Technical Problem
[0003]经申请人研究发现，现有技术中，在利用旋钮调节显微镜高度时，由于旋钮机构的调节力输入与升降机构的垂直位移输出之间，缺乏力矩解耦设计，将不可避免的侧向扭力传导至光学系统(具体而言，旋钮转动瞬间产生的侧向扭力导致显微镜镜头发生水平面的偏移角)，从而使得观察视野发生偏移，由此使得精密目标(如0.2mm锡球)脱离视野
Benefits of technology
[0027]依据本发明实施例公开的一种电子维修显微镜升降组件、支架和显微镜，轴向设置有齿轮轴的调节座轴向包覆固定座，以相对于固定座轴向上下移动；调节座与用于固定显微镜光学模组框架固定连接，从而使得光学模组的线束固定在调节座上；而调节旋钮可旋转固定在调节座上，因此，当调节旋钮通过啮合齿轮轴驱动调节座相对于固定座轴向上下移动时，调节旋钮也跟随调节座一起上下移动。相对于现有技术中，支架旋钮(调节机构)与升降座体(执行机构)的分离式设计，本申请中，当旋转调节旋钮驱动齿轮轴时，调节旋钮与调节座同步上下移动，使旋钮转动产生的侧向扭力被同步运动抵消，从而避免了长期使用易产生间隙导致晃动的问题，也就是，减小了精密目标脱离视野的概率。并且，由于线束、旋钮都是固定在调节座上，二者能够同步进行上下移动，因此，能够避免一者移动另一者不动所带来的机构干涉问题，也就是，减小了旋钮与线束缠绕的概率。

Abstract
The application discloses an electronic maintenance microscope lifting assembly, a support and a microscope, wherein the assembly comprises a frame for fixing a microscope optical module; a fixing base for sleeving and fixedly connecting on a connecting column; an adjusting base fixedly connected with the frame; the adjusting base axially covers the fixing base to move up and down relative to the fixing base; the adjusting base is axially provided with a gear shaft; an adjusting knob is rotatably fixed on the adjusting base, the adjusting knob drives the adjusting base to move up and down relative to the fixing base through the meshing gear shaft, and during the movement, the adjusting knob moves up and down together. Therefore, in the process of adjusting the height of the microscope, the probability of the precise target out of the field of view and the winding of the knob and the wire is reduced.
