[0032] Embodiment 2:
[0033] like Figure 7As shown, in the utility model, a limiting groove B402 is embedded above the sliding frame C401, and there are several limiting grooves B402, which are equidistantly arranged in parallel in a semicircular shape. A damping telescopic rod B403 is fixedly installed on the front and rear sides above the inner wall of the slide 4, and a spring is provided on the outer side of the damping telescopic rod B403. A limiting block B404 is fixedly installed below the end of the damping telescopic rod B403, and the limiting block B404 is arranged in a semicircular shape, and the limiting block B404 fits and slides on the inner side of the limiting groove B402.

Compared with the first embodiment, the limiting effect is better.
[0034] Working principle: First, when the staff needs to drill holes on the surfaces of several LED screen shells of the same specifications, they carry several LED screen shells to the workbench 1, turn on the servo motor of the leather conveyor belt 2 to drive the matching transmission roller to drive the leather conveyor belt 2. At the same time, the staff pushes the two sliding blocks 302 to slide inside the adjustment groove 301, squeezes the limit block A307 to slide out of the limit groove A303, and drives the damping telescopic rod A306 and the outer spring to contract, so that the relative guide belts 305 are at a suitable distance, and the damping telescopic rod A306 and the outer spring pop out the limit block A307 to slide into the inner side of one of the relative limit grooves A303, and after the sliding block 302 is limited, After adjusting the other two sliding baffles 302 to the same spacing in the same way, the LED screen shell is placed at the end of the leather conveyor belt 2 in turn, so that when the leather conveyor belt 2 drives the LED screen shell to be transported to the other end, the LED screen shell will be between the guide belts 305 at the same time, driving the guide belts 305 to transmit through the rotating rollers 304, driving the LED screen shell to perform limit guiding, which can avoid the LED screen shell from being offset during transportation and affecting the subsequent drilling position misalignment. Then, after one of the LED screen shells is transported to the bottom of the fixed frame A101, the staff turns off the servo motor of the leather conveyor belt 2, and presses the LED screen shell through the pressing plate 502. It is necessary to adjust the pressing plate 502. When the position is reached, the staff pushes the sliding frame C401 to slide in the opposite direction on the inner side of the sliding groove 4, squeezing the limit block B404 to slide out of the limit groove B402, and driving the damping telescopic rod B403 and the outer spring to contract, driving the two pressing plates 502 to move to the upper sides of the LED screen housing respectively, and the damping telescopic rod B403 and the outer spring pop-up limit block B404 slide into the inner side of the limit groove B402, limiting the sliding frame C401 as a whole. Finally, the staff twists the two adjusting screws 503 to rotate in the inner thread of the thread groove 405, driving the pressing frame 5 to lower the pressing plate 502 to contact the upper sides of the LED screen housing. At the same time, after the telescopic rod 501 and the outer spring are fully contracted, the telescopic rod 501 and the outer spring will generate thrust on the pressing plate 502, so that the pressing plate 502 can more firmly limit and press the LED screen shell. Then, the staff will control the screw slide rail A102 and the screw slide rail B105 to drive the drill bit 108 to move to the position where drilling is required above the LED screen shell through the slider, turn on the servo motor 107 to drive the drill bit 108 to rotate, and control the electric telescopic rod 103 to lower the drill bit 108 to contact the LED screen shell for drilling. Then, in the same way, several designated drilling positions above the LED screen shell are drilled, and the servo motor matching the leather conveyor belt 2 is turned on to transport the other LED screen shells to the bottom of the fixed frame A101 for processing.
