[0024] In this embodiment: guide blocks 406 are fixedly installed on the outer walls of both sides of the collection box 401, and guide rails 407 are set on both sides of the collection box 401. The outer wall on the side where the two guide rails 407 are close to each other is provided with a guide groove for the guide block 406 to slide back and forth, and a fixing plate 408 is fixedly installed on the top of the guide rail 407. Three fixing holes 409 distributed front and back are opened inside the fixing plate 408, and the fixing plate 408 is fixedly connected to the experimental table 1 through the fixing holes 409.

[0028] In this embodiment: the slider 603 is internally threaded with a second screw rod 606 , both ends of the second screw rod 606 are rotatably connected to the support seat 601 , a drive motor 607 is fixedly mounted on the top of the second screw rod 606 , and the drive motor 607 is fixedly mounted on the upper surface of the support seat 601 .
