上述实施例具有如下优点：
1、本LED显示屏前维护工具，其特征在于，包括壳体10、磁性件20、软质保护垫30，此方案中的斜面过渡设计，从无磁性件20的斜面缓慢过渡到有磁性件20的底平面11，既能避免前维护工具有磁性件20的底平面11直接接触LED灯板造成的LED灯珠损坏，又能省去复杂的机械传动和电路设计，使LED屏维护工具的使用操作过程更加简单，同时也杜绝了复杂机械或电路组成带来 的自身故障，更加的易用和耐用；使用时，先将壳体10的斜侧面与LED灯板接触，然后缓慢旋转前维护工具，通过圆弧过渡平缓地过渡到底平面11，使底平面11与LED灯板相接触，底平面11第一凹槽111内的磁性件20对LED灯板的吸附力逐渐增大，通过磁性件20吸住LED灯板后将LED灯板从LED显示屏中取出，当要放下LED灯板时，缓慢旋转前维护工具，使LED灯板从与底平面11接触平缓地过渡到与斜侧面接触，使磁性件20逐渐远离LED灯板，该前维护工具在取出LED显示屏的LED灯板时，其上的磁性件20逐渐缓慢的接触LED灯板，不会直接大力吸住LED灯板，对LED灯珠的损坏，在斜侧面及底平面11上粘合软质保护垫30，有效的防止了前维护时，磁性件20与LED灯板直接接触，软质保护垫30还起到很好的缓冲保护作用，避免了磁性件20直接接触灯面对LED灯珠的损坏。
2、磁性件20通过磁件安装板40相匹配安装在第一凹槽111内，方便磁性件20的安装，使磁性件20安装在第一凹槽111内更为稳定，优选的，磁件安装板40采用铁板制成，将磁性件20固定在铁板上，通过磁性件20将铁板磁化，增强了整体的磁力，减少了磁性件20的用量，降低了成本。
3、把磁性件20按一定的排列预先安装在磁件安装板40的磁件固定板上，然后再通过磁件安装板40的第一安装板、第二安装板安装在第一凹槽111内，方便磁性件20的组装，提高生产率。
4、壳体10包括壳主体12、壳盖13，壳盖13的设置，便于使用者使用操作。
5、优选的，壳主体12采用塑胶材料制成，相比于传统的金属件壳体，既能有效地减轻重量，又适合大批量低成本生产。
6、壳盖13包括盖板131、把手132，使用者使用前维护工具时，方便使用者通过提拉把手132将LED显示屏的LED灯板取出。
7、本LED显示屏前维护工具还包括第一螺杆51、第二螺杆52，第一螺杆51、第二螺杆52分别依次穿过磁件安装板40、第一凹槽111、盖板131的通过与把手132的两端连接，将第一螺杆51、第二螺杆52隐藏在内部，大大简 化了装配过程，提高了整体的美观性。
8、本LED显示屏前维护工具还包括沉头螺丝60，磁性件20通过沉头螺丝60安装在磁件安装板40上，使磁性件20的安装更为稳固，安全。
9、沉头螺丝60采用铁镀黑锌沉头螺丝60，提高沉头螺丝60的防氧化性能。
10、多个侧面至少包括第一侧面14、第二侧面15，第一侧面14、第二侧面15为斜侧面，双斜侧面过渡设计，方便使用者从两个方向平缓地过渡。
11、软质保护垫30粘合在所述第一侧面14、第二侧面15、底平面11上，方便操作者从第一侧面14或第二侧面15平缓过渡到底平面11上。
12、磁性件20为磁铁，取材方便，磁性稳定。
13、磁性件20至少包括第一磁铁及第二磁铁，优选的磁性件20包括第一磁铁、第二磁铁及第三磁铁，第一磁铁、第二磁铁及第三磁铁呈三角形分布，第一磁铁、第二磁铁及第三磁铁从三个不同部位对LED灯板进行吸取，使LED灯板与前维护工具的吸附稳定牢固，防止LED灯板在取出的过程中掉落。
14、优选的，磁性件20包括第一磁铁、第二磁铁、第三磁铁、第四磁铁、第五磁铁、第六磁铁，第一磁铁、第二磁铁、第三磁铁、第四磁铁、第五磁铁、第六磁铁呈环形分布，使LED灯板与前维护工具的吸附更稳定牢固。
15、优选的，第一磁铁、第二磁铁、第三磁铁、第四磁铁、第五磁铁、第六磁铁的极性排布呈环形NSNSNS极性交错排布，相邻磁铁面呈NSNSNS极性交错分布，磁铁极性的交错分布在解决了安装时磁铁排斥问题的同时，也更有利于磁铁吸力的增强，减少了磁铁的用量。
16、软质保护垫30采用泡棉板，对灯面的缓冲保护作用性能更佳。
