偏角基座14内部设计有赤纬轴9安装腔，赤纬轴9固定安装在偏角基座14内部，在赤纬轴9的内壁径向设计有张紧通孔，张紧通孔内部设置有张紧块组件，偏角锁紧块19呈圆锥形块状，在赤纬轴9的上端设计有锁紧块安装腔，偏角锁紧块19放置在赤纬轴的锁紧块安装腔内，在偏角锁紧块19上方设计有偏角锁紧手柄20，偏角锁紧手柄20与偏角锁紧块19固定连接，在偏角锁紧手柄20上固定连接有镜筒座11，在赤纬轴9的上下各设置安装了时角基座轴承3，时角基座轴承套3在赤纬轴9上与赤纬轴9固定连接，在上方的时角基座轴承3的上方设计有偏角蜗轮并圈7，在下方的时角基座轴承3的下方设计有赤纬轴并圈4，在 偏角蜗轮并圈7的上方设置有偏角蜗轮13，且在偏角蜗轮13与偏角蜗轮并圈7之间以及偏角蜗轮13与赤纬轴2之间设计有铜垫片8，偏角蜗轮13套在赤纬轴9上与赤纬轴9固定连接，偏角蜗轮13的左侧设计有偏角蜗杆5，偏角蜗杆5与偏角蜗轮13啮合连接；
偏角基座14呈长方体，在偏角基座14的下方两端设计有两个连接架，时角基座1位于偏角基座14的下方，赤经轴2通过定位组件与时角基座固定连接，赤经轴2贯穿了偏角基座14下方两端的连接架与时角基座1，在赤经轴2的两端与偏角基座14连接架交汇处设计有时角基座轴承3，时角基座轴承3与赤经轴2之间固定连接，通过赤经轴2将偏角基座14与时角基座1都连接在一起，赤经轴2内部设计有时角锁紧手柄安装腔，时角锁紧手柄18安装在时角手柄安装腔内，时角锁紧手柄18下端呈圆锥状，在赤经轴2内部设计了张紧通孔，张紧通孔内部设置有张紧块组件，赤经轴2的右端套有时角蜗轮17，在时角蜗轮的上方设计有时角蜗杆16，时角蜗轮17与时角蜗杆16啮合连接，在时角蜗轮17与赤经轴2之间的左右两侧分别设计有铜垫片8。
所述的张紧块组件分为张紧块A10与张紧块B12，张紧块A10放置在赤纬轴内壁的张紧通孔内，张紧块A10设计有凹形槽，凹槽为梯形状，槽口宽槽底窄，张紧块B12呈梯形块状，张紧块B12正好能与张紧块A10的凹槽相契合，且张紧块B12梯形块较长的那一面设计成倾斜面，与偏角锁紧块下端圆柱形斜边正好相贴合。
所述的在赤纬轴的左右两侧分别设置有电机，两个电机上分别连接有偏角蜗杆组件6与时角蜗杆组件21。
本发明使用时，托架通过两个蜗杆组件(由电机及蜗杆组装而成)驱动蜗轮旋转从而带动偏角机构及时角机构工作，当时角锁紧手柄及偏角锁紧手柄松开时，偏角蜗轮跟赤韦轴脱离，时角蜗轮跟赤经轴脱离，这样可以手动转动时角机构及偏角机构，锁紧则只能两个蜗杆组件带动，锁紧机构方面是将偏角手柄顺时针旋转(偏角手柄及偏角锁紧块通过螺钉固定为一体)从而使带锥度的偏角锁紧块向下移动再推动张紧块B向外张紧由于张紧块带有锥度，从而使张紧块A向两边扩张，最后将偏角蜗轮及赤韦轴抱紧，反之将偏角蜗轮及赤韦轴脱离，时角机构原理同偏角机构，这样的优点是当蜗轮跟轴抱紧时蜗轮不会处现偏心现象，这样跟踪精度更高。
