mid-perpendicular line of the workbench 3 as the symmetry axis.

The first spring 405 can buffer the pressure to prevent excessive pressure from causing damage to the article. When adjusting the direction of the article, pull the positioning rod 408 outward for a distance and select the appropriate positioning rod. After the workbench 3 is disassembled, the pull rod 805 is pulled by hand, and the pull rod 805 drives the baffle 803 to move outward, and the baffle 803 drives the fixing rod 802 to move outward, so that the fixing rod 802 disengages from the fixing groove 801, releasing the limit fixation of the workbench 3, and then the workbench 3 is moved outward. The workbench 3 slides in the slide groove 806 through the roller 807, and then the workbench 3 can slide out of the test box, making it easy to slide the workbench 3 out of the test box for maintenance and inspection.
